No God

Yes !

To be fair, he did not define atheism as such, but some vague glancing misrepresentation of cosmology and evolution/paleontology. In fact he failed to mention the single defining notion.

I would agree that the label is unnecessary if it were not for the sheer dominance and preeminence of religion. Atheism, for me, as a phrase should not really exist, we don't, after all, employ a unique phrase for people who don't believe in levitation or astrology or ghosts or water divination or telepathy or . . . (insert any number of magical / superstitious beliefs).

I certainly wouldn't define or describe myself as an 'a-theist' any more than I would describe myself as a 'a-astrologist'.
atheism shouldn't really be defined I used to (and still do) see it as simply not subscribing to organised religion but, as lucas said, people have a need to label things
