"Agnosticism is not some kind of weak-tea atheism," writes Ron Rosenbaum. "Agnosticism is not atheism or theism. It is radical skepticism, doubt in the possibility of certainty, opposition to the unwarranted certainties that atheism and theism offer. ... It's time for a new agnosticism, one that takes on the New Atheists. Indeed agnostics see atheism as "a theism"—as much a faith-based creed as the most orthodox of the religious variety."
