There is nothing more deceptive than an obvious fact.

Whatever lies beyond the limits of experience, and claims another origin than that of induction and deduction from established data, is illegitimate.
Faith is the assent to any proposition not made out by the deduction of reason but upon the credit of the proposer.
When it happeneth that a man signifieth unto us two contradictory opinions whereof the one is clearly and directly signified, andthe other either drawn from that by consequence, or not known to be contradictory to it; then (when he is not present to explicate himself better) we are to take the former of his opinions; for that is clearly signified to be his, and directly, whereas the other might proceed from error in the deduction, or ignorance of the repugnancy.
If I had in me something that inspires people towards the good and raises them one step on the ladder of mental and spiritual progress, I want to show it by example, indication, and deduction, not by preaching, threatening, and conspiring.
Unless the structure of the nucleus has a surprise in store for us, the conclusion seems plain — there is nothing in the whole system of laws of physics that cannot be deduced unambiguously from epistemological considerations.
If, occasionally, historical evidence does not square with formulated laws, it should be remembered that a law is but a deduction from experience and experiment, and therefore laws must conform with historical facts, not facts with laws.
To give a causal explanation of an event means to deduce a statement which describes it, using as premises of the deduction one or more universal laws, together with certain singular statements, the initial conditions ... We have thus two different kinds of statement, both of which are necessary ingredients of a complete causal explanation.
There was something dead in my heart. I tried to figure out what it was by the strength of the smell. I knew that it was not a lion or a sheep or a dog. Using logical deduction, I came to the conclusion that it was a mouse. I had a dead mouse in my heart.
I presume that few who have paid any attention to the history of the Mathematical Analysis, will doubt that it has been developed in a certain order, or that that order has been, to a great extent, necessary -- being determined, either by steps of logical deduction, or by the successive introduction of new ideas and conceptions, when the time for their evolution had arrived.
I sometimes compare press officers to riflemen on the Somme -- mowing down wave upon wave of distortion, taking out rank upon rank of supposition, deduction and gossip.
It is a mistake to confound strangeness with mystery. The most commonplace crime is often the most mysterious because it presents no new or special features from which deductions may be drawn. This murder would have been infinitely more difficult to unravel had the body of the victim been simply found lying in the roadway without any of those outré and sensational accompaniments which have rendered it remarkable. These strange details, far from making the case more difficult, have really had the effect of making it less so.
Paradox is the sharpest scalpel in the satchel of science. Nothing concentrates the mind as effectively, regardless of whether it pits two competing theories against each other, or theory against observation, or a compelling mathematical deduction against ordinary common sense.
Jesse Jackson's in trouble. They're going after this tax thing. Jesse said he will amend his taxes to show the money that he paid to his mistress. See, he has just one mistress. Jesse uses the standard mistress deduction. As opposed to Clinton, who had to itemize.
It is a capital mistake to theorize before you have all the evidence. It biases the judgment.
In the study of ideas, it is necessary to remember that insistence on hard-headed clarity issues from sentimental feeling, as it were a mist, cloaking the perplexities of fact. Insistence on clarity at all costs is based on sheer superstition as to the mode in which human intelligence functions. Our reasonings grasp at straws for premises and float on gossamers for deductions.
I understand that the legal position is under review in South Africa and that there will soon be a broader set of organizations to which donors can give and claim tax deductions.
If Hillary [Clinton] is elected, is she going to be able to jack up taxes with virtually no deductions, and include capital gains? Unless democrats have a clean sweep of Congress, I don't think that's going to happen either.
We are approaching a new age of synthesis. Knowledge cannot be merely a degree or a skill... it demands a broader vision, capabilities in critical thinking and logical deduction without which we cannot have constructive progress.
If we believe that Jesus of Nazareth is the only begotten Son of God and that He came into this world and went to the cross of Calvary and died for our sins and rose again in order to justify us and to give us life anew and prepare us for heaven-if you really believe that, there is only one inevitable deduction, namely that He is entitled to the whole of our lives, without any limit whatsoever.
When I began my career as a cosmologist some twenty years ago, I was a convinced atheist. I never in my wildest dreams imagined that one day I would be writing a book purporting to show that the central claims of Judeo-Christian theology are in fact true, that these claims are straightforward deductions of the laws of physics as we now understand them. I have been forced into these conclusions by the inexorable logic of my own special branch of physics.
My own varying estimates of the facts themselves, as the years passed, showed me too clearly how much of history must always rest in the eye of the beholder; our deductions are so often different it is impossible they should always be right.
I'm not a detective from Baker Street or an old lady who solves crimes while she's knitting in an easy chair. I'm just a book girl. So I can't make a deduction, only take a flight of fancy--er, forget I said that. I meant, I can only take a guess.
My first encounters with faith came about the time I was a Boy Scout, at about 14 or 15. I made the logical deduction that they operate the same way; I treated my faith like earning a merit badge, and everything about Christianity was about earning merit badges.
But instinct is something which transcends knowledge. We have, undoubtedly, certain finer fibers that enable us to perceive truths when logical deduction, or any other willful effort of the brain, is futile.
It seems safe to look forward to the time when the conception of attractive and repulsive forces, having served its purpose as a useful piece of scientific scaffolding, will be replaced by the deduction of the phenomena known as attraction and repulsion, from the general laws of motion.
As Stephen Jay Gould pointed out in Time, in no other Western country is the teaching of Evolution regarded as controversial. Throughout the world, one way or another, most Christian denominations have managed to reconcile belief in God with belief in the mechanisms of natural selection. A French or German or Scandinavian politician who called for students to entertain as a reasonable deduction from existing evidence the proposition that Earth is at most 10,000 years old would be bundled off to a mental hospital.
