Few philosophers have had the frankness fairly to admit the necessity of choosing between the 'horns' offered. Reality must be rational, they have said, and since the ordinary intellectualist logic is the only usual test of rationality, reality and logic must agree 'somehow.' Hegel was the first non-mystical writer to face the dilemma squarely and throw away the ordinary logic, saving a pseudo-rationality for the universe by inventing the higher logic of the 'dialectic process.' Bradley holds to the intellectualist logic, and by dint of it convicts the human universe of being irrationality incarnate. But what must be and can be, is, he says; there must and can be relief from _that_ irrationality; and the absolute must already have got the relief in secret ways of its own, impossible for us to guess at. _We_ of course get no relief, so Bradley's is a rather ascetic doctrine. Royce and Taylor accept similar solutions, only they emphasize the irrationality of our finite universe less than Bradley does; and Royce in particular, being unusually 'thick' for an idealist, tries to bring the absolute's secret forms of relief more sympathetically home to our imagination.

Well, what must we do in this tragic predicament? For my own part, I have finally found myself compelled to _give up the logic_, fairly, squarely, and irrevocably. It has an imperishable use in human life, but that use is not to make us theoretically acquainted with the essential nature of reality--just what it is I can perhaps suggest to you a little later. Reality, life, experience, concreteness, immediacy, use what word you will, exceeds our logic, overflows and surrounds it. If you like to employ words eulogistically, as most men do, and so encourage confusion, you may say that reality obeys a higher logic, or enjoys a higher rationality. But I think that even eulogistic words should be used rather to distinguish than to commingle meanings, so I prefer bluntly to call reality if not irrational then at least non-rational in its const.i.tution,--and by reality here I mean reality where things _happen_, all temporal reality without exception. I myself find no good warrant for even suspecting the existence of any reality of a higher denomination than that distributed and strung-along and flowing sort of reality which we finite beings swim in. That is the sort of reality given us, and that is the sort with which logic is so incommensurable. If there be any higher sort of reality--the 'absolute,' for example--that sort, by the confession of those who believe in it, is still less amenable to ordinary logic; it transcends logic and is therefore still less rational in the intellectualist sense, so it cannot help us to save our logic as an adequate definer and confiner of existence.

These sayings will sound queer and dark, probably they will sound quite wild or childish in the absence of explanatory comment. Only the persuasion that I soon can explain them, if not satisfactorily to all of you, at least intelligibly, emboldens me to state them thus baldly as a sort of programme. Please take them as a thesis, therefore, to be defended by later pleading.

I told you that I had long and sincerely wrestled with the dilemma. I have now to confess (and this will probably re-animate your interest) that I should not now be emanc.i.p.ated, not now subordinate logic with so very light a heart, or throw it out of the deeper regions of philosophy to take its rightful and respectable place in the world of simple human practice, if I had not been influenced by a comparatively young and very original french writer, Professor Henri Bergson.

Reading his works is what has made me bold. If I had not read Bergson, I should probably still be blackening endless pages of paper privately, in the hope of making ends meet that were never meant to meet, and trying to discover some mode of conceiving the behavior of reality which should leave no discrepancy between it and the accepted laws of the logic of ident.i.ty. It is certain, at any rate, that without the confidence which being able to lean on Bergson's authority gives me I should never have ventured to urge these particular views of mine upon this ultra-critical audience.

I must therefore, in order to make my own views more intelligible, give some preliminary account of the bergsonian philosophy. But here, as in Fechner's case, I must confine myself only to the features that are essential to the present purpose, and not entangle you in collateral details, however interesting otherwise. For our present purpose, then, the essential contribution of Bergson to philosophy is his criticism of intellectualism. In my opinion he has killed intellectualism definitively and without hope of recovery. I don't see how it can ever revive again in its ancient platonizing role of claiming to be the most authentic, intimate, and exhaustive definer of the nature of reality. Others, as Kant for example, have denied intellectualism's pretensions to define reality _an sich_ or in its absolute capacity; but Kant still leaves it laying down laws--and laws from which there is no appeal--to all our human experience; while what Bergson denies is that its methods give any adequate account of this human experience in its very finiteness. Just how Bergson accomplishes all this I must try to tell in my imperfect way in the next lecture; but since I have already used the words 'logic,' 'logic of ident.i.ty, intellectualistic logic,' and 'intellectualism' so often, and sometimes used them as if they required no particular explanation, it will be wise at this point to say at greater length than heretofore in what sense I take these terms when I claim that Bergson has refuted their pretension to decide what reality can or cannot be. Just what I mean by intellectualism is therefore what I shall try to give a fuller idea of during the remainder of this present hour.

