The Possibility Theorem

Abstract

The sociological explanation of altruistic behaviour often encounters serious difficulties. This essay attempts to solve the altruism enigma through the presentation of an alternative explanation to Arrow’s Possibility Theorem as well as to Berlin’s serious objections to rational calculus in political behaviour. Bestowing charisma and/or sacredness to certain values often proves the solution to the puzzle by providing a rational criterion for action which cancels out other criteria and calculations. The Possibility Theorem which is put forward here solves the problem of the rationality of the supposedly irrational in rational choice situations and dilemmas. The Possibility Theorem is a contribution to the issue of the rationality of charisma and, therefore, to the analytical explanation of altruistic behaviour.
