"The apparent discontinuity of psychological life is due, then, to the fact that our attention is concentrated on it in a series of discontinuous acts; where there is only a gentle slope, we think we see, when we follow the broken line of our attention, the steps of a staircase. It is true that our psychological life is full of surprises.
A thousand incidents arise which seem to contrast with what precedes them, and not to be connected with what follows. But the gap in their appearances stands out against the continuous background on which they are represented, and to which they owe the very intervals that separate them; they are the drumbeats which break into the symphony at intervals.
Our attention is fixed upon them because they interest it more, but each of them proceeds from the fluid ma.s.s of our entire psychological existence. Each of them is only the brightest point in a moving zone which understands all that we feel, think, wish; in fact, all that we are at a given moment. It is this zone which really const.i.tutes our state. But we may observe that states defined in this way are not distinct elements. They are an endless stream of mutual continuity."
And do not think that perhaps such a description represents only or princ.i.p.ally our life of feeling. Reason and thought share the same characteristic, as soon as we penetrate their living depth, whether it be a question of creative invention or of those primordial judgments which direct our activity. If they evidence greater stability, it is in permanence of direction, because our past remains present to us.
For we are endowed with memory, and that perhaps is, on the whole, our most profound characteristic. It is by memory we enlarge ourselves and draw continually upon the wealth of our treasuries. Hence comes the completely original nature of the change which const.i.tutes us. But it is here that we must shake off familiar representations! Common-sense cannot think in terms of movement. It forges a static conception of it, and destroys it by arresting it under pretext of seeing it better. To define movement as a series of positions, with a generating law, with a time-table or correspondence sheet between places and times, is surely a ready-made presentation. Are we not confusing the trajectory and its performance, the points traversed and the traversing of the points, the result of the genesis of the result; in short, the quant.i.tative distance over which the flight extends, and the qualitative flight which puts this distance behind it? In this way the very mobility which is the essence of movement vanishes. There is the same common mistake about time. a.n.a.lytic and synthetic thought can see in time only a string of coincidences, each of them instantaneous, a logical series of relations.
It imagines the whole of it to be a graduated slide-rule, in which the luminous point called the present is the geometrical index.
Thus it gives form to time in s.p.a.ce, "a kind of fourth dimension,"
("Essay on the Immediate Data".) or at least it reduces it to nothing more than an abstract scheme of succession, "a stream without bottom or sides, flowing without determinable strength, in an indefinable direction." ("Introduction to Metaphysics".) It requires time to be h.o.m.ogeneous, and every h.o.m.ogeneous medium is s.p.a.ce, "for as h.o.m.ogeneity consists here in the absence of any quality, it is not clear how two forms of h.o.m.ogeneity could be distinguished one from the other." ("Essay on the Immediate Data", page 74.)
Quite different appears real duration, the duration which is lived.
It is pure heterogeneity. It contains a thousand different degrees of tension or relaxation, and its rhythm varies without end. The magic silence of calm nights or the wild disorder of a tempest, the still joy of ecstasy or the tumult of pa.s.sion unchained, a steep climb towards a difficult truth or a gentle descent from a luminous principle to consequences which easily follow, a moral crisis or a shooting pain, call up intuitions admitting no comparison with one another. We have here no series of moments, but prolonged and interpenetrating phases; their sequence is not a subst.i.tution of one point for another, but rather resembles a musical resolution of harmony into harmony. And of this ever-new melody which const.i.tutes our inner life every moment contains a resonance or an echo of past moments. "What are we really, what is our character, except the condensation of the history which we have lived since our birth, even before our birth, since we bring with us our prenatal dispositions? Without doubt we think only with a small part of our past; but it is with our complete past, including our original bias of soul, that we desire, wish, and act." ("Creative Evolution", pages 5-6.) This is what makes our duration irreversible, and its novelty perpetual, for each of the states through which it pa.s.ses envelops the recollection of all past states. And thus we see, in the end, how, for a being endowed with memory, "existence consists in change, change in ripening, ripening in endless self-creation."
("Creative Evolution", page 8.)
With this formula we face the capital problem in which psychology and metaphysics meet, that of liberty. The solution given by Mr Bergson marks one of the culminating points of his philosophy. It is from this summit that he finds light thrown on the riddle of inner being. And it is the centre where all the lines of his research converge.
