• General Overview
  • Central Thesis
    • Root confusion: philosophy spatializes the unextended, turning quality into quantity and duration into space.
    • Two multiplicities: material things are discrete and countable; conscious states interpenetrate and are qualitative.
    • Intensity is quality: “more intense” is a qualitative shade, not a measurable magnitude.
    • Pure duration: succession without externality, where states melt into one another.
    • Free will test case: dissolving spatial illusions dissolves the determinism–free-will problem.
  • Intensity
    • Deep psychical states: joy, sorrow, pity, aesthetic feelings pass through qualitative stages, not degrees.
    • Effort illusion: muscular effort is peripheral sensation spreading through the body, not psychic force.
    • Sensation and cause: representative sensations borrow quantity from external causes; affective states reflect inner multiplicity.
    • Psychophysics critique: Weber–Fechner laws mark stimulus thresholds, never measure sensation magnitude.
    • Delbœuf’s rings: equal contrasts assume what they try to prove; elementary contrasts are qualitative differences.
  • Duration and Multiplicity
    • Number needs space: counting requires identical units set side by side in homogeneous space.
    • Conscious multiplicity: psychic states form a confused qualitative multiplicity only analysis separates.
    • Pure duration: heterogeneous, continuous, interpenetrating; homogeneous time is the ghost of space.
    • Succession implies space: representing a series as a line secretly imports spatial intuition.
    • Clock time: we count simultaneities, not duration; measurable time is a spatial symbol.
  • The Self
    • Two selves: a fundamental self of interpenetrating states, and a shadow self objectified for social life.
    • Language solidifies: fixed words equate the ever-becoming feeling with its permanent object.
    • Depth vs surface: associationism fits dead surface ideas, not living beliefs fused with the whole self.
    • Deep feelings: a feeling reflects the whole soul, so being determined by it is being self-determined.
    • Free act: the whole personality expresses itself, like the artist and his work.
  • Determinism and Freedom
    • Physical determinism: reduces to psychological determinism; energy conservation cannot bind conscious duration.
    • Associationist determinism: reconstructs antecedents after the act; the new idea is cause, not effect.
    • Deliberation as illusion: spatial metaphors of possible paths misread the living, changing self.
    • Freedom admits degrees: parasitic selves, habits, and automatism cover the free core.
    • Predicting free acts: to know all conditions would be to live the act, not foresee it.
  • Causality and Prediction
    • Causality equivocation: empirical succession and mathematical prefiguring are distinct; determinists blend them.
    • Mechanical physics: dissolves matter into homogeneous extensity and algebra, losing real duration.
    • Dynamic causality: future act is prefigured as possibility; the enduring self grounds real freedom.
    • Time and space: freedom lives in time flowing, not in time flown and represented as space.
    • Scientific limits: science keeps simultaneity and position, but cannot express becoming.
  • Conclusion
    • Purified ideas: intensity, duration, and determination, freed from space, reveal consciousness as quality.
    • Kant’s error: mistaking duration for its spatial symbol banished freedom beyond knowledge.
    • Freedom indefinable: it is a process, not a thing; analysis turns it into a spatial symbol.
    • Automatism’s cover: crystallized states and fixed associations hide freedom in ordinary life.
    • Final resolution: free act is the concrete self recovering itself in pure duration.
• Deep Dive
  • Translator's Preface
    • Intuition, Not Concepts
      • Realism of flux: reality is immediate experience, continuous becoming, grasped by intuition
      • Conceptual method: dominant tradition in philosophy, builds by abstract thought
      • Concepts: break the continuous flow into parts external to one another
      • Practical value: concepts serve language, social life, practical purposes
      • Failure: concepts substitute dead fragments, produce insoluble intellectualist puzzles
    • Duration and Multiplicity
      • Intensity: conscious states are purely qualitative, not quantitative
      • Quantity: applies only to magnitudes, ultimately to space
      • Two multiplicities: discrete quantitative multiplicity involves space; conscious states are wholly qualitative
      • Duration: unfolding multiplicity, succession without distinction, interpenetration of heterogeneous states
      • No recurrence: former states can never recur in pure duration
      • Measurable time: artificial concept from the intrusion of space into duration
      • Root error: confusing concrete duration with abstract time of mathematics, physics, language
    • Freedom and the Living Self
      • Free will problem: difficulties arise from analyzing the act after it is performed
      • Conceptual stand: taking up a post-act standpoint creates the illusion of determinism
      • Freedom: from the living, developing self, freedom is a clear fact of observation
      • Indefinable: freedom cannot be captured in abstract or conceptual terms
  • Author's Preface
    • Language and Spatial Thought
      • Words impose false precision: language demands sharp distinctions like those between material objects.
      • Spatial thinking is practical: useful for daily life and necessary in most sciences.
      • Hidden cost: philosophy errs by placing side by side in space what does not occupy space.
    • The Root of Philosophical Contradictions
      • Illegitimate translation: the unextended is turned into the extended, quality into quantity.
      • Contradiction enters the question: once smuggled in, it inevitably reappears in the answer.
      • The remedy: get rid of the clumsy symbols around which the fight is waged.
    • Free Will as a Test Case
      • Framing the problem: free will is common to metaphysics and psychology.
      • The real confusion: determinists and opponents both conflate duration with extensity, succession with simultaneity, quality with quantity.
      • A dissolving solution: dispel the confusion and objections, definitions, and the problem itself may vanish.
    • Structure of the Work
      • Third chapter as core: contains the proof concerning free will.
      • First two chapters support it: analyses of intensity and duration serve as introduction.
  • The Intensity of Psychic States
    • Intensity, Magnitude, and Qualitative Change (The Intensity of Psychic States · I)
      • The Puzzle of Intensive Magnitude
        • Quantitative talk: Common sense and psychophysicists assume sensations, feelings, efforts can be more intense, even twice as intense.
        • Extensive magnitude: Greater means contains the lesser; clear for numbers and bodies, but not for intensities.
        • Container metaphor: Common sense pictures intensive effort as rolled-up thread or compressed space; only a metaphor.
        • Two kinds of quantity: Distinguishing extensive and intensive magnitude evades the issue; both still claim something common.
        • Contradiction: An inextensive quantity cannot contain; if it does, it is divisible and extended.
      • Objective and Mechanical Explanations Fail
        • Objective causes: Define intensity by number and magnitude of measurable causes; works only in simple cases like more light sources.
