Philip Pettit

In order to vindicate rational-choice theory as a mode of explaining social patterns in general - social patterns beyond the narrow range of economic behaviour - we have to recognize the legitimacy of explaining the resilience of certain patterns of behaviour: that is, explaining, not necessarily why they emerged or have been sustained, but why they are robust and reliable. And once we allow the legitimacy of explaining resilience, then we can see how functionalist theory may also serve us well in social science; we lose the basis - the empty black box argumenton which the rational-choice critique of the theory has mostly been grounded

Hobbes made a distinctive contribution to the discussion of freedom on two fronts. He persuaded later, if not immediate, successors that it is only the exercise of a power of interference that reduces people’s freedom, not its (unexercised) existence - not even its existence in an arbitrary, unchecked form. Equally, he persuaded them that the exercise of a power of interference always reduces freedom in the same way, whether it occurs in a republican democracy, purportedly on a ‘non-arbitrary’ basis, or under a dictatorial, arbitrary regime. But the basis on which Hobbes maintained those two propositions was very different from any that successors would have found plausible. This article explores the idiosyncratic principles that led Hobbes to develop his influential point of view. Key Words: freedom • Hobbes • liberalism • libertarianism • liberty.
