This paper responds to three critical essays on my book, The Significance of Free Will(Oxford, 1996) by Randolph Clarke, Istiyaque Haji and Alfred Mele (which essays appear in this issue and an earlier issue of this journal). This response first explains crucial features of the theory of free will of the book, including the notion of ultimate responsibility.The paper then answers objections of Haji and Mele that the occurrence of undetermined choices would be matters of luck or chance, and so (...) could not be responsible actions. It then responds to concerns of Clarke that indeterminism provides no greater degree of control for defenders of incompatibilist free will and to concerns Clarke has about the notions of "effort" and "willing" in the book. Finally, the paper addresses objections of Haji concerning Frankfurt type-examples and the relation of moral responsibility to the power to act otherwise, and it addresses a concern of Mele's about why we should want a free will that is incompatible with determinism.
