No moral system can rest solely on authority.

Theism is so confused and the sentences in which "God" appears so incoherent and so incapable of verifiability or falsifiability that to speak of belief or unbelief, faith or unfaith, is logically impossible.

If the assertion that there is a god is nonsensical, then the atheist's assertion that there is no god is equally nonsensical, since it is only a significant proposition that can be significantly contradicted.

We shall maintain that no statement which refers to a 'reality'transcending the limits of all possible sense- experience can possibly have any literal significance.

We say that a sentence is factually significant to any given person, if, and only if, he knows how to verify the proposition which it purports to express.

It is possible to be a meta-physician without believing in a transcendent reality; for we shall see that many metaphysical utterances are due to the commission of logical errors, rather than to a conscious desire on the part of their authors to go beyond the limits of experience.

It appears, then, that ethics, as a branch of knowledge, is nothing more than a department of psychologyand sociology.
