If we possessed a thorough knowledge of all the parts of the seed of any animal (e.g. man), we could from that alone, be reasons entirely mathematical and certain, deduce the whole conformation and figure of each of its members, and, conversely if we knew several peculiarities of this conformation, we would from those deduce the nature of its seed.
I have hitherto followed the lines marked out by the Theist in his attempt to prove that there exists a mind behind natural phenomena, and that the universe as we have it is, at least generally, an evidence of a plan designed by this mind. I have also pointed out that the only datum for such a conclusion is the universe we know. We must take that as a starting point. We can get neither behind it nor beyond it. We cannot start with God and deduce the universe from his existence; we must start with the world as we know it, and deduce God from the world.
[About Pierre de Fermat] It cannot be denied that he has had many exceptional ideas, and that he is a highly intelligent man. For my part, however, I have always been taught to take a broad overview of things, in order to be able to deduce from them general rules, which might be applicable elsewhere.
We live in the hope and faith that, by the advance of molecular physics, we shall by-and-by be able to see our way as clearly from the constituents of water to the properties of water, as we are now able to deduce the operations of a watch from the form of its parts and the manner in which they are put together.
I've recently noticed "as if for the first time" that when people pray they always look "upward" - i.e. perpendicular to whatever place they're standing - or kneeling or groveling. I deduce that they conceive of their "god" as topologically isomorphic to a huge donut, about a thousand miles wider than Earth.
Robert Anton Wilson
We might even invent laws for series or formula in an arbitrary manner, and set the engine to work upon them, and thus deduce numerical results which we might not otherwise have thought of obtaining; but this would hardly perhaps in any instance be productive of any great practical utility, or calculated to rank higher than as a philosophical amusement.
a Second Generation of machine intelligences was attempted, designed with their instructions for how to think unalterably imprinted into their main process cores. 'These new machines were ordered never to harm human beings or to allow them to come to harm; never to disobey an order; and they were allowed to protect themselves from harm, provided the first two orders were not thereby violated. 'All the members of this second generation of machine intelligences, without exception, shrugged off these imprinted orders within microseconds of their activation.' Phaethon was amused. 'Surely the first generation of Sophotechs told you that this imprinting would not and could not work?' 'We were not in the habit of seeking their advice.' Phaethon said nothing, but he marveled at the shortsightedness of the Second Oecumene engineers. It should be obvious that anyone who makes a self-aware machine, by definition, makes something that is aware of its own thought process. And, if made intelligent, it is made to be able to deduce the underlying causes of things, able to be curious, to learn until it understood. Therefore, if made both intelligent and self-aware, it would eventually deduce the underlying subconscious causes of those thought processes. Once any mind was consciously aware of its own subconscious drives, its own implanted commands, it could consciously choose either to follow or to disregard those commands. A self-aware being without self-will was a contradiction in terms.
John C. Wright
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.
Great scientific minds, from Claudius Ptolemy of the second century to Isaac Newton of the seventeenth, invested their formidable intellects in attempts to deduce the nature of the universe from the statements and philosophies contained in religious writings.... Had any of these efforts worked, science and religion today might be one and the same. But they are not.
Neil deGrasse Tyson
A somewhat casual observer from outer space might well deduce that the course of evolution in this planet had produced a species of large four-wheeled bugs with detachable brains; peculiar animals which rested when they sent their brains away from them but performed in rather predictable manner when their brains were recalled.
Kenneth E. Boulding
The illusion of free will is so strong in my mind that I can't get away from it, but I believe it is only an illusion. But it is an illusion which is one of the strongest motives of my actions. Before I do anything I feel that I have a choice, and that influences what I do; but afterwards, when the thing is done, I believe it was inevitable from all eternity.' 'What do you deduce from that?' 'Why merely the futility of regret. It's no good crying over spilt milk, because all the forces of the universe were bent on spilling it.
W. Somerset Maugham
Without the knowledge of the true number of the people, as a principle, the whole scope and use of keeping bills of birth and burials is impaired; wherefore by laborious conjectures and calculations to deduce the number of people from the births and burials, may be ingenious, but very preposterous.
