Quotes & Sayings About Logical Reasoning

What a paradox it is, the sane causes more problems than the insane! It is! The real problems of the world do not come from the insane but, the sane! — Ernest Agyemang Yeboah

When the intensity of emotional conviction subsides, a man who is in the habit of reasoning will search for logical grounds in favour of the belief which he finds in himself. — Bertrand Russell

Passion has helped us; but can do so no more. It will in future be our enemy. Reason, cold, calculating, unimpassioned reason, must furnish all the materials for our future support and defence. — Abraham Lincoln

TEF is predicated on logic, a simple wager that every human faces:
If a reasoning human being loves and values life, they will want to live as long as possible-the desire to be immortal. Nevertheless, it's impossible to know if they're going to be immortal once they die. To do nothing doesn't help the odds of attaining immortality-since it seems evident that everyone will die someday and possibly cease to exist. To try to do something scientifically constructive towards ensuring immortality beforehand is the most logical conclusion. — Zoltan Istvan

The physicist, in his study of natural phenomena, has two methods of making progress: (1) the method of experiment and observation, and (2) the method of mathematical reasoning. The former is just the collection of selected data; the latter enables one to infer results about experiments that have not been performed. There is no logical reason why the second method should be possible at all, but one has found in practice that it does work and meets with reasonable success. — Paul Dirac

God cannot be understood by logical reasoning but only by submission. — Leo Tolstoy

Satan frequently steals the will of God from us due to reasoning. The Lord may direct us to do a certain thing, but if it does not make sense - if it is not logical - we may be tempted to disregard it. What God leads a person to do does not always make logical sense to his mind. His spirit may affirm it and His mind reject it, especially if it would be out of the ordinary or unpleasant or if it would require personal sacrifice or discomfort. — Joyce Meyer

Mathematics is not arithmetic. Though mathematics may have arisen from the practices of counting and measuring it really deals with logical reasoning in which theorems - general and specific statements - can be deduced from the starting assumptions. It is, perhaps, the purest and most rigorous of intellectual activities, and is often thought of as queen of the sciences. — Christopher Zeeman

Chess can help a child develop logical thinking, decision making, reasoning, and pattern recognition skills, which in turn can help math and verbal skills. — Susan Polgar

If scientific reasoning were limited to the logical processes of arithmetic, we should not get very far in our understanding of the physical world. One might as well attempt to grasp the game of poker entirely by the use of the mathematics of probability. — Vannevar Bush

The Church has realized that anything and everything can be built up on a document of that sort, no matter how contradictory or irreconcilable with it. The faithful will swallow it whole, so long as logical reasoning is never allowed to be brought to bear on it. — Adolf Hitler

In Architecture there is a part that is the result of Logical Reasoning and a part that is created through the Senses. There is always a point where they Clash. I don't think Architecture can be created without that Collision. — Tadao Ando

For my part, the more I went forward in the study of letters, and ever more easily, the greater became the ardour of my devotion to them, until in truth I was so enthralled by my passion for learning that, gladly leaving to my brothers the pomp of glory in arms, the right of heritage and all the honours that should have been mine as the eldest born, I fled utterly from the court of Mars that I might win learning in the bosom of Minerva. And
since I found the armory of logical reasoning more to my liking than the other forms of philosophy, I exchanged all other weapons for these, and to the prizes of victory in war I preferred the battle of minds in disputation. — Pierre Abelard

When I'm drawing - and here drawing is very different from writing or reasoning - I have the impression at certain moments of participating in something like a visceral function, such as digestion or sweating, a function that is independent of the conscious will. This impression is exaggerated, but the practice or pursuit of drawing touches, or is touched by, something prototypical and anterior to logical reasoning. — John Berger

Zen wants us to acquire an entirely new point of view whereby to look into the mysteries of life and the secrets of nature. This is because Zen has come to the definite conclusion that the ordinary logical process of reasoning is powerless to give final satisfaction to our deepest spiritual needs. — D.T. Suzuki

