Moreover, once true, always true, of those same mental objects.
Truth here has an "eternal" character. If you can find a concrete thing anywhere that is "one" or "white" or "gray," or an "effect,"
then your principles will everlastingly apply to it. It is but a case of ascertaining the kind, and then applying the law of its kind to the particular object. You are sure to get truth if you can but name the kind rightly, for your mental relations hold good of everything of that kind without exception. If you then, nevertheless, failed to get truth concretely, you would say that you had cla.s.sed your real objects wrongly.
In this realm of mental relations, truth again is an affair of leading. We relate one abstract idea with another, framing in the end great systems of logical and mathematical truth, under the respective terms of which the sensible facts of experience eventually arrange themselves, so that our eternal truths hold good of realities also. This marriage of fact and theory is endlessly fertile. What we say is here already true in advance of special verification, IF WE HAVE SUBSUMED OUR OBJECTS RIGHTLY. Our ready- made ideal framework for all sorts of possible objects follows from the very structure of our thinking. We can no more play fast and loose with these abstract relations than we can do so with our sense-experiences. They coerce us; we must treat them consistently, whether or not we like the results. The rules of addition apply to our debts as rigorously as to our a.s.sets. The hundredth decimal of pi, the ratio of the circ.u.mference to its diameter, is predetermined ideally now, tho no one may have computed it. If we should ever need the figure in our dealings with an actual circle we should need to have it given rightly, calculated by the usual rules; for it is the same kind of truth that those rules elsewhere calculate.
Between the coercions of the sensible order and those of the ideal order, our mind is thus wedged tightly. Our ideas must agree with realities, be such realities concrete or abstract, be they facts or be they principles, under penalty of endless inconsistency and frustration. So far, intellectualists can raise no protest. They can only say that we have barely touched the skin of the matter.
Realities mean, then, either concrete facts, or abstract kinds of things and relations perceived intuitively between them. They furthermore and thirdly mean, as things that new ideas of ours must no less take account of, the whole body of other truths already in our possession. But what now does "agreement" with such three-fold realities mean?--to use again the definition that is current.
Here it is that pragmatism and intellectualism begin to part company. Primarily, no doubt, to agree means to copy, but we saw that the mere word "clock" would do instead of a mental picture of its works, and that of many realities our ideas can only be symbols and not copies. "Past time," "power," "spontaneity"--how can our mind copy such realities?
To "agree" in the widest sense with a reality, CAN ONLY MEAN TO BE GUIDED EITHER STRAIGHT UP TO IT OR INTO ITS SURROUNDINGS, OR TO BE PUT INTO SUCH WORKING TOUCH WITH IT AS TO HANDLE EITHER IT OR SOMETHING CONNECTED WITH IT BETTER THAN IF WE DISAGREED. Better either intellectually or practically! And often agreement will only mean the negative fact that nothing contradictory from the quarter of that reality comes to interfere with the way in which our ideas guide us elsewhere. To copy a reality is, indeed, one very important way of agreeing with it, but it is far from being essential. The essential thing is the process of being guided. Any idea that helps us to DEAL, whether practically or intellectually, with either the reality or its belongings, that doesn"t entangle our progress in frustrations, that FITS, in fact, and adapts our life to the reality"s whole setting, will agree sufficiently to meet the requirement. It will hold true of that reality.
Thus, NAMES are just as "true" or "false" as definite mental pictures are. They set up similar verification-processes, and lead to fully equivalent practical results.
All human thinking gets discursified; we exchange ideas; we lend and borrow verifications, get them from one another by means of social intercourse. All truth thus gets verbally built out, stored up, and made available for everyone. Hence, we must TALK consistently just as we must THINK consistently: for both in talk and thought we deal with kinds. Names are arbitrary, but once understood they must be kept to. We mustn"t now call Abel "Cain" or Cain "Abel." If we do, we ungear ourselves from the whole book of Genesis, and from all its connexions with the universe of speech and fact down to the present time. We throw ourselves out of whatever truth that entire system of speech and fact may embody.
The overwhelming majority of our true ideas admit of no direct or face-to-face verification-those of past history, for example, as of Cain and Abel. The stream of time can be remounted only verbally, or verified indirectly by the present prolongations or effects of what the past harbored. Yet if they agree with these verbalities and effects, we can know that our ideas of the past are true. AS TRUE AS PAST TIME ITSELF WAS, so true was Julius Caesar, so true were antediluvian monsters, all in their proper dates and settings. That past time itself was, is guaranteed by its coherence with everything that"s present. True as the present is, the past was also.
