Logic Quotes

“At one time, many philosophers held that faultless "laws of thought" were somehow inherent, a priori, in the very nature of mind. This belief was twice shaken in the past century; first when Russell and his successors showed how the logic men employ can be defective, and later when Freud and Piaget started to reveal the tortuous ways in which our minds actually develop.”

“The statement of ideas in a poem may have to do with logic. More profoundly, it may be identified with the emotional progression of the poem, in terms of the music and images, so that the poem is alive throughout. Another, more fundamental statement in poetry, is made through the images themselves those declarations, evocative, exact, and musical, which move through time and are the actions of a poem.”

“Weak logic, inconsistencies and alienation from the people are common features of authoritarianism. The relentless attempts of totalitarian regimes to prevent free thought and new ideas and the persistent assertion of their own rightness bring on them an intellectual stasis which they project on to the nation at large. Intimidation and propaganda work in a duet of oppression, while the people, lapped in fear and distrust, learn to dissemble and to keep silent.”

“The trouble is that once America goes off to war, it can't very well return without having fought one. If it doesn't find its enemy, for the sake of the enraged folks back home, it will have to manufacture one. Once war begins, it will develop a momentum, a logic and a justification of its own, and we'll lose sight of why it's being fought in the first place.”

“The ontological concept of truth is in the centre of a logic which may serve as a model of pre- technological rationality. It is the rationality of a two-dimensional universe of discourse which, contrasts with the of thought and behavior that develop in the execution of the technological project.”

“In [Aristotle's] formal logic, thought is organized in a manner very different from that of the Platonic dialogue. In this formal logic, thought is indifferent toward its objects. Whether they are mental or physical, whether they pertain to society or to nature, they become subject to the same general laws of organization, calculation, and conclusion - but they do so as fungible signs or symbols, in abstraction from their particular "substance." This general quality (quantitative quality) is the precondition of law and order - in logic as well as in society - the price of universal control.”

“Dialectical logic undoes the abstractions of formal logic and of transcendental philosophy, but it also denies the concreteness of immediate experience. To the extent to which this experience comes to rest with the things as they appear and happen to be, it is a limited and even false experience. It attains its truth if it has freed itself from the deceptive objectivity which conceals the factors behind the facts - that is, if it understands its world as a historical universe, in which the established facts are the work of the historical practice of man.”

“Logic is not only an exact science, but is the most simple and elementary of all sciences; it ought therefore undoubtedly to find some place in every course of education.”

“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.”

“With all due respect, many in the entertainment industry are deep into mind-altering substance abuse, and when one's logic and intellectual calculating powers are replaced with dopey feel-good, fantasy-driven denial, the democratic party serves them well.”

“Like music or art, mathematical equations can have a natural progression and logic that can evoke rare passions in a scientist. Although the lay public considers mathematical equations to be rather opaque, to a scientist an equation is very much like a movement in a larger symphony. Simplicity. Elegance. These are the qualities that have inspired some of the greatest artists to create their masterpieces, and they are precisely the same qualities that motivate scientists to search for the laws of nature. LIke a work of art or a haunting poem, equations have a beauty and rhythm all their own.”

“Language is inherently not concerned with logic. As an expression of the psychological activities of humankind, it simply follows a linear process as it seeks actualisation. Moreover, it does not obey the objective concepts of time and space that belong to the physical world. When the discussion of time and space is imported into linguistic art from scientific aims and research methods, that linguistic art is entirely reduced to trifling pseudo-philosophical issues.”

“I am now about to set seriously to work upon preparing for the press an account of my theory of Logic and Probabilities which in its present state I look upon as the most valuable if not the only valuable contribution that I have made or am likely to make to Science and the thing by which I would desire if at all to be remembered hereafter.”

“We had stayed up all night, my friends and I, under hanging mosque lamps with domes of filigreed brass, domes starred like our spirits, shining like them with the prisoned radiance of electric hearts. For hours we had trampled our atavistic ennui into rich oriental rugs, arguing up to the last confines of logic and blackening many reams of paper with our frenzied scribbling.”

“What sets imperialism of the capitalist sort apart from other conceptions of empire is that it is the capitalist logic that typically dominates, though ... there are times in which the territorial logic comes to the fore. But this then poses a crucial question: how can the territorial logics of power, which tend to be awkwardly fixed in space, respond to the open spatial dynamics of endless capital accumulation? And what does endless capital accumulation imply for the territorial logics of power?”

“The main condition is that the spiritual ear should be open to overhear and patiently take in, and the will ready to obey that testimony which, I believe, God bears in every human heart, however dull, to those great truths which the Bible reveals. This, and not logic, is the way to grow in religious knowledge, to know that the truths of religion are not shadows, but deep realities.”

“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.”

“Dialectic, which is the parent of logic, came itself from rhetoric. Rhetoric is in turn the child of the myths and poetry of ancient Greece. That is so historically, and that is so by any application of common sense. The poetry and myths are the response of a prehistoric people to the Universe around them made on the basis of Quality. It is Quality, not dialectic, which is the generator of everything we know.”

“Knowledge is a continuous fabric, in which ideas are connected to other ideas. Reason-free zones, in which people can assert arbitrary beliefs safe from ordinary standards of evaluation, can only corrupt this fabric, just as a contradiction can corrupt a system of logic, allowing falsehoods to proliferate through it.”

“Unlike Hegel's progress model of history, which moves by stages, each containing its own logic of growth and decline, the economic model develops as the simple function of one money-variable over time, with a long-term trend which increases monotonically.”

“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.”