What is liberty? What must we understand by this word? Beware of the answer you are going to give. Every definition, in the strict sense of the term, will imply the determinist thesis in advance, since, under pain of going round in a circle, it will be bound to express liberty as a function of what it is not. Either psychological liberty is an illusive appearance, or, if it is real, we can only grasp it by intuition, not by a.n.a.lysis, in the light of an immediate feeling. For a reality is verified, not constructed; and we are now or never in one of those situations where the philosopher"s task is to create some new concept, instead of abiding by a combination of previous elements.
Man is free, says common-sense, in so far as his action depends only on himself. "We are free," says Mr Bergson, ("Essay on the Immediate Data of Consciousness", page 131.) "when our acts proceed from our entire personality, when they express it, when they exhibit that indefinable resemblance to it which we find occasionally between the artist and his work." That is all we need seek; two conceptions which are equivalent to each other, two concordant formulae. It is true that this amounts to determining the free act by its very originality, in the etymological sense of the word: which is at bottom only another way of declaring it incommensurable with every concept, and reluctant to be confined by any definition. But, after all, is not that the only true immediate fact?
That our spiritual life is genuine action, capable of independence, initiative, and irreducible novelty, not mere result produced from outside, not simple extension of external mechanism, that it is so much ours as to const.i.tute every moment, for him who can see, an essentially incomparable and new invention, is exactly what represents for us the name of liberty. Understood thus, and decidedly it is like this that we must understand it, liberty is a profound thing: we seek it only in those moments of high and solemn choice which come into our life, not in the petty familiar actions which their very insignificance submits to all surrounding influences, to every wandering breeze. Liberty is rare; many live and die and have never known it. Liberty is a thing which contains an infinite number of degrees and shades; it is measured by our capacity for the inner life. Liberty is a thing which goes on in us unceasingly: our liberty is potential rather than actual. And lastly, it is a thing of duration, not of s.p.a.ce and number, not the work of moments or decrees. The free act is the act which has been long in preparing, the act which is heavy with our whole history, and falls like a ripe fruit from our past life.
But how are we to establish positive verification of these views? How are we to do away with the danger of illusion? The proof will in this case result from a criticism of adverse theories, along with direct observation of psychological reality freed from the deceptive forms which warp the common perception of it. And it will here be an easy task to resume Mr Bergson"s reasoning in a few words.
The first obstacle which confronts affirmation of our liberty comes from physical determinism. Positive science, we are told, presents the universe to us as an immense h.o.m.ogeneous transformation, maintaining an exact equivalence between departure and arrival. How can we possibly have after that the genuine creation which we require in the act we call free?
The answer is that the universality of the mechanism is at bottom only a hypothesis which is still awaiting demonstration. On the one hand it includes the parallelist conception which we have recognised as effete.
And on the other it is plain that it is not self-sufficient. At least it requires that somewhere or other there should be a principle of position giving once for all what will afterwards be maintained. In actual fact, the course of phenomena displays three tendencies: a tendency to conservation, beyond question; but also a tendency to collapse, as in the diminution of energy; and a tendency to progress, as in biological evolution. To make conservation the sole law of matter implies an arbitrary decree, denoting only those aspects of reality which will count for anything. By what right do we thus exclude, with vital effort, even the feeling of liberty which in us is so vigorous?
We might say, it is true, that our spiritual life, if it is not a simple extension of external mechanism, yet proceeds according to an internal mechanism equally severe, but of a different order. This would bring us to the hypothesis of a kind of psychological mechanism; and in many respects this seems to be the common-sense hypothesis. I need not dwell upon it, after the numerous criticisms already made. Inner reality--which does not admit number--is not a sequence of distinct terms, allowing a disconnected waste of absolute causality.
And the mechanism of which we dream has no true sense--for, after all, it has a sense--except in relation to the superficial phenomena which take place in our dead rind, in relation to the automaton which we are in daily life. I am ready to admit that it explains our common actions, but here it is our profound consciousness which is in question, not the play of our materialised habits.
Without insisting, then, too strongly on this mongrel conception, let us pa.s.s to the direct examination of inner psychological reality.
Everything is ready for the conclusion. Our duration, which is continually acc.u.mulating itself, and always introducing some irreducible new factor, prevents any kind of state, even if superficially identical, from repeating itself in depth. "We shall never again have the soul we had this evening." Each of our moments remains essentially unique. It is something new added to the surviving past; not only new, but unable to be foreseen.
For how can we speak of foresight which is not simple conjecture, how can we conceive an absolute extrinsic determination, when the act in birth only makes one with the finished sum of its conditions, when these conditions are complete only on the threshold of the action beginning, including the fresh and irreducible contribution added by its very date in our history? We can only explain afterwards, we can only foresee when it is too late, in retrospect, when the accomplished action has fallen into the plan of matter.