In recent controversies some partic.i.p.ants have shown resentment at being cla.s.sed as intellectualists. I mean to use the word disparagingly, but shall be sorry if it works offence. Intellectualism has its source in the faculty which gives us our chief superiority to the brutes, our power, namely, of translating the crude flux of our merely feeling-experience into a conceptual order. An immediate experience, as yet unnamed or cla.s.sed, is a mere _that_ that we undergo, a thing that asks, '_What_ am I?' When we name and cla.s.s it, we say for the first time what it is, and all these whats are abstract names or concepts. Each concept means a particular _kind_ of thing, and as things seem once for all to have been created in kinds, a far more efficient handling of a given bit of experience begins as soon as we have cla.s.sed the various parts of it. Once cla.s.sed, a thing can be treated by the law of its cla.s.s, and the advantages are endless. Both theoretically and practically this power of framing abstract concepts is one of the sublimest of our human prerogatives. We come back into the concrete from our journey into these abstractions, with an increase both of vision and of power. It is no wonder that earlier thinkers, forgetting that concepts are only man-made extracts from the temporal flux, should have ended by treating them as a superior type of being, bright, changeless, true, divine, and utterly opposed in nature to the turbid, restless lower world. The latter then appears as but their corruption and falsification.

Intellectualism in the vicious sense began when Socrates and Plato taught that what a thing really is, is told us by its _definition_.

Ever since Socrates we have been taught that reality consists of essences, not of appearances, and that the essences of things are known whenever we know their definitions. So first we identify the thing with a concept and then we identify the concept with a definition, and only then, inasmuch as the thing _is_ whatever the definition expresses, are we sure of apprehending the real essence of it or the full truth about it.

So far no harm is done. The misuse of concepts begins with the habit of employing them privatively as well as positively, using them not merely to a.s.sign properties to things, but to deny the very properties with which the things sensibly present themselves. Logic can extract all its possible consequences from any definition, and the logician who is _unerbittlich consequent_ is often tempted, when he cannot extract a certain property from a definition, to deny that the concrete object to which the definition applies can possibly possess that property. The definition that fails to yield it must exclude or negate it. This is Hegel's regular method of establishing his system.

It is but the old story, of a useful practice first becoming a method, then a habit, and finally a tyranny that defeats the end it was used for. Concepts, first employed to make things intelligible, are clung to even when they make them unintelligible. Thus it comes that when once you have conceived things as 'independent,' you must proceed to deny the possibility of any connexion whatever among them, because the notion of connexion is not contained in the definition of independence. For a like reason you must deny any possible forms or modes of unity among things which you have begun by defining as a 'many.' We have cast a glance at Hegel's and Bradley's use of this sort of reasoning, and you will remember Sigwart's epigram that according to it a horseman can never in his life go on foot, or a photographer ever do anything but photograph.

The cla.s.sic extreme in this direction is the denial of the possibility of change, and the consequent branding of the world of change as unreal, by certain philosophers. The definition of A is changeless, so is the definition of B. The one definition cannot change into the other, so the notion that a concrete thing A should change into another concrete thing B is made Out to be contrary to reason. In Mr.

Bradley's difficulty in seeing how sugar can be sweet intellectualism outstrips itself and becomes openly a sort of verbalism. Sugar is just sugar and sweet is just sweet; neither is the other; nor can the word 'is' ever be understood to join any subject to its predicate rationally. Nothing 'between' things can connect them, for 'between'

is just that third thing, 'between,' and would need itself to be connected to the first and second things by two still finer betweens, and so on ad infinitum.

The particular intellectualistic difficulty that had held my own thought so long in a vise was, as we have seen at such tedious length, the impossibility of understanding how 'your' experience and 'mine,'

which 'as such' are defined as not conscious of each other, can nevertheless at the same time be members of a world-experience defined expressly as having all its parts co-conscious, or known together. The definitions are contradictory, so the things defined can in no way be united. You see how unintelligible intellectualism here seems to make the world of our most accomplished philosophers. Neither as they use it nor as we use it does it do anything but make nature look irrational and seem impossible.

