See, it worries about whether atheism is *proveable* and other stuff about proof. But fallibility tells us that certainty isn't possible (and that this isn't not an obstacle to knowledge or truth). What matters is what the best explantion of reality is, and that's what a discussion of the truth of atheism ought to focus on.
Note that "fallibility tells us" is no more than arguing in terms of high-level concepts; it is *not* any sort of appeal to the authority of the principle of fallibility, and *not* an unsupported assertion.
read a bit more. look at this "Within mechanistic atheism, you have people who think that atheism is somehow scientific and actually can be proved, and others who understand that atheism is a religious belief which is no more susceptible to actual proof than any other religious belief." *sigh*
and i should mention the focus on proof isn't the only manifestation of asking the wrong questions causing the piece to be mostly pointless. and also that it does have some truth in it anyway.
