To the question "What is a human body?" I intend to propose seven preliminary answers: that it is an animal body with various powers of movement, some voluntary and directed; that it is a body whose movements afford expression to intentions and purposes that thereby possess a certain directedness; that, as an expressive body, it is interpretable by others and responsive to others; that, as an interpretable body, a variety of its characteristics are signs whose meanings others can understand; that its directedness has the unity of agency; that it cannot be adequately understood except in terms of the social contexts in which it engages with others and others with it; and that it is in certain respects enigmatic, a source of puzzlement, since alone among animal bodies it occasionally emits the question "What is a human body?" and directs its powers towards giving an answer to that question.
