It seems likely that the principal software used in the human brain consists of words, metaphors, disguised metaphors, and linguistic structures in general. The Sapir-Whorf-Korzybski Hypothesis, in anthropology, holds that a change in language can alter our perception of the cosmos. A revision of language structure, in particular, can alter the brain as dramatically as a psychedelic. In our metaphor, if we change the software, the computer operates in a new way.
