This volume collects together Russell's philosophical writings during the period from 1947-68. For about half of this period Russell worked steadily at philosophy but after the publication of My Philosophical Development in 1959 he retired from academic philosophy for the second time. After that date, only the occasional philosophical piece appeared, as he was preoccupied with political writings. In this volume there are a handful of papers dated later than 1959, and all of these were certainly written by Russell himself. This volume contains Russell's writings on diverse philosophical interests, including autobiographical and self-critical papers, critiques of other philosophers and his controversial opinions on Christianity.
