This was all in response to a comment by an atheist that I saw reposted on the pleaseconvinceme blog. But there was something else about that post that got me riled up. The original post said:
Theists imagine anything is possible simply because they have an imagination that can dream up anything they want. Atheists realize that isn't the case.What I find especially interesting about that statement is that I am actually frustrated by this tactic coming from the atheist camp, not the theist camp. This is especially obvious when you study the naturalistic theory of evolution as an explanation for everything. For example, one of the issues I noted last time was with the charge from atheists that the belief in God that runs rampant within our species is simply a product of evolutionary history. The thought is that, at a previous point in our species, the belief in a god or gods gave those believers some selective advantage. So now, even though that's not necessarily giving anyone a selective reproductive advantage anymore, it's something that has been imprinted in our species from our evolutionary history. That's actually become a working theory nowadays. The problem is there is zero evidence of this. It's an example of "as long as you can imagine it and it's consistent with naturalistic evolution, it's accepted as true".
Another example of this particular problem is where did our morals come from? Well, clearly (since there is no god), our morals do not come from a transcendent source. They must have been at one time given us an evolutionary advantage over the other humans who did not have those morals. Nowadays, since we are a "social species", morals are in place in our genes so that we contribute to the greater good of our whole species. The evidence for this is as abundant as for the above example. That is to say, it is completely absent. But it's an explanation that is consistent with the naturalistic evolutionary paradigm, so it's taken as a given now that someone thought of it.
Of course, the most classic example of, "as long as I can imagine it, it must be true" is Darwin's "warm little pond". In regards to theories of the origin of life, Darwin said in a famous letter to one of his colleagues that he could imagine a warm little pond where life got started. This idea alone gave rise to the entire hypothesis of a prebiotic soup that was supposedly present on the early earth, from which life arose. It wasn't long before this idea, for which there was zero evidentiary support, became scientific dogma. The idea of a prebiotic soup became so prevalent that nowadays everyone "knows" that's where life came from. Very, very interesting how these things happen.
