[n]o Scientist Likes To Be Criticized. ... But You Don't Reply To Critics: "wait A Minute, Wait A Minute; This Is A Really Good Idea. I'm Very Fond Of It. It's Done You No Harm. Please Don't Attack It." That's Not The Way It Goes. The Hard But Just Rule Is That If The Ideas Don't Work, You Must Throw Them Away. Don't Waste Any Neurons On What Doesn't Work. Devote Those Neurons To New Ideas That Better Explain The Data. Valid Criticism Is Doing You A Favor.

You Could Just As Well Say That An Agnostic Is A Deeply Religious Person With At Least A Rudimentary Knowledge Of Human Fallibility.

The Cosmos Is All There Is, All There Ever Was, And All There Ever Will Be.
