CHAPTER XVI

_INDUCTION AND EMOTION_

We have implied throughout that we have feeling about a thing only so

far as we attach on basis of past experience an experience value to the

thing, as we say, “the burnt child dreads the fire.” Induction, as this

interpretation is termed, is so important an element that we will devote

a little space to considering its _rationale_, development, and place in

intellectual emotion.

What is the _rationale_ of the inductive act? Why should iteration lead

to expectancy of reiteration? I observe that a body unsupported falls in

a hundred instances, but is it not arbitrary for me then to suppose that

it will fall the hundred and first instance? In fact would it not be

more rational to suppose that this particular combination should be

exhausted, that it was time for nature to stop? But this very reason

rests on the uniformity of nature—the very law we are questioning—as

experienced in the past and applied to the future; only it is a negative

law of omissions, literally law of reiteration of unreiterations. Thus

if reason takes the law of uniformity of nature to task it can only do

so by assuming it. J. S. Mill in his treatment of this matter (_Logic_,

bk. iii. chap. 3, sec. 2), falls into an error. It is, indeed, true, as

he says, that some occurrences repeated suggest cessation and not

recurrence, as when we have several consecutive cloudy days, we expect a

bright one, or having had several rainy seasons we expect a dry one; but

it is plainly wrong to regard this, as he does, as a contradiction of

the principle of uniformity of nature. On the contrary, this is a very

good example of it. Experience of intermittent character of bad weather

in the past leads to expectancy of its re-intermittency for the future,

and the oftener the experience the stronger the belief as to the nature

of the still unexperienced. A negative uniformity is as much a

uniformity as a positive.

It is plain that we can assign no reason for our belief in the

uniformity of nature. It is simply a fact, an arbitrary fact if you

will, that the more often experiences are conjoined, the more strongly

we expect the conjuncture. I may imagine a body unsupported remaining

stationary in the air as readily as to imagine it falling; however, I

_believe_ it will fall, and I duck my head for fear of getting hurt. Not

any speculative reason then, but a very practical reason, is at the

bottom of this inductive tendency, that is, the conservation and

progress of the organism is secured by induction as anticipatory

function. The origin of induction is not then in its abstract

rationality, but in its immediate utility as a life function. Experience

is self-adjustment through felt stimulus. Once begun it grows by

continual self-reference, and hence practically all experience is

inductive. Experience is thus a _continuum_, an integrating cumulating

whole; and inductive experience, like all experience, arises and

progresses by reason of its serviceability.

It has been implied that the inductive act arises very early in the

history of experience. Every psychosis is what it is by reason of all

the previous psychoses in the individual and the race. Psychism, while

it has its points of development in individuals, must yet be estimated

as a unit, as a single whole. But we have to ask whether this

modification of one psychosis by another is conscious or unconscious. If

some low organism have in its lifetime but two consciousnesses, must we

regard the second as influenced in quality by the first, and if so,

consciously influenced, that is, a conscious relating, an active

induction as opposed to mechanical integration? Is mind always

self-building, or does psychosis act and react on psychosis

automatically? We have maintained that all the growth of mind has been

in the past, as in the present, by struggle, by severest endeavour, and

hence if experience modify experience it is by conscious act. Experience

thus constantly connects with itself and builds upon itself, it is

self-integrating, that is, inductive, in all its evolution. Mind, as

primarily pleasure-pain and struggle, by endeavour reaches back to

itself, realizes itself, and rises upon itself.

