Is Atheism Logically Untenable?

Must we keep an open mind about God, even those of us who are skeptical about the grounds for theism?

Let me first give some examples of things I personally do not feel I need to keep an open mind about. You may or may not agree:

I do not need to keep an open mind about whether it is possible for someone to predict events that will happen in my life by observing the movements of the planets and stars, or reading the lines on my palm.

I do not need to keep an open mind about the claims of Scientology.

I do not need to keep an open mind about Hitler's responsibility for the Holocaust.

Isn't it irrational of me to be dogmatic, when there are people who believe in astrology and palmistry, or in Scientology, or in Hitler's innocence? — Just because people believe something — perhaps lots of people — just because the available evidence does not logically rule out the possibility that their belief is true, is not in itself sufficient reason for suspending judgment. My argument is if you allowed that such considerations were sufficient for suspending judgment, "just think what the consequences would be."

When it comes to the question of the ultimate ground of our existence, we are all profoundly ignorant. All that is left is the practical decision — the existential choice — whether to live in fear of God. However, existential choice still leaves us with three possibilities: we can choose to embrace theism; we can postpone the choice and profess agnosticism; or we can choose to embrace atheism.

In these terms, I would argue, the atheist option is neither untenable nor illogical. What the atheist has and the agnostic lacks, is something akin to religious faith. For those who find such faith supporting and life enhancing, that is sufficient ground for belief.
