habitudes are gradually assimilated to those of his group.

If we formulate the principle involved in this illustration, we
shall perceive that the social medium neither implants certain
desires and ideas directly, nor yet merely establishes certain
purely muscular habits of action, like "instinctively" winking or
dodging a blow. Setting up conditions which stimulate certain
visible and tangible ways of acting is the first step. Making
the individual a sharer or partner in the associated activity so
that he feels its success as his success, its failure as his
failure, is the completing step. As soon as he is possessed by
the emotional attitude of the group, he will be alert to
recognize the special ends at which it aims and the means
employed to secure success. His beliefs and ideas, in other
words, will take a form similar to those of others in the group.
He will also achieve pretty much the same stock of knowledge
since that knowledge is an ingredient of his habitual pursuits.

The importance of language in gaining knowledge is doubtless the
chief cause of the common notion that knowledge may be passed
directly from one to another. It almost seems as if all we have
to do to convey an idea into the mind of another is to convey a
sound into his ear. Thus imparting knowledge gets assimilated to
a purely physical process. But learning from language will be
found, when analyzed, to confirm the principle just laid down.
It would probably be admitted with little hesitation that a child
gets the idea of, say, a hat by using it as other persons do; by
covering the head with it, giving it to others to wear, having it
put on by others when going out, etc. But it may be asked how
this principle of shared activity applies to getting through
