In: 1

Answer 1

Weak: we only think that the universe is fine tuned because it’s the one we are in; if the variables were different we wouldn’t exist to be questioning it. The universe is the way it is because if it wasn’t you wouldn’t exist to ask this.

Strong: the universe appears fine tuned because that tuning in some way promotes life capable of questioning it. You exist to ask this because the universe is the way it is.