In my next lecture, using Bergson as my princ.i.p.al topic, I shall enter into more concrete details and try, by giving up intellectualism frankly, to make, if not the world, at least my own general thesis, less unintelligible.

LECTURE VI

BERGSON AND HIS CRITIQUE OF INTELLECTUALISM

I gave you a very stiff lecture last time, and I fear that this one can be little less so. The best way of entering into it will be to begin immediately with Bergson's philosophy, since I told you that that was what had led me personally to renounce the intellectualistic method and the current notion that logic is an adequate measure of what can or cannot be.

Professor Henri Bergson is a young man, comparatively, as influential philosophers go, having been born at Paris in 1859. His career has been the perfectly routine one of a successful french professor.

Entering the ecole normale superieure at the age of twenty-two, he spent the next seventeen years teaching at _lycees_, provincial or parisian, until his fortieth year, when he was made professor at the said ecole normale. Since 1900 he has been professor at the College de France, and member of the Inst.i.tute since 1900. So far as the outward facts go, Bergson's career has then been commonplace to the utmost.

Neither one of Taine's famous principles of explanation of great men, _the race, the environment, or the moment_, no, nor all three together, will explain that peculiar way of looking at things that const.i.tutes his mental individuality. Originality in men dates from nothing previous, other things date from it, rather. I have to confess that Bergson's originality is so profuse that many of his ideas baffle me entirely. I doubt whether any one understands him all over, so to speak; and I am sure that he would himself be the first to see that this must be, and to confess that things which he himself has not yet thought out clearly, had yet to be mentioned and have a tentative place a.s.signed them in his philosophy. Many of us are profusely original, in that no man can understand us--violently peculiar ways of looking at things are no great rarity. The rarity is when great peculiarity of vision is allied with great lucidity and unusual command of all the cla.s.sic expository apparatus. Bergson's resources in the way of erudition are remarkable, and in the way of expression they are simply phenomenal. This is why in France, where _l'art de bien dire_ counts for so much and is so sure of appreciation, he has immediately taken so eminent a place in public esteem. Old-fashioned professors, whom his ideas quite fail to satisfy, nevertheless speak of his talent almost with bated breath, while the youngsters flock to him as to a master.

If anything can make hard things easy to follow, it is a style like Bergson's. A 'straightforward' style, an american reviewer lately called it; failing to see that such straightforwardness means a flexibility of verbal resource that follows the thought without a crease or wrinkle, as elastic silk underclothing follows the movements of one's body. The lucidity of Bergson's way of putting things is what all readers are first struck by. It seduces you and bribes you in advance to become his disciple. It is a miracle, and he a real magician.

M. Bergson, if I am rightly informed, came into philosophy through the gateway of mathematics. The old antinomies of the infinite were, I imagine, the irritant that first woke his faculties from their dogmatic slumber. You all remember Zeno's famous paradox, or sophism, as many of our logic books still call it, of Achilles and the tortoise. Give that reptile ever so small an advance and the swift runner Achilles can never overtake him, much less get ahead of him; for if s.p.a.ce and time are infinitely divisible (as our intellects tell us they must be), by the time Achilles reaches the tortoise's starting-point, the tortoise has already got ahead of _that_ starting-point, and so on _ad infinitum_, the interval between the pursuer and the pursued growing endlessly minuter, but never becoming wholly obliterated. The common way of showing up the sophism here is by pointing out the ambiguity of the expression 'never can overtake.'

What the word 'never' falsely suggests, it is said, is an infinite duration of time; what it really means is the inexhaustible number of the steps of which the overtaking must consist. But if these steps are infinitely short, a finite time will suffice for them; and in point of fact they do rapidly converge, whatever be the original interval or the contrasted speeds, toward infinitesimal shortness. This proportionality of the shortness of the times to that of the s.p.a.ces required frees us, it is claimed, from the sophism which the word 'never' suggests.

