In this article I try to refute the so-called "libertarian" theory of free will, and to examine how our conclusion ought to modify our common attitudes of praise and blame. In attacking the libertarian view, I shall try to show that it cannot be consistently stated. That is, my dscussion will be an "analytic-philosophic" one. I shall neglect what I think is in practice an equally powerful method of attack on the libertarian: a challenge to state his theory in such (...) a way that it will fit in the modern biology and psychology, which are becoming increasingly physicalistic.
