Logic Quotes

As the dew drop slides down the leaf to wet the soil, they call it fall in love. Yet, do we know the way up from the way down?

~ R. N. Prasher

A : I know what you're going to say, B.B : Yes, I've dreamed about this chat, A.

~ Toba Beta

I had already established, as you know, that it was logically impossible for Kenneth to be distressed by anything that might occur between Ned and myself; but Kenneth, being an artist, has perhaps not studied logic and is unaware of the impossibility.

~ Sarah Caudwell

Fear and logic belong together.

~ Dee Williams

God cautions us in Isaiah 55:9 that his ways are not ours and his thoughts are higher than our thoughts (undoubtedly one of the grander understatements).God is warning us that he is not logical and that believing him to be logical will lead to all kinds of disappointment.Logic has been defined as 'the science or history of the human mind, as it traces the progress of our knowledge from our first conceptions through their different combinations, and the numerous deductions that result from comparing them with one another.'Doesn't sound much like God. Yet, we so often strain our relatively minuscule brains to conceive, combine, compare, and deduce. Then we fault God when his conclusions disagree.The repetition of this useless exercise leads to a form of insanity which ultimately manifests in denial of the existence of such an illogical God.

~ Ron Brackin

A great deal of thought is only a substitute for the thoughts that the individual would really find useful at the time.

~ Idries Shah

The world is full of people who will help you manufacture tornados in order to blow out a match.

~ Shaun Hick

Comparison is the most abused intellectual tool of all. We compare men and women, man and God, good and bad, equal and unequal, forgetting that this sin only results in a punishment so severe that we can't even trace it back to its origins. All we're left with in the end is ambiguity, uncertainty, lethargy and and Kafka!

~ Raheel Farooq

Chélan had acted as imprudently for Julien as he had for himself. He had given him the habit of reasoning correctly, and of not being put off by empty words, but he had neglected to tell him that this habit was a crime in the person of no importance, since every piece of logical reasoning is offensive.

~ Stendhal

Eventually we will all wither and die in the wasteland of logic and science.

~ Julie Kagawa

Logic is the last scientific ingredient of Philosophy; its extraction leaves behind only a confusion of non-scientific, pseudo problems.

~ Rudolf Carnap

Like Molière’s M. Jourdain, who spoke prose all his life without knowing it, mathematicians have been reasoning for at least two millennia without being aware of all the principles underlying what they were doing. The real nature of the tools of their craft has become evident only within recent times A renaissance of logical studies in modern times begins with the publication in 1847 of George Boole’s 'The Mathematical Analysis of Logic'.

~ Ernest Nagel

At the time I thought the winner in an argument was the person who put forward the most logical support for his position. Of course, this isn't true. Human history, from gardening disputes to genocide, is full of examples of people with the most decent, well-argued stance ending up with their face in the mud in front of a naked display of power.

~ Mark Barrowcliffe

Five GOP representative candidates this session have shocked me to my soul at how blatant they have trivialized rape. My prayers were answered in their defeat!

~ Diane Chamberlain

I think a strong claim can be made that the process of scientific discovery may be regarded as a form of art. This is best seen in the theoretical aspects of Physical Science. The mathematical theorist builds up on certain assumptions and according to well understood logical rules, step by step, a stately edifice, while his imaginative power brings out clearly the hidden relations between its parts. A well constructed theory is in some respects undoubtedly an artistic production. A fine example is the famous Kinetic Theory of Maxwell. ... The theory of relativity by Einstein, quite apart from any question of its validity, cannot but be regarded as a magnificent work of art.

~ Ernest Rutherford

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

And intuition is what people is what people use in life to make decisions.But logic can help you work out the right answer.

~ Mark Haddon

Life is only logical, and to think it's a gift is depressing.

~ Konrad

The pessimist reason that things just happen, where the optimist believe that things happen for a reason.

~ Anthony Liccione

This may seem labouring the obvious, but in Japan one meets intelligent people who claim that ‘logic’ is something invented in the West to allow Westerners to win discussions. Indeed, the belief is widespread that the Japanese can as happily do without logic now as they supposedly have for centuries past.

