Logic and knowledge

This collection of John Mackie's papers on personal identity and topics in moral and political philosophy, some of which have not previously been published, deal with such issues as: multiple personality; the transcendental "I"; responsibility and language; aesthetic judgements; Sidgwick's pessimism; act-utiliarianism; right-based moral theories; cooperation, competition, and moral philosophy; universalization; rights, utility, and external costs; norms and dilemmas; Parfit's population paradox; and the combination of partially-ordered preferences.