        • Ignorance of causes: Usually we judge intensity without knowing the cause; the effect often leads us to infer the cause.
        • Inner states: Deep psychic phenomena have no external measurable cause, yet clearly differ in intensity.
        • Atomic movements: Kinetic theories reduce intensity to molecular motion, but consciousness gives us sensation, not movement.
        • Intensity remains property: We infer work from sensation, not vice versa; the question of why greater means more space remains.
      • Deep-Seated Psychic States Are Qualitative
        • Pure intensity: Deep joy, sorrow, and passion seem self-sufficient, with no extensive element involved, so should be easier to define.
        • Desire's growth: An obscure desire begins isolated, then permeates more psychic elements, tingeing them with its color.
        • Dynamic alteration: “Filling the soul” means altering the shade of many perceptions, not expanding like a spatial object.
        • Spatializing consciousness: Reflective consciousness prefers clear-cut distinctions, so it misreads qualitative change as magnitude.
        • Hope: Intense hope owes its charm to infinite possible futures; dreams and hope surpass possession and reality.
      • Joy and Sorrow as Qualitative Stages
        • Joy's stages: Joy begins as orientation toward the future, then quickens ideas, finally tinges everything with a novel quality.
        • Counting states: We set divisions between forms of joy and call them intensities, though they are qualitative alterations.
        • Sorrow's stages: Sorrow begins as facing the past and impoverishment; ends as aspiration to nothingness, with bitter pleasure in new misfortune.
        • Gradual transitions: Successive forms of a feeling, divided into intervals, appear as degrees of one changing magnitude.
      • Aesthetic Feelings: Grace and Its Elements
        • Grace: Begins as the perception of ease and facility in outward movements.
        • Foresight: Graceful movements announce future attitudes; curves please because each new direction is prefigured in the preceding.
        • Rhythm and music: Measure lets us foresee the dancer's movements and feel we control them; physical sympathy arises.
        • Moral sympathy: Physical sympathy suggests moral sympathy; higher grace is a virtual, mobile sympathy ready to offer itself.
        • Qualitative progress: Increasing aesthetic intensity is really successive different feelings, each heralded and then eclipsed by the next.
      • Art, Beauty, and Suggestion
        • Method: The beautiful admits degrees; study it first in conscious art, then pass to nature as an artist in its own way.
        • Art's aim: Art puts to sleep our active or resistant powers and makes us responsive to suggested ideas and feelings.
        • Music's power: Rhythm and measure suspend the normal flow; music suggests feelings, while nature merely expresses them.
        • Poetry: Rhythm lulls the soul into self-forgetfulness, so we think and see with the poet.
        • Plastic arts: Fixity imposed upon life carries over to the spectator by physical contagion.
    • Intensity as Suggestion and Muscular Spread (The Intensity of Psychic States · II)
      • Art as Suggestion, Not Expression
        • Art's aim: impresses feelings by suggestion rather than expressing them; dispenses with imitation for more efficacious means
        • Architecture and rhythm: symmetry and repetition lull perception between the same and the same; suspend constant return to personality
        • Sculpture: the stone's pale immobility fixes the expressed feeling forever, absorbing thought and will in its eternity
        • Nature's suggestion: long comradeship lets a slight natural sign arouse sympathy, like a hypnotist's gesture
      • Aesthetic Emotion: Intensity and Elevation
        • No specific feeling: every feeling becomes aesthetic when suggested rather than caused
        • Degrees of intensity: phases are differences of state or nature, not mere degree — akin to hypnosis
        • Degrees of elevation: richness of the suggested feeling; the artist gives us a share in what he cannot make us understand
        • Transmission mechanism: outward signs our body imitates mechanically break the barrier of time and space between consciousnesses
        • Inferior art: art giving only sensations fails because analysis finds nothing beyond the sensation itself
      • Pity and the Moral Feelings
        • Pity's components: putting oneself in another's place; horror of pain alone would make us avoid the wretched
        • Lower forms: La Rochefoucauld's calculation — a shrewd insurance against evils to come
        • True pity: not fearing suffering but desiring it; a need for self-abasement, an aspiration downwards
        • Its charm: detachment from sensuous goods raises us in our own estimation
        • Qualitative progress: increasing intensity moves repugnance → fear → sympathy → humility
      • Muscular Effort and the Illusion of Quantity
        • Vulgar conception: psychic force imprisoned like winds in Aeolus's cave; will regulates its outflow
        • Bain and Wundt: effort as a sensation of outgoing nervous energy or of central innervation
        • James's counter-evidence: paralysis cases show movement executed elsewhere; we sense resulting movement, not expended force
        • Ferrier's trigger finger: effort vanishes when respiration resumes — it coincides with chest fixation, closed glottis
        • Centripetal conclusion: effort is a complex afferent sensation from the periphery — contracted muscles, knit brow, clenched jaws
      • Intensity as Peripheral Spread
        • Definition: increase of effort = more peripheral sensations + a qualitative change in some of them
        • Clenched fist: hand sensation stays identical; effort spreads to arm, shoulder, other limbs, the whole body
        • Pressing lips: sensation unchanged while face, head, then entire body muscles join in
        • Lifting weights: arm sensation remains constant, becoming fatigue then pain; subject mistakes bodily spread for increased force
      • Attention and Violent Emotions
        • Attention's movements: Ribot's frontal muscle, Fechner's scalp tension; intensity is a muscular contraction spreading further
        • Violent emotions: acute desire, anger, love, hatred — muscular contractions co-ordinated by the unreflective idea of acting
        • Darwin's rage: accelerated heart, heaving chest, trembling, clenched teeth; the idea of fighting gives direction
        • Irreducible element: the idea of striking survives even when emotion is mostly organic disturbance
        • Restrained rage: concealing movements concentrates consciousness on them; eliminate all organic disturbance and anger has no intensity
        • Spencer's fear: cries, palpitations, tremblings are part of terror itself, allowing its degrees of intensity
    • Intensity as Masked Multiplicity (The Intensity of Psychic States · III)
      • Emotions: Surface and Depth
        • Emotional intensity: reflex movements and peripheral sensations begun by the organism, not a purely inner force.
        • Deep feelings: as emotion gains depth, peripheral sensations yield to ideas, memories, and inner states.
        • No essential difference: violent and deep feelings both consist in a multiplicity of simple states consciousness dimly discerns.
