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.

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.

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

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

I suddenly stopped and looked out at the sea and thought, my God, how beautiful this is ... for 26 years I had never really looked at it before.

It is time, therefore, to abandon the superstition that natural science cannot be regarded as logically respectable until philosophers have solved the problem of induction. The problem of induction is, roughly speaking, the problem of finding a way to prove that certain empirical generalizations which are derived from past experience will hold good also in the future.

In other words, the propositions of philosophy are not factual, but linguistic in character - that is, they do not describe the behaviour of physical, or even mental, objects; they express definitions, or the formal consequences of definitions. Accordingly we may say that philosophy is a department of logic. For we will see that the characteristic mark of a purely logical enquiry, is that it is concerned with the formal consequences of our definitions and not with questions of empirical fact.
