Matter and Memory

Overview

About two hundred and sixty pages, published in 1896, Bergson’s second book and, by most accounts including his own, his most technically demanding and philosophically ambitious. Its subtitle, an essay on the relation of body and mind, states its aim directly: to make progress on the classical mind-body problem by rejecting the terms in which both dominant traditional answers, materialism, which explains mind as ultimately reducible to physical brain processes, and idealism, which treats matter as ultimately reducible to mental representation, have posed the question.

Bergson’s route into the problem is unusual and deliberately so. Rather than starting from an already-assumed mind on one side and an already-assumed physical world on the other, and then asking how the two relate, he begins from a more neutral starting category he calls images, things given to us in perception that are more than what idealists call mere representations, dependent entirely on a perceiving mind, but less than what strict materialists call independently existing things, entirely separate from and unrelated to any relation to perception. This starting point is meant to dissolve, rather than simply answer, the traditional problem, by refusing the sharp initial division between wholly mental and wholly material that generates the problem in its classical form.

The argument

Images, and the redefinition of matter and perception. Bergson defines matter as an aggregate of images, existing independently of any particular perception of it, images that act and react on one another according to fixed laws, in what he calls, provocatively, a picture that exists without anyone looking at it. Perception then becomes, on this framework, not the creation of a new, purely mental representation added on top of an independently existing physical world, but a genuine selection made from within that already-existing field of images, a narrowing down of the total field to whatever portion is relevant to a particular body’s possible action.

This has a striking consequence Bergson develops at length: perceiving is not, on his account, a matter of adding something, a mental picture, to a physical world that has none; it is a matter of subtracting, isolating from the total field of images just those aspects relevant to what a given body, with its particular needs and capacities for action, might actually do. A living body with a nervous system does not generate representation where none existed; it introduces a genuine gap, a zone of indetermination, into the otherwise continuous, mechanically determined interaction of images, and perception is what fills, or rather what selectively narrows, that gap.

The body as a center of action, not a container of thought. This reframing lets Bergson make his central claim about the brain and nervous system: rather than functioning as an organ that stores or produces mental representations, receiving sensory input and generating thoughts and images internally the way a camera produces photographs, the brain and nervous system function as instruments of selection and delay, receiving a vast field of possible stimuli and narrowing it down to whatever is relevant to the body’s own possible movements and actions, introducing a pause, a moment of hesitation, between stimulus and automatic response that is precisely what makes deliberate, chosen action, rather than pure reflex, possible.

Two kinds of memory. The book’s second major argument turns to memory, and Bergson draws a sharp distinction between two fundamentally different kinds that he insists are too often confused with one another. Habit memory is a mechanism built into the body itself through repetition, learned once through practice and thereafter expressed automatically as action rather than as a recalled image, the way a child memorizing a lesson repeats it, or the way a trained skill, once acquired, operates without conscious recall of each individual instance of practice that built it.

Pure memory, by contrast, is the accumulating, essentially spiritual record of unique, unrepeatable past events, each one preserved exactly as it happened, in its own particular, unrepeatable place in the flow of duration, surviving independently of any specific bodily mechanism and recalled, when it is recalled, rather than reconstructed or manufactured anew. This pure memory, on Bergson’s account, is not stored in the brain at all; the brain’s role with respect to it is not storage but selective retrieval, choosing, again with a view to present action, which portion of an essentially intact and continuously accumulating past becomes relevant and therefore consciously recalled at any given moment.

Evidence from aphasia. Bergson grounds this distinction in an extended and, for its time, genuinely sophisticated engagement with contemporary clinical evidence about aphasia, disorders of language following brain damage. He argues at length that the pattern of these disorders, in which patients often lose the capacity to produce or recognize particular words or classes of words, without thereby losing the underlying memories or concepts those words would have expressed, supports his general claim that the brain functions to select and enable the expression of memory in action rather than to store memories as such. Damage to specific brain regions, on this reading, impairs specific mechanisms of motor expression and selection, the sensorimotor apparatus that lets a memory find its way into actual speech or action, without necessarily destroying the underlying pure memory itself, which Bergson argues survives, in principle, independently of any particular bodily mechanism for its retrieval.

Duration and the reality of the past. Underlying both arguments is Bergson’s broader conception of duration, developed at greater length in Time and Free Will, according to which the past does not simply cease to exist once it has occurred but continues to exist, accumulating and interpenetrating with the present in a continuous, indivisible flow. Pure memory, on this account, is not a faint copy or trace of a past that has otherwise vanished; it is the continued survival, in principle undiminished, of that past itself, which is why Bergson can argue that memory in its pure form is not, strictly speaking, stored anywhere physical at all, but persists as part of the ongoing reality of duration.

How to read it

Read the first chapter with real patience; it lays out the theory of images and the redefinition of perception as selection rather than construction, and the book’s entire later argument, particularly the treatment of memory and aphasia, depends on having genuinely absorbed this initial, unusual framework rather than reading past it quickly to get to the more concrete material on memory.

Keep the two kinds of memory sharply distinguished as you read the later chapters, since much of Bergson’s argument, particularly the treatment of clinical evidence, depends on this distinction doing real work, habit memory as a bodily mechanism producing action, pure memory as an accumulating, essentially non-physical record of the unrepeatable past.

Notice how directly Bergson engages with the actual neurological and psychological science of his own period, particularly research on aphasia, rather than arguing in a purely abstract, speculative register. This engagement was genuinely current for 1896, and evaluating how well his specific interpretations of that evidence hold up against later neuroscience is a legitimate and productive way to test his broader philosophical claims.

Read this book as Bergson’s own attempt to dissolve, rather than solve on either side’s terms, the traditional mind-body problem, and ask specifically whether starting from images, rather than from an already-assumed mind or an already-assumed independent matter, genuinely avoids the problem’s classical difficulties or merely relocates them under new vocabulary.

Read Time and Free Will before this book if you have not already; Matter and Memory presupposes the account of duration developed there, and understanding what duration means for Bergson before tackling his more technical claims about pure memory’s independent survival makes this considerably harder book more tractable.

Questions it raises

• Does Bergson’s category of images successfully occupy a genuine middle ground between idealist representation and materialist matter, or does it end up collapsing, on closer inspection, into one or the other?
• Is perception really best understood as selection from an already-existing field, subtracting rather than adding, or does this framework struggle to account for genuinely novel perceptual content that was not somehow already present in the field being selected from?
• Does the evidence from aphasia actually support Bergson’s claim that the brain selects and enables rather than stores memory, or is this interpretation now superseded by later neuroscience showing more direct storage functions?
• If pure memory survives independently of any bodily mechanism, where, if anywhere, does it actually exist, and does this claim commit Bergson to something like a non-physical soul despite his stated aim of avoiding traditional dualism?
• What is gained by distinguishing habit memory so sharply from pure memory? Does ordinary remembering actually divide this cleanly, or do the two kinds constantly blend into one another in practice?
• Bergson wants to avoid both materialism and idealism. Does his actual account of images, perception and memory succeed in charting a genuinely third path, or does it ultimately lean toward one side despite its stated neutrality?