Geometry is beautifully logical, and it teaches you how to think and prove that things are so, step by step by step. Proofs are excellent lessons in reasoning. Without logic and reasoning, you are dependent on jumping to conclusions or - worse - having empty opinions. — Marilyn Vos Savant

Logical investigations can obviously be a useful tool for philosophy. They must, however, be informed by a sensitivity to the philosophical significance of the formalism and by a generous admixture of common sense, as well as a thorough understanding both of the basic concepts and of the technical details of the formal material used. It should not be supposed that the formalism can grind out philosophical results in a manner beyond the capacity of ordinary philosophical reasoning. There is no mathematical substitute for philosophy. — Saul Kripke

The sensible man,' Crow had said (to Sherlock Holmes), 'don't look to confirm what he already knows -- he looks to deny it. Finding evidence that backs up your theories ain't useful, but finding evidence that your theories are wrong is priceless. Never try to prove yourself right -- always try to prove yourself wrong instead. — Andy Lane

But men love abstract reasoning and neat systematization so much that they think nothing of distorting the truth, closing their eyes and ears to contrary evidence to preserve their logical constructions. — Fyodor Dostoyevsky

Logical reasoning may be a most convenient means of mental communication for covering short distances, but the curvature of the earth, alas, is reflected even in logic: an ideally rational progression of thought will finally bring you back to the point of departure where you return aware of the simplicity of genius, with a delightful sensation that you have embraced truth, while actually you have merely embraced your own self ... anything you might term a deduction already exposes the flaw: logical development inexorably becomes an envelopment. — Vladimir Nabokov

I have not come to know atheism as a result of logical reasoning and still less as an event in my life: in me it is a matter of instinct. — Friedrich Nietzsche

My eyes narrowed. I didn't like his logical reasoning. — Jennifer L. Armentrout

He kissed me again, farther up my neck, and I pushed him back against the wall.
My mind searched for the logical thought, a rational life raft before I drowned in wanting to hiss him. I managed, "We've only met a few days ago. We don't know each other."
Luke released me. "How long does it take to know someone?"
I didn't know. "A month? A few months?" It sounded stupid to quantify it, especially when I didn't want to believe my own reasoning. But I couldn't just go kissing someone I knew nothing about
it went against everything I'd ever been told. So why was it so hard to say no?
He took my fingers, playing with them in between his own. "I'll wait." He looked so good in the half-light under the trees, his light eyes nearly glowing against his shadowed skin. It was useless.
"I don't want you to." I whispered the words, and before I'd even finished saying them, his mouth was on mine and I was melting under his lips. — Maggie Stiefvater

Logical reasoning is an argument which we have with ourselves and which reproduces internally the features of a real argument. — Jean Piaget

What if it tempt you toward the flood, my lord?
Or to the dreadful summit of the cliff
That beetles o'er his base into the sea,
And there assume some other horrible form
Which might deprive your sovereignty of reason
And draw you into madness? Think of it.
[The very place puts toys of desperation,
Without more motive, into every brain
That looks so many fathoms to the sea
And hears it roar beneath.] — William Shakespeare

Play stimulates the parts of the brain involved in both careful, logical reasoning and carefree, unbound exploration. — Greg McKeown

Anything, anything at all can be logical. For something to be logical, it just has to be a valid example of reasoning from some set of premises. — Mark C. Chu-Carroll

According to this new evidence, most of our thinking (including our moral judgment) is not a pristinely rational process in the traditional sense, and therefore reasoning is not a bloodless, emotionless, purely formal logical process. Instead, we need an intact and functioning emotional apparatus in order for our reason to have any possibility of operating appropriately in a given situation. — Mark Johnson

He had a better mind and a more rigorous temperament than me; he thought logically, and then acted on the conclusion of logical thought. Whereas most of us, I suspect, do the opposite: we make an instinctive decision, then build up an infrastructure of reasoning to justify it. And call the result common sense. — Julian Barnes