      • Affective Sensations and Organic Disturbance
        • Organic disturbance: greater nervous disturbance cannot transmit magnitude to sensation, since movements and sensations share nothing.
        • Pleasure and pain: signs of what is tending to take place, not psychic translations of past stimulus.
        • Nascent freedom: affective sensation calls forth resistance to automatic reaction by prefiguring future movements.
        • Intensity of affect: consciousness of involuntary movements beginning and outlined within the state.
      • Pain, Pleasure, and the Organism
        • Pain as symphony: intensity grows as more elementary sensations from different bodily points join in.
        • Extent of organism: we estimate pain by the larger or smaller part of the body that sympathizes and reacts.
        • Disgust: the general sensation is the sum of elementary organic disturbances, not merely their expression.
        • Extreme pain: “unbearable” means it urges the organism into a thousand actions to escape.
        • Pleasure as preference: comparing pleasures means feeling the body’s inclination, a set of beginning movements toward one.
        • Inertia of pleasure: keenness is the organism’s rejection of other sensations; without it pleasure would be quality, not magnitude.
      • Representative Sensations and Their Affective Residue
        • Affective residue: many representative sensations keep an affective character, so intensity is measured by reaction called forth.
        • Weak vs strong: weak sensations require effort and attention; strong ones engross or overwhelm and incite reflex movements.
        • Medium intensities: estimated by comparison, persistence, and monopolizing attention, as with a watch ticking at night.
      • Representative Sensations Measured by External Causes
        • External cause: when sensation becomes representative, we associate a definite amount of stimulation with a definite shade of sensation.
        • Transference: the quantity of the cause is transferred into the quality of the effect, making intensity a magnitude.
        • Pin-prick example: the pricking hand’s progressive effort is localized in the pricked hand’s sensation.
        • Sound intensity: measured by the effort we would expend to produce a similar sound; to hear is to speak to oneself.
        • Pitch: higher or lower notes mean greater or less effort of the tensor muscle; intervals reflect discontinuous effort.
    • Qualities Mistaken for Quantities (The Intensity of Psychic States · IV)
      • Sound Pitch and Spatial Height
        • Vertical scale: high notes resonate in the head, low notes in the thorax, so intervals are reckoned spatially.
        • Muscular effort: chest-voice tension spreads over the body, felt as more intense striving.
        • Upward projection: breath expelled upward makes the sound seem to ascend.
        • Physical definition: counting vibrations converts a pure quality into an apparent quantity.
      • Heat, Cold, Pressure, Weight
        • Heat and cold: distinct nerve points suggest a difference of nature, not degree.
        • Intense heat: truly another kind of heat, labelled by approach or by growing bodily surface affected.
        • Affective reactions: they measure the external cause, tempting us to quantify the sensation itself.
        • Pressure and weight: increasing pressure means contact, then pain, then spreading over surrounding regions.
        • Increase of sensation: psychophysics mistakes a quality that represents magnitude for a sensation that is a quantity.
        • Heavy and light: childish yet real generic kinds, with degrees as species.
        • Sympathetic efforts: distant muscles prepare for weight, so the body measures by widespread reactions.
      • Light and Colour
        • Luminous sources: judged by outlines, shadows, number of lights, and affective dazzle.
        • Hue shifts: near light makes violet bluish, green whitish-yellow, red brilliant yellow.
        • Interpretive habit: we declare colour unchanged and call the difference intensity, substituting understanding for sensation.
        • Helmholtz's white: mixed white can stay the same while component sensations change, because daylight itself changes shade.
        • Black and grey: black is real for consciousness; greys are shades, not decreasing intensities of white.
      • Photometric Experiments
        • What is perceived: putting out candles gives a layer of shadow passing over the surface, a new shade of white.
        • Unprejudiced consciousness: decreasing illumination appears as differently coloured shades, not as less light.
        • Discontinuous sensation: physical light may vary without apparent change until a new quality emerges.
        • Physicist's comparison: photometry equates physical effects, using one identical sensation as intermediary.
        • Sensation's role: it serves as an auxiliary unknown, not as a measured quantity in the final result.
      • Delbœuf and Psychophysical Measurement
        • Delbœuf's rings: three grey rings; observers judge when one grey seems equally distant from the other two.
        • Equality questioned: a contrast AB cannot be shown equal to a differently composed contrast BC.
        • Counting shades: memory inserts a roughly equal number of intermediate greys between A-B and B-C.
        • Variable estimates: divergences grow with brightness difference, ranging from 3 to 94 degrees.
        • Underlying assumption: we only know elementary contrasts are successive, never that they are equal quantities.
    • Psychophysics and the Illusion of Quantity (The Intensity of Psychic States · V)
      • Weber's Law and Its Valid Scope
        • Weber's law: to become aware of a change, the stimulus must be increased by a fixed fraction of itself.
        • Valid scope: it determines only when an increase of stimulus produces a change in sensation, not its amount.
        • Minimum threshold: the least perceptible increase is a definite but non-constant function of the stimulus.
        • Real problem: the transition from threshold relation to a psychophysical equation is the whole of psychophysics.
        • Fechner's ambition: to measure sensation itself by defining equality and addition for psychic states.
      • The Artifices of Transition
        • First artifice: treat consciousness of an increased stimulus as an increase of sensation, ΔS.
        • Second artifice: assume all minimum perceptible increments ΔS are equal quantities.
        • Third artifice: set ΔS = C ΔE/f(E), with C constant, linking sensation difference to stimulus difference.
        • Fourth artifice: replace finite differences ΔS and ΔE by differentials dS and dE.
        • Integration: then yields S = C∫dE/f(E), turning a threshold law into a measured law.
      • Fechner's Method of Minimum Differences
        • Equality problem: two different sensations can be equal only if an identical residuum remains after eliminating their qualitative difference.
        • Physical equality: external objects have a separable extensive aspect; psychic states are only quality.
        • Indirect measurement fails: measuring quality by a physical quantity presupposes quality is a function of that quantity, unproven.
        • Fechner's key move: all minimum differences are identical as minima, and this common character defines equality.
        • Addition follows: every sensation is a sum of the minimum differences between zero and itself.
      • Critique: Sensation Is Not a Sum
        • Transition not a reality: only S and S′ exist; the transition from one to the other is not an added term.
        • ΔS by convention: naming the transition makes it first a reality and then a quantity.
        • No interval: simple states have no separable interval, so their succession is not an arithmetical difference.
        • Consciousness's testimony: the difference between two shades is qualitative, like shades of the rainbow, not magnitude.
