Philosophy, October 1974, contains an article entitled ‘Aristotle's Four Becauses’, by Professor Max Hocutt, who contends that Aristotle's aitia (or aition) means ‘a because’ or ‘an explanation’ rather than ‘a cause’ and should be translated accordingly. He argues (a) that only Aristotle's efficient ‘cause’ is a cause in the English sense of the word, and (b) that ‘Aristotle's theory of “causes” is simply an application of his theory of syllogistic to the analysis of scientific knowledge’ (p. 389). Both contentions deserve a word.
