quotations about logic
Logic is justly considered the basis of all other sciences, even if only for the reason that in every argument we employ concepts taken from the field of logic, and that ever correct inference proceeds in accordance with its laws.
ALFRED TARSKI
Introduction to Logic and to the Methodology of the Deductive Sciences
As to the most prudent logicians might venture to deduce from a skein of wool the probable existence of a sheep; so you, from the raw stuff of perception, may venture to deduce a universe which transcends the reproductive powers of your loom.
EVELYN UNDERHILL
Practical Mysticism
The mighty power of logic cleanses all it touches.

There can be no question of masking the evidence, of suppressing the absurd by denying one of the terms of its equation. It is essential to know whether one can live with it or whether, on the other hand, logic commands one to die of it.
ALBERT CAMUS
The Myth of Sisyphus and Other Essays
I know a logic beyond time and space; that is why I am so illogical, why space cannot hold me nor time make me old.
ELSA BARKER
Songs of a Vagrom Angel
When dealing with people, remember you are not dealing with creatures of logic, but with creatures bristling with prejudice and motivated by pride and vanity.
DALE CARNEGIE
How to Win Friends and Influence People
I am convinced that the act of thinking logically cannot possibly be natural to the human mind. If it were, then mathematics would be everybody's easiest course at school and our species would not have taken several millennia to figure out the scientific method.
NEIL DEGRASSE TYSON
The Sky is Not the Limit: Adventures of an Urban Astrophysicist
Fear is the enemy of logic.
FRANK SINATRA
attributed, The Way You Wear Your Hat
For the end of logic is to teach a form of argument to secure reason, and not to entrap it.
FRANCIS BACON
The Advancement of Learning
Logic is a crutch for the cripple, but a burden for the swift of foot and a greater burden still for the wise.
MIKHAIL NAIMY
The Book of Mirdad
Belief was immune to logic; it operated by its own laws.
JAMES SIEGEL
Detour
Logic takes care of itself; all we have to do is to look and see how it does it.
LUDWIG WITTGENSTEIN
Notebooks, Oct. 13, 1914
From a drop of water a logician could infer the possibility of an Atlantic or a Niagara without having seen or heard of one or the other.
SIR ARTHUR CONAN DOYLE
A Study in Scarlet
I am like a machine being driven to excessive rotations: the bearings are incandescing and, in a minute, melted metal will begin to drip and everything will turn to nothing. Quick: get cold water, logic. I am pouring it over myself by the bucketload but the logic sizzles on the hot bearings and dissipates elusive white steam into the air.

You can prove anything you want by coldly logical reason---if you pick the proper postulates.
ISAAC ASIMOV
I, Robot
There is no such thing as magic, supernatural, miracle; only something that's still beyond logic of the observer.
TOBA BETA
Betelgeuse Incident
You can only find truth with logic if you have already found truth without it.
G. K. CHESTERTON
attributed, G. K. Chesterton: Philosopher Without Portfolio
What is a logical mind?... It is the antiseptic which destroys the bacilli of unreason whereby true happiness is vivified.
WILLIAM JOHN LOCKE
The Morals of Marcus Ordeyne
Formal logic is fundamentally concerned with the form and structure of arguments and not, primarily, with their content.
PAUL TOMASSI
Logic
As we have already seen, logic has traditionally been described as the science of thought. If it is a science, however, logic is a theoretical science, not an empirical science.