Agreement thus turns out to be essentially an affair of leading-- leading that is useful because it is into quarters that contain objects that are important. True ideas lead us into useful verbal and conceptual quarters as well as directly up to useful sensible termini. They lead to consistency, stability and flowing human intercourse. They lead away from excentricity and isolation, from foiled and barren thinking. The untrammeled flowing of the leading- process, its general freedom from clash and contradiction, pa.s.ses for its indirect verification; but all roads lead to Rome, and in the end and eventually, all true processes must lead to the face of directly verifying sensible experiences SOMEWHERE, which somebody"s ideas have copied.
Such is the large loose way in which the pragmatist interprets the word agreement. He treats it altogether practically. He lets it cover any process of conduction from a present idea to a future terminus, provided only it run prosperously. It is only thus that "scientific" ideas, flying as they do beyond common sense, can be said to agree with their realities. It is, as I have already said, as if reality were made of ether, atoms or electrons, but we mustn"t think so literally. The term "energy" doesn"t even pretend to stand for anything "objective." It is only a way of measuring the surface of phenomena so as to string their changes on a simple formula.
Yet in the choice of these man-made formulas we cannot be capricious with impunity any more than we can be capricious on the common-sense practical level. We must find a theory that will WORK; and that means something extremely difficult; for our theory must mediate between all previous truths and certain new experiences. It must derange common sense and previous belief as little as possible, and it must lead to some sensible terminus or other that can be verified exactly. To "work" means both these things; and the squeeze is so tight that there is little loose play for any hypothesis. Our theories are wedged and controlled as nothing else is. Yet sometimes alternative theoretic formulas are equally compatible with all the truths we know, and then we choose between them for subjective reasons. We choose the kind of theory to which we are already partial; we follow "elegance" or "economy." Clerk Maxwell somewhere says it would be "poor scientific taste" to choose the more complicated of two equally well-evidenced conceptions; and you will all agree with him. Truth in science is what gives us the maximum possible sum of satisfactions, taste included, but consistency both with previous truth and with novel fact is always the most imperious claimant.
I have led you through a very sandy desert. But now, if I may be allowed so vulgar an expression, we begin to taste the milk in the cocoanut. Our rationalist critics here discharge their batteries upon us, and to reply to them will take us out from all this dryness into full sight of a momentous philosophical alternative.
Our account of truth is an account of truths in the plural, of processes of leading, realized in rebus, and having only this quality in common, that they PAY. They pay by guiding us into or towards some part of a system that dips at numerous points into sense-percepts, which we may copy mentally or not, but with which at any rate we are now in the kind of commerce vaguely designated as verification. Truth for us is simply a collective name for verification-processes, just as health, wealth, strength, etc., are names for other processes connected with life, and also pursued because it pays to pursue them. Truth is MADE, just as health, wealth and strength are made, in the course of experience.
Here rationalism is instantaneously up in arms against us. I can imagine a rationalist to talk as follows:
"Truth is not made," he will say; "it absolutely obtains, being a unique relation that does not wait upon any process, but shoots straight over the head of experience, and hits its reality every time. Our belief that yon thing on the wall is a clock is true already, altho no one in the whole history of the world should verify it. The bare quality of standing in that transcendent relation is what makes any thought true that possesses it, whether or not there be verification. You pragmatists put the cart before the horse in making truth"s being reside in verification-processes.
These are merely signs of its being, merely our lame ways of ascertaining after the fact, which of our ideas already has possessed the wondrous quality. The quality itself is timeless, like all essences and natures. Thoughts partake of it directly, as they partake of falsity or of irrelevancy. It can"t be a.n.a.lyzed away into pragmatic consequences."
The whole plausibility of this rationalist tirade is due to the fact to which we have already paid so much attention. In our world, namely, abounding as it does in things of similar kinds and similarly a.s.sociated, one verification serves for others of its kind, and one great use of knowing things is to be led not so much to them as to their a.s.sociates, especially to human talk about them.
The quality of truth, obtaining ante rem, pragmatically means, then, the fact that in such a world innumerable ideas work better by their indirect or possible than by their direct and actual verification.
Truth ante rem means only verifiability, then; or else it is a case of the stock rationalist trick of treating the NAME of a concrete phenomenal reality as an independent prior ent.i.ty, and placing it behind the reality as its explanation. Professor Mach quotes somewhere an epigram of Lessing"s:
Sagt Hanschen Schlau zu Vetter Fritz, "Wie kommt es, Vetter Fritzen, Da.s.s grad" die Reichsten in der Welt, Das meiste Geld besitzen?"
Hanschen Schlau here treats the principle "wealth" as something distinct from the facts denoted by the man"s being rich. It antedates them; the facts become only a sort of secondary coincidence with the rich man"s essential nature.
In the case of "wealth" we all see the fallacy. We know that wealth is but a name for concrete processes that certain men"s lives play a part in, and not a natural excellence found in Messrs. Rockefeller and Carnegie, but not in the rest of us.
