Logic Quotes

“It is well known that the central problem of the whole of modern mathematics is the study of transcendental functions defined by differential equations.”

“Logic should no longer be considered an elegant and learned accomplishment; it should take its place as an indispensable study for every well-informed person.”

“What seems certain is that Pythagoras developed the idea of mathematical logic. He realized that numbers exist independently of the tangible world and therefore their study was untainted by inaccuracies of perception. This meant he could discover truths which were independent of opinion of prejudice and which were more absolute than any previous knowledge.”

“Consensual paranoia - the pathology of the normal person who is a member of a war-justifying society - forms the template from which all the images of the enemy are created. By studying the logic of paranoia, we can see why certain archetypes of the enemy must necessarily recur, no matter what the historical circumstances.”

“From semantics to shipbuilding, from dream theory to propositional logic, any specialist ... is invariably astonished to discover that modern knowledge was foreshadowed at the time. ... Should we not replace these foreshadowings by the study of the influences of Hellenistic thought on modern thought?”

“Well, I kind of split my life into two pieces. One was where my chess career lies. There, I kept my sanity, so to speak, and my logic. And the other was my religious life. I tried to apply what I learned in the church to my chess career too. But I still was studying chess. I wasn't just "trusting in God" to give me the moves.”

“When I was at Notre Dame studying under Joe Evans, Frank O'Malley, and others, there was a very lively debate about the distinction between natural law and revealed truth. Most of the philosophers of church and state expected that what was going to be advocated as the law of the land would be related to natural law. If you attempted to draw lines about certain general moral truths that were derivative of logic and reason, they would prove to be widely shared, and therefore suitable to be enacted into law on both the civic and religious sides.”

“What a silly thing love is!' said the student as he walked away. 'It is not half as useful as logic, for it does not prove anything, and it is always telling one of things that are not going to happen, and making one believe things that are not true. In fact, it is quite unpractical, and, as in this age to be practical is everything, I shall go back to philosophy and study metaphysics.' So he returned to his room and pulled out a great dusty book, and began to read.”

“I used to think things were the way they are for a reason, that there was some hidden meaning. I used to think that this meaning governed the way the world was. But it's an illusion to think that there are good and bad reasons. Grammar is a lie to make us think that what we say is connected by a logic that you'll find if you study it, a lie that gone on for centuries. Because I now know that life just lurches between stability and instability and doesn't obey any law.”

“Like Molière's M. Jourdain, who spoke prose all his life without knowing it, mathematicians have been reasoning for at least two millennia without being aware of all the principles underlying what they were doing. The real nature of the tools of their craft has become evident only within recent times A renaissance of logical studies in modern times begins with the publication in 1847 of George Boole's The Mathematical Analysis of Logic.”

“In chess the most unbelievable thing for me is that it's a game for everybody: rich, poor, girl, boy, old, young. It's a fantastic game which can unite people and generations! It's a language which you'll find people "speak" in every country. If you reach a certain level you find a very rich world! Art, sport, logic, psychology, a battlefield, imagination, creativity not only in practical games but don't forget either how amazing a feeling it is to compose a study, for example (unfortunately that's not appreciated these days but it's a fantastic part of chess!).”

“Among all the liberal arts, the first is logic, and specifically that part of logic which gives initial instruction about words. ... [T]he word "logic" has a broad meaning, and is not restricted exclusively to the science of argumentative reasoning. [It includes] Grammar [which] is "the science of speaking and writing correctly-the starting point of all liberal studies."”

“If pressed to supplement Tweedledee's ostensive definition of logic with a discursive definition of the same subject, I would say that logic is the systematic study of the logical truths. Pressed further, I would say that a sentence is logically true if all sentences with its grammatical structure are true. Pressed further still, I would say to read this book.”

“[One way] researchers sometimes evaluate people's judgments is to compare those judgments with those of more mature or experienced individuals. This method has its limitations too, because mature or experienced individuals are sometimes so set in their ways that they can't properly evaluate new or unique conditions or adopt new approaches to solving problems.”
