Neutral monism is the metaphysical view that the mental and the physical are two ways of organizing or describing the same elements, which are themselves "neutral", that is, neither physical nor mental. This view denies that the mental and the physical are two fundamentally different things. Rather, neutral monism claims the universe consists of only one kind of stuff, in the form of neutral elements that are in themselves neither mental nor physical; these neutral elements might have the properties of color and shape, just as we experience those properties, but these shaped and colored elements do not exist in a mind (considered as a substantial entity, whether dualistically or physicalistically); they exist on their own.
Some of the first views of the neutral monism position about the mind–body relationship in philosophy can be attributed to C. D. Broad. In one of Broad's early works—known simply as "Broad's famous list of 1925" (see chapter XIV of The Mind and Its Place in Nature)—he stated the basis of what this theory was to become. Indeed, no less than nine out of seventeen of his mind-body relationship theories are now classified as falling under the category of neutral monism. There are considerably few self-proclaimed neutral monists; most of the philosophers who are seen to have this view were classified after their deaths. Some examples of this are Baruch Spinoza, David Hume, Ernst Mach, Richard Avenarius, and Joseph Petzoldt.

"My thesis is," [James] says, "that if we start with the supposition that there is only one primal stuff or material in the world, a stuff of which everything is composed, and if we call that stuff 'pure experience,' then knowing can easily be explained as a particular sort of relation towards one another into which portions of pure experience may enter. The relation itself is a part of pure experience; one of its 'terms' becomes the subject or bearer of the knowledge, the knower, the other becomes the object known (p. 4)."
Russell summarizes this notion as follows:
James's view is that the raw material out of which the world is built up is not of two sorts, one matter and the other mind, but that it is arranged in different patterns by its inter-relations, and that some arrangements may be called mental, while others may be called physical.
Russell observes that the same view of "consciousness" is set forth in James's succeeding essay, "A World of Pure Experience" (ib., pp. 39-91). In addition to the role of James, Russell observes the role of two American Realists:
the American realists . . . Professor R. B. Perry of Harvard and Mr. Edwin B. Holt . . . have derived a strong impulsion from James, but have more interest than he had in logic and mathematics and the abstract part of philosophy. They speak of "neutral" entities as the stuff out of which both mind and matter are constructed. Thus Holt says: "... perhaps the least dangerous name is neutral-stuff."
Russell goes on to agree with James and in part with the "American realists":
My own belief – for which the reasons will appear in subsequent lectures – is that James is right in rejecting consciousness as an entity, and that the American realists are partly right, though not wholly, in considering that both mind and matter are composed of a neutral-stuff which, in isolation is neither mental nor material.
I do not think it is strictly accurate to say that rocks (for example) have experiences . . . although rocks may have experiences associated with them. ... Personally, I am much more confident of naturalistic dualism than I am of panpsychism. The latter issue seems to be very much open. But I hope to have said enough to show that we ought to take the possibility of some sort of panpsychism seriously: there seem to be no knockdown arguments against the view, and there are various positive reasons why one might embrace it. (Chalmers 1996:299)
The type-F view is admittedly speculative and it can sound strange at first hearing. Many find it extremely counterintuitive to suppose that fundamental physical systems have phenomenal properties: e.g. that there is something it is like to be an electron.
