Quote

There never comes a point where a theory can be said to be true. The most that one can claim for any theory is that it has shared the successes of all its rivals and that it has passed at least one test which they have failed.

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.

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.

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.
A.J. Ayer
Image
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.

The ground for taking ignorance to be restrictive of freedom is that it causes people to make choices which they would not have made if they had seen what the realization of their choices involved.

But if science may be said to be blind without philosophy, it is true also that philosophy is virtually empty without science.

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.

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.

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

Why should you mind being wrong if someone can show you that you are?

While moral rules may be propounded by authority the fact that these were so propounded would not validate them.

Image
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.

I saw a Divine Being. I'm afraid I'm going to have to revise all my various books and opinions.

If 'god' is a metaphysical term, then it cannot be even probable that a god exists. For to say that 'God exists' is to make a metaphysical utterance which cannot be either true or false. And by the same criterion, no sentence which purports to describe the nature of a transcendent god can possess any literal significance.

The misfortunes which God is represented in the book of Job as allowing Satan to inflict on Job, merely to test his faith, are indications, if not of positive malevolence, at least of a suspicious and ruthless insecurity, which is characteristic more of a tyrant than of a wholly powerful and benevolent deity.

I take it, therefore, to be a fact, that one's existence ends with death. I think it possible to show how this fact can be emotionally acceptable.

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