Aspects of Mind contains previously unpublished manuscript material by Gilbert Ryle along with notes taken by the editor, Rene Meyer, at lectures given by Ryle on the philosophy of mind in 1964. Gilbert Ryle, Waynflete Professor of Metaphysical Philosophy at the University of Oxford from 1945 until 1967, had a decisive influence on contemporary philosophy. His Concept of Mind (1949) not only put a methodological edge in a most readable way to what has become known as Analytical Philosophy, but it also stimulated interest in the philosophy of mind as a pivotal part of philosophy as a whole. A second important influence derives from his reorganization of philosophical studies at Oxford after the war which made it, for several years, one of the liveliest philosophical centres in the world. Ryle's interest covered almost the entire field of philosophy. He also made substantial contributions to the history of philosophy, notably on Plato, Locke, Hume, Husserl and Heidegger. Gilbert Ryle died in October 1976. The book also includes two tributes to Ryle; one from John Mabbott, a close friend, on Ryle the man, and one from David Gallop, an ex-student, on Ryle the Philosopher. A chapter entitled "Philosophy, Logical Geography and Dilemmas" by Rene Meyer provides a perspective on Ryle's philosophy.
