Cognitive science is an interdisciplinary study of the mind loosely united by the idea that the mind is a computer. Philosophy is one of the main contributing disciplines (along with psychology, neuroscience, linguistics, and computer science), and many of its contributions concern the conceptual foundations of the separate disciplines (e.g., psychology and artificial intelligence), explorations of the relations between the disciplines (e.g., is psychology reducible to neuroscience?), and examinations of core uniting ideas (e.g., how best can we understand the idea that the mind is a computer?). Much contemporary philosophy of cognitive science overlaps with contemporary philosophy of mind. The present work tries as much as possible to focus on work peculiar to the philosophy of cognitive science, but the reader is advised to see pertinent work discussed in other Oxford Bibliographies Online articles, especially Metaphysics of Mind and Consciousness.