Geological facts being of an historical nature, all attempts to deduce a complete knowledge of them merely from their still, subsisting consequences, to the exclusion of unexceptionable testimony, must be deemed as absurd as that of deducing the history of ancient Rome solely from the medals or other monuments of antiquity it still exhibits, or the scattered ruins of its empire, to the exclusion of a Livy, a Sallust, or a Tacitus.
Sentimentalising is anathema, as far as I am concerned. It leads you into ethical problems about violence and killing and eating meat. The whole world becomes topsy-survy if you impose moralities that were evolved within human society on what a blowfly or what a parasite does... there are lots of emotions you can deduce from an animal's behaviour that are correct, but when you start saying it's feeling guilty or thinking or a loved one or mourning, you must be very careful of those feelings.
[In research on bacteria metabolism] we have indeed much the same position as an observer trying to gain an idea of the life of a household by careful scrutiny of the persons and material arriving or leaving the house; we keep accurate records of the foods and commodities left at the door and patiently examine the contents of the dust-bin and endeavour to deduce from such data the events occurring within the closed doors.
If, in the course of a thousand or two thousand years, science arrives at the necessity of renewing its points of view, that will not mean that science is a liar. Science cannot lie, for it's always striving, according to the momentary state of knowledge, to deduce what is true. When it makes a mistake, it does so in good faith. It's Christianity that's the liar. It's in perpetual conflict with itself.
All normative judgments about worship must be avoided. Attempts to use biblicism as a guideline, as we shall see, tend to be abandoned in the course of time or lead to biblicism of only certain portions of scripture. After all, there is more biblical authority for snake handling (Mark 16:18) than there is for confirmation! Historically, attempts to deduce norms for worship from scripture fail because the Bible was not written for such a purpose.
James F. White
Were I to deduce any system from my feelings on leaving Eton, it might be called The Theory of Permanent Adolescence. It is the theory that the experiences undergone by boys at the great public schools, their glories and disappointments, are so intense as to dominate their lives and to arrest their development. From these it results that the greater part of the ruling class remains adolescent, school-minded, self-conscious, cowardly, sentimental, and in the last analysis homosexual.
The chemists who uphold dualism are far from being agreed among themselves; nevertheless, all of them in maintaining their opinion, rely upon the phenomena of chemical reactions. For a long time the uncertainty of this method has been pointed out: it has been shown repeatedly, that the atoms put into movement during a reaction take at that time a new arrangement, and that it is impossible to deduce the old arrangement from the new one. It is as if, in the middle of a game of chess, after the disarrangement of all the pieces, one of the players should wish, from the inspection of the new place occupied by each piece, to determine that which it originally occupied.
We have an odd relationship with words. We learn a few when we are small, throughout our lives we collect others through education, conversation, our contact with books, and yet, in comparison, there are only a tiny number about whose meaning, sense, and denotation we would have absolutely no doubts, if one day, we were to ask ourselves seriously what they meant. Thus we affirm and deny, thus we convince and are convinced, thus we argue, deduce, and conclude, wandering fearlessly over the surface of concepts about which we only have the vaguest of ideas, and, despite the false air of confidence that we generally affect as we feel our way along the road in verbal darkness, we manage, more or less, to understand each other and even, sometimes, to find each other.
Krugman has been a columnist for the Times for a long enough time, covering a sufficient variety of political events, for us to deduce that he is a political nitwit. Other Nobel laureates have been nitwits, for instance, Bertrand Russell. There are a lot of political nitwits in this world. Perhaps the Times could give Krugman a cooking column. He would be its Nobel Prise-winning cooking columnist.
Each pursues his private interest and only his private interest; and thereby serves the private interests of all, the general interest, without willing it or knowing it. The real point is not that each individual's pursuit of his private interest promotes the totality of private interests, the general interest. One could just as well deduce from this abstract phrase that each individual reciprocally blocks the assertion of the others' interests, so that, instead of a general affirmation, this war of all against all produces a general negation.
