Feser's account of consciousness posits that some mental faculties are immaterial, distinguishing intellect from imagination and sensation. He argues that intellectual activity cannot be fully explained by material processes, asserting that this leads to a denial of the determinate content of thoughts. Feser critiques modern materialism for failing to account for qualitative features of consciousness, proposing a return to Aristotelian views to resolve the hard problem of consciousness.