Thus our inner life is a work of enduring creation: of phases which mature slowly, and conclude at long intervals the decisive moments of emanc.i.p.ating discovery. Undoubtedly matter is there, under the forms of habit, threatening us with automatism, seeking at every moment to devour us, stealing a march on us whenever we forget. But matter represents in us only the waste of existence, the mortal fall of weakened reality, the swoon of the creative action falling back inert; while the depths of our being still pulse with the liberty which, in its true function, employs mechanism itself only as a means of action.
Now, does not this conception make a singular exception of us in nature, an empire within an empire? That is the question we have yet to investigate.
II.
We have just attempted to grasp what being is in ourselves; and we have found that it is becoming, progress, and growth, that it is a creative process which never ceases to labour incessantly; in a word, that it is duration. Must we come to the same conclusion about external being, about existence in general?
Let us consider that external reality which is nearest us, our body. It is known to us both externally by our perceptions and internally by our affections. It is then a privileged case for our inquiry. In addition, and by a.n.a.logy, we shall at the same time study the other living bodies which everyday induction shows us to be more or less like our own. What are the distinctive characteristics of these new realities? Each of them possesses a genuine individuality to a far greater degree than inorganic objects; whilst the latter are hardly limited at all except in relation to the needs of the former, and so do not const.i.tute beings in themselves, the former evidence a powerful internal unity which is only further emphasised by their prodigious complication, and form wholes with are naturally complete. These wholes are not collections of juxtaposed parts: they are organisms; that is to say, systems of connected functions, in which each detail implies the whole, and where the various elements interpenetrate. These organisms change and modify continually; we say of them not only that they are, but that they live; and their life is mutability itself, a flight, a perpetual flux. This uninterrupted flight cannot in any way be compared to a geometrical movement; it is a rhythmic succession of phases, each of which contains the resonance of all those which come before; each state lives on in the state following; the life of the body is memory; the living being acc.u.mulates its past, makes a s...o...b..ll of itself, serves as an open register for time, ripens, and grows old. Despite all resemblances, the living body always remains, in some measure, an absolutely original and unique invention, for there are not two specimens exactly alike; and, among inert objects, it appears as the reservoir of indetermination, the centre of spontaneity, contingence, and genuine action, as if in the course of phenomena nothing really new could be produced except by its agency.
Such are the characteristic tendencies of life, such the aspects which it presents to immediate observation. Whether spiritual activity unconsciously presides over biological evolution, or whether it simply prolongs it, we always find here and there the essential features of duration.
But I spoke just now of "individuality." Is it really one of the distinctive marks of life? We know how difficult it is to define it accurately. Nowhere, not even in man, is it fully realised; and there are beings in existence in which it seems a complete illusion, though every part of them reproduces their complete unity.
True, but we are now dealing with biology, in which geometrical precision is inadmissible, where reality is defined not so much by the possession of certain characteristics as by its tendency to accentuate them. It is as a tendency that individuality is more particularly manifested; and if we look at it in this light, no one can deny that it does const.i.tute one of the fundamental tendencies of life. Only the truth is that the tendency to individuality remains always and everywhere counterbalanced, and therefore limited, by an opposing tendency, the tendency to a.s.sociation, and above all to reproduction.
This necessitates a correction in our a.n.a.lysis. Nature, in many respects, seems to take no interest in individuals. "Life appears to be a current pa.s.sing from one germ to another through the medium of a developed organism." ("Creative Evolution", page 29.)
It seems as if the organism played the part of a thoroughfare. What is important is rather the continuity of progress of which the individuals are only transitory phases. Between these phases again there are no sharp severances; each phase resolves and melts imperceptibly into that which follows. Is not the real problem of heredity to know how, and up to what point, a new individual breaks away from the individuals which produced it? Is not the real mystery of heredity the difference, not the resemblance, occurring between one term and another?
Whatever be its solution, all the individual phases mutually extend and interpenetrate one another. There is a racial memory by which the past is continually acc.u.mulated and preserved. Life"s history is embodied in its present. And that is really the ultimate reason of the perpetual novelty which surprised us just now. The characteristics of biological evolution are thus the same as those of human progress. Once again we find the very stuff of reality in duration. "We must not then speak any longer of life in general as an abstraction, or a mere heading under which we write down all living beings." ("Creative Evolution", page 28.) On the contrary, to it belongs the primordial function of reality. It is a very real current transmitted from generation to generation, organising and pa.s.sing through bodies, without failing or becoming exhausted in any one of them.
