Abstract
Ockham is sometimes regarded as the chief source for a view of rights as arbitrary powers of radically isolated individuals. In fact he provides a quintessentially “reasonable” conception of natural or human rights, one which suggests a promising answer to the question of what such rights are, namely, capacities for reasonable activity. This view of personal rights is complemented by Ockham’s equally reasonable and suggestive account of what is naturally “right” for human communities in different human conditions. The unusual situation in which Ockham developed these ideas—as a theologian attacking the doctrinal pronouncements of a reigning pope—raises problems for extracting a systematic philosophical theory from his voluminous output, but the polemical setting of his political writings also gives them a certain relevance to current disputes about the place of secular thought in religious contexts.
