As a philosopher, if I were speaking to a purely philosophic audience I should say that I ought to describe myself as an Agnostic,
because I do not think that there is a conclusive argument by which one can prove that there is not a God.
On the other hand, if I am to convey the right impression to the ordinary man in the street I think that I ought to say that I am an Atheist,
because, when I say that I cannot prove that there is not a God, I ought to add equally that I cannot prove that there are not the Homeric gods