We may, already, then, draw one conclusion: Reality, at bottom, is becoming. But such a thesis runs counter to all our familiar ideas.
It is imperative that we should submit it to the test of critical examination and positive verification.
One system of metaphysics, I said some time ago, underlies common-sense, animating and informing it. According to this system, which is the inverse of that which we have just intimated, reality in its very depths is fixity and permanence. This is the completely static conception which sees in being exactly the opposite of becoming: we cannot become, it seems to say, except in so far as we are not. It does not, however, mean to deny movement. But it represents it as fluctuation round invariable types, as a whirling but captive eddy. Every phenomenon appears to it as a transformation which ends where it began, and the result is that the world takes the form of an eternal equilibrium in which "nothing is created, nothing destroyed." The idea does not need much forcing to end in the old supposition of a cyclic return which restores everything to its original conditions. Everything is thus conceived in astronomical periods. All that is left of the universe henceforward is a whirl of atoms in which nothing counts but certain fixed quant.i.ties translated by our systems of equations; the rest has vanished "in algebraical smoke."
There is therefore nothing more or less in the effect than in the group of causes; and the causal relation moves towards ident.i.ty as towards its asymptote.
Such a view of nature is open to many objections, even if it were only a question of inorganised matter. Simple physics already betoken the insufficiency of a purely mechanic conception. The stream of phenomena flows in an irreversible direction and obeys a determined rhythm. "If I wish to prepare myself a gla.s.s of sugar and water, I may do what I like, but I must wait for my sugar to melt." ("Creative Evolution", page 10.) Here are facts which pure mechanism does not take into account, regarding as it does only statically conceived relations, and making time into a measure only, something like a common denominator of concrete successions, a certain number of coincidences from which all true duration remains absent, which would remain unchanged even if the world"s history, instead of opening out in consecutive phases, were to be unfolded before our eyes all at once like a fan. Do we not indeed speak today of aging and atomic separation. If the quant.i.ty of energy is preserved, at least its quality is continually deteriorating. By the side of something which remains constant, the world also contains something which is being used up, dissipated, exhausted, decomposed.
Further still, a specimen of metal, in its molecular structure, preserves an indelible trace of the treatment it has undergone; natural philosophers tell us that there is a "memory of solids." These are all very positive facts which pure mechanism pa.s.ses over. In addition, must we not first of all postulate what will afterwards be preserved or deteriorated? Whence we get another aspect of things: that of genesis and creation; and in reality we register the ascending effort of life as a reality no less startling than mechanic inertia.
Finally, we have a double movement of ascent and descent: such is what life and matter appear to immediate observation. These two currents meet each other, and grapple. It is the drama of evolution, of which Mr Bergson once gave a masterly explanation, in stating the high place which man fills in nature:
"I cannot regard the general evolution and progress of life in the whole of the organised world, the co-ordination and subordination of vital functions to one another in the same living being, the relations which psychology and physiology combined seem bound to establish between brain activity and thought in man, without arriving at this conclusion, that life is an immense effort attempted by thought to obtain of matter something which matter does not wish to give it. Matter is inert; it is the seat of necessity; it proceeds mechanically. It seems as if thought seeks to profit by this mechanical inclination in matter to utilise it for actions, and thus to convert all the creative energy it contains, at least all that this energy possesses which admits of play and external extraction, into contingent movements in s.p.a.ce and events in time which cannot be foreseen. With laborious research it piles up complications to make liberty out of necessity, to compose for itself a matter so subtile, and so mobile, that liberty, by a veritable physical paradox, and thanks to an effort which cannot last long, succeeds in maintaining its equilibrium on this very mobility.
"But it is caught in the snare. The eddy on which it was poised seizes and drags it down. It becomes prisoner of the mechanism it has set up.
Automatism lays hold of it, and life, inevitably forgetting the end which it had determined, which was only to be a means in view of a superior end, is entirely used up in an effort to preserve itself by itself. From the humblest of organised beings to the higher vertebrates which come immediately before man, we witness an attempt which is always foiled and always resumed with more and more art. Man has triumphed; with difficulty, it is true, and so incompletely that a moment"s lapse and inattention on his part surrender him to automatism again. But he has triumphed..." ("Report of the French Philosophical Society", meeting, 2nd May 1901.)
