:::::I'm not convinced on the "textbook agnosticism" statement, because there are many different versions of agnosticism. As I read it, the second definition supports a statement like: "I don't know or I don't care about the existence of deities, but I choose not to believe in them anyway." In contrast, an agnostic is more likely to say something like: "I don't have any proof of the existence or nonexistence of deities, so the question of belief seems moot."
