From what i could gather so far about anthropic principle is as follows:

The idea that we must observe that the universe contains properties compatible with the existence of an observer because if it did not, no one would be here to observe it, is called the anthropic principle or the Weak Anthropic Principle (WAP). The WAP is significant in that it makes the improbability of any one universe (i.e. our own) irrelevant. We should expect that our universe has features compatible with our existence, since, after all, we exist.

I understand the principle and am compatable with it. In fact I had implicitly assumed it. But the theory is not a restament of the principle but an attenpt to get at the properties of the univese.
