When you try to translate any kind of real-life problem into a neat logical form, you're almost always simplifying it. We need a kind of blend - we need to use not just tools of logic, which are important and valuable - I'm not denying that, but also tools of judgement, and of inductive and abductive reasoning which can also inform.

When intuition and logic agree, you are always right.

When I was at Notre Dame studying under Joe Evans, Frank O'Malley, and others, there was a very lively debate about the distinction between natural law and revealed truth. Most of the philosophers of church and state expected that what was going to be advocated as the law of the land would be related to natural law.

After the advice he had given, Peyna would have been stunned to see Ben here. He had forgotten that the logic of all the wise old men in the world cannot often stand against the logic of a boy’s heart, if the boy’s heart is large and kind and loyal. Ben Staad’s was all three.

All deliberate change comes first from denying the logic that earlier gave you comfort.

All faults or defects, from the slightest misconduct to the most flagitious crime, Pantocyclus attributed to some deviation from perfect Regularity in the bodily figure, caused perhaps (if not congenital) by some collision in a crowd; by neglect to take exercise, or by taking too much of it; or even by a sudden change of temperature, resulting in a shrinkage or expansion in some too susceptible part of the frame. Therefore, concluded that illustrious Philosopher, neither good conduct nor bad conduct is a fit subject, in any sober estimation, for either praise or blame. For why should you praise, for example, the integrity of a Square who faithfully defends the interests of his client, when you ought in reality rather to admire the exact precision of his right angles? Or again, why blame a lying, thievish Isosceles when you ought rather to deplore the incurable inequality of his sides? Theoretically, this doctrine is unquestionable; but it has practical drawbacks. In dealing with an Isosceles, if a rascal pleads that he cannot help stealing because of his unevenness, you reply that for that very reason, because he cannot help being a nuisance to his neighbours, you, the Magistrate, cannot help sentencing him to be consumed - and there's an end of the matter. But in little domestic difficulties, where the penalty of consumption, or death, is out of the question, this theory of Configuration sometimes comes in awkwardly; and I must confess that occasionally when one of my own Hexagonal Grandsons pleads as an excuse for his disobedience that a sudden change of the temperature has been too much for his perimeter, and that I ought to lay the blame not on him but on his Configuration, which can only be strengthened by abundance of the choicest sweetmeats, I neither see my way logically to reject, nor practically to accept, his conclusions. For my own part, I find it best to assume that a good sound scolding or castigation has some latent and strengthening influence on my Grandson's Configuration; though I own that I have no grounds for thinking so. At all events I am not alone in my way of extricating myself from this dilemma; for I find that many of the highest Circles, sitting as Judges in law courts, use praise and blame towards Regular and Irregular Figures; and in their homes I know by experience that, when scolding their children, they speak about "right" or "wrong" as vehemently and passionately as if they believed that these names represented real existences, and that a human Figure is really capable of choosing between them.

All men are mortal. Socrates was mortal. Therefore, all men are Socrates.

A man goes to a foreign country and kills somebody who's not aggressing against him; in a Hawaiian shirt he's a criminal, in a green costume he's a hero who gets a parade and a pension. So that, as a culture, we remain in a state of moral insanity. To point out these contradictions to people in society is to be labeled insane. This is how insane society remains, that anybody who points out logical opposites in the most essential human topic of ethics, is considered to be insane.

A man of logic is a man of sin.

Analytic philosophy, that is to say, can very occasionally produce practically conclusive results of a negative kind. It can show in a few cases that just too much incoherence and inconsistency is involved in some position for any reasonable person to continue to hold it. But it can never establish the rational acceptability of any particular position in cases where each of the alternative rival positions available has sufficient range and scope and the adherents of each are willing to pay the price necessary to secure coherence and consistency. Hence the peculiar flavor of so much contemporary analytic writing—by writers less philosophically self-aware than Rorty or Lewis—in which passages of argument in which the most sophisticated logical and semantic techniques available are deployed in order to secure maximal rigor alternate with passages which seem to do no more than cobble together a set of loosely related arbitrary preferences; contemporary analytic philosophy exhibits a strange partnership between an idiom deeply indebted to Frege and Carnap and one deriving from the more simple-minded forms of existentialism

And' and 'or' are the basic operations of logic. Together with 'no' (the logical operation of negation) they are a complete set of basic logical operations—all other logical operations, no matter how complex, can be obtained by suitable combinations of these.

A distinguished writer [Siméon Denis Poisson] has thus stated the fundamental definitions of the science: 'The probability of an event is the reason we have to believe that it has taken place, or that it will take place.' 'The measure of the probability of an event is the ratio of the number of cases favourable to that event, to the total number of cases favourable or contrary, and all equally possible' (equally like to happen). From these definitions it follows that the word probability, in its mathematical acceptation, has reference to the state of our knowledge of the circumstances under which an event may happen or fail. With the degree of information which we possess concerning the circumstances of an event, the reason we have to think that it will occur, or, to use a single term, our expectation of it, will vary. Probability is expectation founded upon partial knowledge. A perfect acquaintance with all the circumstances affecting the occurrence of an event would change expectation into certainty, and leave neither room nor demand for a theory of probabilities.

A doctor, a logician and a marine biologist had also just arrived, flown in at phenomenal expense from Maximegalon to try to reason with the lead singer who had locked himself in the bathroom with a bottle of pills and was refusing to come out till it could be proved conclusively to him that he wasn't a fish. The bass player was busy machine-gunning his bedroom and the drummer was nowhere on board. Frantic inquiries led to the discovery that he was standing on a beach on Santraginus V over a hundred light years away where, he claimed, he had been happy for over half an hour now and had found a small stone that would be his friend.

All Medicines are poisons, and all poisons should be looked at for medicinal properties.

All people, whether Aspie or neuro-typical are predisposed by their society to make guesses, jump to conclusions and then seek to defend those conclusions, regardless of logic or changing circumstance.
