The idea that there is a distinct phenemenology of thought – that there is thinking experience just as there is visual experience or auditory experience – is a radical position in philosophy of mind. David Pitt is one of its foremost proponents. 

In The Quality of Thought (Oxford University Press, 2024), Pitt provides an extended defense of the position and its implications: if thinking is a kind of experience, then what about unconscious thought, or the idea that explaining thought must rely essentially and primarily on introspection? Pitt, who is a professor of philosophy at Cal State LA, also considers what the sui generis phenomenology of thought might be and explains how thought contents are determined purely internally, challenging today’s dominant views of content determination and the possibility of explaining thought content using naturalistic, non-introspection-based methods.