But this criticism misses Zeno's point entirely. Zeno would have been perfectly willing to grant that if the tortoise can be overtaken at all, he can be overtaken in (say) twenty seconds, but he would still have insisted that he can't be overtaken at all. Leave Achilles and the tortoise out of the account altogether, he would have said--they complicate the case unnecessarily. Take any single process of change whatever, take the twenty seconds themselves elapsing. If time be infinitely divisible, and it must be so on intellectualist principles, they simply cannot elapse, their end cannot be reached; for no matter how much of them has already elapsed, before the remainder, however minute, can have wholly elapsed, the earlier half of it must first have elapsed. And this ever re-arising need of making the earlier half elapse _first_ leaves time with always something to do _before_ the last thing is done, so that the last thing never gets done. Expressed in bare numbers, it is like the convergent series 1/2 plus 1/4 plus 1/8..., of which the limit is one. But this limit, simply because it is a limit, stands outside the series, the value of which approaches it indefinitely but never touches it. If in the natural world there were no other way of getting things save by such successive addition of their logically involved fractions, no complete units or whole things would ever come into being, for the fractions' sum would always leave a remainder. But in point of fact nature doesn't make eggs by making first half an egg, then a quarter, then an eighth, etc., and adding them together. She either makes a whole egg at once or none at all, and so of all her other units. It is only in the sphere of change, then, where one phase of a thing must needs come into being before another phase can come that Zeno's paradox gives trouble.

And it gives trouble then only if the succession of steps of change be infinitely divisible. If a bottle had to be emptied by an infinite number of successive decrements, it is mathematically impossible that the emptying should ever positively terminate. In point of fact, however, bottles and coffee-pots empty themselves by a finite number of decrements, each of definite amount. Either a whole drop emerges or nothing emerges from the spout. If all change went thus drop-wise, so to speak, if real time sprouted or grew by units of duration of determinate amount, just as our perceptions of it grow by pulses, there would be no zenonian paradoxes or kantian antinomies to trouble us. All our sensible experiences, as we get them immediately, do thus change by discrete pulses of perception, each of which keeps us saying 'more, more, more,' or 'less, less, less,' as the definite increments or diminutions make themselves felt. The discreteness is still more obvious when, instead of old things changing, they cease, or when altogether new things come. Fechner's term of the 'threshold,' which has played such a part in the psychology of perception, is only one way of naming the quant.i.tative discreteness in the change of all our sensible experiences. They come to us in drops. Time itself comes in drops.

Our ideal decomposition of the drops which are all that we feel into still finer fractions is but an incident in that great transformation of the perceptual order into a conceptual order of which I spoke in my last lecture. It is made in the interest of our rationalizing intellect solely. The times directly _felt_ in the experiences of living subjects have originally no common measure. Let a lump of sugar melt in a gla.s.s, to use one of M. Bergson's instances. We feel the time to be long while waiting for the process to end, but who knows how long or how short it feels to the sugar? All _felt_ times coexist and overlap or compenetrate each other thus vaguely, but the artifice of plotting them on a common scale helps us to reduce their aboriginal confusion, and it helps us still more to plot, against the same scale, the successive possible steps into which nature's various changes may be resolved, either sensibly or conceivably. We thus straighten out the aboriginal privacy and vagueness, and can date things publicly, as it were, and by each other. The notion of one objective and 'evenly flowing' time, cut into numbered instants, applies itself as a common measure to all the steps and phases, no matter how many, into which we cut the processes of nature. They are now definitely contemporary, or later or earlier one than another, and we can handle them mathematically, as we say, and far better, practically as well as theoretically, for having thus correlated them one to one with each other on the common schematic or conceptual time-scale.

Motion, to take a good example, is originally a turbid sensation, of which the native shape is perhaps best preserved in the phenomenon of vertigo. In vertigo we feel that movement _is_, and is more or less violent or rapid, more or less in this direction or that, more or less alarming or sickening. But a man subject to vertigo may gradually learn to co-ordinate his felt motion with his real position and that of other things, and intellectualize it enough to succeed at last in walking without staggering. The mathematical mind similarly organizes motion in its way, putting it into a logical definition: motion is now conceived as 'the occupancy of serially successive points of s.p.a.ce at serially successive instants of time.' With such a definition we escape wholly from the turbid privacy of sense. But do we not also escape from sense-reality altogether? Whatever motion really may be, it surely is not static; but the definition we have gained is of the absolutely static. It gives a set of one-to-one relations between s.p.a.ce-points and time-points, which relations themselves are as fixed as the points are. It gives _positions_ a.s.signable ad infinitum, but how the body gets from one position to another it omits to mention.

