There are thus at least three well-characterized levels, stages or types

of thought about the world we live in, and the notions of one stage

have one kind of merit, those of another stage another kind. It is

impossible, however, to say that any stage as yet in sight is absolutely

more TRUE than any other. Common sense is the more CONSOLIDATED stage,

because it got its innings first, and made all language into its ally.

Whether it or science be the more AUGUST stage may be left to private

judgment. But neither consolidation nor augustness are decisive marks of

truth. If common sense were true, why should science have had to

brand the secondary qualities, to which our world owes all its living

interest, as false, and to invent an invisible world of points and

curves and mathematical equations instead? Why should it have needed

to transform causes and activities into laws of 'functional variation'?

Vainly did scholasticism, common sense's college-trained younger sister,

seek to stereotype the forms the human family had always talked with,

to make them definite and fix them for eternity. Substantial forms (in

other words our secondary qualities) hardly outlasted the year of our

Lord 1600. People were already tired of them then; and Galileo, and

Descartes, with his 'new philosophy,' gave them only a little later

their coup de grace.

But now if the new kinds of scientific 'thing,' the corpuscular and

etheric world, were essentially more 'true,' why should they have

excited so much criticism within the body of science itself? Scientific

logicians are saying on every hand that these entities and their

determinations, however definitely conceived, should not be held for

literally real. It is AS IF they existed; but in reality they are like

co-ordinates or logarithms, only artificial short-cuts for taking us

from one part to another of experience's flux. We can cipher fruitfully

with them; they serve us wonderfully; but we must not be their dupes.

There is no RINGING conclusion possible when we compare these types

of thinking, with a view to telling which is the more absolutely true.

Their naturalness, their intellectual economy, their fruitfulness for

practice, all start up as distinct tests of their veracity, and as a

result we get confused. Common sense is BETTER for one sphere of life,

science for another, philosophic criticism for a third; but whether

either be TRUER absolutely, Heaven only knows. Just now, if I understand

the matter rightly, we are witnessing a curious reversion to the

common-sense way of looking at physical nature, in the philosophy of

science favored by such men as Mach, Ostwald and Duhem. According to

these teachers no hypothesis is truer than any other in the sense of

being a more literal copy of reality. They are all but ways of talking

on our part, to be compared solely from the point of view of their USE.

The only literally true thing is REALITY; and the only reality we know

is, for these logicians, sensible reality, the flux of our sensations

and emotions as they pass. 'Energy' is the collective name (according

to Ostwald) for the sensations just as they present themselves (the

movement, heat, magnetic pull, or light, or whatever it may be) when

they are measured in certain ways. So measuring them, we are enabled

to describe the correlated changes which they show us, in formulas

matchless for their simplicity and fruitfulness for human use. They are

sovereign triumphs of economy in thought.

No one can fail to admire the 'energetic' philosophy. But the

hypersensible entities, the corpuscles and vibrations, hold their own

with most physicists and chemists, in spite of its appeal. It seems too

economical to be all-sufficient. Profusion, not economy, may after all

be reality's key-note.

I am dealing here with highly technical matters, hardly suitable for

popular lecturing, and in which my own competence is small. All the

better for my conclusion, however, which at this point is this. The

whole notion of truth, which naturally and without reflexion we assume

to mean the simple duplication by the mind of a ready-made and given

reality, proves hard to understand clearly. There is no simple test

available for adjudicating offhand between the divers types of thought

that claim to possess it. Common sense, common science or corpuscular

philosophy, ultra-critical science, or energetics, and critical or

idealistic philosophy, all seem insufficiently true in some regard and

leave some dissatisfaction. It is evident that the conflict of these so

widely differing systems obliges us to overhaul the very idea of truth,

for at present we have no definite notion of what the word may mean. I

shall face that task in my next lecture, and will add but a few words,

in finishing the present one.