        • Tannery's verdict: calling a sensation a sum of differential sensations is legitimate but arbitrary.
      • Delbœuf and the Vicious Circle
        • Delbœuf's method: simultaneous contrast between shades of grey appears to give equal quantitative differences directly.
        • Why it persuades: continuous causal change and past experience fuse contrast with arithmetical difference.
        • Common-sense origin: psychophysics pushes to its extreme the habit of objectifying subjective states through their causes.
        • Vicious circle: psychophysics's postulate demands experimental verification, but verification depends on granting the postulate.
        • No contact: nothing joins unextended quality to extended quantity except a conventional assimilation.
      • Intensity's Double Aspect
        • Representative states: intensity is an acquired perception estimating the magnitude of the external cause.
        • Affective states: intensity is a confused perception of the number of simple psychic phenomena involved.
        • Two intermingled streams: representative states are usually affective, so intensity joins external magnitude with inner multiplicity.
        • Inevitable question: if intensity is a magnitude, asking “by how much” is natural; psychophysics cannot be waved away.
        • Way forward: examine inner multiplicity and pure duration without space to expose the problem of freedom.
  • The Multiplicity of Conscious States
    • Number, Space, and Conscious Multiplicity (The Multiplicity of Conscious States · I)
      • Number as a Collection of Identical Units
        • Definition: number is a collection of units, a synthesis of the one and the many.
        • Identity: counted units must be treated as identical, neglecting individual differences.
        • Distinctness: units must differ at least by position in space, or they merge into one.
        • Counting objects: counting material objects means thinking them all together in space.
      • The Spatial Intuition Behind Number
        • Counting in time: we seem to count in duration, but addition needs terms that persist and wait.
        • Spatial localization: each counted moment is fixed at a point in space; pure duration cannot hold a sum.
        • Mental image: every clear idea of number implies a visual image in space; abstract number is mere symbol.
        • Traces in space: vanished moments leave lasting traces that make addition possible.
      • Unity, Multiplicity, and Objectified Units
        • Two unities: number is a simple act of mind; its units are provisional, divisible objects.
        • Objectification: putting a unit aside to pass to the next makes it a thing, hence a multiplicity.
        • Divisibility: arithmetic splits units without limit, revealing them as extended rather than pure acts.
        • Subjective and objective: the subjective is fully known; the objective is indefinitely analyzable in an undivided image.
      • Number in Formation and Number Once Formed
        • Discontinuous construction: building a number proceeds by jerks through provisionally indivisible units.
        • Finished continuity: once formed, points become lines, divisions blur, and the whole appears continuous.
        • Unlimited subdivision: a finished number can be split arbitrarily because it is spatial extension.
      • Two Kinds of Multiplicity
        • Material multiplicity: objects are counted directly in space, without symbolic representation.
        • Conscious multiplicity: psychic states are not numerical except through symbols requiring space.
        • Bell strokes: one can gather a qualitative rhythm or explicitly separate sounds in ideal space.
        • Deep consciousness: sensations and feelings form a confused multiplicity that only analysis distinguishes.
      • The Impenetrability of Matter
        • Logical necessity: impenetrability is a logical demand, not a quality known by the senses.
        • Impossible image: the mind cannot picture two bodies in one place; division continues indefinitely.
    • Space, Number, and Pure Duration (The Multiplicity of Conscious States · II)
      • Number and Impenetrability
        • Impenetrability: logical, not physical; the contrary assertion implies a contradiction.
        • Number: the idea of two or more objects already involves two different positions in space.
        • Counting conscious states: requires representing them symbolically as homogeneous, separate units.
        • Impenetrability of matter: states a property of number rather than of matter.
      • Homogeneous Time and Inner Perception
        • Homogeneous time: a medium where conscious states form a discrete series, as in space.
        • Symbolic representation: projecting psychic states into space gives them a new form in reflective consciousness.
        • Intensity analogy: representative sensation is pure quality, but through extensity becomes quantity.
        • True duration: unlike counted time, is not a discrete multiplicity.
      • Space: Kantian and Empirical Views
        • Kantian space: exists independently of its contents as an a priori form of sensibility.
        • Empiricists: treat sensations as inextensive and still need mental synthesis to produce extensity.
        • Extensity from coexistence: requires an act of mind, much like Kant’s form of sensibility.
        • Space defined: an empty homogeneous medium enabling the distinction of identical simultaneous sensations.
      • The Homogeneous Medium and Animal Perception
        • Space without quality: a principle of differentiation other than qualitative difference.
        • Local signs theory: qualitative differences are interpreted as positions, presupposing homogeneous space.
        • Animal orientation: directions may appear as qualitative shades, not geometrical space.
        • Human faculty: conceiving a homogeneous empty medium makes counting, abstraction, and perhaps speech possible.
      • Pure Duration and the Ghost of Space
        • Pure duration: succession as the ego lets itself live, with states permeating one another.
        • Musical phrase: notes are perceived in one another; altering one changes the whole qualitatively.
        • Succession without distinction: mutual penetration and organization, not points set side by side.
        • Reducing extensity to succession: vicious circle, resting on a superficial idea of time.
        • Projected time: expressing duration in extensity turns succession into a line or chain.
        • Homogeneous time: not a second form of the homogeneous, but the ghost of space haunting reflective consciousness.
    • Duration, Space, and Motion (The Multiplicity of Conscious States · III)
      • Succession Implies Space
        • Succession: order among terms requires distinguishing and comparing places, so succession is projected into space.
        • Reversibility: a reversible or ordered series in duration already presupposes space and cannot define it.
        • Line symbol: representing succession as a line imports three-dimensional space, since perceiving a line requires standing outside it.
        • Conscious point A: if unaware of space, its states melt dynamically into one another, like notes of a tune.
      • Pure Duration Is Qualitative
        • Pure duration: a succession of qualitative changes that melt into and permeate one another, without precise outlines or number.
        • Homogeneity: attributing the least homogeneity to duration surreptitiously introduces space.
        • Measuring time: duration cannot be measured unless symbolically represented in space.
        • Sixty oscillations: pictured at once as points on a line, no succession; one by one, no duration; true duration is interpenetration of images.
        • Pendulum and sleep: sounds act by the rhythmic organization of the whole, not by their quantity.
      • Clock Time and Simultaneity
        • Measuring time: we count simultaneities, not duration; the clock dial gives only positions, with no past preserved.