The body gets there by moving, of course; but the conceived positions, however numerously multiplied, contain no element of movement, so Zeno, using nothing but them in his discussion, has no alternative but to say that our intellect repudiates motion as a non-reality.

Intellectualism here does what I said it does--it makes experience less instead of more intelligible.

We of course need a stable scheme of concepts, stably related with one another, to lay hold of our experiences and to co-ordinate them withal. When an experience comes with sufficient saliency to stand out, we keep the thought of it for future use, and store it in our conceptual system. What does not of itself stand out, we learn to _cut_ out; so the system grows completer, and new reality, as it comes, gets named after and conceptually strung upon this or that element of it which we have already established. The immutability of such an abstract system is its great practical merit; the same identical terms and relations in it can always be recovered and referred to--change itself is just such an unalterable concept. But all these abstract concepts are but as flowers gathered, they are only moments dipped out from the stream of time, snap-shots taken, as by a kinetoscopic camera, at a life that in its original coming is continuous. Useful as they are as samples of the garden, or to re-enter the stream with, or to insert in our revolving lantern, they have no value but these practical values. You cannot explain by them what makes any single phenomenon be or go--you merely dot out the path of appearances which it traverses. For you cannot make continuous being out of discontinuities, and your concepts are discontinuous. The stages into which you a.n.a.lyze a change are _states_, the change itself goes on between them. It lies along their intervals, inhabits what your definition fails to gather up, and thus eludes conceptual explanation altogether.

'When the mathematician,' Bergson writes, 'calculates the state of a system at the end of a time _t_, nothing need prevent him from supposing that betweenwhiles the universe vanishes, in order suddenly to appear again at the due moment in the new configuration. It is only the _t_-th moment that counts--that which flows throughout the intervals, namely real time, plays no part in his calculation.... In short, the world on which the mathematician operates is a world which dies and is born anew at every instant, like the world which Descartes thought of when he spoke of a continued creation.' To know adequately what really _happens_ we ought, Bergson insists, to see into the intervals, but the mathematician sees only their extremities. He fixes only a few results, he dots a curve and then interpolates, he subst.i.tutes a tracing for a reality.

This being so undeniably the case, the history of the way in which philosophy has dealt with it is curious. The ruling tradition in philosophy has always been the platonic and aristotelian belief that fixity is a n.o.bler and worthier thing than change. Reality must be one and unalterable. Concepts, being themselves fixities, agree best with this fixed nature of truth, so that for any knowledge of ours to be quite true it must be knowledge by universal concepts rather than by particular experiences, for these notoriously are mutable and corruptible. This is the tradition known as rationalism in philosophy, and what I have called intellectualism is only the extreme application of it. In spite of sceptics and empiricists, in spite of Protagoras, Hume, and James Mill, rationalism has never been seriously questioned, for its sharpest critics have always had a tender place in their hearts for it, and have obeyed some of its mandates. They have not been consistent; they have played fast and loose with the enemy; and Bergson alone has been radical.

To show what I mean by this, let me contrast his procedure with that of some of the transcendentalist philosophers whom I have lately mentioned. Coming after Kant, these pique themselves on being 'critical,' on building in fact upon Kant's 'critique' of pure reason.

What that critique professed to establish was this, that concepts do not apprehend reality, but only such appearances as our senses feed out to them. They give immutable intellectual forms to these appearances, it is true, but the reality _an sich_ from which in ultimate resort the sense-appearances have to come remains forever unintelligible to our intellect. Take motion, for example. Sensibly, motion comes in drops, waves, or pulses; either some actual amount of it, or none, being apprehended. This amount is the datum or _gabe_ which reality feeds out to our intellectual faculty; but our intellect makes of it a task or _aufgabe_--this pun is one of the most memorable of Kant's formulas--and insists that in every pulse of it an infinite number of successive minor pulses shall be ascertainable. These minor pulses _we_ can indeed _go on_ to ascertain or to compute indefinitely if we have patience; but it would contradict the definition of an infinite number to suppose the endless series of them to have actually counted _themselves_ out piecemeal. Zeno made this manifest; so the infinity which our intellect requires of the sense-datum is thus a future and potential rather than a past and actual infinity of structure. The datum after it has made itself must be decompos_able_ ad infinitum by our conception, but of the steps by which that structure actually got composed we know nothing. Our intellect casts, in short, no ray of light on the processes by which experiences _get made_.

