ABSTRACT
Popular metaphysics divides the known world into mind and matter, and a human being into soul and body. Some – the materialists – have said that matter alone is real and mind is an illusion. Many – the idealists in the technical sense, or mentalists, as Dr. Broad more appropriately calls them – have taken the opposite view, that mind alone is real and matter is an illusion. The view which I have suggested is that both mind and matter are structures composed of a more primitive stuff which is neither mental nor material. This view, called ‘neutral monism’, is suggested in Mach’s Analysis of Sensations, developed in William James’s Essays in Radical Empiricism, and advocated by John Dewey, as well as by Professor R. B. Perry and other American realists.
