Abstract
Is acrasia possible? Can you do wrong knowingly? Opinion divides. Each, to the other side, is a paradox monger.At issue is the most felicitous set of concepts and principles to bring to descriptions and evaluations of human action. So to speak, such a set is an outline of a script for reality to play: it provides identities and relations in which individuals and events or whatever may be cast. Deniers typically begin with a set that rules acrasia out of court, recasting alleged examples in a different explanatory mold. Affirmers typically begin with plausible examples and look for a theoretical framework to place them in, taking those that disallow it to be absurd. But any denier, on legitimate dialectical grounds, can point out that such a reductio is a petitio. So it is a resilient issue, still with us after being bounced around so much in history.
