Overwhelmingly, the most common defense of atheism is the (false) claim that atheism need not be defended at all. It is confidently stated that atheism is simply a “lack of belief in any gods”, as opposed to the belief that God does not exist. It is then said that one need not defend a simple lack of belief.
And, personally, I agree on that last point. A lack of belief need not be defended. But there are two very serious problems with the logic of this approach.
First is the reason why no defense is needed. It is not because atheism is somehow true by default. Rather, it is because (by this rather questionable definition) it is simply not a position at all. Anyone who isn’t claiming the non-existence of God, but simply lacks belief, isn’t advancing inquiry–or saying anything at all. Rather, this is simply an attempt to halt any attempt to discover what the truth might be.
Second is the fact that those who take this approach, just as much as the rest of us, have working answers to life’s big questions. Redefining atheism to mean “a lack of belief” doesn’t change this fact. Really, it simply insulates the atheist’s position from challenges.
Nearly always, the hidden position is materialism: the belief that matter and energy are all that exist. So, if the atheist wants to refute theism, he has to do more than attack theism (or, as is very often done, a horribly distorted straw man version of theism). We need a reason to think that materialism (or some other position) is more likely to be the case.
But, often as not, I encounter “refutations” of theism that would do as much damage to materialism. The “no evidence for God” argument is merely the prime example. While there is evidence for God, the point is that I’ve never encountered anyone who uses this (poor) argument that can offer evidence for materialism when asked for it.
As such, I hope it is becoming clear to more people why claiming to simply “lack belief” is (whether intentionally or unwittingly) an attempt to stack the deck in favor of the atheist. It halts inquiry instead of advancing it.
By all means, let us discuss whether or not it is more reasonable to think that God exists, or that the materialism of atheists popularizers is valid. But let’s examine both of these ideas, rather than pretending that the latter is somehow immune to being questioned or challenged.
That is, after all, just another form of dogmatism.
