Agnosticism

From the Greek a (‘not’) and gnosis (‘know’).

In Philosophy of Religion it is the position which maintains that because of epistemic limitations we cannot know if God (i.e., as defined by Theism) exists or does not exist.

The agnostic maintains that both the atheist (who claims to know that God does not exist) and the theist (who claims to know that God does exist) are epistemically unjustified. The agnostic does not deny God's existence, she merely maintains that we have insufficient evidence to know God’s ontological status.