Take a comparatively simple case. A child tastes an orange, and finds it

sweet, _i.e._, it relates the sweetness to the object, which relating is

a true thinking, an active conjoining or associating. Upon the

presentation of another orange to the child at a later date, he

identifies it as the sweet thing; he associates sweetness as to be

experienced from it on basis of past associating, that is, he makes an

induction. In this second orange-experience, as far as there is active

conjoining of mental products, a definite adding to present percept of

sweet taste as experienceable by conscious reference to former percept

(taste-experience), we must recognise a genuine thought-process. The

thinking consists in the joining of sensation of taste to an object, not

as a present, but as a future experience, on the basis of some past

experience. Here is a true mediation or reasoning of inductive type, and

also a true concept-process, that is, a taking together, a conscious

uniting, although the product is still particular. The nearest approach

to expressing this psychological process in language is to say, “This

round yellow is this sweet, because this round yellow was this sweet

before.” The correlating process rests upon the relating process

accomplished at first experience of orange-tasting, whereby the taste

was related to the thing tasted. This relating may be thrust upon the

mind, or the mind may consciously and actively assimilate. Thought in

the wide sense of the term may be made to include all mediate or

immediate conscious conjoining of experiences, whether the product be

general or particular.

Mediacy is certainly, however, accomplished before commonness is noted,

which in ordinary usage is concept-making. The grouping of the

particular taste with the particular sight and touch on basis of past

experience does not give a general result. The mediate term of past

experience of taste which the child brings up on sight of orange and

applies to the present case does not suggest commonness, but constancy

of experience, for at first it knows things only as identical, and not

as separate, or as like or unlike. The method of this early intelligence

is that of identifying, “The orange was sweet and is sweet”; and not

that of common characterizing, “Oranges are sweet, and this is an

orange.” The child does not discriminate or understand that the object

of its first experience is, by reason of this experience, no longer to

be experienced; it has not attained notion of disappearance. It does not

cognize the orange as one of a group or class, having as common

characters roundness, sweetness, and yellowness, and from presence of

round-yellow in any instance infer sweet; but it knows orange only as

this particular object of past, present, and future experience. Many of

the early thought-experiences of children are to be interpreted rather

upon this identity-method than upon the usual interpretation of true

concepts. Thus the child who calls every person of certain age, dress,

etc., “Papa,” is not thinking of a papa, or class of papas, but of the

papa. This is mistaken identity: the common and like is the same, and

the child requires considerable discrimination before it attains to

notion of papa in general. Same and not-same are discriminated before

like and unlike, and hence young children use common names as proper.

Now the mental product achieved by the child, which, as expressed in

words, we term the papa, may be styled a particular concept, a gathering

together of sight-sensations, and associating sound- and

touch-sensations with these so that any generally like group of

sight-sensations enables the child to call up on basis of past

experience the associated sound and touch, to expect the gentle word and

caress. The child in identifying the orange, “This round yellow thing is

the sweet thing,” is bringing together with a certain general force, not

of common characterization, indeed, but of temporal significance as

permanent grouping. Animals and young children think mostly on the

identifying plan; they join to and expect for a present experience what

has been conjoined with it in past experience, but the object is the

same, not a like one.

How then does the child come to knowledge of things as like, to form a

class of oranges after regarding all oranges as the orange? Pass oranges

before a young child one after the other so that one only is in sight,

and the child will probably know only one orange as the same continually

re-appearing. The image formed will, however, be more or less composite,

the mental product will be a concept-image, as being a re-inforcement

and exaggeration of common characters and a suppression of individual;

but for practical purposes it is still a particular concept, that is,

the child applies it to the one and not the many, and does not recognise

its representative nature. A general image as a group of common

qualities may be thus attained before consciousness of this generality

is reached.

If now two or three oranges are presented to the child at the same time,

it will learn to discriminate them as separate co-existences, having

characters in common, roundness, yellowness, etc.; the objects will be

recognised as individuals belonging to class round-yellow things. Here a

general image having a general import is achieved. The particular

characters, round, yellow, sweet, which always centred in and made up

the individual orange, are recognised to have general scope in applying

to many objects. Groups of characters had been achieved before by

particular thinking, but now by general thought groups of characters as

common are formed. From the practically coincident impressions it gains

the notion orange, so that it recognises new individuals as individuals,

and not as the individual or single object, as in the earlier and cruder

identity method of thinking. The mind now—instead of saying “Same

impressions, same object”—says “Same impressions, like objects.” Instead

of making an object as a group of qualities, it makes a class of objects

having the group of qualities in common. Concept-forming is thus often

but an extension from what I have termed the particular concept; the

group of qualities formed as characterizing the thing is through

experience with co-existences predicated of things. Notion or idea of

the orange precedes notion or idea of orange; but both are truly notions

or concepts, a taking together of impressions, one of particular, the

other of general import. The general significance of the particular

group is first forced upon the mind by experience, but soon the mind

generalizes as well as notices generalizations brought to it. Gradually

the mind obtains power to generalize, not only from co-existences, but

from successions, and later still to generalize by abstraction, to

compare and pick out common features amidst the unlike, to search for

unity in diversity.

