Countless works in the social sciences reveal the inability of their
authors to bear in mind the crucial difference between
what may properly be called the **logic** of discovery
and the **logic** of demonstration. The second
isproperlysubjectto rules and prescriptions; the first isn't.

— 1976 Sociology as an Art Form, introduction.

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

— Chapter Three, The Business Of politics, p. 67

No one who was not by nature a lover of **logic**, and an extreme precisian in the use of words and phrases, could have written the two "Alice" books.

—

The very reason we need **logic** at all is because most reasoning is not conscious at all.

— Book I, Chapter 1, p. 41

Discovery in mathematics is not a matter of **logic**. It is rather the result of mysterious powers which no one understands, and in which unconscious recognition of beauty must play an important part. Out of an infinity of designs, a mathematician chooses one pattern for beauty's sake and pulls it down to earth.

It has been a long road from Plato's Meno to the present, but it is perhaps encouraging that most of the progress along that road has been made since the turn of the twentieth century, and a large fraction of it since the midpoint of the century. Thought was still wholly intangible and ineffable until modern formal **logic** interpreted it as the manipulation of formal tokens. And it seemed still to inhabit mainly the heaven of Platonic ideals, or the equally obscure spaces of the human mind, until computers taught us how symbols could be processed by machines.

— p.125 Computer Science as Empirical Inquiry: Symbols and Search (1975)

Capitalism inevitably and by virtue of the very **logic** of its civilization creates, educates and subsidizes a vested interest in social unrest.

— Part II, Chapter XIII, Section II, pg. 146

It had been different during his first year of graduate school, when he temporarily forsook physics to explore instead the realm of the senses. Applying **logic** to the late-blooming quandries of maturity, he had parsed the:;elements of encounter, banter, negotiation, and consummation, separating and solving the variables one by one until the problem if not generally solved did appear to have tractable special solutions.

— Part V (p. 236)

The plain fact is that many of the reputations which today occupy the poetic limelight are such as would crumble immediately if poetry such as Empson's, with its passion, **logic**, and formal beauty, were to become widely known.

— John Wain "Ambiguous Gifts", in

The line must follow some direction of policy, whether rooted in **logic** or experience. Lines should not be drawn simply for the sake of drawing lines.

— Dissenting in

A page of history is worth a volume of **logic**.

—

The world of visual perspective is one of unified and homogeneous space. Such a world is alien to the resonating diversity of spoken words. So language was the last art to accept the visual **logic** of Gutenberg technology, and the first to rebound in the electric age.

— p. 136 ("The Agenbite of Outwit")

… we’re not all the same. A common liberal refrain … is that differences between individuals are statistically more significant than those between cultural, ethnic, and racial groups. I don’t see why the fact of inter-individual differences would nullify inter-group variance. That’s liberal **logic** for you.

— “The Kindness of (Caucasian) Strangers”,

A logical theory may be tested by its capacity for dealing with puzzles, and it is a wholesome plan, in thinking about **logic**, to stock the mind with as many puzzles as possible, since these serve much the same purpose as is served by experiments in physical science.

— "On Denoting",

The conception of the necessary unit of all that is resolves itself into the poverty of the imagination, and a freer **logic** emancipates us from the straitwaistcoated benevolent institution which idealism palms off as the totality of being.

— p. 9. (Our Knowledge of the External World (1914))

The instincts of man are so earth-bound that they shrewdly sense it whenever the approach of **logic** threatens them.

— Chapter Five, Christian sources, p. 87

The want of **logic** annoys. Too much **logic** bores. Life eludes **logic**, and everything that **logic** alone constructs remains artificial and forced.

— André Gide (1956)

**logic** is **logic**. That's all I say.

— Oliver Wendell Holmes (1919),

Dialectical **logic** is loyal to the contradictions, not by the reasoning of “on the one hand and the other” but by tracing the contradictions to their fractured source.

— Russell Jacoby,

I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of **logic**, and every proposition of arithmetic a law of **logic**, albeit a derivative one. To apply arithmetic in the physical sciences is to bring **logic** to bear on observed facts; calculation becomes deduction.

— Gottlob Frege (1884)

**logic** doesn't apply to the real world. Mishima

— 1981 In Douglas R Hofstadter and Daniel C Dennett (eds) The Mind's I: fantasies and reflections on self and soul.

The fact that all Mathematics is Symbolic **logic** is one of the greatest discoveries of our age; and when this fact has been established, the remainder of the principles of mathematics consists in the analysis of Symbolic **logic** itself.

As the little boy said when asked if he wanted to be a lawyer like his mother, "Oh no, that's women's work." **logic** has nothing to do with oppression.

—

A certain maxim of **logic** which I have called Pragmatism has recommended itself to me for diverse reasons and on sundry considerations.

— Charles Sanders Peirce (1903)

**logic** is in the eye of the logician.
