But if the fundamental notions of science are of a religious origin, how has religion been able to bring them forth? At first sight, one does not see what relations there can be between religion and logic. Or, since the reality which religious thought expresses is society, the question can be stated in the following terms, which make the entire difficulty appear even better: what has been able to make social life so important a source for the logical life? It seems as though nothing could have predestined it to this rôle, for it certainly was not to satisfy their speculative needs that men associated themselves together.
Perhaps we shall be found over bold in attempting so complex a question here. To treat it as it should be treated, the sociological conditions of knowledge should be known much better than they actually are; we are only beginning to catch glimpses of some of them. However, the question is so grave, and so directly implied in all that has preceded, that we must make an effort not to leave it without an answer. Perhaps it is not impossible, even at present, to state some general principles which may at least aid in the solution.
Logical thought is made up of concepts. Seeking how society can have played a rôle in the genesis of logical thought thus reduces itself to seeking how it can have taken a part in the formation of concepts.
If, as is ordinarily the case, we see in the concept only a general idea, the problem appears insoluble. By his own power, the individual can compare his conceptions and images, disengage that which they have in common, and thus, in a word, generalize. Then it is hard to see why this generalization should be possible only in and through society. But, in the first place, it is inadmissible that logical thought is characterized only by the greater extension of the conceptions of which it is made up. If particular ideas have nothing logical about them, why should it be different with general ones? The general exists only in the particular; it is the particular simplified and impoverished. Then the first could have no virtues or privileges which the second has not. Inversely, if conceptual thought can be applied to the class, species or variety, howsoever restricted these may be, why can it not be extended to the individual, that is to say, to the limit towards which the conception tends, proportionately as its extension diminishes? As a matter of fact, there are many concepts which have only individuals as their object. In every sort of religion, gods are individualities distinct from each other; however, they are conceived, not perceived. Each people represents its historic or legendary heroes in fashions which vary with the time. Finally, every one of us forms an idea of the individuals with whom he comes in contact, of their character, of their appearance, their distinctive traits and their moral and physical temperaments: these notions, too, are real concepts. It is true that in general they are formed crudely enough; but even among scientific concepts, are there a great many that are perfectly adequate for their object? In this direction, there are only differences of degree between them.
Therefore the concept must be defined by other characteristics. It is opposed to sensual representations of every order—sensations, perceptions or images—by the following properties.
Sensual representations are in a perpetual flux; they come after each other like the waves of a river, and even during the time that they last, they do not remain the same thing. Each of them is an integral part of the precise instant when it takes place. We are never sure of again finding a perception such as we experienced it the first time; for if the thing perceived has not changed, it is we who are no longer the same. On the contrary, the concept is, as it were, outside of time and change; it is in the depths below all this agitation; it might be said that it is in a different portion of the mind, which is serener and calmer. It does not move of itself, by an internal and spontaneous evolution, but, on the contrary, it resists change. It is a manner of thinking that, at every moment of time, is fixed and crystallized.[1308] In so far as it is what it ought to be, it is immutable. If it changes, it is not because it is its nature to do so, but because we have discovered some imperfection in it; it is because it had to be rectified. The system of concepts with which we think in everyday life is that expressed by the vocabulary of our mother tongue; for every word translates a concept. Now language is something fixed; it changes but very slowly, and consequently it is the same with the conceptual system which it expresses. The scholar finds himself in the same situation in regard to the special terminology employed by the science to which he has consecrated himself, and hence in regard to the special scheme of concepts to which this terminology corresponds. It is true that he can make innovations, but these are always a sort of violence done to the established ways of thinking.
And at the same time that it is relatively immutable, the concept is universal, or at least capable of becoming so. A concept is not my concept; I hold it in common with other men, or, in any case, can communicate it to them. It is impossible for me to make a sensation pass from my consciousness into that of another; it holds closely to my organism and personality and cannot be detached from them. All that I can do is to invite others to place themselves before the same object as myself and to leave themselves to its action. On the other hand, conversation and all intellectual communication between men is an exchange of concepts. The concept is an essentially impersonal representation; it is through it that human intelligences communicate.[1309]
The nature of the concept, thus defined, bespeaks its origin. If it is common to all, it is the work of the community. Since it bears the mark of no particular mind, it is clear that it was elaborated by a unique intelligence, where all others meet each other, and after a fashion, come to nourish themselves. If it has more stability than sensations or images, it is because the collective representations are more stable than the individual ones; for while an individual is conscious even of the slight changes which take place in his environment, only events of a greater gravity can succeed in affecting the mental status of a society. Every time that we are in the presence of a type[1310] of thought or action which is imposed uniformly upon particular wills or intelligences, this pressure exercised over the individual betrays the intervention of the group. Also, as we have already said, the concepts with which we ordinarily think are those of our vocabulary. Now it is unquestionable that language, and consequently the system of concepts which it translates, is the product of a collective elaboration. What it expresses is the manner in which society as a whole represents the facts of experience. The ideas which correspond to the diverse elements of language are thus collective representations.
Even their contents bear witness to the same fact. In fact, there are scarcely any words among those which we usually employ whose meaning does not pass, to a greater or less extent, the limits of our personal experience. Very frequently a term expresses things which we have never perceived or experiences which we have never had or of which we have never been the witnesses. Even when we know some of the objects which it concerns, it is only as particular examples that they serve to illustrate the idea which they would never have been able to form by themselves. Thus there is a great deal of knowledge condensed in the word which I never collected, and which is not individual; it even surpasses me to such an extent that I cannot even completely appropriate all its results. Which of us knows all the words of the language he speaks and the entire signification of each?
This remark enables us to determine the sense in which we mean to say that concepts are collective representations. If they belong to a whole social group, it is not because they represent the average of the corresponding individual representations; for in that case they would be poorer than the latter in intellectual content, while, as a matter of fact, they contain much that surpasses the knowledge of the average individual. They are not abstractions which have a reality only in particular consciousnesses, but they are as concrete representations as an individual could form of his own personal environment: they correspond to the way in which this very special being, society, considers the things of its own proper experience. If, as a matter of fact, the concepts are nearly always general ideas, and if they express categories and classes rather than particular objects, it is because the unique and variable characteristics of things interest society but rarely; because of its very extent, it can scarcely be affected by more than their general and permanent qualities. Therefore it is to this aspect of affairs that it gives its attention: it is a part of its nature to see things in large and under the aspect which they ordinarily have. But this generality is not necessary for them, and, in any case, even when these representations have the generic character which they ordinarily have, they are the work of society and are enriched by its experience.