        • Endosmosis: exchange between inner succession without externality and outer externality without succession creates homogeneous time.
        • Fourth dimension: consciousness preserves oscillations in memory and sets them in series, making homogeneous time an auxiliary space.
        • Intersection: simultaneity is the intersection of time and space, linking real duration to real space.
      • Motion: Act vs Space Traversed
        • Two elements: space traversed is homogeneous and divisible; the act of traversing is indivisible and real only for consciousness.
        • Mental synthesis: motion as passage from point to point is a psychic, unextended process synthesizing successive positions.
        • Qualitative unity: the synthesis resembles a melody, not fresh spatial juxtaposition, which would lead to infinite regress.
        • Shooting star: intuition separates the line of fire from the absolutely indivisible sensation of mobility.
      • Zeno's Paradoxes Resolved
        • Eleatic error: confusing motion with infinitely divisible space traversed makes the interval appear uncrossable.
        • Achilles' steps: each step is a simple indivisible act; after a given number of acts, Achilles passes the tortoise.
        • Two tortoises: Zeno reconstructs Achilles' movement with the tortoise's kind of step, ignoring that acts are indivisible and spaces add differently.
        • Immediate intuition: motion lives within duration and duration outside space; no metaphysical limit to divisibility is needed.
    • Science, Duration, and Qualitative Multiplicity (The Multiplicity of Conscious States · IV)
      • Science Eliminates Duration and Mobility
        • Scientific method: science must eliminate duration from time and mobility from motion to deal with them.
        • Defining equal durations: two intervals are equal when identical bodies traverse equal spaces under identical conditions.
        • Measured simultaneities: mechanics records coincidences of external changes with psychic states, not lived intervals.
        • Accelerated universe: doubling all motions would leave formulas unchanged; only consciousness feels the qualitative change.
      • Velocity Is a Spatial Construct
        • Uniform motion: defined by equal spatial intervals correlated with a repeated physical phenomenon.
        • Variable velocity: derived as a limit of uniform motions over shrinking spatial intervals around a point.
        • Motion reduced to immobility: mechanics retains only traversed space and simultaneous positions, never mobility itself.
        • Astronomer's trick: prediction compresses centuries of simultaneities into seconds by ignoring lived intervals.
      • Equations Cannot Express Becoming
        • Algebra's limit: equations express something already finished, not duration or motion as unceasing process.
        • Differentials: even infinitesimal intervals are approached from their extremities; the interval itself remains outside.
        • Duration's nature: heterogeneous, continuous, with no identical external moments; motion is a mental synthesis, not a line.
      • Two Kinds of Multiplicity
        • Qualitative multiplicity: conscious states permeate and organize one another; number exists only potentially.
        • Quantitative multiplicity: distinct terms are counted by being externalized and set out in homogeneous space.
        • Space alone homogeneous: outside consciousness there are only simultaneities; succession requires comparing present with past.
        • Language spatializes: saying "several" conscious states isolates them, betraying the habit of setting time in space.
      • Counting and Symbolic Time
        • Counting has two sides: identical units require spatial juxtaposition, yet each added unit alters the whole's rhythm.
        • Quality of quantity: interpenetration and qualitative progress make addition possible; numbers carry emotional equivalents.
        • Symbolic substitution: repeated external phenomena, like hammer blows or motion, project duration into homogeneous time.
      • Duration Felt in the Deep Self
        • Surface and depth: superficial states are externally arrayed; deep states interpenetrate, yet both belong to one person.
        • Dreams: relaxing the surface lets duration return to quality, felt rather than mathematically measured.
        • Clock-striking example: we can retrospectively count unheard strokes without having measured them consciously.
    • Two Multiplicities of Conscious Life (The Multiplicity of Conscious States · V)
      • Duration as Quality
        • Four strokes heard: consciousness grasps a musical phrase, a qualitative total, not a sum of units
        • Qualitative multiplicity: successive moments permeate one another, forming an organic whole
        • Two durations: true heterogeneous duration vs. its extensive symbol in homogeneous space
        • Number perceived as quality: counting is retrospective, symbolic, spatialized by imagination
      • Two Selves
        • Shadow self: homogeneous duration and well-defined states project the self into space
        • Fundamental self: states melt into one another; succeeding means interpenetrating
        • Social preference: language and social life favor the refracted, breakable self
        • Recovery requires effort: isolate fluid inner states from images solidified in space
      • Language Solidifies Sensations
        • Town walk: familiar objects borrow our conscious life; impression changes yet seems identical
        • Perception vs. recognition: if impressions were identical, perceiving and recognizing would collapse
        • Words fix feelings: language equates the ever-becoming feeling with its permanent object
        • Sensations not identical: repetition alters every sensation; "tastes" are names for processes
        • Word overwhelms impression: the commonplace word covers the fugitive individual sensation
      • Analysis Distorts Feelings
        • Deep feelings: violent love or melancholy is a thousand interpenetrating elements without outlines
        • Isolation kills: setting elements in time-as-space leaves colorless, namable, lifeless states
        • Feelings live in duration: a feeling develops because its moments permeate one another
        • Novelist's shadow: he shows interpenetration beneath conventional logic, yet still expresses it in words
      • Deep and Surface Ideas
        • Deep beliefs: passionately held ideas match the colour of all our other ideas; reasons are afterthoughts
        • Real idea fills the self: a cell in an organism, affected by the whole state of the self
        • Surface ideas: dead leaves on a pond — ready-made, unassimilated, external, classifiable
        • Associationism applies only to surface: contiguity and logic govern lifeless ideas, not living ones
        • Dreams hint at blending: waking concepts interweave more strangely than dream images
      • The Social Self
        • Second self obscures the first: social life makes states into objects, separated from us and each other
        • Same self throughout: attention can make distinct states melt like snowflakes under a finger
        • Superficial psychology: safe for statics, describes what has taken place; fails on dynamics
        • Contradictions dissolve: causality, freedom, personality problems vanish when we return to the concrete self
  • The Organization of Conscious States
    • Mechanism, Determinism, and Free Will (The Organization of Conscious States · I)
      • Mechanism vs. Dynamism
        • Dynamism: starts from voluntary activity given by consciousness, making facts more real than laws.
        • Mechanism: starts from necessary laws, treating the law as reality and the fact as their meeting point.
        • Simplicity disputed: mechanism equates simple with predictable; dynamism seeks real relationships among notions.
