 Extensionality—Two Kinds of Cause

Show Summary Details


Mackie here considers the nature of the entities that are thought to stand in causal relations. The discussion focuses on the notion of the extensionality of these terms. Mackie distinguishes two types of cause—producing causes, which are related to events, and explanatory causes, which are related to facts. He then examines the question of the conditions under which it can be thought that equivalent descriptions of causal terms can be substituted, salva veritate. Mackie concludes that there is a difference regarding the extensionality of explanatory cause statements in that they are not interchangeable in the way that they might be in a regularity theory of causation.
