If we are to solve the central problems in the philosophy of science, Paul Churchland argues, we must draw heavily on the resources of the emerging sciences of the mind-brain. A Neurocomputationial Perspective illustrates the fertility of the concepts and data drawn from the study of the brain and of artificial networks that model the brain. These concepts bring unexpected coherence to scattered issues in the philosophy of science, new solutions to old philosophical problems, and new possibilities for the enterprise of science itself. Paul M. Churchland is Professor of Philosophy and a member of the Cognitive Science Faculty at the University of California at San Diego.
