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.
A poem generated by its own laws may be unrealized and bad in terms of so-called objective principles of taste, judgement, deduction.
Any photograph has multiple meanings: indeed, to see something in the form of a photograph is to encounter a potential object of fascination. The ultimate wisdom of the photographic image is to say: “There is the surface. Now think – or rather feel, intuit – what is beyond it, what the reality must be like if it looks this way.’ Photographs, which cannot themselves explain anything, are inexhaustible invitations to deduction, speculation, and fantasy
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 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.
"I should have more faith," he said; "I ought to know by this time that when a fact appears opposed to a long train of deductions it invariably proves to be capable of bearing some other interpretation."
All science is full of statements where you put your best face on your ignorance, where you say: ... we know awfully little about this, but more or less irrespective of the stuff we don't know about, we can make certain useful deductions.
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.
The knowledge of Natural-History, being Observation of Matters of Fact, is more certain than most others, and in my slender Opinion, less subject to Mistakes than Reasonings, Hypotheses, and Deductions are; ... These are things we are sure of, so far as our Senses are not fallible; and which, in probability, have been ever since the Creation, and will remain to the End of the World, in the same Condition we now find them.
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.
The highest-income Americans don't need tax-free health insurance, mortgage interest deductions or deferred taxation on retirement funds.
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.
The supreme task of the physicist is to arrive at those universal elementary laws from which the cosmos can be built up by pure deduction. There is no logical path to these laws; only intuition, resting on sympathetic understanding of experience, can reach them.
A trembling in the bones may carry a more convincing testimony than the dry documented deductions of the brain.
...We then examine a particular coding system in DNA and discover that UI [universal information] is conveyed within the genes. Using this DNA evidence and scientific laws governing UI as premises, we are able to develop sound, logical deductions. This leads us to the following conclusion: the God of the Bible exists and He is responsible for originating and embedding Universal Information into biological life.
For chemistry is no science form'd à priori; 'tis no production of the human mind, framed by reasoning and deduction: it took its rise from a number of experiments casually made, without any expectation of what follow'd; and was only reduced into an art or system, by collecting and comparing the effects of such unpremeditated experiments, and observing the uniform tendency thereof. So far, then, as a number of experimenters agree to establish any undoubted truth; so far they may be consider'd as constituting the theory of chemistry.
As long as you're a tax deduction, you'll always be safe in my house.
Here is the tragedy of theology in its distilled essence: The employment of high-powered human intellect, of genius, of profoundly rigorous logical deduction—studying nothing. In the Middle Ages, the great minds capable of transforming the world did not study the world; and so, for most of a millennium, as human beings screamed in agony—decaying from starvation, eaten by leprosy and plague, dying in droves in their twenties—the men of the mind, who could have provided their earthly salvation, abandoned them for otherworldly fantasies.
I think the media plays into the hands of false induction, genuine seduction taking place, wrong deductions, and the inevitable reductions. That's the way and the path of the visual.
It is difficult to distinguish deduction from what in other circumstances is called problem-solving. And concept learning, inference, and reasoning by analogy are all instances of inductive reasoning. (Detectives typically induce, rather than deduce.) None of these things can be done separately from each other, or from anything else. They are pseudo-categories.
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.
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.
I must begin with a good body of facts and not from a principle (in which I always suspect some fallacy) and then as much deduction as you please.
In the one instance, the dreamerloses sight of this object in a wilderness of deductions and suggestionsuntilhe finds the incitamentum, or first cause of his musings,... forgotten. In my case, the primary object was invariably frivolous, although assuming, through the medium of my distempered vision, a refracted and unreal importance.
Thinking is seeing.... Every human science is based on deduction, which is a slow process of seeing by which we work up from the effect to the cause; or, in a wider sense, all poetry like every work of art proceeds from a swift vision of things.
