Logic Quotes

“In my own view, some advice about what should be known, about what technical education should be acquired, about the intense motivation needed to succeed, and about the carelessness and inclination toward bias that must be avoided is far more useful than all the rules and warnings of theoretical logic.”

“Ordinarily logic is divided into the examination of ideas, judgments, arguments, and methods. The two latter are generally reduced to judgments, that is, arguments are reduced to apodictic judgments that such and such conclusions follow from such and such premises, and method is reduced to judgments that prescribe the procedure that should be followed in the search for truth.”

“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.”

“Humans suffer from self-centred notions as to the nature of life. Humans assume that alien life forms should conform to standards that match our own, including logic and morality. Even among humans, morality is ignored when expedient. Why should we expect more from an alien life form than we demand from ourselves?”

“These algorithms, which I'll call public relevance algorithms, are-by the very same mathematical procedures-producing and certifying knowledge. The algorithmic assessment of information, then, represents a particular knowledge logic, one built on specific presumptions about what knowledge is and how one should identify its most relevant components. That we are now turning to algorithms to identify what we need to know is as momentous as having relied on credentialed experts, the scientific method, common sense, or the word of God.”

“The whole world knows that American TV companies have monopolized Olympic broadcasts and in order to please the fans in their country they do everything they can to keep American viewers interested in what is going on at the hockey rink in Sochi. According to their logic, Americans should always win, no matter what. It was absolutely obvious that [Fyodor] Tyutin's goal yesterday should have been allowed. This was clear to the whole world except the American referee, American TV and those officials with American passports who rule international hockey, grossly neglecting all Olympic principles.”

“No living creature, not even man, has achieved, in the centre of his sphere, what the bee has achieved in her own: and were some one from another world to descend and ask of the earth the most perfect creation of the logic of life, we should needs have to offer the humble comb of honey.”

“The miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve. We should be grateful for it and hope that it will remain valid in future research and that it will extend, for better or for worse, to our pleasure, even though perhaps also to our bafflement, to wide branches of learning.”

“It is impossible to discuss realism in logic without drawing in the empirical sciences... A truly realistic mathematics should be conceived, in line with physics, as a branch of the theoretical construction of the one real world and should adopt the same sober and cautious attitude toward hypothetic extensions of its foundation as is exhibited by physics.”

“I end with a word on the new symbols which I have employed. Most writers on logic strongly object to all symbols. ... I should advise the reader not to make up his mind on this point until he has well weighed two facts which nobody disputes, both separately and in connexion. First, logic is the only science which has made no progress since the revival of letters; secondly, logic is the only science which has produced no growth of symbols.”

“The art of reasoning becomes of first importance. In this line antiquity has left us the finest models for imitation; I should consider the speeches of Livy, Sallust, and Tacitus, as pre-eminent specimens of logic, taste, and that sententious brevity which, using not a word to spare, leaves not a moment for inattention to the hearer. Amplification is the vice of modern oratory.”
