What's this absurdity which I've just stated? Why, they are simply among the logical implications of atheism, of the denial that there exists a Creator-God, and that we are his creations.
I've explained these truths at other times and places, at more or less length, but I think that this post (in this thread at the 'Gates of Vienna' blog) succinctly captures the argument, so I reproduce it here:
"... In closing, I would like to state, that as soon as [there] is proof that there is no God, then I will change my position. (As you noted, that is an unlikely occurence.)"
It's not only unlikely, it's impossible, for what is false cannot be proven true.
The reality of minds in a material world (thus, every human being who has ever existed) is proof that atheism is false. If atheism were indeed the truth about the nature of reality, then we would not -- because we could not -- exist. But we do exist. Therefore, atheism is not the truth about the nature of reality.
This is the general form of the argument to support the prior claim --
GIVEN the reality of the natural/physical/material world, IF atheism were indeed the truth about the nature of reality, THEN everything which exists and/or transpires must be wholely reducible, without remainder, to purely physical/material states and causes. [edit: But, since there exist entities and events in the world which are not wholly reducible, without remainder, to purely physical/material states and causes, then it is seen that the denial that 'God is' is a false proposition.]
The explanation/proof is as follows --
This "everything" (which exists and must be wholely reducible, without remainder, to purely physical/material states and causes) includes our minds and all the functions and capabilities of our minds -- including reason (and, really, not just the individual acts of reasoning that we all engage in, but big-r 'Reason').
Now, specifically with respect to reasoning, what inescapably follows from atheism is that it is impossible for anything existing in reality (that included us) to reason.
When an entity reasons, it chooses to move from one thought or concept to another based on (its understanding of) the content of the concepts and of the logical relationship between them.
But, IF atheism were indeed the truth about the nature of reality, THEN this movement from (what we call) thought to though (which activity or change-of-mental-state we call 'reasoning') *has* to be caused by, and must be wholely explicable in terms of, state-changes of matter. That is, it is not the content of, and logical relationship between, two thoughts which prompts a reasoning entity to move from the one thought to the other, but rather it is some change-of-state of some matter which determines that an entity "thinks" any particular "thought" when it does.
I leave it to the reader to dwell on the further implications.
This logical implication/consequence of atheism (the one I have explicated) directly denies what we all know to be true about the "cause" of all acts of reasoning. This logical implication/consequence of atheism states an absurdity, namely that we do not, and cannot, reason. Since the stated absurdity is a logical implication/consequence of atheism, therefore atheism is shown to be absurd. Which is to say, necessarily false.
Perhaps Gentle Reader will ask me whether I expect many (or even any) of those persons who call themselves 'atheists' and 'agnostics' to admit, based on this reasoning or any reasoning, that there exists, and that we can know that there exists, a Creator-God.
Gentle Reader always was a humorist!
What I expect is to be called greatly mistaken about the reasoning I've explicated. Or too stupid to see that it's incorrect. Or a liar for asserting it.
