No matter how you care to define it, I do not identify with the local group. Planet, species, race, nation, state, religion, party, union, club, association, neighborhood improvement committee; I have no interest in any of it. I love and treasure individuals as I meet them, I loathe and despise the groups they identify with and belong to.
Atheism is not a philosophy; it is not even a view of the world; it is simply an admission of the obvious. In fact, 'atheism' is a term that should not even exist. No one needs to identify himself as a 'non-astrologer' or a 'non-alchemist.' We do not have words for people who doubt that Elvis is still alive or that aliens have traversed the galaxy only to molest ranchers and cattle. Atheism is nothing more than the noises reasonable people make in the presence of unjustified religious beliefs.
