Lockean Self-Ownership: Towards a Demolition

Self-ownership is the moral principle that one ought to be left free to do whatever one chooses so long as non-consenting other persons are not thereby harmed, in specified ways. The principle is foundational for one tradition of political liberalism running from Locke to Nozick. This paper aims first to clarify this principle, in part by contrasting it with a kindred principle of 'self-benefit', and secondly to develop its implications for justified private property ownership. These implications are more meagre than is usually supposed. The principle is indeterminate in ways that undermine its claim to adequacy. Finally, further reasons for rejecting the self- ownership principle are suggested.
