I don’t see in what way How We See can be a problem for philosophy. It is a scientific problem to be investigated by the empirical methods of science. The philosopher, the poet, the artist, are concerned with the subjective experience. The only philosophically viable answer to the question about Where We See is, in my view, that it is in the totality where brain, eye, and world are one whole. The locus of experience is he Whole, and that is what is real for the philosopher as for the poet, not atoms or quarks or light rays or neurons or whatever reductionists want to trade our mind for.
