Abstract

My aim in this paper is to initiate and contribute to debate concerning the possibility of behavior that is both self-defeating and self-governed. In the first section of the paper, I review a couple of points that figure in the literature as platitudes about (the relevant notion of) self-governance. In the second section, I explain how these points give rise to what seems to be a dilemma that suggests that informed self-defeating behavior, wherein one is aware of the consequences of each choice one makes, is impossible. In the third and fourth sections, I consider two types of cases that appear to be cases of informed self-defeating behavior and argue that one of the cases is a genuine case of self-defeating self-governance. I end with some remarks concerning self-governance, self-defeat, and dynamic choice. I suggest that the notion of self-defeat here employed provides a simple and compelling answer to the question “Are there any diachronic rationality constraints on agents?” The answer (or at least part of the answer) is “Yes, agents must avoid self-defeating behavior.” In section 5, I give reasons for thinking that all cases of diachronic irrationality are cases of self-defeating behavior in the relevant sense. As will become apparent, to the extent that the requirement to avoid self-defeating behavior calls for any cross-temporal coherence, it does so without endorsing a sort of conservatism that can interfere with personal growth and change.
