thinking

is thinking a function of language; if there was no language will we think? Is time a concept created by the brain? Analogy photo/cinema, are daily events which appear to move actually a series of still instances? colour is what the brain perceives; there are no colours in realty. Sound is waht the brain perceives; there are no sounds in realty. The Greek paradox of 'Will a tree falling in a forest make a noise if there is none to hear it?' vindicates this theory.
