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. The collective consciousness is the highest form of the psychic life, since it is the consciousness of the consciousnesses. Being placed outside of and above individual and local contingencies, it sees things only in their permanent and essential aspects, which it crystallizes into communicable ideas. At the same time that it sees from above, it sees farther; at every moment of time, it embraces all known reality; that is why it alone can furnish the mind with the molds which are applicable to the totality of things and which make it possible to think of them. It does not create these molds artificially; it finds them within itself; it does nothing but become conscious of them. They translate the ways of being which are found in all the stages of reality but which appear in their full clarity only at the summit, because the extreme complexity of the psychic life which passes there necessitates a greater development of consciousness. Collective representations also contain subjective elements, and these must be progressively rooted out if we are to approach reality more closely. But howsoever crude these may have been at the beginning, the fact remains that with them the germ of a new mentality was given, to which the individual could never have raised himself by his own efforts; by them the way was opened to a stable, impersonal and organized thought which then had nothing to do except to develop its nature.
