C. J. Ducasse

Ducasse was born in Angoul me, France. He obtained A. B. and A. M. degrees in philosophy from the University of Washington. In 1912, he obtained his Ph. D. from Harvard University. He is most notable for his work in the philosophy of mind and aesthetics. His influence can be seen in the work of Roderick Chisholm and Wilfrid Sellars. Ducasse was president of the Eastern division of the American Philosophical Association (1939-40) and the Philosophy of Science Association president. Ducasse wrote on parapsychology. He joined the American Society for Psychical Research in 1951 and served a term as vice president beginning in 1966. His book, A Critical Examination of the Belief in a Life After Death, is a philosophical attempt to examine the idea of life after death. In it, he expressed his belief in survival. Parapsychologists praised the book. Criticism came from philosopher Corliss Lamont, who asserted that some of the content was based on wishful thinking. Ducasse was a believer in reincarnation. Science writer Martin Gardner observed that Ducasse was notable for "combining nonbelief in God with a belief in the preexistence and the afterlife of human souls."

Originally published in 1969. This book examines the fundamental concepts of metaphysics and of theory of knowledge. Topics treated include the nature of substance and of causation; their relation to natural laws, dispositions, and attributes; the nature of consciousness and purposiveness; of symbols, signs, and signals, and their relation to interpretation and objective reference; and the nature and criteria of truth. The author holds that philosophy is by intent a science and that its becoming so requires precise and non-arbitrary semantical analysis of basic philosophical terms. He argues that philosophy then, like the other sciences, has practical importance: in its case this consists in its capacity to give to difficult practical decisions not only the efficacy insured by its application of the findings of the other sciences, but in addition some of the wisdom which is philosophy’s distinctive ultimate aim.
