Definition of "atheisms"

In short, our contention here is that theism is not only the affirmation of belief against non-belief, it is also the only rational presupposition against the two reductionist atheisms: materialism and humanism, and against the two inflated atheisms: pantheism and ultra-supernaturalism.
