Time and Free Will · Henri Bergson
CONCLUSION
It seemed to us that there was good reason to set ourselves the opposite problem and to ask whether the most obvious states of the ego itself, which we believe that we grasp directly, are not mostly perceived through the medium of certain forms borrowed from the external world, which thus gives us back what we have lent it. _A priori_ it seems fairly probable that this is what happens. For, assuming that the forms alluded to, into which we fit matter, come entirely from the mind, it seems difficult to apply them constantly to objects without the latter soon leaving a mark on them: by then using these forms to gain a knowledge of our own person we run the risk of mistaking for the colouring of the self the reflection of the frame in which we place it, i.e. the external world. But one can go further still and assert that forms applicable to things cannot be entirely our own work, that they must result from a compromise between matter and mind, that if we give much to matter we probably receive something from it, and that thus, when we try to grasp ourselves after an excursion into the external world, we no longer have our hands free. [Sidenote: To understand the intensity, duration and voluntary determination of psychic states, we must eliminate the idea of space.]
Now just as, in order to ascertain the real relations of physical phenomena to one another, we abstract whatever obviously clashes with them in our way of perceiving and thinking, so, in order to view the self in its original purity, psychology ought to eliminate or correct certain forms which bear the obvious mark of the external world. What are these forms? When isolated from one another and regarded as so many distinct units, psychic states seem to be more or less _intense._ Next, looked at in their multiplicity, they unfold in time and constitute _duration._ Finally, in their relations to one another, and in so far as a certain unity is preserved throughout their multiplicity, they seem to _determine_ one another. Intensity, duration, voluntary determination, these are the three ideas which had to be clarified by ridding them of all that they owe to the intrusion of the sensible world and, in a word, to the obsession of the idea of space. [Sidenote: Intensity is quality and not quantity or magnitude.]
Examining the first of these ideas, we found that psychic phenomena were in themselves pure quality or qualitative multiplicity, and that, on the other hand, their cause situated in space was quantity. In so far as this quality becomes the sign of the quantity and we suspect the presence of the latter behind the former, we call it intensity. The intensity of a simple state, therefore, is not quantity but its qualitative sign. You will find that it arises from a compromise between pure quality, which is the state of consciousness, and pure quantity, which is necessarily space. Now you give up this compromise without the least scruple when you study external things, since you then leave aside the forces themselves, assuming that they exist, and consider only their measurable and extended effects. Why, then, do you keep to this hybrid concept when you analyse in its turn the state of consciousness? If magnitude, outside you, is never intensive, intensity, within you, is never magnitude. It is through having overlooked this that philosophers have been compelled to distinguish two kinds of quantity, the one extensive, the other intensive, without ever succeeding in explaining what they had in common or how the same words "increase" and "decrease" could be used for things so unlike. In the same way they are responsible for the exaggerations of psychophysics, for as soon as the power of increasing in magnitude is attributed to sensation in any other than a metaphorical sense, we are invited to find out by how much it increases. And, although consciousness does not measure intensive quantity, it does not follow that science may not succeed indirectly in doing so, if it be a magnitude. Hence, either a psychophysical formula is possible or the intensity of a simple psychic state is pure quality.
Here again a compromise comes in. To the simultaneities, which constitute the external world, and, although distinct, succeed one another _for our consciousness,_ we attribute succession _in themselves._ Hence the idea that things _endure_ as we do ourselves and that time may be brought within space. But while our consciousness thus introduces succession into external things, inversely these things themselves externalize the successive moments of our inner duration in relation to one another. The simultaneities of physical phenomena, absolutely distinct in the sense that the one has ceased to be when the other takes place, cut up into portions, which are also distinct and external to one another, an inner life in which succession implies interpenetration, just as the pendulum of a clock cuts up into distinct fragments and spreads out, so to speak, lengthwise, the dynamic and undivided tension of the spring. Thus, by a real process of endosmosis we get the mixed idea of a measurable time, which is space in so far as it is homogeneity, and duration in so far as it is succession, that is to say, at bottom, the contradictory idea of succession in simultaneity. [Sidenote: As science eliminates duration from the outer, philosophy must eliminate space from the inner world.] Now, these two elements, extensity and duration, science tears asunder when it undertakes the close study of external things. For we have pointed out that science retains nothing of duration but simultaneity, and nothing of motion itself position of the moving body, i.e. immobility. A very sharp separation is here made and space gets the best of it.
Therefore the same separation will have to be made again, but this time to the advantage of duration, when inner phenomena are studied,--not inner phenomena once developed, to be sure, or after the discursive reason has separated them and set them out in a homogeneous medium in order to understand them, but inner phenomena in their developing, and in so far as they make up, by their interpenetration, the continuous evolution of a free person. Duration, thus restored to its original purity, will appear as a wholly qualitative multiplicity, an absolute heterogeneity of elements which pass over into one another. [Sidenote: The neglect to separate extensity and duration leads one party to deny freedom and the other to define it.]
Now it is because they have neglected to make this necessary separation that one party has been led to deny freedom and the other to define it, and thereby, involuntarily, to deny it too. They ask in fact whether the act could or could not be foreseen, the whole of its conditions being given; and whether they assert it or deny it, they admit that this totality of conditions could be conceived as given in advance: which amounts, as we have shown, to treating duration as a homogeneous thing and intensities as magnitudes. They will either say that the act is _determined_ by its conditions, without perceiving that they are playing on the double sense of the word causality, and that they are thus giving to duration at the same time two forms which are mutually exclusive. Or else they will appeal to the principle of the conservation of energy, without asking whether this principle is equally applicable to the moments of the external world, which are equivalent to one another, and to the moments of a living and conscious being, which acquire a richer and richer content. In whatever way, in a word, freedom is viewed, it cannot be denied except on condition of identifying time with space; it cannot be defined except on condition of demanding that space should adequately represent time; it cannot be argued about in one sense or the other except on condition of previously confusing succession and simultaneity. All determinism will thus be refuted by experience, but every attempt to define freedom will open the way to determinism.