There are only two points that I wish you to retain from the present

lecture. The first one relates to common sense. We have seen reason to

suspect it, to suspect that in spite of their being so venerable, of

their being so universally used and built into the very structure

of language, its categories may after all be only a collection of

extraordinarily successful hypotheses (historically discovered or

invented by single men, but gradually communicated, and used by

everybody) by which our forefathers have from time immemorial unified

and straightened the discontinuity of their immediate experiences,

and put themselves into an equilibrium with the surface of nature so

satisfactory for ordinary practical purposes that it certainly would

have lasted forever, but for the excessive intellectual vivacity of

Democritus, Archimedes, Galileo, Berkeley, and other excentric geniuses

whom the example of such men inflamed. Retain, I pray you, this

suspicion about common sense.

The other point is this. Ought not the existence of the various types of

thinking which we have reviewed, each so splendid for certain purposes,

yet all conflicting still, and neither one of them able to support a

claim of absolute veracity, to awaken a presumption favorable to the

pragmatistic view that all our theories are INSTRUMENTAL, are mental

modes of ADAPTATION to reality, rather than revelations or gnostic

answers to some divinely instituted world-enigma? I expressed this view

as clearly as I could in the second of these lectures. Certainly the

restlessness of the actual theoretic situation, the value for some

purposes of each thought-level, and the inability of either to expel the

others decisively, suggest this pragmatistic view, which I hope that the

next lectures may soon make entirely convincing. May there not after all

be a possible ambiguity in truth?

Lecture VI

Pragmatism's Conception of Truth

When Clerk Maxwell was a child it is written that he had a mania for

having everything explained to him, and that when people put him off

with vague verbal accounts of any phenomenon he would interrupt them

impatiently by saying, "Yes; but I want you to tell me the PARTICULAR GO

of it!" Had his question been about truth, only a pragmatist could

have told him the particular go of it. I believe that our contemporary

pragmatists, especially Messrs. Schiller and Dewey, have given the only

tenable account of this subject. It is a very ticklish subject, sending

subtle rootlets into all kinds of crannies, and hard to treat in the

sketchy way that alone befits a public lecture. But the Schiller-Dewey

view of truth has been so ferociously attacked by rationalistic

philosophers, and so abominably misunderstood, that here, if anywhere,

is the point where a clear and simple statement should be made.

I fully expect to see the pragmatist view of truth run through the

classic stages of a theory's career. First, you know, a new theory is

attacked as absurd; then it is admitted to be true, but obvious

and insignificant; finally it is seen to be so important that its

adversaries claim that they themselves discovered it. Our doctrine of

truth is at present in the first of these three stages, with symptoms

of the second stage having begun in certain quarters. I wish that this

lecture might help it beyond the first stage in the eyes of many of you.

Truth, as any dictionary will tell you, is a property of certain of our

ideas. It means their 'agreement,' as falsity means their disagreement,

with 'reality.' Pragmatists and intellectualists both accept this

definition as a matter of course. They begin to quarrel only after

the question is raised as to what may precisely be meant by the term

'agreement,' and what by the term 'reality,' when reality is taken as

something for our ideas to agree with.

In answering these questions the pragmatists are more analytic and

painstaking, the intellectualists more offhand and irreflective. The

popular notion is that a true idea must copy its reality. Like

other popular views, this one follows the analogy of the most usual

experience. Our true ideas of sensible things do indeed copy them. Shut

your eyes and think of yonder clock on the wall, and you get just such

a true picture or copy of its dial. But your idea of its 'works' (unless

you are a clock-maker) is much less of a copy, yet it passes muster, for

it in no way clashes with the reality. Even tho it should shrink to the

mere word 'works,' that word still serves you truly; and when you

speak of the 'time-keeping function' of the clock, or of its spring's

'elasticity,' it is hard to see exactly what your ideas can copy.

You perceive that there is a problem here. Where our ideas cannot copy

definitely their object, what does agreement with that object mean?

Some idealists seem to say that they are true whenever they are what

God means that we ought to think about that object. Others hold the

copy-view all through, and speak as if our ideas possessed truth just

in proportion as they approach to being copies of the Absolute's eternal

way of thinking.

These views, you see, invite pragmatistic discussion. But the great

assumption of the intellectualists is that truth means essentially

an inert static relation. When you've got your true idea of anything,

there's an end of the matter. You're in possession; you KNOW; you have

fulfilled your thinking destiny. You are where you ought to be mentally;

you have obeyed your categorical imperative; and nothing more need

follow on that climax of your rational destiny. Epistemologically you

are in stable equilibrium.