You must therefore zealously guard in his mind the curious assumption 'My time is my own'. Let him have the feeling that he starts each day as the lawful possessor of twenty-four hours. Let him feel as a grievous tax that portion of this property which he has to make over to him employers, and as a generous donation that further portion which h allows to religious duties. But what he must never be permitted to doubt is that the total from which these deductions have been made was, in some mysterious sense, his own personal birthright.
In philosophy, when we make use of false principles, we depart the farther from the knowledge of truth and wisdom exactly in proportion to the care with which we cultivate them, and apply ourselves to the deduction of diverse consequences from them, thinking that we are philosophizing well, while we are only departing the farther from the truth; from which it must be inferred that they who have learned the least of all that has been hitherto distinguished by the name of philosophy are the most fitted for the apprehension of truth.
The true man of science will know nature better by his finer organization; he will smell, taste, see, hear, feel, better than other men. His will be a deeper and finer experience. We do not learn by inference and deduction and the application of mathematics to philosophy, but by direct intercourse and sympathy. It is with science as with ethics,--we cannot know truth by contrivance and method; the Baconian is as false as any other, and with all the helps of machinery and the arts, the most scientific will still be the healthiest and friendliest man, and possess a more perfect Indian wisdom.
We do not learn by inference and deduction and the application of mathematics to philosophy, but by direct intercourse and sympathy.
Why should ANYTHING go right; even observation and deduction? Why should not good logic be as misleading as bad logic? They are both movements in the brain of a bewildered ape?
Deduction, which takes us from the general proposition to facts again-teaches us, if I may so say, to anticipate from the ticket what is inside the bundle.
You can't remember sex. You can remember the fact of it, and recall the setting, and even the details, but the sex of the sex cannot be remembered, the substantive truth of it, it is by nature self-erasing, you can remember its anatomy and be left with a judgment as to the degree of your liking of it, but whatever it is as a splurge of being, as a loss, as a charge of the conviction of love stopping your heart like your execution, there is no memory of it in the brain, only the deduction that it happened and that time passed, leaving you with a silhouette that you want to fill in again.
It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.
A detective novel should contain no long descriptive passages, no literary dallying with side-issues, no subtly worked-out character analyses, no 'atmospheric' preoccupations. Such matters have no vital place in a record of crime and deduction. They hold up the action and introduce issues irrelevant to the main purpose, which is to state a problem, analyze it, and bring it to a successful conclusion. To be sure, there must be a sufficient descriptiveness and character delineation to give the novel verisimilitude.
There is synthesis when, in combining therein judgments that are made known to us from simpler relations, one deduces judgments from them relative to more complicated relations. There is analysis when from a complicated truth one deduces more simple truths.
Every American worker should be able to save for retirement via payroll deductions.
How do you think we have the home mortgage deduction? We have it because way back when it was determined that the American dream equaled home ownership. And everybody knows that the vast majority of the American people will never be able to write a check for a house. You have to finance it.
When we find that God's ways always coincide with our own ways, it's time to question who we're really worshipping, God or ourselves. The latter moves the nature of godliness from the King to our servant to a slave, a deduction into the realm of selfhood and then the lower, slavehood. It's a spiritual mathematics in that men who need God in his godhood are humble yet strong and spiritually ambitious while men who need a slave in their selfhood are ultimately paralyzed and will remain paralyzed.
A man who does not endeavour to seem more than he is will generally be thought nothing of. We habitually make such large deductions for pretence and imposture that no real merit will stand against them. It is necessary to set off our good qualities with a certain air of plausibility and self-importance, as some attention to fashion is necessary.
The grand aim of all science is to cover the greatest number of empirical facts by logical deduction from the smallest number of hypotheses or axioms.
I said that he was my superior in observation and deduction. If the art of the detective began and ended in reasoning from an armchair, my brother would be the greatest criminal agent that ever lived. But he has no ambition and no energy. He will not even go out of his way to verify his own solutions, and would rather be considered wrong than take the trouble to prove himself right.
Democracy is not a mathematical deduction proved once and for all time. Democracy is a just faith fervently held, commitment to be tested again and again in the fiery furnace of history.
The two operations of our understanding, intuition and deduction, on which alone we have said we must rely in the acquisition of knowledge.
This is an age of intellectual sauces, of essence, of distillation. We have conclusions without deductions, abridgments of history and abridgments of science without leading facts. We have animals for literature, Cabinet Encyclopaedias, Family Libraries, Diffusion Societies, and heaven knows what else! What is all this for? Not to add knowledge to the learned, but to tell points to the ignorant, without giving them the trouble to acquire the links. Oh! it is sad work. And the result will be injurious to all classes.
In every science, after having analysed the ideas, expressing the more complicated by means of the more simple, one finds a certain number that cannot be reduced among them, and that one can define no further. These are the primitive ideas of the science; it is necessary to acquire them through experience, or through induction; it is impossible to explain them by deduction.
A mind is accustomed to mathematical deduction, when confronted with the faulty foundations of astrology, resists a long, long time, like an obstinate mule, until compelled by beating and curses to put its foot into that dirty puddle.
And now, without having wearied my friends, I hope, with detailed scientific accounts, theories, or deductions, I will only say that I have endeavoured to tell just the story of the adventure itself.
I'd rather be an adviser. I don't wanna become a trainer because I think with the knowledge and the business sense that I've accomplished through my career and have credibility, why would I reduce myself down to being in a gym with a bunch of training which is not a bad thing to give advice, but I can do that with a suit and tie on and also be there when the cheques are written. I don't wanna be there when the cheques are handed down from 3 or 4 people's hands and then it hits mine as a trainer because 9/10 times, deductions have come out of that.
