    Note

    A coined word with a known birthday: Thomas Henry Huxley made it in 1869, either from Ancient Greek ágnōstos, "not knowing", or by putting a- in front of Gnostic. Either way the root is gignṓskō, "I know", so the word is about knowledge rather than belief. The agnostic position is that the question of God cannot be settled or proven, not that the answer is no.

    Note

    The noun has been explained again and again by those who wear it. Leslie Stephen's "An Agnostic's Apology" (1876) capitalizes it like the name of a sect. Bertrand Russell's "What is an Agnostic?" (1953) frames it as the impossibility of knowing. A character in Carl Sagan's Contact (1985) puts it most simply: the evidence isn't in.

Origin

Thomas Henry Huxley coined the word in 1869. His source was either ágnōstos, an Ancient Greek word meaning "ignorant, not knowing," or the combination of a- and Gnostic. Both routes lead back to the Greek prefix a- ("not") joined to gignṓskō ("I know").
