Abstract

To the proposition that I can know objects only from outside, and through the forms of sense and intellect that my personal equipment makes available, there is a single exception and that is my own body. Each of us is a physical object that knows one physical object from inside, namely itself. But I experience the movements of this body primarily as an agent rather than through organs of sense or intellect. My willed movements are perceived by others as matter in motion, but by me they are apprehended first and foremost as acts of will: the two are the same phenomenon experienced in different ways.