Kant's monistic successors have in general found the data of immediate experience even more self-contradictory, when intellectually treated, than Kant did. Not only the character of infinity involved in the relation of various empirical data to their 'conditions,' but the very notion that empirical things should be related to one another at all, has seemed to them, when the intellectualistic fit was upon them, full of paradox and contradiction. We saw in a former lecture numerous instances of this from Hegel, Bradley, Royce, and others. We saw also where the solution of such an intolerable state of things was sought for by these authors. Whereas Kant had placed it outside of and _before_ our experience, in the _dinge an sich_ which are the causes of the latter, his monistic successors all look for it either _after_ experience, as its absolute completion, or else consider it to be even now implicit within experience as its ideal signification. Kant and his successors look, in short, in diametrically opposite directions.

Do not be misled by Kant's admission of theism into his system.

His G.o.d is the ordinary dualistic G.o.d of Christianity, to whom his philosophy simply opens the door; he has nothing whatsoever in common with the 'absolute spirit' set up by his successors. So far as this absolute spirit is logically derived from Kant, it is not from his G.o.d, but from entirely different elements of his philosophy. First from his notion that an unconditioned totality of the conditions of any experience must be a.s.signable; and then from his other notion that the presence of some witness, or ego of apperception, is the most universal of all the conditions in question. The post-kantians make of the witness-condition what is called a concrete universal, an individualized all-witness or world-self, which shall imply in its rational const.i.tution each and all of the other conditions put together, and therefore necessitate each and all of the conditioned experiences.

Abridgments like this of other men's opinions are very unsatisfactory, they always work injustice; but in this case those of you who are familiar with the literature will see immediately what I have in mind; and to the others, if there be any here, it will suffice to say that what I am trying so pedantically to point out is only the fact that monistic idealists after Kant have invariably sought relief from the supposed contradictions of our world of sense by looking forward toward an _ens rationis_ conceived as its integration or logical completion, while he looked backward toward non-rational _dinge an sich_ conceived as its cause. Pluralistic empiricists, on the other hand, have remained in the world of sense, either navely and because they overlooked the intellectualistic contradictions, or because, not able to ignore them, they thought they could refute them by a superior use of the same intellectualistic logic. Thus it is that John Mill pretends to refute the Achilles-tortoise fallacy.

The important point to notice here is the intellectualist logic. Both sides treat it as authoritative, but they do so capriciously: the absolutists smashing the world of sense by its means, the empiricists smashing the absolute--for the absolute, they say, is the quintessence of all logical contradictions. Neither side attains consistency.

The Hegelians have to invoke a higher logic to supersede the purely destructive efforts of their first logic. The empiricists use their logic against the absolute, but refuse to use it against finite experience. Each party uses it or drops it to suit the vision it has faith in, but neither impugns in principle its general theoretic authority.

Bergson alone challenges its theoretic authority in principle. He alone denies that mere conceptual logic can tell us what is impossible or possible in the world of being or fact; and he does so for reasons which at the same time that they rule logic out from lordship over the whole of life, establish a vast and definite sphere of influence where its sovereignty is indisputable. Bergson's own text, felicitous as it is, is too intricate for quotation, so I must use my own inferior words in explaining what I mean by saying this.

