  A second reason for rejecting behaviorism is that some features of mentality—some elements, in particular, of the conscious mental life of persons—have characteristic ‘qualia’ or presentationally immediate or phenomenal qualities. To be in pain, for example, is not merely to produce appropriate pain behavior under the right environmental circumstances, but it is to experience a ‘like-thisness’ to the pain (as something dull or sharp, perhaps). A purely behaviorist creature, a ‘zombie’, as it were, may engage in pain behavior, including beneath the skin pain responses, yet completely lack whatever is qualitatively distinctive of and proper to pain (its painfulness).
