Philip Pettit (2001) has suggested that there are parallels between his republican account of freedom and Amartya Sen's (1970) account of freedom as decisive preference. In this paper, I discuss these parallels from a social-choice-theoretic perspective. I sketch a formalization of republican freedom and argue that republican freedom is formally very similar to freedom as defined in Sen's “minimal liberalism” condition. In consequence, the republican account of freedom is vulnerable to a version of Sen's liberal paradox, an inconsistency between universal (...) domain, freedom, and the weak Pareto principle. I argue that some standard escape routes from the liberal paradox – those via domain restriction – are not easily available to the republican. I suggest that republicans need to take seriously the challenge of the impossibility of a Paretian republican.

This article defends laws in the social sciences. Arguments against social laws are considered and rejected based on the "open" nature of social theory, the multiple realizability of social predicates, the macro and/or teleological nature of social laws, and the inadequacies of belief-desire psychology. The more serious problem that social laws are usually qualified ceteris paribus is then considered. How the natural sciences handle ceteris paribus laws is discussed and it is argued that such procedures are possible in the social (...) sciences. The article ends by arguing that at least some social research is roughly as well as confirmed as good work in evolutionary biology and ecology. (shrink)
