Abstract

P. T. Mackenzie's article is remarkable and challenging in several ways. It is, for instance, noteworthy that he reaches the surely correct conclusion that personal identity cannot be analysed in terms of memory without so much as entertaining Bishop Butler's terse and decisive objection to any such analysis: ‘… one should really think it self-evident that consciousness of personal identity presupposes, and therefore cannot constitute, personal identity; any more than knowledge, in any other case, can constitute truth, which it presupposes’.
