(1) Only material exists within our "universe"1; (2) The uniformity of nature. Nature is uniform in time -- the regularity of the laws of nature, the same in the past, present and future2; (3) All states of the material universe are governed by material laws; (4) Humans are purely material systems produced by chance and the laws of matter (consequence of (1),(2) and (3)); (5) Therefore, humans are purely material; (6) Consequently, the mind and the material brain must be the same, or, rather, "mental" states are no more than particular material configurations (states) of the brain; (7) Therefore, all "mental" states are the results (effects) of material processes, and consequently, "thoughts" are effects and "epiphenomena" -- illusions with no causal agency;(8) However, humans are autonomous!It should be apparent to most that (8) is contrary to (1) through (7). However it is not apparent to those who are willing(!) adherents of the irrationality of "modern" thought, and nonetheless, believe in the existence of their amazing autonomous material mind!3
1 I put universe in quotes since the modern (atheist) view is that our observable universe is a detached quantum bubble -- the result of a quantum fluctuation in a larger "bulk" spacetime. Our "universe" is just one among a huge number of universes (multiverse theory). For the atheist, this larger "bulk" is considered eternal, uncreated and a brute fact. Regardless, the issue of minds within our "universe" is independent of that theory, as to the atheist only matter exists within our "universe."↩
2 The unifromity of nature (a phrase coined by Hume) is the principle that the laws of nature in operation today are the same as those in the past and also the future. The principle is basic to the notion of causation and the necessary presupposition for science "to work." It is foundational to the principle of scientific induction. An atheist that would deny the uniformity of nature would see his entire "scientific" worldview crash to the ground.↩
3 When the self-avowed material monist secretly believes (8) he is, in fact, an inconsistent crypto-dualist, cf. Van Til on the antitheses and An Atheist's Miracle.↩