In the first place, logic, giving primarily the relations between concepts as such, and the relations between natural facts only secondarily or so far as the facts have been already identified with concepts and defined by them, must of course stand or fall with the conceptual method. But the conceptual method is a transformation which the flux of life undergoes at our hands in the interests of practice essentially and only subordinately in the interests of theory. We live forward, we understand backward, said a danish writer; and to understand life by concepts is to arrest its movement, cutting it up into bits as if with scissors, and immobilizing these in our logical herbarium where, comparing them as dried specimens, we can ascertain which of them statically includes or excludes which other. This treatment supposes life to have already accomplished itself, for the concepts, being so many views taken after the fact, are retrospective and post mortem. Nevertheless we can draw conclusions from them and project them into the future. We cannot learn from them how life made itself go, or how it will make itself go; but, on the supposition that its ways of making itself go are unchanging, we can calculate what positions of imagined arrest it will exhibit hereafter under given conditions. We can compute, for instance, at what point Achilles will be, and where the tortoise will be, at the end of the twentieth minute. Achilles may then be at a point far ahead; but the full detail of how he will have managed practically to get there our logic never gives us--we have seen, indeed, that it finds that its results contradict the facts of nature. The computations which the other sciences make differ in no respect from those of mathematics. The concepts used are all of them dots through which, by interpolation or extrapolation, curves are drawn, while along the curves other dots are found as consequences. The latest refinements of logic dispense with the curves altogether, and deal solely with the dots and their correspondences each to each in various series. The authors of these recent improvements tell us expressly that their aim is to abolish the last vestiges of intuition, _videlicet_ of concrete reality, from the field of reasoning, which then will operate literally on mental dots or bare abstract units of discourse, and on the ways in which they may be strung in naked series.

This is all very esoteric, and my own understanding of it is most likely misunderstanding. So I speak here only by way of brief reminder to those who know. For the rest of us it is enough to recognize this fact, that altho by means of concepts cut out from the sensible flux of the past, we can re-descend upon the future flux and, making another cut, say what particular thing is likely to be found there; and that altho in this sense concepts give us knowledge, and may be said to have some theoretic value (especially when the particular thing foretold is one in which we take no present practical interest); yet in the deeper sense of giving _insight_ they have no theoretic value, for they quite fail to connect us with the inner life of the flux, or with the causes that govern its direction. Instead of being interpreters of reality, concepts negate the inwardness of reality altogether. They make the whole notion of a causal influence between finite things incomprehensible. No real activities and indeed no real connexions of any kind can obtain if we follow the conceptual logic; for to be distinguishable, according to what I call intellectualism, is to be incapable of connexion. The work begun by Zeno, and continued by Hume, Kant, Herbart, Hegel, and Bradley, does not stop till sensible reality lies entirely disintegrated at the feet of 'reason.'

Of the 'absolute' reality which reason proposes to subst.i.tute for sensible reality I shall have more to say presently. Meanwhile you see what Professor Bergson means by insisting that the function of the intellect is practical rather than theoretical. Sensible reality is too concrete to be entirely manageable--look at the narrow range of it which is all that any animal, living in it exclusively as he does, is able to compa.s.s. To get from one point in it to another we have to plough or wade through the whole intolerable interval. No detail is spared us; it is as bad as the barbed-wire complications at Port Arthur, and we grow old and die in the process. But with our faculty of abstracting and fixing concepts we are there in a second, almost as if we controlled a fourth dimension, skipping the intermediaries as by a divine winged power, and getting at the exact point we require without entanglement with any context. What we do in fact is to _harness up_ reality in our conceptual systems in order to drive it the better. This process is practical because all the termini to which we drive are _particular_ termini, even when they are facts of the mental order. But the sciences in which the conceptual method chiefly celebrates its triumphs are those of s.p.a.ce and matter, where the transformations of external things are dealt with. To deal with moral facts conceptually, we have first to transform them, subst.i.tute brain-diagrams or physical metaphors, treat ideas as atoms, interests as mechanical forces, our conscious 'selves' as 'streams,' and the like. Paradoxical effect! as Bergson well remarks, if our intellectual life were not practical but destined to reveal the inner natures.

One would then suppose that it would find itself most at home in the domain of its own intellectual realities. But it is precisely there that it finds itself at the end of its tether. We know the inner movements of our spirit only perceptually. We feel them live in us, but can give no distinct account of their elements, nor definitely predict their future; while things that lie along the world of s.p.a.ce, things of the sort that we literally _handle_, are what our intellects cope with most successfully. Does not this confirm us in the view that the original and still surviving function of our intellectual life is to guide us in the practical adaptation of our expectancies and activities?

