Interests in both natural philosophy and political economy inform Allingham's (Oxford U.) effort to develop rational choice in a simple framework in which the problems of pure choice, choice under uncertainty, strategic choice, and social choice are unified. He also comments on some aspects of attitudes to risk as a digression on the second problem, and of the concept of knowledge as a digression on the third. His goal is not to treat the problems exhaustively but to identify the common thread that runs through them all. He uses symbolic logic but no real numbers or mathematical analysis. Annotation c.
