As an example of someone who is willing to look stupid to deny science just because it bothers him ideologically, consider P. Z. Myers. He was aflutter over a piece in the New York Times that was concerned, in part, with fine-tuning. (And its close cousin, the weak Anthropic Principle, which is essentially what the multiverse proponents, in lieu of any experimental data, are invoking to explain the fine-tuning.) Myers wrote:
Alas, Davies also brings up the anthropic principle, that tiresome exercise in metaphysical masturbation that always flounders somewhere in the repellent ditch between narcissism and solipsism. When someone says that life would not exist if the laws of physics were just a little bit different, I have to wonder…how do they know? Just as there are many different combinations of amino acids that can make any particular enzyme, why can't there be many different combinations of physical laws that can yield life?
Which shows complete ignorance of the subject he attempts (with an epic FAIL) to criticize. He doesn't seem to grasp that if the constants are tweaked a bit there will be no elements to produce amino acids or any other molecules necessary for any kind of life.
Why is P.Z. so dumb? Because he can't grasp that fine-tuning is a metaphor. He is a afraid that it gives to much ammunition to the theists.
He reveals this when he doubles down on his stupidity:
I'm also always a bit disappointed with the statements of anthropic principle proponents for another reason. If these are the best and only laws that can give rise to intelligent life in the universe, why do they do such a lousy job of it?
1 My own position on climate change is this: I am a nuclear physicist. I have no expertise in the field of climate change. So just like any other scientific argument that is out of my field, and for which I have no time or interest to ramp up, I accept the scientific consensus. I have confidence that the checks and balances inherent in science mean that, when you don’t know and can’t evaluate on your own, it’s a good bet to accept the consensus view of in-field scientists. Or stay quiet.
5 The puddle argument (a sentient puddle observing just how perfect the universe (a pot hole) is for its existence, ergo god) is perhaps relevant for privileged planet debates (isn’t our planet just perfect for human life?) but not for cosmic fine-tuning which addresses the very building blocks (heavy elements) for any kind of life.
