I have heard this argument before but have found it less than
convincing. The AP arguments, it seems to me, must be based upon an
implicit probability argument. Take the nuclear resonance found by
Hoyle which allowed carbon to be produced in stars. Why is this
resonance note-worthy? Because of all the other possible configurations
that COULD HAVE happened. Thus the fact that the precise value required
for life is what we find in our universe is considered evidence of a
finely tuned universe. The choice of one out of an innumerable plethora
of hostile possibilities is what makes the anthropic principle work.
Any comments?
