Quote:

agnostic noun. a person who believes that nothing is known or can be known of the existence or nature of God or of anything beyond material phenomena; a person who claims neither faith nor disbelief in God.

ORIGIN mid 19th cent.: from a- 1 [not] + gnostic



I am agnostic. But how did this word come about? Etymology-wise, it means I am not a believer in a prominent heretical movement of the 2nd-century.