        • Spontaneity is simpler than inertia: inertia is definable only through activity; spontaneity is self-sufficient.
        • Direct knowledge: each of us immediately knows free spontaneity, without needing the notion of inertia.
        • A priori conflict: opposing views of activity flow from how the concrete and abstract, facts and laws, are related.
      • Two Forms of Determinism
        • Physical determinism: actions are necessitated by conservation of energy and molecular mechanics.
        • Psychological determinism: actions are necessitated by feelings, ideas, and the preceding conscious series.
        • Reduction: physical determinism is reducible to psychological; all determinism rests on a psychological hypothesis.
        • Shared flaw: both forms rest on an inaccurate conception of the multiplicity of conscious states or duration.
        • Result: a self emerges whose activity cannot be compared to that of any other force.
      • Physical Determinism Stated and Criticized
        • Molecular picture: the universe becomes a heap of molecules and atoms in unceasing elementary movements.
        • Brain mechanism: sensations, feelings, and ideas are mechanical resultants of external shocks and atomic motions.
        • Laplacian ideal: a mathematician knowing all atomic positions and motions could predict every action with certainty.
        • Parallelism unproven: strict cerebral-psychic correspondence is verified only for a few will-independent cases.
        • Leibniz and Spinoza: accepted parallelism through preestablished harmony or double-language expression, not mechanical causation.
        • Images fail: consciousness as a phosphorescent trail or silent keyboard does not prove psychic fact is fatally determined.
      • Conservation of Energy and Duration
        • No universal a priori law: science long worked without a universal conservation principle; Leibniz's vis viva admitted exceptions.
        • Non-contradiction only: what is given is given; experience decides what persists and which systems can be calculated.
        • Possible new energy: physiological phenomena might reveal an energy that rebels against calculation.
        • Reversible systems: conservation applies only where points can return to former positions; time cannot bite into inert matter.
        • Duration as cause: in life, putting things back is absurd; conscious states resist turning backwards.
      • Physical Determinism Presupposes Psychological Determinism
        • Determination ≠ necessity: common sense believes in free will even when motives explain actions.
        • Associationist determinism: holds conscious states absolutely determined by one another, appealing to consciousness without scientific rigour.
        • Convenient alliance: psychological determinism borrows geometrical character from physical mechanism; mechanism spreads over everything.
        • Epiphenomenon: if molecular movement can create sensation from zero, consciousness could in turn create or redirect movement.
        • Limited freedom: even if energy law determined movements, inner life might remain free but outward action would look automatic.
        • Disguise: physical determinism is psychological determinism seeking to verify itself through the sciences of nature.
    • Duration, Associationism, and the Self (The Organization of Conscious States · II)
      • Duration, Past, and Physical Conservation
        • Prolonged sensation: by lasting, a feeling is altered and swollen by its whole past; it never stays the same.
        • Past as reality: the material point remains in an eternal present; conscious beings store duration and may gain by it.
        • Free will hypothesis: a conscious force storing duration may escape the conservation of energy.
        • Conservation of energy: making it a universal law rests on confusing lived duration with abstract time.
        • Physical determinism: so-called physical determinism reduces at bottom to psychological determinism.
      • Associationist Determinism and Its Circularity
        • Associationist premise: psychic states are necessitated by predecessors through simple reasons of association.
        • Qualitative gap: successive conscious states differ in quality, so no a priori deduction of one from another is possible.
        • Explanatory relation vs cause: the series of associations may be an ex post facto attempt to account for a new idea.
        • Conversation example: the same new idea arises via different intervening series, so it is cause, not effect, of its antecedents.
        • Hypnotic suggestion: conscious antecedents are effects; the future act draws them forth rather than being produced by them.
        • Deliberation: we often weigh motives when the mind is already made up, legitimating the will's coup d'état.
      • Language and the Illusion of Distinct States
        • Language's inadequacy: words fix only the objective, impersonal aspect of inner states, missing delicate shades.
        • Opening-the-window example: the same bodily position feels different from inside according to the end contemplated.
        • Rose perfume: childhood memories are breathed in with the scent, not associated with it by the mind.
        • Association is the philosopher's work: the reconstruction is not the concrete mental fact.
        • Symbols vs states: analysis spreads feelings in a homogeneous medium and gives words, not interpenetrating states.
      • The Self as Interpenetration, Not Aggregate
        • Surface vs depth: association by contiguity fits simple impersonal sensations at the surface, not deep states.
        • Deep states fuse: beneath the surface, each state permeates and is tinged with all the others.
        • Self-determination: a deep feeling reflects the whole soul, so being determined by it is being self-determined.
        • Phantom self: if states are impersonal, setting them side by side yields only a shadow of the ego.
        • Free act: when a single state expresses the whole personality, the self alone is its author.
      • Freedom in Degrees and Parasitic Selves
        • Freedom admits degrees: not all conscious states blend; independent growths can float on the self's surface.
        • Parasitic self: unassimilated education forms a secondary self that encroaches on the fundamental one.
        • Hypnotic and passionate states: suggestion, sudden anger, or hereditary vice may act like foreign forces.
        • Assimilation liberates: suggestion becomes persuasion and passion loses fatality when the whole history of the person is reflected in them.
        • True freedom: many live and die without knowing it; education imparted to the whole soul would not curtail it.
    • Free Will Beyond Spatial Symbols (The Organization of Conscious States · III)
      • Free Decision and the Deep Self
        • Free act: expresses the whole soul; the dynamic series tends to the fundamental self.
        • Real freedom: rare, reserved for great crises; ordinary acts obey association.
        • Deep self: bursts through the outer crust when the whole personality vibrates.
        • Sudden resolve: often without visible reason, yet agrees with our entire inner life.
      • Conscious Automatism in Daily Life
        • Conscious automaton: daily acts follow solidified images tied to impressions, without self interference.
        • Habit crust: stable ideas and words cover the concrete self for social life.
        • Associationism: fits only these numerous insignificant actions, substratum of freedom.
        • Resigned freedom: we let advice solidify on the surface; later we see our mistake.
      • Determinism's Mechanical Self
        • Spatial symbolism: treats the ego and contrary feelings as fixed, self-identical objects.
        • Living deliberation: the self changes while experiencing feelings, modifying them continuously.
        • Dynamic series: states permeate and strengthen one another, ending in a free act.
        • Words kill activity: sharply defined terms deprive the self of living dynamism.
