Gnosis (From the Greek gnosis, to know): attribute of those who claim to know the truth about God and Divinity.
Agnosticism (-a, contrary of Gnosis): those who claim there's no way to proof or disproof or to understand deities.
The most simple description however to describe an Agnostic is "anti-Dogmatic" or skeptical.
Back on definitions:
Dogma: To accept a thing, without any solid evidence, as an incontestable truth.
Agnostics differs then to religious people because those ones believes and accepts as a Dogma the claimed miracles/supernatural stuff of their religion and its books.
Agnostics differs also from Atheists, because Atheists also believes Dogmatically that there's no God.
What is it to be confused here? An atheist who says is agnostic, then he's probably unsure whether God exists or not; to be atheist he must believe there's no God, or at least as Nietzsche on Also Sprach Zaratustra says "God is dead". |
