What is the holy book for the agnostic religion?

Answer 1

Atheism is discussed in many books. However none of these are regarded as "holy" as that would require a god(s) to inspire the book. Atheism has as its only principle that there is no god(s). Atheism does not have any of the other attributes of a religion such as beliefs other than the absence for a god(s)), secret handshake, meeting halls, tax exemptions, salvation, miracles, prophets, a hierarchy, leaders, traditional costumes etc.

Answer 2

It depends what you're agnostic about. If you're agnostic about Christianity then, in a sense, The Bible would be your holy book.

But really, being agnostic simply means you can see, and are willing to admit, that the existence of the gods can be neither proven nor disproven. The word is formed by "a-", meaning without, and "-gnostic", meaning knowledge. So an agnostic is simply one without knowledge of the gods existence. It is not a religion, but rather a stance, or opinion, about religion. You can be an atheist, or a member of a religion, and still be an agnostic. In fact everyone is an agnostic, whether they realize it or not, because the existence of gods obviously cannot be proven.

Of course, what most people mean when they say they're agnostic, is that they haven't really formed an opinion on whatever it is that they've declared they're agnostic about.