      • Freedom and Character
        • Freedom defined: an act springs from the whole personality, like the artist and his work.
        • Character is self: splitting the person into coercer and coerced is artificial.
        • Altering character: daily imperceptible change is free when blended into the self.
        • Paternity test: the act bearing our personality's mark is truly free.
      • The Illusion of Possible Acts
        • Mill's test: consciousness before decision says either course equally possible; determinists deny this.
        • Geometric myth: choice pictured as the self reaching point O with paths OX and OY open.
        • Real process: only the living, developing self exists; X and Y are abstractions.
        • Common postulate: determinists and libertarians both draw the branching figure after the deed.
        • Deed done, not doing: the figure can be traced only once deliberation is finished.
        • Meaningless question: "could I have chosen Y?" assumes time is space and succession simultaneity.
    • Foresight, Freedom, and Spatialized Time (The Organization of Conscious States · IV)
      • The Spatial Symbol and Its Trap
        • Mechanical symbol: deliberation traced as a line is a stereotyped memory, not the dynamic progress.
        • Fundamental error: confusing time with space; the past can be pictured as a line, the passing cannot.
        • Both parties misled: defenders and determinists treat the act as a path that is or is not already traced.
        • Puerile exchange: "the act, once performed, is performed" vs "before performed, not yet performed" leaves question untouched.
        • Freedom's locus: in a shade or quality of the action itself, not in relation to what might have been.
      • The Futility of Predicting a Free Act
        • Probable forecast: judging a friend's likely conduct is reading present character, not binding future.
        • Determinist claim: complete knowledge of all antecedents would make prediction infallibly true.
        • Peter and Paul: to know all conditions is to be actually performing the act, not foreseeing it.
        • Static vs dynamic knowledge: we can imagine another's states or live them; only the latter gives their real intensity.
        • Assimilated lives: if Paul shares Peter's history, he is Peter; nothing remains to foresee.
      • The Two Illusions of Reflective Consciousness
        • Intensity as quality: psychic intensity is a shade, not a mathematical magnitude or exponent.
        • Symbol for progress: reflecting substitutes the finished act and antecedents for the concrete dynamic becoming.
        • Begging the question: we cannot know antecedents' value without knowing the final act they are supposed to predict.
        • Third illusion: all claims to foresee action reduce to asking "Is time space?"
      • Astronomical Prediction vs Lived Duration
        • Science anticipates eclipses: but this is unlike foreseeing a voluntary act.
        • Equations use simultaneities: symbol t marks relations between durations, not lived duration itself.
        • Accelerated universe: doubling all motions leaves equations unchanged; consciousness would feel altered intervals.
        • Why prediction differs: the future of the material universe has no analogy to the future of a conscious being.
    • Conscious Duration and the Causality Fallacy (The Organization of Conscious States · V)
      • Astronomical Time and Real Duration
        • Astronomical time is a number whose units are left unspecified; the astronomer may shorten or lengthen them at will.
        • Foreseeing is seeing: reducing a future interval preserves spatial relations and turns prediction into present perception.
        • Conscious duration cannot be curtailed without impoverishing the states that fill it and altering their quality.
        • Feelings are processes, not things: cutting a moment from them changes their substance, colour, and nature.
      • Why Future Psychic States Cannot Be Foreseen
        • Astronomical prediction resembles recollection of a past state, not anticipation of a future conscious state.
        • Future psychic states must be lived while unfolding; their duration is their very influence.
        • For deep-seated states, there is no perceptible difference between foreseeing, seeing, and acting.
      • Determinism and Non-Repeatable Inner Life
        • The determinist formula “same antecedents, same consequent” fails because deep psychic states never recur.
        • Duration is real for consciousness: the same moment does not occur twice, so identical conditions are impossible.
        • A repeated feeling is a new feeling: calling it by its old name only reflects a similar external cause or outward attitude.
        • Inner causality produces its effect once for all; it cannot resemble physical causality between repeatable phenomena.
      • The Ambiguity of Causality
        • Empiricist causality as regular succession is drawn from observed facts; it cannot be turned against freedom without begging the question.
        • Common-sense causality transforms subjective association into an objective prefiguring of the future in present conditions.
        • Mathematical prefiguring treats the future as virtually contained in present conditions, but only in the realm of pure quantity.
      • Mechanical Physics Dissolves Concrete Reality
        • Mechanism strips matter of colour, heat, resistance, and weight, leaving homogeneous extensity and abstract law.
        • Kelvin’s vortex atoms: motion in a perfectly homogeneous fluid is equivalent to immobility; it is only a relation between relations.
        • Carried to its end, mechanical causality dissolves nature into algebraical smoke and cannot bind future to present without neglecting duration.
    • Causality, Duration, and Freedom (The Organization of Conscious States · VI)
      • Causality as Mathematical Identity
        • Causal relationship: approaches identity as a curve approaches its asymptote
        • Identity principle: only binds present to present, expressing consciousness's self-confidence
        • Causality's necessity impossible: successive moments of real time are not bound together
        • Cartesian physics: attributes regularity to constantly renewed grace of Providence
        • Spinozistic metaphysics: dissolves apparent causality into identity in the absolute
      • Causality as Dynamic Prefiguring
        • Second prefiguring: future action present as possible idea, not realized effect
        • Effort bridges idea and act: progress continuous, act remains stoppable
        • Hylozoism: qualities become inner states spread through extended matter
        • Leibnizian monads: simple perceptions requiring pre-established harmony
        • No necessary determination: dynamic causality implies things endure, like us
      • The Ambiguous Blend
        • Two hypotheses alone safeguard freedom: first makes nature contingent, second frees enduring self
        • Common sense blends them: imagination prefers dynamic, mathematics prefers necessity
        • Corrupted force: conscious free spontaneity returns from external use impregnated with necessity
        • Endosmosis of ideas: dynamic effort and mathematical determination exchange meanings
        • Physics already separates: external causality is purely mathematical; psychology should treat inner causality as purely dynamic
      • Freedom as Indefinable Fact
        • Freedom: relation of concrete self to the act it performs
        • Indefinable because process: analysis transforms process into thing, duration into extensity
        • Positive definitions fail: "might have been otherwise" implies equivalence of duration and spatial symbol
        • Foreseeability and necessity definitions fail: same equivalence leads back to determinism
        • Core question: Can time be represented by space? Yes for time flown, no for time flowing
        • Free act occurs in flowing time: freedom is clearest fact, only problem is translating it into spatial language
  • Conclusion
    • Space, Quality, Duration, and Freedom (Conclusion · I)
      • The Problem of Borrowed Forms
        • Kant's legacy: modern psychology assumes we perceive things through forms borrowed from our own constitution.
