rendering, and disciplined by the interaction of its social world, projects its content into that world again. In other words, the platform for all movement into the assertion of individual judgment—the level from which new experience is utilized—is already and always socialized; and it is just this movement that we find reflected in the actual results as the sense of the 'appropriateness' or synomic character of the meaning rendered.
"Now the development of thought, as we are to see in more detail, is by a method essentially of trial and error, of experimentation, of the use of meanings as worth more than they are as yet recognized to be worth. The individual must use his own thoughts, his established knowledges, his grounded judgments, for the embodiment of his new inventive constructions. He erects his thought as we say 'schematically'—in logic terms, 'problematically,' conditionally, disjunctively; projecting into the world an opinion still peculiar to himself, as if it were true. Thus all discovery proceeds. But this is, from the linguistic point of view, still to use the current language, still to work by meanings already embodied in social and conventional usage.
"Language grows, therefore, just as thought does, by never losing its synomic or dual reference; its meaning is both personal and social.
"It is the register of tradition, the record of racial conquest, the deposit of all the gains made by the genius of individuals . . . The social copy-system, thus established, reflects the judgmental processes of the race, and in turn becomes the training school of the judgment of new generations.
"Most of the training of the self, whereby the vagaries of personal reaction to fact and image are reduced to the basis of sound judgment, comes through the use of speech. When the child speaks, he lays before the world his suggestion for a general or common meaning. The reception he gets confirms or refutes him. In either case he is instructed. His next venture is now from a platform of knowledge on which the newer item is more nearly convertible into the common coin of effective intercourse. The point to notice here is not so much the exact mechanism of the exchange—secondary conversion—by which this gain is made,