One can easily get into a verbal mess at this point, and my own experience with pragmatism' makes me shrink from the dangers that lie in the word 'practical,' and far rather than stand out against you for that word, I am quite willing to part company with Professor Bergson, and to ascribe a primarily theoretical function to our intellect, provided you on your part then agree to discriminate 'theoretic' or scientific knowledge from the deeper 'speculative' knowledge aspired to by most philosophers, and concede that theoretic knowledge, which is knowledge _about_ things, as distinguished from living or sympathetic acquaintance with them, touches only the outer surface of reality. The surface which theoretic knowledge taken in this sense covers may indeed be enormous in extent; it may dot the whole diameter of s.p.a.ce and time with its conceptual creations; but it does not penetrate a millimeter into the solid dimension. That inner dimension of reality is occupied by the _activities_ that keep it going, but the intellect, speaking through Hume, Kant & Co., finds itself obliged to deny, and persists in denying, that activities have any intelligible existence. What exists for _thought_, we are told, is at most the results that we illusorily ascribe to such activities, strung along the surfaces of s.p.a.ce and time by _regeln der verknupfung_, laws of nature which state only coexistences and successions.[1]

Thought deals thus solely with surfaces. It can name the thickness of reality, but it cannot fathom it, and its insufficiency here is essential and permanent, not temporary.

The only way in which to apprehend reality's thickness is either to experience it directly by being a part of reality one's self, or to evoke it in imagination by sympathetically divining some one else's inner life. But what we thus immediately experience or concretely divine is very limited in duration, whereas abstractly we are able to conceive eternities. Could we feel a million years concretely as we now feel a pa.s.sing minute, we should have very little employment for our conceptual faculty. We should know the whole period fully at every moment of its pa.s.sage, whereas we must now construct it laboriously by means of concepts which we project. Direct acquaintance and conceptual knowledge are thus complementary of each other; each remedies the other's defects. If what we care most about be the synoptic treatment of phenomena, the vision of the far and the gathering of the scattered like, we must follow the conceptual method. But if, as metaphysicians, we are more curious about the inner nature of reality or about what really makes it go, we must turn our backs upon our winged concepts altogether, and bury ourselves in the thickness of those pa.s.sing moments over the surface of which they fly, and on particular points of which they occasionally rest and perch.

Professor Bergson thus inverts the traditional platonic doctrine absolutely. Instead of intellectual knowledge being the profounder, he calls it the more superficial. Instead of being the only adequate knowledge, it is grossly inadequate, and its only superiority is the practical one of enabling us to make short cuts through experience and thereby to save time. The one thing it cannot do is to reveal the nature of things--which last remark, if not clear already, will become clearer as I proceed. Dive back into the flux itself, then, Bergson tells us, if you wish to _know_ reality, that flux which Platonism, in its strange belief that only the immutable is excellent, has always spurned; turn your face toward sensation, that flesh-bound thing which rationalism has always loaded with abuse.--This, you see, is exactly the opposite remedy from that of looking forward into the absolute, which our idealistic contemporaries prescribe. It violates our mental habits, being a kind of pa.s.sive and receptive listening quite contrary to that effort to react noisily and verbally on everything, which is our usual intellectual pose.

What, then, are the peculiar features in the perceptual flux which the conceptual translation so fatally leaves out?

The essence of life is its continuously changing character; but our concepts are all discontinuous and fixed, and the only mode of making them coincide with life is by arbitrarily supposing positions of arrest therein. With such arrests our concepts may be made congruent.

But these concepts are not _parts_ of reality, not real positions taken by it, but _suppositions_ rather, notes taken by ourselves, and you can no more dip up the substance of reality with them than you can dip up water with a net, however finely meshed.

When we conceptualize, we cut out and fix, and exclude everything but what we have fixed. A concept means a _that-and-no-other_.

Conceptually, time excludes s.p.a.ce; motion and rest exclude each other; approach excludes contact; presence excludes absence; unity excludes plurality; independence excludes relativity; 'mine' excludes 'yours'; this connexion excludes that connexion--and so on indefinitely; whereas in the real concrete sensible flux of life experiences compenetrate each other so that it is not easy to know just what is excluded and what not. Past and future, for example, conceptually separated by the cut to which we give the name of present, and defined as being the opposite sides of that cut, are to some extent, however brief, co-present with each other throughout experience. The literally present moment is a purely verbal supposition, not a position; the only present ever realized concretely being the 'pa.s.sing moment' in which the dying rearward of time and its dawning future forever mix their lights. Say 'now' and it _was_ even while you say it.
