These are excerpts and elaborations from my book "The Nature of Consciousness"
Monism There is an obvious
alternative to dualism: monism. According to monism, body and mind (matter and
thought) are made of the same substance: “idealists” think that everything is
mental, “materialists” think that everything is material. So monism mainly
divides into idealism and materialism. But the "one"
substance that everything is made of can also be something else than matter or
mind. The Dutch philosopher Baruch
Spinoza (17th century), for
example, believed that only one substance exists, which is both infinite and
eternal, and that “the” substance is conscious and it has extension. This
substance is expressed in an infinite series of “modes”. Humans only perceive
two of those modes because we are equipped with only two attributes of that
substance, hence we see a world of minds and bodies. When we perceive modes
through the attribute of thought, we perceive ideas, and we perceive them
through the attribute of extension, we perceive objects. God is all that exists
(he is what is), there is nothing that is not God. The British philosopher
Bertrand Russell was also a monist of sort, because he believed that everything in
the universe is made of spacetime events which are neither mental nor physical.
His “neutral monism” reprises ideas from the Austrian physicist Ernst Mach and from the US psychologist
William James (“Does ‘Consciousness’Exist?”, 1904): there is a fundamental constitutent of the universe which is neither
mental nor physical but yields both the mental and the physical that we
observe. Back to the beginning of the chapter "Mind and Matter" | Back to the index of all chapters |
