No moral system can rest solely on authority.

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.

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 one takes full account of the persecution of heretics, the frequency and savagery of the religious wars which Christianity had endangered, the harm caused, especially to children, by the pernicious doctrine of original sin, a case could be made for saying that the world would have been better off without Christianity.

It seems that I have spent my entire life trying to make life more rational and that it was all wasted effort.

There is philosophy, which is about conceptual analysis - about the meaning of what we say - and there is all of this ... all of life.

I see philosophy as a fairly abstract activity, as concerned mainly with the analysis of criticism and concepts, and of course most usefully of scientific concepts.
