ABSTRACT
1. I start from two pictures. One presents a view of what is involved when we ascribe propositional attitudes to one another. The other presents a view of what is involved when the scientist treats a human being as a physical thing – of what a neurophysiologist sees as going on when he concerns himself with the stimulations of sense organs, with the motor responses in a person’s body, and with events and states that intervene between such stimulations and responses.
