Egnor: The Weak Anthropic Principle, which is widely held by atheists, is meaningless: Only in a universe that permits the existence of intelligent beings can intelligent beings exist — i.e., only a universe with intelligent beings can be a universe with intelligent beings. The Weak Anthropic Principle is a tautology. And a tautology is not an explanation. It’s merely a sentence in which the predicate is the same as the subject. It’s meaningless.
Ola Hössjer: According to the Weak Anthropic Principle, we should not be surprised to live in a universe that harbors life. But I should add that, in our paper, “Cosmological Tuning Fine or Coarse?,” we compute or give an upper bound for the probability of a randomly generated universe to have a certain constant of nature, ending up within its life-permitting interval. We take the Weak Anthropic Principle into account — and still we come up with small probabilities for certain constant of natures or certain ratios or constants of nature.
