Language is SpecialLanguage is Special

What is so special about language? Maybe nothing if you are a snail or a camphor tree. But language is paramount among the capacities that characterize humans, setting us off from even the most perfectly formed and functioning of the other beasts on earth; so, as a matter of species pride – if nothing else – we would hold up language as a marker of our humanity and thus a focus of our scientific interest. (Gleitman & Liberman 1991: xix)

Communication & Thinking “the private uses of language are equally

varied and important, including functions like problem-solving, enhancing social intelligence by rehearsing the thoughts of others, memory aids, focusing attention, etc. They seem to extend into almost every domain of thought.”

Spoken words are the symbols of mental experience and written words are the symbols of spoken words.

I have a notion that, when the mind is thinking, it is simply talking to itself, asking questions and answering them. … So I should describe thinking as a discourse,… not aloud to someone else, but silently to oneself.