The rise of generalizing power is through the struggle for existence; it

originates, like all other mental processes, in practical needs. Law is

thereby not simply acted upon or merely recognised, as in the

associative stage: it is definitely sought for and applied. Art arises,

and also science. The ability, given by generalizing power, of dealing

with things in the lump, becomes of signal service, and specially

distinguishes man. But the primary value of the concept in all its

stages is not as a summation of experience, but as a guide for the

future. Through reiterated grouping the concept-group is recognised as

permanent factor, so that one element of a group being given, other

elements are expected through a conscious assimilation with the past

experience. The concept answering to the word orange, for example, is

the mental product recognising a constant co-existence of certain

qualities of shape, colour, size, taste, etc., so that from occurrence

of one or more we infer other or others. Concepts are the inner

groupings, the mental synthesizings, which interpret the outer groupings

that we term laws of nature. In all this we see the inductive element in

its conscious form, experience developing itself by anticipating future

in terms of past.

We have now to consider briefly the psychological nature of judgment and

reasoning with special reference to the inductive feature. Logically

judgment is any connecting, _plus_ affirming of reality, as effected

through the copula. The copula is made, not only to denote relation, but

reality of relation, to express, not only the act of connecting, but

also its validity for the case in hand. Psychologically, judging may be

regarded as any thinking, as any relating without reference to the

things related, whether it be a joining of the concept “reality” to some

other concept as a concept-forming process, or any joining of other

elements. I have already discussed the nature of relating _per se_, but

on the topic of judgment a word is to be said about the

proposition-form. In all thinking there are the two things

joined—subject and predicate in language-expression—and the act of

joining, or copula in language-expression; thus all thought is capable

of the proposition-form. Indeed, the word-form cannot express a thinking

but only a thought as a consolidated and single product, and as a sign

of process. The word is a summary of process and relations, but it

cannot express process as concept-forming or judging. The word orange

signifies for the mind by symbolic and shorthand method, “Thing is sweet

_plus_ thing is yellow,” etc; but as far as process happens, and not

simultaneous composite representation, the process is capable of

proposition-form. All relatings or joinings, even of particulars to

particulars, are of the proposition-type, and I must dissent from the

common view that two percepts cannot stand in subject-predicate

relations. As I have before discussed, the relating of particular to

particular is thinking, and to say “This sweet belongs to this yellow”

is awkward indeed, but still psychologically proper. Every proposition,

on the other hand, is susceptible of analysis as expressive of

concept-forming relating. The proposition “Man is mortal” is expression

of a mental process of joining; the concept mortal is either attached to

or detached from the concept man, according as we consider the process

as synthetic or analytic. If it be a grouping or concept-forming in full

sense, it means that in forming the concept man, we add to the already

gathered qualities the quality “mortal” on basis of experience. The

child first notices deaths in cases of John, Peter, etc., whom it knows

to belong to the class “men,” forms the concept “mortal” and adds it by

generalisation to the whole class and enlarges concept “man” by one

quality. This proposition, as denoting inductive concept-forming,

expresses the act of incorporating on basis of experience the quality

mortal into the quality-group man. As analytic, as a detaching of what

has been grouped, the proposition still expresses joining, and until the

statement becomes purely formal and practically meaningless the

rejoining is always a strengthening of the concept, and formative in its

value.

