What is an agnostic?
Agnostic translates as: a (without) gnostic (knowledge) so it means “without knowledge.” A purely agnostic person does not think it is possible to know if a god exists or not and, thus, remains undecided.
What is an agnostic (weak) atheist?
Agnostic atheism is simply another name for the broadest conception of the word atheist. An agnostic atheist does not believe in a god yet does not claim to have knowledge of said god’s non-existence. A weak atheist’s disbelief is largely dependent on a lack of evidence for a god.
What is a gnostic (strong) atheist?
Strong atheism is a position that certain types of gods definitely do not exist. An atheist may be gnostic towards the non-existence of some types of gods yet an agnostic atheist towards other types of gods.
From http://www.strongatheism.net :
Strong Atheism is the proposition that we should not suspend
judgment about the non-existence of a god or gods. More extensively, it is a
positive position against theistic values, semantics and anti-materialism, a
rational inquiry in the nature of religious thought, a new way of thinking about
religious and spiritual issues.
What is an apatheist?
Apatheism is not having a belief in god and couldn't care less if a god exists or not.
