“Freddie became so much nicer after he died. He was not nearly so boastful. He took an interest in other people.”

“He was undoubtedly one of the liveliest figures on the British philosophical scene in his time and, when he appeared on it, it was in need of enlivening. He was not a highly original thinker. His impact was due to the brilliance with which he arranged and expressed the ideas he had acquired from others. Perhaps his greatest intellectual virtue was his unremitting adherence to clarity and to rational argument. His work is without allusions, undeveloped suggestions, obscurity, and mannerism. Through his books and his teaching he sets a fine example of intellectual discipline.”

“He was the antithesis of the philosopher of mystery and intimation, and he was not tempted to technicality. He lived assertively and was vain and cocksure — at some cost to his philosophical reputation, since other philosophers were as human in their judgements on him. He was also honest, humane, and more or less on the Left in politics. He liked society, was a man of many women, came to be self-judging, and after some sadness died bravely, on 27 June 1989.”

“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.”

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

“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.”

“If now I…say "Stealing money is wrong," I produce a sentence which has no factual meaning — that is, expresses no proposition which can be either true or false. It is as if I had written "Stealing money!!" — where the shape and thickness of the exclamation marks show, by a suitable convention, that a special sort of moral disapproval is the feeling which is being expressed.”

“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.”

“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.”

“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.”

“The criterion which we use to test the genuineness of apparent statements of fact is the criterion of verifiability. 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 — that is, if he knows what observations would lead him, under certain conditions, to accept the proposition as being true, or reject it as being false.”

“The traditional disputes of philosophers are, for the most part, as unwarranted as they are unfruitful. The surest way to end them is to establish beyond question what should be the purpose and method of a philosophical enquiry. And this is by no means so difficult a task as the history of philosophy would lead one to suppose. For if there are any questions which science leaves it to philosophy to answer, a straightforward process of elimination must lead to their discovery.”

“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.”

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