Agnosticism

Agnosticism is the belief that nothing is known or can be known of the existence or nature of God or of anything beyond material phenomena. My understanding of this term is based on the etymological breakdown and ancient use of the concept: "a-" as it relates to the alpha privative and "gnostic" as it relates to the concept of gnosis meaning insight or knowledge.

It is distinct from Atheism because Agnostics don't typically claim any knowledge affirming or denying the existence or nature of god, whereas Atheists tend to deny the existence of such a being.
