The thing that characterizes Durkheim and his followers is their insistence upon the fact that all cultural materials, and expressions, including language, science, religion, public opinion, and law, since they are the products of social intercourse and social interaction, are bound to have an objective, public, and social character such as no product of an individual mind either has or can have. Durkheim speaks of these mental products, individual and social, as representations. The characteristic product of the individual mind is the percept, or, as Durkheim describes it, the "individual representation." The percept is, and remains, a private and an individual matter. No one can reproduce, or communicate to another, subjective impressions or the mental imagery in the concrete form in which they come to the individual himself. My neighbor may be able to read my "thoughts" and understand the motives that impel me to action better than I understand myself, but he cannot reproduce the images, with just the fringes of sense and feeling with which they come to my mind.
The characteristic product of a group of individuals, in their efforts to communicate is, on the other hand, something objective and understood, that is, a gesture, a sign, a symbol, a word, or a concept in which an experience or purpose that was private becomes public. This gesture, sign, symbol, concept, or representation in which a common object is not merely indicated, but in a sense created, Durkheim calls a "collective representation."
Dewey's description of what takes place in communication may be taken as a description of the process by which these collective representations come into existence. "To formulate an experience," as Dewey says, "requires getting outside of it, seeing it as another would see it, considering what points of contact it has with the life of another so that it may be gotten into such form that he can appreciate its meaning." The result of such a conscious effort to communicate an experience is to transform it. The experience, after it has been communicated, is not the same for either party to the communication. To publish or to give publicity to an event is to make of that event something other than it was before publication. Furthermore, the event as published is still something different from the event as reflected in the minds of the individuals to whom the publication is addressed.
