- You're basing your conclusion on what you already know about firing squads.
- If you knew that only, say, one in ten individual shots would be expected
- to miss, and that many fewer than 10^15 firing squad executions have ever
- been performed, then, yes, you would certainly be justified in wondering
- whether there was something different about your case which let you survive.
- In contemplating the factors which allow life to exist in the universe,
- however, we don't know anything about how likely each shot will miss or how
- many trials there were. Suppose, in your example, that the number of
- people who face firing squads is unknown and potentially infinite. Then you
- would have no reason to think that your survival was anything special, or
- at least you couldn't claim that it was inexplicable in terms of what you
- knew.
-
- I'm not saying that the anthropic principle explains the existence of life,
- just that it says why life isn't inexplicable.