~ Karel Van Wolferen

Mathematics had never had more than a secondary interest for him [her husband, George Boole]; and even logic he cared for chiefly as a means of clearing the ground of doctrines imagined to be proved, by showing that the evidence on which they were supposed to give rest had no tendency to prove them.

~ Mary Everest Boole

Logic is a mere iceberg in the Mediterranean of wisdom.

~ Raheel Farooq

You don't love someone because it's the logical thing to do.

~ Marty Rubin

Life corrects the errors of logic.

~ Marty Rubin

Life teaches us that human thought almost never walks hand in hand with logic, and it is usually counterproductive to raise the point.

~ Jeff Lindsay

1. God is (by definition) a being than which no greater being can be thought.2. Greatness includes greatness of virtue.3. Therefore, God is a being than which no being could be more virtuous.4. But virtue involves overcoming pains and dangers.5. Indeed, a being can only be properly said to be virtuous if it can suffer pain or be destroyed.6. A God that can suffer pain or is destructible is not one than which no greater being can be thought.7.For you can think of a greater being, that is, one that is nonsuffering and indestructible.8. Therefore, God does not exist.

~ Douglas N. Walton

If a mathematician wishes to disparage the work of one of his colleagues, say, A, the most effective method he finds for doing this is to ask where the results can be applied. The hard pressed man, with his back against the wall, finally unearths the researches of another mathematician B as the locus of the application of his own results. If next B is plagued with a similar question, he will refer to another mathematician C. After a few steps of this kind we find ourselves referred back to the researches of A, and in this way the chain closes.

~ Alfred Tarski

Objectivity begins with the realization that one is subjective.

~ Donovan M. Neal

There were no footmarks.''Meaning that you saw none?''I assure you, sir, that there were none.''My good Hopkins, I have investigated many crimes, but I have never yet seen one which was committed by a flying creature. As long as the criminal remains upon two legs so long must there be some indentation, some abrasion, some trifling displacement which can be detected by the scientific searcher.

~ Arthur Conan Doyle

I, therefore, for one, cannot see my way to accepting the agnostic rules for truth-seeking, or wilfully agree to keep my willing nature out of the game. I cannot do so for this plain reason, that a rule of thinking which would absolutely prevent me from acknowledging certain kinds of truth if those kinds of truth were really there, would be an irrational rule.

~ William James

Rationality doesn’t exist, right is absence of wrongness and wrong is what seems to be unfair.

~ M.f. Moonzajer

Logic, it is often said, is the study of valid arguments. It is a systematic attempt to distinguish valid arguments from invalid arguments.

~ W.h. Newton-Smith

We are most often inspired and motivated by fallacy rather than logic.

~ M.f. Moonzajer

Paradoxes are less paradoxical in their reference to truth than most of the most plausible axioms.

~ Raheel Farooq

Religion and philosophy have different logics, speak different languages. Their logics are mutually exclusive, languages sometimes overlapping. It is hard to find something really common in them. I think I---a man in totally unconditional pursuit of happiness, whatever it is, wherever it lies---am only supposed to consider which of them has more in common with life!

~ Raheel Farooq

Intellect is limited, but it has one great merit; it can recognise its limits!

~ Raheel Farooq

There is room for words on subjects other than last words.

~ Robert Nozick

The greatest of fools are those who fail to mark the invisible from the nonexistent.

~ Raheel Farooq

Intelligence is to spot paradoxes. Wisdom is to live by them.

~ Raheel Farooq

Ever since Plato most philosophers have considered it part of their business to produce ‘proofs’ of immortality and the existence of God. They have found fault with the proofs of their predecessors — Saint Thomas rejected Saint Anselm's proofs, and Kant rejected Descartes' — but they have supplied new ones of their own. In order to make their proofs seem valid, they have had to falsify logic, to make mathematics mystical, and to pretend that deepseated prejudices were heaven-sent intuitions.

~ Bertrand Russell