All uniting or relating is, however, more than a bare connecting; it is

a definite mode of relating, it has a form; and the first and

fundamental form is that of time and space, by which all relating has

the inductive quality of relying upon the past for the interpretation of

the future. But thought as self-active mentality is specially stimulated

and controlled by the form of reality. All relatings are not, however,

influenced by sense of reality, and hence belief is not coincident with

judgment in the large sense. Affirmation or denial of actuality or

reality is a kind of joining, but is not joining _per se_. The infant

joins taste of sweetness with percept round-yellow for the first time

and for many following times with no reference to reality or unreality.

“This round-yellow is this sweet” expresses a mere connecting, a bare

relating, but as neither real nor unreal. There is no emphasis laid on

the copula by which it expresses more than a mere joining. But let the

perfect tranquility of the child’s experience be broken in upon by

discord of appearance and reality, let the child once have a bitter

experience with a round lemon, then its future conjoinings of

round-yellow and sweet will be more or less tinged by sense of

possibility of error, and emphasis will be laid on the copula, “That

_is_ sweet.” Through other such experiences with other of its

thought-groups, the child generalises to the universal significance of

reality and unreality for all its thinking; hence, all conjoinings with

their copula-expressions attain a new force and quality from this

induction. In the light of fallibility as making up a part of the

concept “experience,” all thought-experience modifies itself by this

self-relation. Reality becomes so constant and universal for all

thought-life that mature thought can never escape it. Hegel tried to

rise superior to the notion of existence, but psychologically, at least,

he failed. The conception or induction of reality becomes a necessary

form of thought by being united with all unitings. Judgment in the

narrow sense may be defined as all those relatings in which the reality

of the relation is affirmed or denied.

Lastly a word on the nature of reasoning. Reasoning is mediatorial; the

joining is accomplished through one or more mediates. Most if not all

thinking is by mediating; joining proceeds only upon ground or basis,

whether recognised or not as such. “Kings are mortal” is the

language-expression of a conjoining effected either through the

particular mediate term, John, or terms, John, Peter, etc., or through

the general mediate term men. In both cases the conjoining is effected

through subjoining of the mediate term to both the elements to be

conjoined. In the first case the process is: “John is mortal, John is

king, therefore kings are mortal.” This relating of king and mortal is

strengthened by subjoining for other particular mediates, Peter, James,

etc. In the second case the process is: “Men are mortal, kings are men,

therefore kings are mortal.” In both cases the appeal is to constancy of

coherence of a quality to a quality-group, in the first, mortality

coherent with king John, hence coherent with kings; in the second, kings

have mortality because mortality is coherent with the group man = kings

+ others. In both cases the generalising tendency, that is, the

inductive quality, is the main point and not the method of mediation. In

both processes the concept king is filled out by the additional quality

mortality, and there is real gain in generalising and concept-forming,

whether the mind accomplishes it by the more special or more general

reference. Induction in the large sense is thus inclusive of both

induction and deduction in the restricted sense as determined by the

mode of mediation. Inductive thinking, as we have treated it, is the

joining which generalises, whatever be the means used to this end.

Induction as generalising tendency is imbedded in experience, and is the

largest factor in all its development. All cognition as interpretation

is induction.

That induction, as giving the experience value of things on basis of

previous experience, is fundamental to all emotions about the things,

has been implied throughout our discussion. But the inductive act may

itself be emotively considered and intellectual emotion may arise. How

and why induction came to be a pleasurable act and carried on for its

own sake is, perhaps, not explainable by biologic evolution. It is

certain that the inductive act, like other functions, arises as painful

effort and as a mere means of serving life. Identifying and recognising

is accomplished only under pressure of the struggle for existence.

Animals in general, and, indeed, most human beings exercise their

intelligence, make inductions, only as compelled by the demands of life.

The Australian savages who guided Lumholtz in his search for new

marsupials knew about the animals solely in a practical way, and were

totally unable to comprehend Lumholtz’s motive. So geologists examining

stones are entirely misapprehended by savages and the semi-civilized,

though these people are sufficiently acquainted with stones so far as

they are a source of mineral wealth, are useful for building, etc. And

from the point of view of natural selection pure science, the pursuit of

knowledge solely for its own sake, without the least reference to its

appreciation, is unexplainable.