        • Bergson's reversal: ask whether inner states are perceived through forms borrowed from the external world.
        • Forms as compromise: forms applicable to things result from a compromise between matter and mind, not pure mental constructions.
        • Three ideas to purify: intensity, duration, voluntary determination—all contaminated by the obsession with space.
      • Intensity Is Quality
        • Intensity: psychic states are pure quality, not quantity or magnitude.
        • Cause in space: quantity lies behind quality; intensity is the qualitative sign of that quantity.
        • No intensive magnitude: "increase" and "decrease" apply to sensations only metaphorically.
        • Psychophysics refuted: if sensation were magnitude, measurement would be possible; since it is not, intensity is quality.
      • Duration Is Qualitative Multiplicity
        • Number's conditions: number requires intuition of homogeneous space and a dynamic process of permeation.
        • Discrete multiplicity: material objects are impenetrable and divisible; conscious states are not.
        • Associationism's error: reconstructing the self by adding distinct states substitutes the symbol for the ego.
        • Inner duration: qualitative multiplicity, organic evolution, pure heterogeneity without distinct qualities.
        • Succession without externality: inner moments succeed and interpenetrate; outer moments are external but do not succeed.
      • Science and Measurable Time
        • Outside us: only simultaneity exists; change is observed only by a consciousness that remembers.
        • Science's abstraction: science retains from duration only simultaneity, from motion only position.
        • Mixed idea of time: measurable time is a compromise—space as homogeneity, duration as succession.
        • Endosmosis: clock pendulum cuts inner interpenetration into distinct fragments, spreading duration lengthwise.
      • Freedom and the Two Selves
        • Space-time confusion: determinism and its opponents both identify time with space or demand space represent time.
        • Causality equivocation: determinists play on two senses of causality, giving duration mutually exclusive forms.
        • Energy principle: cannot apply conservation to conscious moments, which acquire a richer and richer content.
        • Two selves: the fundamental self is free; its spatial, social representation is the objectified projection.
        • Language and society: fixed names objectify states, concealing interpenetration for social convenience.
    • Freedom Through Real Duration (Conclusion · II)
      • Rare Self-Possession and Free Action
        • Deep introspection: grasps inner states as living, becoming, unmeasurable, interpenetrating.
        • Rare moments: we seldom grasp ourselves, hence rarely free.
        • Outer life: we live in space, speak rather than think, are acted rather than act.
        • Free act: recover possession of oneself and return to pure duration.
      • Kant’s Mistake
        • Homogeneous time: Kant confused real duration with its spatial symbol.
        • Recurrence error: same states can recur only if duration is homogeneous; then causality binds and freedom incomprehensible.
        • Noumenal freedom: Kant exiled free self outside time as well as space, beyond knowledge.
        • Kantian strength and weakness: its foundation for phenomena depends on confusing true duration with its symbol.
      • Science and the Phenomenal World
        • Mathematical limits: duration and motion elude mathematics; only simultaneity and immobility remain.
        • Knowability: relations not translatable into simultaneity are scientifically unknowable; freedom would be incomprehensible.
        • Kant's barrier: he gave phenomena to understanding and forbade entry to things-in-themselves.
        • Corrected conception: if duration's moments permeate, self is free cause, knowable absolutely, and phenomena less amenable to math.
      • Symbolic Self and Automatism
        • Homogeneous space: intuition peculiar to man, externalizes concepts, prepares social life and language.
        • Symbolization: living self's qualitative multiplicity replaced by numerical, juxtaposed, word-like states.
        • Automatism: crystallized states and fixed associations let automatism cover over freedom.
        • Associationists and determinists: see only common states, treat time as space, then deny or banish freedom.
      • Freedom Resolved
        • Serious decisions: unique, unrepeatable moments; relation to act cannot be expressed by law.
        • Necessity meaningless: foreseeing or reasoning about contrary action impossible in concrete duration.
        • Illusion source: imperceptible transition from concrete to symbolical duration, from free activity to automatism.
        • Problem misunderstanding: confusion of succession with simultaneity, duration with extensity, quality with quantity.
• Core Conclusion and Practical Takeaways
  • Core Conclusions
    • Reality is duration: immediate consciousness is a continuous, qualitative flow—not a series of separate states.
    • Intensity is quality: psychic states are qualitative shades, not quantities; we only metaphorically call them greater or lesser.
    • Measurable time is spatial: clock time is the ghost of space haunting reflective consciousness, not lived duration.
    • Two selves coexist: a superficial social self of fixed states obscures the fundamental self whose states interpenetrate.
    • Freedom is a fact: the living self's act is free; the problem arises only when we translate it into spatial symbols.
  • Understanding Free Will
    • Free act: springs from the whole personality, like an artist's work, not from one motive among others.
    • Determinism's error: both camps treat the act as a pre-traced path, confusing time with space.
    • Same antecedents impossible: deep psychic states never recur, so the determinist formula has no application.
    • Foresight confusion: predicting a free act would require living it; only surface automatism is predictable.
    • Freedom is indefinable: analysis turns process into thing; the free act is the self expressing itself in flowing duration.
  • Daily Practices
    • Pause before words: avoid naming feelings too quickly; words fix and falsify the fluid inner state.
    • Return to qualitative attention: notice how emotions alter the whole soul rather than measuring their intensity.
    • Let duration be felt: listen to music or watch a melody of inner states without clocking intervals.
    • Recognize the social self: treat conventional opinions and fixed labels as surface cover, not your fundamental self.
    • Decide from the whole self: deliberate after inner reflection, letting the act express your entire history, not one motive.
    • Use art as training: poetry, music, and rhythm suspend conceptual habits and restore interpenetrating perception.
  • Mindset Shifts
    • Question spatial metaphors: resist picturing time as a line, effort as quantity, or feelings as objects.
    • Embrace qualitative multiplicity: inner life is a dynamic interpenetration, not a sum of distinct units.
    • Distinguish recognition from perception: repeated impressions are never identical; each is a new process.
    • Value the deep self: social life favors the shadow self; reclaiming the fundamental self takes effort.
    • See problems as illusions: many philosophical puzzles dissolve when duration is not spatialized.