Hence there are finally two different selves, one of which is, as it were, the external projection of the other, its spatial and, so to speak, social representation. We reach the former by deep introspection, which leads us to grasp our inner states as living things, constantly _becoming,_ as states not amenable to measure, which permeate one another and of which the succession in duration has nothing in common with juxtaposition in homogeneous space. But the moments at which we thus grasp ourselves are rare, and that is just why we are rarely free. The greater part of the time we live outside ourselves, hardly perceiving anything of ourselves but our own ghost, a colourless shadow which pure duration projects into homogeneous space. Hence our life unfolds in space rather than in time; we live for the external world rather than for ourselves; we speak rather than think; we "are acted" rather than act ourselves. To act freely is to recover possession of oneself, and to get back into pure duration. [Sidenote: Kant clung to freedom, but put the self which is free outside both space and time.]
Kant's great mistake was to take time as a homogeneous medium. He did not notice that real duration is made up of moments inside one another, and that when it seems to assume the form of a homogeneous whole, it is because it gets expressed in space. Thus the very distinction which he makes between space and time amounts at bottom to confusing time with space, and the symbolical representation of the ego with the ego itself. He thought that consciousness was incapable of perceiving psychic states otherwise than by juxtaposition, forgetting that a medium in which these states are set side by side and distinguished from one another is of course space, and not duration. He was thereby led to believe that the same states can recur in the depths of consciousness, just as the same physical phenomena are repeated in space; this at least is what he implicitly admitted when he ascribed to the causal relation the same meaning and the same function in the inner as in the outer world. Thus freedom was made into an incomprehensible fact. And yet, owing to his unlimited though unconscious confidence in this inner perception whose scope he tried to restrict, his belief in freedom remained unshakable. He therefore raised it to the sphere of noumena; and as he had confused duration with space, he made this genuine free self, which is indeed outside space, into a self which is supposed to be outside duration too, and therefore out of the reach of our faculty of knowledge. But the truth is that we perceive this self whenever, by a strenuous effort of reflection, we turn our eyes from the shadow which follows us and retire into ourselves. Though we generally live and act outside our own person, in space rather than in duration, and though by this means we give a handle to the law of causality, which binds the same effects to the same causes, we can nevertheless always get back into pure duration, of which the moments are internal and heterogeneous to one another, and in which a cause cannot repeat its effect since it will never repeat itself.
Now, this must not be thought to be a mode of symbolical representation only, for immediate intuition and discursive thought are one in concrete reality, and the very mechanism by which we only meant at first to explain our conduct will end by also controlling it. Our psychic states, separating then from each other, will get solidified; between our ideas, thus crystallized, and our external movements we shall witness permanent associations being formed; and little by little, as our consciousness thus imitates the process by which nervous matter procures reflex actions, automatism will cover over freedom.[10] It is just at this point that the associationists and the determinists come in on the one side, and the Kantians on the other. As they look at only the commonest aspect of our conscious life, they perceive clearly marked states, which can recur in time like physical phenomena, and to which the law of causal determination applies, if we wish, in the same sense as it does to nature. As, on the other hand, the medium in which these psychic states are set side by side exhibits parts external to one another, in which the same facts seem capable of being repeated, they do not hesitate to make time a homogeneous medium and treat it as space.
Henceforth all difference between duration and extensity, succession and simultaneity, is abolished: the only thing left is to turn freedom out of doors, or, if you cannot entirely throw off your traditional respect for it, to escort it with all due ceremony up to the supratemporal domain of "things in themselves," whose mysterious threshold your consciousness cannot cross. But, in our view, there is a third course which might be taken, namely, to carry ourselves back in thought to those moments of our life when we made some serious decision, moments unique of their kind, which will never be repeated--**any more than the past phases in the history of a nation will ever come back again. We should see that if these past states cannot be adequately expressed in words or artificially reconstructed by a juxtaposition of simpler states, it is because in their dynamic unity and wholly qualitative multiplicity they are phases of our real and concrete duration, a heterogeneous duration and a living one. We should see that, if our action was pronounced by us to be free, it is because the relation of this action to the state from which it issued could not be expressed by a law, this psychic state being unique of its kind and unable ever to occur again.
We should see, finally, that the very idea of necessary determination here loses every shred of meaning, that there cannot be any question either of foreseeing the act before it is performed or of reasoning about the possibility of the contrary action once the deed is done, for to have all the conditions given is, in concrete duration, to place oneself at the very moment of the act and not to foresee it. But we should also understand the illusion which makes the one party think that they are compelled to deny freedom, and the others that they must define it. It is because the transition is made by imperceptible steps from concrete duration, whose elements permeate one another, to symbolical duration, whose moments are set side by side, and consequently from free activity to conscious automatism. It is because, although we are free whenever we are willing to get back into ourselves, it seldom happens that we are willing. It is because, finally, even in the cases where the action is freely performed, we cannot reason about it without setting out its conditions externally to one another, therefore in space and no longer in pure duration. The problem of freedom has thus sprung from a misunderstanding: it has been to the moderns what the paradoxes of the Eleatics were to the ancients, and, like these paradoxes, it has its origin in the illusion through which we confuse succession and simultaneity, duration and extensity, quality and quantity.
