“What do you see when you look at your face in the
mirror?” asks J. David Velleman in introducing his philosophical
theory of action. The face that you see is doing two things -- trying
to see itself and presenting itself to be seen. Velleman takes this
simple act of self-scrutiny as a model for the reflective reasoning of
rational agents: our efforts to understand our conduct are aided by
our reciprocal efforts to make it intelligible. He then argues that
this reflective reasoning is what constitutes practical reasoning, the
reasoning by which we figure out what to do. The thing to do, he
claims, is the thing that would make sense, in that it would be
intelligible. By applying this conception of practical reasoning,
Velleman develops philosophical accounts of intention, free will, and
the foundations of values and morals.
