Contemporary psychology has dealt with the problem of human agency in the terms and categories made available to it from its modernist heritage. Agency has been taken to be some capacity of essentially private minds to weigh alternatives and choose from among them. This paper argues that this conception ultimately fails since such weighing and choosing always require grounds that reach beyond private consciousness. An alternative conceptualization of agency as living truthfully is proposed. This concept of agency is exemplified and distinguished from "volition," which is much closer to the more traditional view of agency as the capacity to choose from among alternatives. Finally, the paper offers a grounding for agency in ethics, suggesting neither traditional notions, which are grounded in traditional metaphysics, nor postmodern notions, which accept ethical relativity, can render satisfactory accounts of human agency.