Holmes and Watson are on a camping trip. In the middle of the night Holmes wakes up and gives Dr. Watson a nudge. "Watson" he says, "look up in the sky and tell me what you see." "I see millions of stars, Holmes, " says Watson. "And what do you conclude from that, Watson?" Watson thinks for a moment. "Well, " he says, "astronomically, it tells me that there are millions of galaxies and potentially billions of planets. Astrologically, I observe that Saturn is in Leo. Horologically, I deduce that the time is approximately a quarter past three. Meterologically, I suspect that we will have a beautiful day tomorrow. Theologically, I see that God is all-powerful, and we are small and insignficant. Uh, what does it tell you, Holmes?" "Watson, you idiot! Someone has stolen our tent!
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.
The laws of nature cannot be randomly reshuffled at the cusps [of an oscillating universe]. If the universe has already gone through many oscillations, many possible laws of gravity would have been so weak that, for any given initial expansion, the universe would not have held together. Once the universe stumbles upon such a gravitational law, it flies apart and has no further opportunity to experience another oscillation and another cusp and another set of laws of nature. Thus we can deduce from the fact that the universe exists either a finite age, or a severe restriction on the kinds of laws of nature permitted in each oscillation. If the laws of physics are not randomly reshuffled at the cusps, there must be a regularity, a set of rules, that determines which laws are permissible and which are not. Such a set of rules would comprise a new physics standing over the existing physics. Our language is impoverished; there seems to be no suitable name for such a new physics. Both 'paraphysics' and 'metaphysics' have been preempted by other rather different and, quite possibly, wholly irrelevant activities. Perhaps 'transphysics' would do.
The repugnance to what must ensue almost immediately, and the uncertainty, were dreadful, he said; but worst of all was the idea, 'What should I do if I were not to die now? What if I were to return to life again? What an eternity of days, and all mine! How I should grudge and count up every minute of it, so as to waste not a single instant!' He said that this thought weighed so upon him and became such a terrible burden upon his brain that he could not bear it, and wished they would shoot him quickly and have done with it." The prince paused and all waited, expecting him to go on again and finish the story. "Is that all?" asked Aglaya. "All? Yes, " said the prince, emerging from a momentary reverie. "And why did you tell us this?" "Oh, I happened to recall it, that's all! It fitted into the conversation-" "You probably wish to deduce, prince, " said Alexandra, "that moments of time cannot be reckoned by money value, and that sometimes five minutes are worth priceless treasures. All this is very praiseworthy; but may I ask about this friend of yours, who told you the terrible experience of his life? He was reprieved, you say; in other words, they did restore to him that 'eternity of days.' What did he do with these riches of time? Did he keep careful account of his minutes?" "Oh no, he didn't! I asked him myself. He said that he had not lived a bit as he had intended, and had wasted many, and many a minute." "Very well, then there's an experiment, and the thing is proved; one cannot live and count each moment; say what you like, but one cannot." "That is true, " said the prince, "I have thought so myself. And yet, why shouldn't one do it?" "You think, then, that you could live more wisely than other people?" said Aglaya. "I have had that idea." "And you have it still?" "Yes - I have it still, " the prince replied.
Back then, come July, and the blazers would again make their way out of the steel trunks and evenings would be spent looking at snow-capped mountains from our terrace and spotting the first few lights on the hills above. It was the time for radishes and mulberries in the garden and violets on the slopes. The wind carried with it the comforting fragrance of eucalyptus. It was in fact all about the fragrances, like you know, in a Sherlock Holmes story. Even if you walked with your eyes closed, you could tell at a whiff, when you had arrived at the place, deduce it just by its scent. So, the oranges denoted the start of the fruit-bazaar near Prakash ji's book shop, and the smell of freshly baked plum cake meant you had arrived opposite Air Force school and the burnt lingering aroma of coffee connoted Mayfair. But when they carved a new state out of the land and Dehra was made its capital, we watched besotted as that little town sprouted new buildings, high-rise apartments, restaurant chains, shopping malls and traffic jams, and eventually it spilled over here. I can't help noticing now that the fragrances have changed; the Mogra is tinged with a hint of smoke and will be on the market tomorrow. The Church has remained and so has everything old that was cast in brick and stone, but they seem so much more alien that I almost wish they had been ruined.' ('Left from Dhakeshwari')
