could be additionally brought forward to demonstrate that thought 
is one thing and language another, and that he might as well say 
that thought is gesticulation of all kinds, for language is, after all, 
only gesture of vocal parts. 
An important inference from this is that manual training would 
develop the symbolic field of the brain and afford a basis for 
mental development, where purely linguistic studies would tend 
to create inefficiency by crowding the speech center with symbols 
that are seldom used, comparable to the differences in education 
and usefulness that exist between the skilled mechanical engineer 
and the clownish contortionist.
