Qualia

Qualia^[1] is a term philosophers use for bits of perception or subjective, conscious experience. It is in the field called the philosophy of psychology, or philosophy of mind.^[2]

Examples of qualia include the pain of a headache, the taste of wine, or the perceived redness of an evening sky. It is a separate bit of experience, different from thinking about propositions or stream of consciousness thought.^[3]

Daniel Dennett (born 1942), American philosopher and cognitive scientist, says qualia is "an unfamiliar term for something that could not be more familiar to each of us: the ways things seem to us".^[4]