Pragmatism, on the other hand, asks its usual question. "Grant an idea

or belief to be true," it says, "what concrete difference will its being

true make in anyone's actual life? How will the truth be realized?

What experiences will be different from those which would obtain if

the belief were false? What, in short, is the truth's cash-value in

experiential terms?"

The moment pragmatism asks this question, it sees the answer: TRUE IDEAS

ARE THOSE THAT WE CAN ASSIMILATE, VALIDATE, CORROBORATE AND VERIFY.

FALSE IDEAS ARE THOSE THAT WE CANNOT. That is the practical difference

it makes to us to have true ideas; that, therefore, is the meaning of

truth, for it is all that truth is known-as.

This thesis is what I have to defend. The truth of an idea is not a

stagnant property inherent in it. Truth HAPPENS to an idea. It BECOMES

true, is MADE true by events. Its verity is in fact an event, a process:

the process namely of its verifying itself, its veri-FICATION. Its

validity is the process of its valid-ATION.

But what do the words verification and validation themselves

pragmatically mean? They again signify certain practical consequences of

the verified and validated idea. It is hard to find any one phrase

that characterizes these consequences better than the ordinary

agreement-formula--just such consequences being what we have in mind

whenever we say that our ideas 'agree' with reality. They lead us,

namely, through the acts and other ideas which they instigate, into or

up to, or towards, other parts of experience with which we feel all the

while-such feeling being among our potentialities--that the original

ideas remain in agreement. The connexions and transitions come to us

from point to point as being progressive, harmonious, satisfactory. This

function of agreeable leading is what we mean by an idea's verification.

Such an account is vague and it sounds at first quite trivial, but it

has results which it will take the rest of my hour to explain.

Let me begin by reminding you of the fact that the possession of true

thoughts means everywhere the possession of invaluable instruments

of action; and that our duty to gain truth, so far from being a

blank command from out of the blue, or a 'stunt' self-imposed by our

intellect, can account for itself by excellent practical reasons.

The importance to human life of having true beliefs about matters of

fact is a thing too notorious. We live in a world of realities that can

be infinitely useful or infinitely harmful. Ideas that tell us which

of them to expect count as the true ideas in all this primary sphere of

verification, and the pursuit of such ideas is a primary human duty. The

possession of truth, so far from being here an end in itself, is only a

preliminary means towards other vital satisfactions. If I am lost in

the woods and starved, and find what looks like a cow-path, it is of the

utmost importance that I should think of a human habitation at the end

of it, for if I do so and follow it, I save myself. The true thought

is useful here because the house which is its object is useful. The

practical value of true ideas is thus primarily derived from the

practical importance of their objects to us. Their objects are, indeed,

not important at all times. I may on another occasion have no use

for the house; and then my idea of it, however verifiable, will be

practically irrelevant, and had better remain latent. Yet since almost

any object may some day become temporarily important, the advantage of

having a general stock of extra truths, of ideas that shall be true of

merely possible situations, is obvious. We store such extra truths away

in our memories, and with the overflow we fill our books of reference.

Whenever such an extra truth becomes practically relevant to one of our

emergencies, it passes from cold-storage to do work in the world, and

our belief in it grows active. You can say of it then either that 'it

is useful because it is true' or that 'it is true because it is useful.'

Both these phrases mean exactly the same thing, namely that here is

an idea that gets fulfilled and can be verified. True is the name for

whatever idea starts the verification-process, useful is the name for

its completed function in experience. True ideas would never have been

singled out as such, would never have acquired a class-name, least of

all a name suggesting value, unless they had been useful from the outset

in this way.

From this simple cue pragmatism gets her general notion of truth as

something essentially bound up with the way in which one moment in our

experience may lead us towards other moments which it will be worth

while to have been led to. Primarily, and on the common-sense level, the

truth of a state of mind means this function of A LEADING THAT IS WORTH

WHILE. When a moment in our experience, of any kind whatever, inspires

us with a thought that is true, that means that sooner or later we dip

by that thought's guidance into the particulars of experience again and

make advantageous connexion with them. This is a vague enough statement,

but I beg you to retain it, for it is essential.

