https://en.wikipedia.org/wiki/Agnosticism

According to the philosopher William L. Rowe: "In the popular sense of the term, an agnostic is someone who neither believes nor disbelieves in the existence of God, while a theist believes that God exists, an atheist disbelieves in God“

我认识的大部分科学家是agnostic，和atheist不完全相同（gcd应该归类于atheist）。
