It is now generally admitted, at any rate by philosophers, that the existence of a being having the attributes which define the god of any non-animistic religion cannot be demonstratively proved... [A]ll utterances about the nature of God are nonsensical.
~ A.j. Ayer
I do not believe in God. It seems to me that theists of all kinds have very largely failed to make their concept of a deity intelligible; and to the extent that they have made it intelligible, they have given us no reason to think that anything answers to it.
...His argument, as set out in The Problems of Philosophy, was based on the empirical fact that we are not only aware of things but are also, very frequently, aware of being aware of them.