Nevertheless, it is a fact that at a certain point in psychism the

intellectual life develops for its own sake; the inductive act is

pleasurable, and the desire arises to continue it as such, that is, here

is true intellectual emotion, an emotion arising about an intellectual

act represented as such. This feeling about induction may rise to an

absorbing passion, as with Charles Darwin. He liked nothing better than

making inductions, until he finally came to like little else. If the

reason is asked for induction becoming pleasurable, and an end in itself

psychology at present has no answer.

It is plain that when intellectual activity is desired, not as a means,

but as an end in itself, it excludes much intellectual emotion which is

commonly associated therewith. Surprise and wonder, for instance, are

intellectual emotions at contemplating a conjuncture very contrary to

expectation, entirely opposite to some pre-formed induction, but they do

not imply devotion to intellectual activity as such. The visitor to a

biological laboratory who, on first seeing blood corpuscles, cries

“Wonderful! Who would have thought it! One’s blood all full of such

things! Let me look again!” is hardly actuated by the scientific motive.

All phenomena are equally wonderful or wonderless—which amounts to the

same thing—to the scientist; for him everything is simply natural, he

forms no expectations not founded on facts. The “wonders of science” are

wonders only to the outsider: the scientist takes them as matter of

fact. It is no more wonderful to him that the blood should be full of

corpuscles than that it should fall in drops. The tyro does not wonder

at a drop of blood; he wonders to see the drop filled with myriads of

animated corpuscles; the scientist wonders at neither. He who, on being

told of blood corpuscles, exclaims, “I want to know,” plainly desires

knowledge, but is not impelled by a pure thirst for knowledge. The

scientific items appearing in the newspapers generally appeal merely to

seekers for marvels and lovers of intellectual sensation. Surprise and

wonder are then extraneous impulses to knowledge, the impulse to

knowledge for its own sake being quite distinct. As based on

intellectual shock they imply a considerable intellectual integration,

and hence are by no means primitive in mental life, yet far from being

as late as emotion for knowledge _per se_. Wonder gives birth to the

Arabian Nights and to Jules Verne’s romances, but it always hinders true

science.

Again, the pleasure and desire of achieving and achievement often plays

a large part in intellectual pursuits, as in a wide variety of activity.

Reaching an end merely for the sake of accomplishment, an emotion about

any end, as, for instance, a wide generalisation to be attained, merely

as end, intellectual action has in common with all other teleological

action, but the teleologic emotion is not distinctly intellectual. The

desire to achieve for achievement’s sake, to reach the satisfaction of

accomplishment, is extremely multiplex in its application. The man who

does a thing just to see if he can do it, who does feats of any kind is

obviously impelled by a different emotion from the one who performs the

same activity for the pleasure of the activity itself. He who plays a

game to succeed, and he who plays for the pleasurable activity involved,

are in very different frames of mind. And emotion for achievement is

generally complicated by desire to be thereby superior to one’s fellows.

The intense competitive struggle is plain in all departments even among

scientists. The emotion of competition, the earnest desire to surpass

others in interpreting nature and life is a tremendous force among all

scientific workers, and not even Darwin himself, exceptional though he

was, could keep out every vestige of _amour propre_.

We note also that love of any intellectual activity for its own sake, as

induction, must be distinguished from the love of truth. Here induction

is exercised, not for itself, but as a means to an end, truth; inducing

is not merely a pleasing exercise, but a means to accomplishment of a

definite result. Darwin, of course, a trained and habitual inductionist,

worked both from the pleasurability of the activity and from his

devotion to truth, to which this induction was the true method. Though

both these motives, love of an activity and love of some definite end

thereby attained, as truth, reputation, etc., are closely connected,

they are perfectly distinct modes of emotion, as the least reflection

convinces. Truth is some very wide permanent and significant conjuncture

of experience discovered and set forth, such as the origin of species in

progressive modification, or the intensity of light in inverse

proportion to the square of the distance, and this is the kind of

induction or conjoining demanded by the love of truth.
