Here’s a tough bit of apologetic truth: Often times we give atheism too much credit. Too often we’ve allowed atheists to determine and dictate what is “rational.”
The problem of atheist rationality. Christians should not grant atheism a “get out of jail free” card. Atheism itself is not a rational position. The conversation is open and shut, in principle, if we allow (whether explicitly or implicitly) the atheist to determine rationality. Here’s a simple point, but one that’s worth noting: Atheists, when consistent, define rationality in accord with atheism. It’s all people interpret data (evidence, etc) in light of prior philosophical/religious commitments. So, what is “rational” for an atheist is determined by non-belief.
New atheists such as Daniel Dennett, Richard Dawkins, and Sam Harris may claim that rationality evolved. But at the end of the day their argumentation won’t fly. As others have argued, a justification for rationality that undermines trust in rationality is not rationality at all. According to the argument from reason, if Darwinian evolution is true, then most, if not all, of what we do and believe is directed toward survival, not truth. But if this is true— if we can be confident that that’s what driving our thinking— then what certainty do we have that we can trust our thinking? And if we have no rational for trusting our beliefs, then we don’t have any certainty that our thinking about anything is true, including our thinking about evolution. On an evolutionary account, our cognitive equipment is merely geared toward survival and procreation.
What I’m not saying. Now for clarification, lest I be misunderstood. This isn’t to say that all atheists are irrational. A great many atheists are brilliant and far more educated than Christians. Though this is exactly what we should expect if we read our Bibles (Cf. 1 Cor. 1-2, James 2). God chose the things that are reckoned low and of disrepute in order to ultimately demonstrate that “finding” him isn’t about our gifts, strengths, or achievements. Again, 1 Cor. 1 says that God structured his plan to save sinners in a such a way that “the world through its wisdom would not know Him.” So, if this is true (and it is), we shouldn’t expect thinking based on strictly atheistic assumptions to be the kind of thinking that recognizes the evidence for God in this world (at least not explicitly, cf. Rom. 1).
The apologetic point I’m making is not whether atheists are sane and healthy-minded people. The point I’m making is that so many of them are, and are so in spite of their worldview. Informing of this very worldview-disconnect is what I mean by not granting them more than atheism deserves. When modern naturalistic atheists acts as if their reason is trustworthy, then are thinking like a Christian, not an atheist.
Why? We all live our lives on the functional assumption that logic is real and objective. But what accounts for it? A Christian would say that at its root, the existence of the infinite-personal God of the Bible is the One that provides the preconditions to make the existence of objective logic standards intelligible. And unless someone can provide a workable philosophical account of the ontological existence of objective logical standards, they are the ones those philosophies disappear in a puff of smoke.
Worldview cohesion. We all have an ultimate commitment, or “centering belief,” that guides and directs the flow of our beliefs, desires, and hopes. Only when we find worldview harmony with our centering beliefs can we righted be called rational.
So, what about Christians? By the standard I’ve proposed, are we rational? Christians believe God is the creator of the universe and the ultimate reason why we can trust our sense perception of the outside world. God created both the world around me and my faculties of perception in such a fashion to be generally reliable. Our general trust in human rationality is grounded in our commitment to Christianity (just as our suspicions of human rationality are also rooted in our Christian doctrine of the noetic effects of sin).
Any view that denies this, while it may seem perfectly “rational” to the atheist, is completely foreign from my way of thinking and will be considered irrational to me. Am I being unnecessarily narrow? I don’t think so, after all, most atheists clearly believe that Christian belief is irrational when they characterize it as a fairy tale for adults.
