Quotes by A.J. Ayer
A.J. Ayer's insights on:
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.
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.
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.
I saw a Divine Being. I’m afraid I’m going to have to revise all my various books and opinions.
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 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.
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 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.
To make our position clearer, we may formulate it in another way. Let us call a proposition which records an actual or possible observation an experiential proposition. Then we may say that it is the mark of a genuine factual proposition, not that it should be equivalent to an experiential proposition, or any finite number of experiential propositions, but simply that some experiential propositions can be deduced from it in conjunction with certain other premises without being deducible from those other premises alone.
