Abstract

THERE would appear to be no philosophical consensus about the nature of human action, even though discussion of that ancient topic has intensified in the last two decades. I shall nevertheless ask the reader to suppose that the question has at last been settled in its main lines, and settled in a way I shall describe in a moment. The supposition I have in mind is no light matter. The universe it envisions is radically different from what it would be if some other supposition were in its place. A detailed justification of it would require a thoroughgoing reassessment of many of the notions about causality that have prevailed in this century. Though I have offered something of that kind in earlier writings, the most I can hope to do here is to state the supposition in as brief, vivid, and concrete a way as I can manage. After that I shall ask what view of the rational agent it leads us to. No matter how action itself is interpreted, common sense attributes action to an agent. If the actions are those that take place in an atmosphere of rational discourse, it is natural to think of the agent as a rational one. Do we have any right to make this attribution in any way more exacting than that of common sense? Precisely what ontological status does the rational agent have? What, in particular, are we to make of its self-identity, seeing that some actions seem to modify the self-identity in which in a prima facie sense they originate?
