Neutral Monism - William James

William James

William James propounded the notion in his essay "Does Consciousness Exist?" in 1904 (reprinted in Essays in Radical Empiricism in 1912).

"Some subset of these elements form individual minds: the subset of just the experiences that you have for the day, which are accordingly just so many neutral elements that follow upon one another, is your mind as it exists for that day. If instead you described the elements that would constitute the sensory experience of rock by the path, then those elements constitute that rock. They do so even if no one observes the rock. The neutral elements exist, and our minds are constituted by some subset of them, and that subset can also be seen to constitute a set of empirical observations of the objects in the world. All of this, however, is just a matter of grouping the neutral elements in one way or another, according to a physical or a psychological (mental) perspective."
