Gregory S. Kavka (1947-1994) on Consequentialism
Consequentialist moral theories evaluate acts or kinds of acts according to the value of the outcomes (i.e., actual or expected effects) of such acts. Utilitarian and egoistic variants of consequentialism differ in terms of how specified outcomes are valued. Egoistic theories evaluate outcomes in terms of the well-being or preferences of the acting agent. Utilitarian theories evaluate them in terms of the well-being or preferences of all affected individuals, with each person’s well-being or preferences being given equal weight. Thus, utilitarian and egoistic versions of consequentialism differ in their answers to the question “Consequences for whom?” Act and rule variants of consequentialism differ in terms of what outcomes (consequences) are evaluated. Act-consequentialist theories evaluate particular acts in terms of the value of their (actual or expected) outcomes. Rule-consequentialist theories evaluate types of actions (or rules requiring them) in terms of the (actual or expected) outcomes of certain agents performing, or trying to perform, acts of that type as a rule (i.e., the outcomes of the relevant agents following, or trying to follow, rules requiring acts of that type). Act and rule consequentialists differ in their answers to the question “Consequences of what?”

Note from KBJ: The two distinctions—utilitarian/egoistic and act/rule—cut across one another, creating four types of consequentialism: (1) Act-utilitarianism; (2) rule-utilitarianism; (3) act-egoism; and (4) rule-egoism. Kavka interprets Thomas Hobbes (1588-1679) as a rule-egoist.
Note 2 from KBJ: The first distinction—between utilitarian and egoistic—is not exhaustive. There are intermediate positions, such as tribalism and nationalism. The tribalist evaluates outcomes in terms of the well-being or preferences of all affected members of one’s tribe. The nationalist evaluates outcomes in terms of the well-being or preferences of all affected members of one’s nation. A better distinction is between impartialism and partialism. Utilitarianism is impartialism. Egoism is one type, but not the only type, of partialism.
Note 3 from KBJ: The second distinction—between act and rule—is not exhaustive, either. Any of a number of things can be evaluated in terms of their consequences: motives, acts, rules, even entire moral codes. A better distinction is between direct and indirect. Act-consequentialism is direct consequentialism. Rule-consequentialism is one type, but not the only type, of indirect consequentialism.