Our experience meanwhile is all shot through with regularities. One

bit of it can warn us to get ready for another bit, can 'intend' or

be 'significant of' that remoter object. The object's advent is the

significance's verification. Truth, in these cases, meaning nothing but

eventual verification, is manifestly incompatible with waywardness on

our part. Woe to him whose beliefs play fast and loose with the order

which realities follow in his experience: they will lead him nowhere or

else make false connexions.

By 'realities' or 'objects' here, we mean either things of common sense,

sensibly present, or else common-sense relations, such as dates, places,

distances, kinds, activities. Following our mental image of a house

along the cow-path, we actually come to see the house; we get the

image's full verification. SUCH SIMPLY AND FULLY VERIFIED LEADINGS ARE

CERTAINLY THE ORIGINALS AND PROTOTYPES OF THE TRUTH-PROCESS. Experience

offers indeed other forms of truth-process, but they are all conceivable

as being primary verifications arrested, multiplied or substituted one

for another.

Take, for instance, yonder object on the wall. You and I consider it to

be a 'clock,' altho no one of us has seen the hidden works that make it

one. We let our notion pass for true without attempting to verify. If

truths mean verification-process essentially, ought we then to call such

unverified truths as this abortive? No, for they form the overwhelmingly

large number of the truths we live by. Indirect as well as direct

verifications pass muster. Where circumstantial evidence is sufficient,

we can go without eye-witnessing. Just as we here assume Japan to exist

without ever having been there, because it WORKS to do so, everything we

know conspiring with the belief, and nothing interfering, so we assume

that thing to be a clock. We USE it as a clock, regulating the length

of our lecture by it. The verification of the assumption here means its

leading to no frustration or contradiction. VerifiABILITY of wheels and

weights and pendulum is as good as verification. For one truth-process

completed there are a million in our lives that function in this state

of nascency. They turn us TOWARDS direct verification; lead us into the

SURROUNDINGS of the objects they envisage; and then, if everything runs

on harmoniously, we are so sure that verification is possible that we

omit it, and are usually justified by all that happens.

Truth lives, in fact, for the most part on a credit system. Our

thoughts and beliefs 'pass,' so long as nothing challenges them, just as

bank-notes pass so long as nobody refuses them. But this all points to

direct face-to-face verifications somewhere, without which the fabric of

truth collapses like a financial system with no cash-basis whatever.

You accept my verification of one thing, I yours of another. We trade on

each other's truth. But beliefs verified concretely by SOMEBODY are the

posts of the whole superstructure.

Another great reason--beside economy of time--for waiving complete

verification in the usual business of life is that all things exist

in kinds and not singly. Our world is found once for all to have that

peculiarity. So that when we have once directly verified our ideas about

one specimen of a kind, we consider ourselves free to apply them to

other specimens without verification. A mind that habitually

discerns the kind of thing before it, and acts by the law of the

kind immediately, without pausing to verify, will be a 'true' mind

in ninety-nine out of a hundred emergencies, proved so by its conduct

fitting everything it meets, and getting no refutation.

INDIRECTLY OR ONLY POTENTIALLY VERIFYING PROCESSES MAY THUS BE TRUE AS

WELL AS FULL VERIFICATION-PROCESSES. They work as true processes would

work, give us the same advantages, and claim our recognition for the

same reasons. All this on the common-sense level of, matters of fact,

which we are alone considering.

But matters of fact are not our only stock in trade. RELATIONS AMONG

PURELY MENTAL IDEAS form another sphere where true and false beliefs

obtain, and here the beliefs are absolute, or unconditional. When they

are true they bear the name either of definitions or of principles. It

is either a principle or a definition that 1 and 1 make 2, that 2 and 1

make 3, and so on; that white differs less from gray than it does from

black; that when the cause begins to act the effect also commences. Such

propositions hold of all possible 'ones,' of all conceivable 'whites'

and 'grays' and 'causes.' The objects here are mental objects.

Their relations are perceptually obvious at a glance, and no

sense-verification is necessary. 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 classed 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 assets. The hundredth decimal of pi, the

ratio of the circumference 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.
