Logic Quotes - page 5

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. (Bertrand Russell)
The rules of logic are to mathematics what those of structure are to architecture.
Bertrand Russell
Crime is common. Logic is rare. Therefore it is upon the logic rather than upon the crime you should dwell.
Arthur Conan Doyle
The logic now in use serves rather to fix and give stability to the errors which have their foundation in commonly received notions than to help the search for truth. So it does more harm than good.
Francis Bacon
Since my logic aims to teach and instruct the understanding, not that it may with the slender tendrils of the mind snatch at and lay hold of abstract notions (as the common logic does), but that it may in very truth dissect nature, and discover the virtues and actions of bodies, with their laws as determined in matter; so that this science flows not merely from the nature of the mind, but also from the nature of things.
Francis Bacon

Fear is the enemy of logic. There is no more debilitating, crushing, self-defeating, sickening thing in the world--to an individual or to a nation.
Frank Sinatra
Well, I kind of split my life into two pieces. One was where my chess career lies. There, I kept my sanity, so to speak, and my logic. And the other was my religious life. I tried to apply what I learned in the church to my chess career too. But I still was studying chess. I wasn't just "trusting in God" to give me the moves.
Bobby Fischer
Most of the mistakes in thinking are inadequacies of perception rather than mistakes of logic. (Edward de Bono)

I probably hold the distinction of being one movie star who, by all laws of logic, should never have made it. At each stage of my career, I lacked the experience.
Audrey Hepburn
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
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 then any previous knowledge.
Simon Singh
Logic only gives man what he needs... Magic gives him what he wants.

Insolence is not logic; epithets are the arguments of malice. (Robert G. Ingersoll)
I think that women are wonderful but I've never met one yet who didn't show more feeling than logic.
Hermann Göring
Forgotten were the elementary rules of logic, that extraordinary claims require extraordinary evidence and that what can be asserted without evidence can also be dismissed without evidence.
Christopher Hitchens
Since reasoning, or inference, the principal subject of logic, is an operation which usually takes place by means of words, and in complicated cases can take place in no other way: those who have not a thorough insight into both the signification and purpose of words, will be under chances, amounting almost to certainty, of reasoning or inferring incorrectly.
John Stuart Mill
Logic is neither an art nor a science but a dodge.
Stendhal