And Mr Bergson adds in another place: ("Creative Evolution", pages 286-287.) "With man consciousness breaks the chain. In man and in man only it obtains its freedom. The whole history of life, till man, had been the history of an effort of consciousness to lift matter, and of the more or less complete crushing of consciousness by matter falling upon it again. The enterprise was paradoxical; if indeed we can speak here, except paradoxically, of enterprise and effort. The task was to take matter, which is necessity itself, and create an instrument of liberty, construct a mechanical system to triumph over mechanism, to employ the determinism of nature to pa.s.s through the meshes of the net it had spread. But everywhere, except in man, consciousness let itself be caught in the net of which it sought to traverse the meshes. It remained taken in the mechanisms it had set up. The automatism which it claimed to be drawing towards liberty enfolds it and drags it down. It has not the strength to get away, because the energy with which it had supplied itself for action is almost entirely employed in maintaining the exceedingly subtile and essentially unstable equilibrium into which it has brought matter. But man does not merely keep his machine going, he succeeds in using it as it pleases him.
"He owes it without doubt to the superiority of his brain, which allows him to construct an unlimited number of motor mechanisms, to oppose new habits to old time after time, and to master automatism by dividing it against itself. He owes it to his language, which furnishes consciousness with an immaterial body in which to become incarnate, thus dispensing it from depending exclusively upon material bodies, the flux of which would drag it down and soon engulf it. He owes it to social life, which stores and preserves efforts as language stores thought, thereby fixing a mean level to which individuals will rise with ease, and which, by means of this initial impulse, prevents average individuals from going to sleep and urges better people to rise higher.
But our brain, our society, and our language are only the varied outer signs of one and the same internal superiority. Each after its fashion, they tell us the unique and exceptional success which life has won at a given moment of its evolution. They translate the difference in nature, and not in degree only, which separates man from the rest of the animal world. They let us see that if, at the end of the broad springboard from which life took off, all others came down, finding the cord stretched too high, man alone has leapt the obstacle."
But man is not on that account isolated in nature: "As the smallest grain of dust forms part of our entire solar system, and is involved along with it in this undivided downward movement which is materiality itself, so all organised beings from the humblest to the highest, from the first origins of life to the times in which we live, and in all places as at all times, do but demonstrate to our eyes a unique impulse contrary to the movement of matter, and, in itself, indivisible. All living beings are connected, and all yield to the same formidable thrust. The animal is supported by the plant, man rides the animal, and the whole of humanity in s.p.a.ce and time is an immense army galloping by the side of each of us, before and behind us, in a spirited charge which can upset all resistance, and leap many obstacles, perhaps even death."
("Creative Evolution", pages 293-294.)
We see with what broad and far-reaching conclusions the new philosophy closes. In the forcible poetry of the pages just quoted its original accent rings deep and pure. Some of its leading theses, moreover, are noted here. But now we must discover the solid foundation of underlying fact.
Let us take first the fact of biological evolution. Why has it been selected as the basis of the system? Is it really a fact, or is it only a more or less conjectural and plausible theory?
Notice in the first instance that the argument from evolution appears at least as a weapon of co-ordination and research admitted in our day by all philosophers, rejected only on the inspiration of preconceived ideas which are completely unscientific; and that it succeeds in the task allotted to it is doubtless already the proof that it responds to some part of reality. And besides, we can go further. "The idea of transformism is already contained in germ in the natural cla.s.sification of organised beings. The naturalist brings resembling organisms together, divides the group into sub-groups, within which the resemblance is still greater, and so on; throughout the operation, the characteristics of the group appear as general themes upon which each of the sub-groups executes its particular variations.
"Now this is precisely the relation we find in the animal world and in the vegetable world between that which produces and what is produced; on the canvas bequeathed by the ancestor to his posterity, and possessed in common by them, each broiders his original pattern." ("Creative Evolution", pages 24-25.)
We may, it is true, ask ourselves whether the genealogical method permits results so far divergent as those presented to us by variety of species. But embryology answers by showing us the highest and most complex forms of life attained every day from very elementary forms; and palaeontology, as it develops, allows us to witness the same spectacle in the universal history of life, as if the succession of phases through which the embryo pa.s.ses were only a recollection and an epitome of the complete past whence it has come. In addition, the phenomena of sudden changes, recently observed, help us to understand more easily the conception which obtrudes itself under so many heads, by diminishing the importance of the apparent lacunae in genealogical continuity. Thus the trend of all our experience is the same.
Now there are some certainties which are only centres of concurrent probabilities; there are some truths determined only by succession of facts, but yet, by their intersection and convergence, sufficiently determined.
"That is how we measure the distance from an inaccessible point, by regarding it time after time from the points to which we have access."
