A Quote by Herbert Marcuse

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.

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.

Gordon Livingston

The way people really think is not adequately analyzed by the universal categories of logic. Between social history and formal analyses of thought there is a path, a lane - maybe very narrow - which is the path of the historian of thought.

Michel Foucault

In other words, the propositions of philosophy are not factual, but linguistic in character - that is, they do not describe the behaviour of physical, or even mental, objects; they express definitions, or the formal consequences of definitions. Accordingly we may say that philosophy is a department of logic. For we will see that the characteristic mark of a purely logical enquiry, is that it is concerned with the formal consequences of our definitions and not with questions of empirical fact.

A.J. Ayer

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.

Allen Newell

Man is a thinking being. The way he thinks is related to society, politics, economics, and history and is also related to very general and universal categories and formal structures. But thought is something other than societal relations.

Michel Foucault

Formal logic is mathematics, and there are philosophers like Wittgenstein that are very mathematical, but what they're really doing is mathematics - it's not talking about things that have affected computer science; it's mathematical logic.

Lawrence M. Krauss

Logic is the science of the laws of thought, as thought,--that is of the necessary conditions to which thought considered in itself is a subject.

Sir William Hamilton, 9th Baronet

I end with a word on the new symbols which I have employed. Most writers on logic strongly object to all symbols. ... I should advise the reader not to make up his mind on this point until he has well weighed two facts which nobody disputes, both separately and in connexion. First, logic is the only science which has made no progress since the revival of letters; secondly, logic is the only science which has produced no growth of symbols.

Augustus De Morgan

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

Andre Gide

Logic is invincible, because in order to combat logic it is necessary to use logic.

Pierre Boutroux

Logic and truth are two very different things, but they often look the same to the mind that's performing the logic.

Theodore Sturgeon

I hope you become comfortable with the use of logic without being deceived into concluding that logic will inevitably lead you to the correct conclusion.

Neil Armstrong

[Aristotle formal logic thus far (1787)] has not been able to advance a single step, and hence is to all appearances closed and completed.

Immanuel Kant

By abstaining from all definite content, whether as formal logic and theory of science or as the legend of Being beyond all beings, philosophy declared its bankruptcy regarding concrete social goals.

Theodor Adorno

For me, all fiction is about prizing the logic of metaphors - which is the logic of narratives in general - over reality, which is irreducibly random and senseless.

Ken Liu

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
