Atheism and Agnosticism

The main purpose of this article is to explore the differences between atheism and agnosticism, and the relations between them. The task is made more difficult because each of these words are what Wittgenstein called ‘family resemblance’ words. That is, we cannot expect to find a set of necessary and sufficient conditions for their use. Their use is appropriate if a fair number of the conditions are satisfied. Moreover even particular members of the families are often imprecise, and sometimes almost completely obscure. Sometimes a person who is really an atheist may describe herself, even passionately, as an agnostic because of unreasonable generalised philosophical scepticism which would preclude us from saying that we know anything whatever except perhaps the truths of mathematics and formal logic. continue
