Abstract

For liberal political philosophers the notion of ?reasonableness? has provided a moral and legal standard for judging the acceptability and, by extension, legitimacy of government behaviour. In order for a government directive to constitute a legitimate obligation on citizens, it must be compatible with the dictates of reason and treat all citizens in a reasonable manner. Arguably, such an approach achieves its most powerful presentation (to date, at least) in the theories of ?political? liberals, who typically assert that reasonableness must be the ?final court of appeal? in relation to decisions concerning matters of public import ? i.e., those that place demands upon all citizens of the polity. According to political liberals, only by adopting and maintaining a governance framework that assigns primacy to reasonableness is it possible to obtain and preserve the desired protection against the abuse of political power. The purpose of this essay is to offer a brief review of the ?reasonableness? paradigm promoted by political liberals (in particular), and in the course of doing so, identify and assess a number of difficulties that would seem to undermine its ability to achieve its stated goal