Like wealth, health also lives in rebus. It is a name for processes, as digestion, circulation, sleep, etc., that go on happily, tho in this instance we are more inclined to think of it as a principle and to say the man digests and sleeps so well BECAUSE he is so healthy.
With "strength" we are, I think, more rationalistic still, and decidedly inclined to treat it as an excellence pre-existing in the man and explanatory of the herculean performances of his muscles.
With "truth" most people go over the border entirely, and treat the rationalistic account as self-evident. But really all these words in TH are exactly similar. Truth exists ante rem just as much and as little as the other things do.
The scholastics, following Aristotle, made much of the distinction between habit and act. Health in actu means, among other things, good sleeping and digesting. But a healthy man need not always be sleeping, or always digesting, any more than a wealthy man need be always handling money, or a strong man always lifting weights. All such qualities sink to the status of "habits" between their times of exercise; and similarly truth becomes a habit of certain of our ideas and beliefs in their intervals of rest from their verifying activities. But those activities are the root of the whole matter, and the condition of there being any habit to exist in the intervals.
"The true," to put it very briefly, is only the expedient in the way of our thinking, just as "the right" is only the expedient in the way of our behaving. Expedient in almost any fashion; and expedient in the long run and on the whole of course; for what meets expediently all the experience in sight won"t necessarily meet all farther experiences equally satisfactorily. Experience, as we know, has ways of BOILING OVER, and making us correct our present formulas.
The "absolutely" true, meaning what no farther experience will ever alter, is that ideal vanishing-point towards which we imagine that all our temporary truths will some day converge. It runs on all fours with the perfectly wise man, and with the absolutely complete experience; and, if these ideals are ever realized, they will all be realized together. Meanwhile we have to live to-day by what truth we can get to-day, and be ready to-morrow to call it falsehood.
Ptolemaic astronomy, euclidean s.p.a.ce, aristotelian logic, scholastic metaphysics, were expedient for centuries, but human experience has boiled over those limits, and we now call these things only relatively true, or true within those borders of experience.
"Absolutely" they are false; for we know that those limits were casual, and might have been transcended by past theorists just as they are by present thinkers.
When new experiences lead to retrospective judgments, using the past tense, what these judgments utter WAS true, even tho no past thinker had been led there. We live forwards, a Danish thinker has said, but we understand backwards. The present sheds a backward light on the world"s previous processes. They may have been truth-processes for the actors in them. They are not so for one who knows the later revelations of the story.
This regulative notion of a potential better truth to be established later, possibly to be established some day absolutely, and having powers of retroactive legislation, turns its face, like all pragmatist notions, towards concreteness of fact, and towards the future. Like the half-truths, the absolute truth will have to be MADE, made as a relation incidental to the growth of a ma.s.s of verification-experience, to which the half-true ideas are all along contributing their quota.
I have already insisted on the fact that truth is made largely out of previous truths. Men"s beliefs at any time are so much experience funded. But the beliefs are themselves parts of the sum total of the world"s experience, and become matter, therefore, for the next day"s funding operations. So far as reality means experienceable reality, both it and the truths men gain about it are everlastingly in process of mutation-mutation towards a definite goal, it may be--but still mutation.
Mathematicians can solve problems with two variables. On the Newtonian theory, for instance, acceleration varies with distance, but distance also varies with acceleration. In the realm of truth- processes facts come independently and determine our beliefs provisionally. But these beliefs make us act, and as fast as they do so, they bring into sight or into existence new facts which re- determine the beliefs accordingly. So the whole coil and ball of truth, as it rolls up, is the product of a double influence. Truths emerge from facts; but they dip forward into facts again and add to them; which facts again create or reveal new truth (the word is indifferent) and so on indefinitely. The "facts" themselves meanwhile are not TRUE. They simply ARE. Truth is the function of the beliefs that start and terminate among them.
The case is like a s...o...b..ll"s growth, due as it is to the distribution of the snow on the one hand, and to the successive pushes of the boys on the other, with these factors co-determining each other incessantly.
The most fateful point of difference between being a rationalist and being a pragmatist is now fully in sight. Experience is in mutation, and our psychological ascertainments of truth are in mutation--so much rationalism will allow; but never that either reality itself or truth itself is mutable. Reality stands complete and ready-made from all eternity, rationalism insists, and the agreement of our ideas with it is that unique una.n.a.lyzable virtue in them of which she has already told us. As that intrinsic excellence, their truth has nothing to do with our experiences. It adds nothing to the content of experience. It makes no difference to reality itself; it is supervenient, inert, static, a reflexion merely. It doesn"t EXIST, it HOLDS or OBTAINS, it belongs to another dimension from that of either facts or fact-relations, belongs, in short, to the epistemological dimension--and with that big word rationalism closes the discussion.
