Quotes About Logic

It is difficult to remove by logic an idea not placed there by logic in the first place. By nature, we are emotional creatures. Often we live and react based on feelings, not logic. Feelings are wonderful, but when we become tied to a particular thought or belief we tend to ignore the fact that change might be necessary.

To know and not to know, to be conscious of complete truthfulne­ss while telling carefully constructe­d lies, to hold simultaneo­usly two opinions which cancelled out, knowing them to be contradict­ory and believing in both of them, to use logic against logic, to repudiate morality while laying claim to it, to believe that democracy was impossible and that the Party was the guardian of democracy.

Logic plus logic equals the illogical. Do you know what I mean?

Anti-Semitism is best understood as a virus. It has no logic. Jews were hated because they were rich and because they were poor; because they were capitalists and because they were communists; because they held tenaciously to an ancient faith and because they were rootless cosmopolitans, believing nothing. Hate needs no logic. It is a sickness of the soul.

Poets do not go mad; but chess-players do. Mathematicians go mad, and cashiers; but creative artists very seldom. I am not, as will be seen, in any sense attacking logic: I only say that this danger does lie in logic, not in imagination.

But logic is not all, one needs one's heart to follow an idea.

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.

Every song has a composer, every book has an author, every car has a maker, every painting has a painter, and every building has a builder.

I am all for love, because love fails. You will be surprised - I have my own logic. I am all for love, because love fails.

And that is the danger: you become satisfied with a toy, you become satisfied with something plastic, artificial, man-made.

Mathematics does not grow through a monotonous increase of the number of indubitably established theorems but through the incessant improvement of guesses by speculation and criticism, by the logic of proofs and refutations.

Some people will follow their minds without listening to their hearts, and others will follow their hearts without listening to their minds. This is why reason exists, for there to be balance between the heart and mind. We were not meant to follow the mind and ignore the heart. Instead, we were meant to follow the heart over the mind, but without completely abandoning logic. The middle way is the preferred way, and this path simply means to allow your heart to drive you, but do not forget to balance reason with your conscience.

As in political revolutions, so in paradigm choice--there is no standard higher than the assent of the relevant community. To discover how scientific revolutions are effected, we shall therefore have to examine not only the impact of nature and of logic, but also the techniques of persuasive argumentation effective within the quite special groups that constitute the community of scientists.

This is not a new world - it is simply an extension of what began in the old one. It has patterned itself after every dictator who has ever planted the ripping imprint of a boot on the pages of history since the beginning of time. It has refinements...technological advances...and a more sophisticated approach to the destruction of human freedom. But like everyone of the super-states that preceded it - it has one iron rule: logic is an enemy and truth is a menace.

In life, particularly in public life, psychology is more powerful than logic.

We have an even worse situation in Syria, where the United States' allies are actually supporting people who are violently opposed to the United States, who are dangerous, radical Islamist fanatics. I mean, where is the logic of that? When are we going to call the Saudis on the support of intolerant, bigoted, fanatical types of Islam? When are we going to call this ally?

The decision-makers should communicate the customer pictures and the logic of the strategies and actions. That communication allows employees throughout the organization to implement the strategies and actions, tweaking them appropriately in response to variations in the marketplace. It also allows employees to recognize information in the marketplace that contradicts the customer pictures, either because the pictures were not entirely correct or because customers have changed.

When the logician has resolved each demonstration into a host of elementary operations, all of them correct, he will not yet be in possession of the whole reality, that indefinable something that constitutes the unity ...

The rejection of all abstract formalism. Materialism reminds every science of its real source: the world men transform. No science can, whether in its history or its object, grasp its own origins within itself or constitute itself as a closed world, exhaustively defined by internal rules. Materialism refers every science and every activity to the reality they depend on, even if this dependence is masked by a great many abstract mediations: mathematics as well as logic, aesthetics as well as ethics and politics.

My Father taught me how to be a man – and not by instilling in me a sense of machismo or an agenda of dominance. He taught me that a real man doesn’t take, he gives; he doesn’t use force, he uses logic; doesn’t play the role of trouble-maker, but rather, trouble-shooter; and most importantly, a real man is defined by what’s in his heart, not his pants.

Mathematics had never had more than a secondary interest for him ; and even logic he cared for chiefly as a means of clearing the ground of doctrines imagined to be proved, by showing that the evidence on which they were supposed to rest had no tendency to prove them. But he had been endeavouring to give a more active and positive help than this to the cause of what he deemed pure religion.
