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

Michael Moorcock

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

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'.

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

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'

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.

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

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 many, many fields. I expected people in the social sciences-economics, psychology, philosophy, linguistics, politics, sociology, religion and numerous other areas to pick up on it. It's been somewhat of a mystery to me why even to this day, so few social scientists have discovered how useful it could be. Instead, Fuzzy Logic was first embraced by engineers and used in industrial process controls and in "smart" consumer products such as hand-held camcorders that cancel out jittering and microwaves that cook your food perfectly at the touch of a single button. I didn't expect it to play out this way back in 1965.

The problem is that it has become politically awkward to draw attention to absolutes of bad and good. In place of manners, we now have doctrines of political correctness, against which one offends at one's peril: by means of a considerable circular logic, such offences mark you as reactionary and therefore a bad person. Therefore if you say people are bad, you are bad.

Symbolism and meaning are two separate things. I think she found the right words by bypassing procedures like meaning and logic. She captured words in a dream, like delicately catching hold of a butterfly's wings as it flutters around. Artists are those who can evade the verbose.

Haruki Murakami

When faith is supported by facts or by logic it ceases to be faith.

Without deductive logic science would be entirely useless. It is merely a barren game to ascend from the particular to the general, unless afterwards we can reverse the process and descend from the general to the particular, ascending and descending like angels on Jacob's ladder.

Alfred North Whitehead

When we must pay the true price for the depletion of nature's gifts, materials will become more precious to us, and economic logic will reinforce, and not contradict, our heart's desire to treat the world with reverence and, when we receive nature's gifts, to use them well.

Charles Eisenstein

In many ways it is true to say that syntax is mathematical logic, semantics is philosophy or philosophy of science, and pragmatics is psychology, but these fields are not really all distinct.

Frank Honywill George

I am not a big fan of meaning. Logic is also another nebulous thought. I attempt to bring threads of subjects, however shaggy, to my work and inject little suggesters to the picture itself, and this often puts a smile on my face.

What a writer does is to try to make sense of life. I think that's what writing is, I think that's what painting is. It's seeking that thread of order and logic in the disorder, and the incredible waste and marvelous profligate character of life. What all artists are trying to do is to make sense of life.

Nadine Gordimer

Whatever is known to us by consciousness, is known beyond possibility of question. What one sees or feels, whether bodily or mentally, one cannot but be sure that one sees or feels. No science is required for the purpose of establishing such truths; no rules of art can render our knowledge of them more certain than it is in itself. There is no logic for this portion of our knowledge.

John Stuart Mill

When you cannot answer your opponent's logic, do not be discouraged—You can still call him vile names.

It's Adrian Ivashkov logic. Don't try to understand it. Just roll with it.

The enthronement of Christ over the minds of men is steadily going forward. His kingdom embraces the princes in the realm of mind. It embraces the nations of highest civilization. They are all beneath the cross. It is maintained by simple authority. Other mental monarchs rule by logic; Christ's word is law — it is satisfying to His subjects. His truth in the handsof His disciples, like the bread He broke upon the mountains, is an ample supply for the millions that gather at His table.

As is so often the case with a legend, every incident has two possible interpretations, the plausible and the one that is molded to suit the making of the myth. Man is a romantic at heart and will always put aside dull, plodding reason for the excitement of an enigma. As Doc had pointed out, mystery, not logic, is what gives us hope and keeps us believing in a force greater than our own insignificance.

Bryce Courtenay

Among the formal graphical methods are Frege's (1879) Begriffsschrift, Peirce's (1909) existential graphs, and Sowa's (1984) conceptual graphs. These three are based in first-order predicate logic.

Imagine an eye unruled by man-made laws of perspective, an eye unprejudiced by compositional logic, an eye which does not respond to the name of everything but which must know each object encountered in life through an adventure of perception. How many colors are there in a field of grass to the crawling baby unaware of 'Green?' How many rainbows can light create for the untutored eye?

Faith isn't about logic, son," Haddek said. "Perhaps that's your problem. You cannot 'disprove' the things you study, any more than we can prove to you that the Hero will save us. We simply must believe it, and accept the things Preservation has taught us.
