The big lie and monotonously repeated nonsense have more emotional appeal in a cold war than logic and reason.

A successful politician must not only be able to read the mood of the public, he must have the skill to get the public on his side. The public is moved by mood more than logic, by instinct more than reason, and that is something that every politician must make use of or guard against

Few persons care to study logic, because everybody conceives himself to be proficient enough in the art of reasoning already. But I observe that this satisfaction is limited to one's own ratiocination and does not extend to that of other men.
We come to the full possession of our power of drawing inferences the last of all our faculties, for it is not so much a natural gift as a long and difficult art.

Charles Sanders Peirce

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.

Maurice Maeterlinck

Well, I knew it was going to be important. That much I knew. In fact, I had thought about sealing it in a dated envelope with my predictions and then opening it 20-30 years later to see if my intuitions were right. I realized this paper marked a new direction. I used to think about it this way-that one day Fuzzy Logic would turn out to be one of the most important things to come out of our Electrical Engineering Computer Systems Division at Berkeley. I never dreamed it would become a worldwide phenomenon. My expectations were much more modest.

All opinions are not equal. Some are a very great deal more robust, sophisticated and well supported in logic and argument than others.

Throughout the nineteenth century, apart from the division in theoretical sciences and arts, classifiers attempted to divide the sciences into two groups. Already they had before them the examples of Francis Bacon (speculative and descriptive) and Hobbes (quantitative and qualitative). For Coleridge, the sciences were either pure (Grammar, Logic, Rhetoric, Mathematics, Metaphysics) or mixed. Arthur Schopenhauer's similar groups were called pure and empirical, Wilhelm Wundt in 1887 called them formal and empirical, Globot mathematical and theoretical, and the St. Louis Congress of Arts and Sciences (1904) normative and physical. Karl Pearson made similar division of the sciences into abstract and concrete

Brian Campbell Vickery

Logic, n. The art of thinking and reasoning in strict accordance with the limitations and incapacities of the human misunderstanding.

When you are faced with prejudice, logic and justice are impotent. Still, we may have an obligation to argue directly into the face of the prejudice, even though there is no chance to win.

The mind is led on, step by step, to defeat its own logic.

Doctor Who has never pretended to be hard science fiction … At best Doctor Who is a fairytale, with fairytale logic about this wonderful man in this big blue box who at the beginning of every story lands somewhere where there is a problem.

I am not a complete idiot, but whether from weakness or laziness have no talent for thinking. I know only how to reflect: I am a mirror... Logic does not exist for me. I float on the waves of art and life and never really know how to distinguish what belongs to the one or the other or what is common to both. Life unfolds for me like a theatre presenting a sequence of somewhat unreal sentiments; while the things of art are real to me and go straight to my heart.

Sviatoslav Richter

The choice is not between order and liberty. It is between liberty with order and anarchy without either. There is danger that, if the Court does not temper its doctrinaire logic with a little practical wisdom, it will convert the constitutional Bill of Rights into a suicide pact.

Robert H. Jackson

It'll probably be brutal, too. They might even feed you to the dog. He doesn't have a dog. Yeah, well, he might get one just to feed you to it. She'd never been the kind of person to let something as ridiculous as rational logic interfere with her fear.' (Alix)

Sherrilyn Kenyon

I think that women are wonderful but I've never met one yet who didn't show more feeling than logic.

Hermann Göring

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.

There can be no doubt that the knowledge of logic is of considerable practical importance for everyone who desires to think and infer correctly.

So do something that would have worked anyway whether God is real or not, and then simply assume that it worked because God is real. Of course. That's religious logic for you.

I have never managed to grasp what exactly 'pataphysics' consisted of; but in short what I have always seen in it is a desire to disconnect philosophy from the discipline of logic, and to admit incoherence as a legitimate component of it.

Remark on visiting frequently the Collège de 'Pataphysique'

Cole chuckled, saying, Fear of spiders is arachnophobia, and fear of tight spaces is claustrophobia, but fear of Ali Bell is just called logic.

Scenario: In the summer of 1977 The Human League was formed due to the members finding no conventional channels for their immense talents.
Background: None of The Human League have any orthodox musical training, but prefer to regard compositions as an extension of logic, inspiration and luck. Therefore, unlike conventional musicians, their influences are not so obvious.
Conclusion/Manifesto: Interested in combining the best of all worlds, The League would like to positively affect the future by close attention to the present, allying technology with humanity and humour. They have been described as 'Later Twentieth Century Boys' and 'Intelligent, Innovatory and Immodest'.

I have used the word 'flow' at many places without really elaborating its meaning. What is this flow? And what are these joys? I could call them moments of magic. I see an analogy between these moments and the high that you experience when you play badminton or go jogging. Flow is a sensation we experience when we act with total involvement. During flow, action follows action according to an internal logic that seems to need no conscious intervention on the part of the worker. There is no hurry, there are no distracting demands on one's attention. The past and the future disappear. So does the distinction between self and the activity.

A. P. J. Abdul Kalam

The Lords of Chaos are
the enemies of Logic,
the jugglers of Truth,
the molders of Beauty

Michael Moorcock

History of science played a very important role for me. Before I knew well how to do an experiment, I knew why Joliot has missed the neutron, why his wife missed the fission, why they succeeded in having artificial radioactivity, and even why they almost missed the other things, by doing very nice experiments, but didn't come to the conclusion. That is science. Science is doubt, is research. It is not something which is – and that is the danger of teaching – which is too academic and which the people explain you it is like the logic thing that comes out of the computer, which is not true. You have intuition, you have passion.

Georges Charpak

Business and its logic of productivity have become the reference point in a society that thinks marketing every time it opens its mouth.
