The idea of coercion is one that has played, and continues to play, at least two importantly distinct moral-theoretic roles in our thinking. One, which has been the focus of a number of recent influential treatments, is a primarily deontic role in which claims of coercion serve to indicate relatively weighty prima facie wrongs and excuses. The other, by contrast, is a primarily axiological or eudaimonic role in which claims of coercion serve to pick out instances of some distinctive kind (...) of pro tanto human bad (such as unfreedom or interpersonal subjection). I argue that this turns out not to be a simple case of one idea put to two different uses, but rather a case of two subtly distinct ideas in need of separate philosophical treatment. Moreover, although often relatively neglected, the primarily eudaimonic idea of coercion is of enduring importance to both liberal-perfectionist and socialist political moralities, as well as to personal ethics. This paper aims to elucidate it and to examine its relationship to its better-theorised deontic cousin. In addition, the paper seeks to show how a better understanding of these aspects of the concept can enable us to resolve certain important and long-standing theoretical disagreements, such as the dispute over whether coercion is an ‘essentially moralised’ concept and the dispute over whether (genuine) offers can be coercive.
