- Well, I think that "answer" is completely lacking in explanatory value.
- Your parenthetical remark seems to hint at another explanation: that
- it is a matter of random chance, that there are (but why?) multiple
- universes with different laws, so many of them that life was bound to
- arise in some of them. Stronger forms of the anthropic principle
- (e.g., Barrow and Tipler's SAP and FAP) look like claims of backward
- causation--it is *because* of our observations that the world is the
- way it is. Regarding claims that strong, I have to agree with
- Martin Gardner's assessment that these are Completely Ridiculous
- Anthropic Principles, or CRAP.

- The point of the analogy was that there are two different questions
- to which we'd like an answer. The anthropic principle can only answer
- the less interesting one. (Why am I here? Because all the riflemen
- missed/because the conditions were right for life to arise. The more
- interesting question is why did all the rifleman miss/why were conditions
- right for life to arise? At some point the answer is probably going to
- have to be "it just did," but the anthropic principle looks like an
- attempt to disguise that fact and answer with "it just did" much
- earlier than necessary.)
