The Mental and the Physical was first published in 1967. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. Professor Feigl's essay "The 'Mental' and the 'Physical'" has provoked a great deal of comment, criticism, and discussion since it first appeared as a part of the content of Volume II of the Minnesota Studies in the Philosophy of Science about ten years ago. Now Professor Feigl takes account of the critical discussions and presents his own comments with respect to the most important points raised in the criticisms. The essay itself is presented here in full, along with the postscript. The British Journal for the Philosophy of Science has called the essay "a 'super-colossal' survey of the mind-body problem." In its review of the earlier book containing the essay, Thought said: "This essay deserves careful reading by every philosopher concerned with genuine philosophical dialogue."
