linguistic symbolism.

One word more as to the relation between language and thought. The point
of view that we have developed does not by any means preclude the
possibility of the growth of speech being in a high degree dependent on
the development of thought. We may assume that language arose
pre-rationally--just how and on what precise level of mental activity we
do not know--but we must not imagine that a highly developed system of
speech symbols worked itself out before the genesis of distinct concepts
and of thinking, the handling of concepts. We must rather imagine that
thought processes set in, as a kind of psychic overflow, almost at the
beginning of linguistic expression; further, that the concept, once
defined, necessarily reacted on the life of its linguistic symbol,
encouraging further linguistic growth. We see this complex process of
the interaction of language and thought actually taking place under our
eyes. The instrument makes possible the product, the product refines the
instrument. The birth of a new concept is invariably foreshadowed by a
more or less strained or extended use of old linguistic material; the
concept does not attain to individual and independent life until it has
found a distinctive linguistic embodiment. In most cases the new symbol
is but a thing wrought from linguistic material already in existence in
ways mapped out by crushingly despotic precedents. As soon as the word
is at hand, we instinctively feel, with something of a sigh of relief,
that the concept is ours for the handling. Not until we own the symbol
do we feel that we hold a key to the immediate knowledge or
understanding of the concept. Would we be so ready to die for "liberty,"
to struggle for "ideals," if the words themselves were not ringing
within us? And the word, as we know, is not only a key; it may also be a
fetter.
