Most of the imaging process is done without the use of the I-function; in fact the I-function usually has no control over our visual experience. If you examine the sensory “priorities” across cultures, you’ll see that there are commonalities within a culture, but not necessarily across cultures. There are certain visual, auditory and olfactory cues that we abide by, that other cultures my not. This can’t be a result of an individuals desire to conform to their culture because the I-function is not involved in many of the processes, such as imaging, that would cause them to perceive things in a different way. Nor can this be a result of natural selection which selects for favorable morphologies and not new structures and functions. Can culture, then, have a large enough affect on the brain so that there are profound similarities among its individuals, but not between those of other cultures? Could culture propel evolution of the human brain, where individuals can pass on the accumulated wisdom to their offspring? This is obviously just speculative conjecture, but it’s interesting to think about the factors that us so distinct, to the point where we experience different realities, and simultaneously very similar.