Thus, just as pragmatism faces forward to the future, so does rationalism here again face backward to a past eternity. True to her inveterate habit, rationalism reverts to "principles," and thinks that when an abstraction once is named, we own an oracular solution.
The tremendous pregnancy in the way of consequences for life of this radical difference of outlook will only become apparent in my later lectures. I wish meanwhile to close this lecture by showing that rationalism"s sublimity does not save it from inanity.
When, namely, you ask rationalists, instead of accusing pragmatism of desecrating the notion of truth, to define it themselves by saying exactly what THEY understand by it, the only positive attempts I can think of are these two:
1. "Truth is just the system of propositions which have an un- conditional claim to be recognized as valid." [Footnote: A. E.
Taylor, Philosophical Review, vol. xiv, p. 288.]
2. Truth is a name for all those judgments which we find ourselves under obligation to make by a kind of imperative duty. [Footnote: H.
Rickert, Der Gegenstand der Erkenntniss, chapter on "Die Urtheilsnothwendigkeit."]
The first thing that strikes one in such definitions is their unutterable triviality. They are absolutely true, of course, but absolutely insignificant until you handle them pragmatically. What do you mean by "claim" here, and what do you mean by "duty"? As summary names for the concrete reasons why thinking in true ways is overwhelmingly expedient and good for mortal men, it is all right to talk of claims on reality"s part to be agreed with, and of obligations on our part to agree. We feel both the claims and the obligations, and we feel them for just those reasons.
But the rationalists who talk of claim and obligation EXPRESSLY SAY THAT THEY HAVE NOTHING TO DO WITH OUR PRACTICAL INTERESTS OR PERSONAL REASONS. Our reasons for agreeing are psychological facts, they say, relative to each thinker, and to the accidents of his life. They are his evidence merely, they are no part of the life of truth itself. That life transacts itself in a purely logical or epistemological, as distinguished from a psychological, dimension, and its claims antedate and exceed all personal motivations whatsoever. Tho neither man nor G.o.d should ever ascertain truth, the word would still have to be defined as that which OUGHT to be ascertained and recognized.
There never was a more exquisite example of an idea abstracted from the concretes of experience and then used to oppose and negate what it was abstracted from.
Philosophy and common life abound in similar instances. The "sentimentalist fallacy" is to shed tears over abstract justice and generosity, beauty, etc., and never to know these qualities when you meet them in the street, because there the circ.u.mstances make them vulgar. Thus I read in the privately printed biography of an eminently rationalistic mind: "It was strange that with such admiration for beauty in the abstract, my brother had no enthusiasm for fine architecture, for beautiful painting, or for flowers." And in almost the last philosophic work I have read, I find such pa.s.sages as the following: "Justice is ideal, solely ideal. Reason conceives that it ought to exist, but experience shows that it can- not. ... Truth, which ought to be, cannot be. ... Reason is deformed by experience. As soon as reason enters experience, it becomes contrary to reason."
The rationalist"s fallacy here is exactly like the sentimentalist"s.
Both extract a quality from the muddy particulars of experience, and find it so pure when extracted that they contrast it with each and all its muddy instances as an opposite and higher nature. All the while it is THEIR nature. It is the nature of truths to be validated, verified. It pays for our ideas to be validated. Our obligation to seek truth is part of our general obligation to do what pays. The payments true ideas bring are the sole why of our duty to follow them.
Identical whys exist in the case of wealth and health. Truth makes no other kind of claim and imposes no other kind of ought than health and wealth do. All these claims are conditional; the concrete benefits we gain are what we mean by calling the pursuit a duty. In the case of truth, untrue beliefs work as perniciously in the long run as true beliefs work beneficially. Talking abstractly, the quality "true" may thus be said to grow absolutely precious, and the quality "untrue" absolutely d.a.m.nable: the one may be called good, the other bad, unconditionally. We ought to think the true, we ought to shun the false, imperatively.
But if we treat all this abstraction literally and oppose it to its mother soil in experience, see what a preposterous position we work ourselves into.
We cannot then take a step forward in our actual thinking. When shall I acknowledge this truth and when that? Shall the acknowledgment be loud?--or silent? If sometimes loud, sometimes silent, which NOW? When may a truth go into cold-storage in the encyclopedia? and when shall it come out for battle? Must I constantly be repeating the truth "twice two are four" because of its eternal claim on recognition? or is it sometimes irrelevant?
Must my thoughts dwell night and day on my personal sins and blemishes, because I truly have them?--or may I sink and ignore them in order to be a decent social unit, and not a ma.s.s of morbid melancholy and apology?
