Some have supposed that morality has its basis in altruistic emotions implanted in accordance with the standard principles of natural selection. It is argued, to the contrary, that the falsity of group selection theory precludes founding genuine altruism on such a basis, and that the correct theory of evolution renders morality possible only if a cognitivist conception of moral psychology is accepted. Some independent reasons are given for favouring that conception over its noncognitivist rival. Morality is then claimed to be (...) a necessary corollary of advanced intelligence, so that morality cannot easily be selected against. Finally, the bearing of the foregoing considerations on the normative contention commonly labelled 'species-ism' is assessed; it is concluded that a proper view of morality suggests the inclusion of (other) animals within its domain of concern.

In the subsequent pages, I want to develop a distinction between wanting and valuing which will enable the familiar view of freedom to make sense of the notion of an unfree action. The contention will be that, in the case of actions that are unfree, the agent is unable to get what he most wants, or values, and this inability is due to his own "motivational system." In this case the obstruction to the action that he most wants to do (...) is his own will. It is in this respect that the action is unfree: the agent is obstructed in and by the very performance of the action. (shrink)