Emotion is not a defect in an otherwise perfect reasoning machine. Reason, unfettered from human feeling, has led to as many horrors as any crusader's zeal. What use is pity in a world devoted to maximizing efficiency and productivity? Scientific husbandry tells us to weed out the sick, the infirm, the weak. The ruthless efficiency of euthanasia initiatives and ethnic cleansing are but the programmatic application of Nietzsche's point: from any quantifiable cost-benefit analysis, the principles of animal husbandry should apply to the human race. Charles Darwin himself acknowledged that strict obedience to "hard reason" rather than sympathy for fellow humans would represent a sacrifice of "the noblest part of our nature."6 It is the human heart resonating with empathy, not the logical brain attuned to the mathematics of efficiency, that revolts at cruelty and inhumanity. In — Terryl L. Givens

Criticism, I said, is an attempt to find the weak spots in a theory, and these, as a rule, can be found only in the more remote logical consequences which can be derived from it. It is here that purely logical reasoning plays an important part in science. — Karl Popper

A detective with his murder mystery, a chemist seeking the structure of a new compound, use little of the formal and logical modes of reasoning. Through a series of intuitions, surmises, fancies, they stumble upon the right explanation, and have a knack of seizing it when it once comes within reach. — Gilbert N. Lewis

In book two of his Rhetoric,2 Aristotle identified and explained three means of persuasion that a speaker may use: logos, pathos, and ethos. Logos is the logical argumentation and patterns of reasoning used to effect persuasion. Pathos includes the emotional involvement of both the speaker and the audience as they achieve persuasion. Ethos refers to the character of the speaker — R. Larry Overstreet

He thought logically, and then acted on the conclusion of logical thought. Whereas most of us, I suspect, do the opposite: we make an instinctive decision, then build up an infrastructure of reasoning to justify it. — Julian Barnes

George's son had done his work so thoroughly that he was considered too good a workman to live, and was, in fact, taken and tragically shot at twelve o'clock that same day - another instance of the untoward fate which so often attends dogs and other philosophers who follow out a train of reasoning to its logical conclusion, and attempt perfectly consistent conduct in a world made up so largely of compromise. — Thomas Hardy

You have to get off that finite road that you've created from your transitional standpoint and onto the path of light. Onto the infinite road of eternal existence, the firm foundation of truth. This is where the crooked becomes straight, the lost get found, the blind see, and the dead live. Where the tangible reasoning of logical man loses credibility and is proven unrealistic. Where faith becomes active and the world of the supernatural becomes obvious. You have to accept Jesus. Accept it, accept Jesus. — Calvin W. Allison

More by example than by word, my father taught me logical reasoning, compassion, love of others, honesty, and discipline applied with understanding. — Paul D. Boyer

My mind, my logical, practical, reasoning mind, is peeing in his mind pants. — Orson Scott Card

People falling in love for one reason may fall out of love due to another reason. However, if faith or trust is the basis of love, it does not break easily. Often people use all their reasoning to understand each other and even live together for years to satisfy themselves that they are in love. However, marriages based on such logical love, the love based on reason, do not last long. Quite to the contrary, marriages where the partners do not even know each other, survive for life - being based on mutual trust and faith. — Awdhesh Singh

What convinces is conviction. Believe in the argument you're advancing. If you don't you're as good as dead. The other person will sense that something isn't there, and no chain of reasoning, no matter how logical or elegant or brilliant, will win your case for you. — Lyndon B. Johnson

On the Logical Reasoning, ask the speaker: Oh yeah, asshole? What evidence do you have for that position? — Nathan Fox

Circular reasoning is infallible even if not exactly logical, and
this is why so many of us so often resort to it - not so much to
resolve baffling problems, but to be absolved of the obligation
to worry about them. — Zygmunt Bauman

If one's cause is supported by sound reasoning, there is no point in using violence. It is those who have no motive other than selfish desire and who cannot achieve their goal through logical reasoning who rely on force. — Dalai Lama
