Terrence Deacon on the symbolic species - 0 views
language is not merely a mode of communication, it is also the outward expression of an unusual mode of thought—symbolic representation
[In] indexical association, [t]he word (iconically associated with past occurrences of similar utterances) and the object (iconically associated with past occurrences of similar utterances) and the object (iconically associated with similar objects from past experiences) and their past correlations enable the word to bring the object to mind .
[T]he major structural and functional innovations that make human brains capable of unprecedented mental feats evolved in response to the use of something as abstract and virtual as the use of words ... [T]he first use of symbolic reference by some distant ancestors changed how natural selection processes have affected hominid brain evolution ever since.

[S]ymbolic reference itself must have been the prime mover for the prefrontalization of the brain in hominid evolution. Language has given rise to a brain which is strongly biased to employ the one mode of associative learning that is most critical to it.
