ABSTRACT
A Introduction This paper is concerned with the ways in which a number of social theorists have used the notion of rationality to assess ocial choices. Each theorist advances one or more conditions as requirements of rationality in social choice, and considers a social choice to be acceptable and worthy of approval only if it satisfies such conditions. I shall examine some of the rationality requirements proposed, and ask why they should be taken as grounds for supporting or approving a social choice.
