So as to not misstate the author the following is two excerpts of his argument:
A creature that could not respond correctly to its environment, or that did so only imperfectly, would be at a significant survival disadvantage compared to one that could perceive more accurately. Therefore, it should be obvious that, all else being equal, evolution will always favor greater accuracy of sensory perception - both the ability to sense the environment with greater fidelity and the disposition to respond correctly to those sensory impressions.
Though it is not perfect, it is more than obvious that evolution will produce at least generally reliable mental tools for environmental perception, pattern recognition and abstract reasoning in any intelligent being. In light of this, the burden of proof is now on the presuppositionalists to explain why an evolutionary naturalist should not consider their own beliefs reliable.
If evolution is generating minds that think more and more truly then why do billions of people ascribe to religion and spiritual worship that atheists claim are illogical practices? If evolution is producing reasonable truth thinkers why are there so few atheists in this world? Are atheists claiming to be superior to the rest of the world? Atheism, despite the few popular books in the end caps at Barnes and Noble is not the wave of the future. Postmodernism is actually the current ebb and flow of the today’s world which does not ascribe to the knowablity of truth nor the supremacy of science and reason. Why is one more popular than the other if atheists are the more evolved humans? Most postmodern thinkers are very much into spiritualist thinking versus dogmatic reason. I’m not advocating postmodernism. I am only pointing out that it is fast becoming a cultural norm as modernism is quickly being transformed to postmodern thinking. Atheists are still behind the curve if we are truly looking at what is new and surviving as the most reliable human thought. So if evolution is producing true thinking as time marches on, why is culture moving away from science and reason to experience and spirituality?
If this explanation of evolutionary truth development were true then atheists would be the most ascribed to worldview instead of one of the least believed worldviews. It would appear that the argument for evolutionary establishment of truth in the human mind is actually self-defeating for atheists.
Author's Note: Please see comment exchanges to see that I was not understanding the nature of the argument I was addressing before I made this post. I am in dialog with those of the atheist worldview in the comments to learn more about what their position truly is so that I do not falsely represent it. I would delete this blog, but I would lose the comments and the lessons learned attached. So I invite my readers to read the comments for more on this topic.
