There is philosophy, which is about conceptual analysis — about the meaning of what we say — and there is all of this ... all of life.
Emphasizing his views on philosophy as something abstract and separate from normal life to Isaiah Berlin, in the early 1930s, as quoted in A.J. Ayer: A Life (1999) by Ben Rogers, p. 2
No moral system can rest solely on authority.Alfred Jules Ayer
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.Alfred Jules Ayer
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.Alfred Jules Ayer
It seems that I have spent my entire time trying to make life more rational and that it was all wasted effort.Alfred Jules Ayer
I saw a Divine Being. I'm afraid I'm going to have to revise all my various books and opinions.Alfred Jules Ayer
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.Alfred Jules Ayer
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.Alfred Jules Ayer
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. There are only two ways of approaching this problem on the assumption that it is a genuine problem, and it is easy to see that neither of them can lead to its solution.Alfred Jules Ayer
The principles of logic and mathematics are true simply because we never allow them to be anything else. And the reason for this is that we cannot abandon them without contradicting ourselves, without sinning against the rules which govern the use of language, and so making our utterances self-stultifying. In other words, the truths of logic and mathematics are analytic propositions or tautologies.Alfred Jules Ayer
To say that authority, whether secular or religious, supplies no ground for morality is not to deny the obvious fact that it supplies a sanction.Alfred Jules Ayer
While moral rules may be propounded by authority the fact that these were so propounded would not validate them.Alfred Jules Ayer
Freddie became so much nicer after he died. He was not nearly so boastful. He took an interest in other people.Alfred Jules Ayer
The philosopher as an analyst is not concerned with the physical properties of things, but only with the way in which we speak about them.Alfred Jules Ayer
