There are two basic ways to criticize an argument:
■ Challenge the premises-show that at least one is false.
■ Challenge the reasoning-show that the premises are not a good reason for the conclusion.

And one of the commonest forms of fallacious reasoning arising from ambiguity, is that of arguing from a metaphorical expression as if it were literal; that is, as if a word, when applied metaphorically, were the same name as when taken in its original sense: which will be seen more particularly in its place.

Through many types of abstraction and analogy-making and inductive reasoning, and through many long and tortuous chains of citations of all sorts of authorities (which constitute an indispensable pillar supporting every adult’s belief system, despite the insistence of high-school teachers who year after year teach that “arguments by authority” are spurious and are convinced that they ought to be believed because they are, after all, authority figures), we build up an intricate, interlocked set of beliefs as to what exists “out there” — and then, once again, that set of beliefs folds back, inevitably and seamlessly, to apply to our own selves.

Just this past summer, I took online courses in introductory logic and law through civilization. Often the weight of history, with its facts heaped upon facts requiring complex chains of inference to sort through – I mean complex for someone with the soft brain of a tomato merchant; for me the premises are obvious and the conclusions dire and inescapable – threatened to crush me, and I was ultimately forced to abandon the whole undertaking. By way of recovery, I spent the rest of the summer immersed in a Freudian meditation on some choice tabloids. The mysterious lives of celebrities make for challenging induction. The reasoning process involves navigating many gaps in our knowledge of them. What is certain is that under the iceberg of glitz and glamor lie neurotic, depraved individuals with bizarre habits and hobbies, people who think they’re above the law.

The word 'proof' should strictly only be used when we are dealing with deductive inferences.... Popper claimed that scientists only need to use deductive inferences.... So if a scientist is only interested in demonstrating that a given theory is false, she may be able to accomplish her goal without the use of inductive inferences.... When a scientist collects experimental data, her aim might be to show that a particular theory...is false. She will have to resort to inductive reasoning.... So Popper's attempt to show that science can get by without induction does not succeed.

No discussion of logic is complete without a refresher course in the difference between inductive and deductive reasoning. By its strictest definition, inductive reasoning proves a general principle—your idea worth spreading—by highlighting a group of specific events, trends, or observations. In contrast, deductive reasoning builds up to a specific principle—again, your idea worth spreading—through a chain of increasingly narrow statements.

In the progress of science from its easiest to its more difficult problems, each great step in advance has usually had either as its precursor, or as its accompaniment and necessary condition, a corresponding improvement in the notions and principles of logic received among the most advanced thinkers. And if several of the more difficult sciences are still in so defective a state; if not only so little is proved, but disputation has not terminated even about the little which seemed to be so; the reason perhaps is, that men's logical notions have not yet acquired the degree of extension, or of accuracy, requisite for the estimation of the evidence proper to those particular departments of knowledge.

The soul which fathoms every league of the celestial arc--knows, as a mariner the sea, the distant latitudes where comets flame, and worlds career, and constellations shake their awful clusters--wanders amid the spectral nebula, and makes suns and systems to be but glittering beads upon the aspiring thread of its induction, cannot perish. There is a future life. In a universe so spherical and whole as this, reason argues that its own incompleteness and capacity for more are suggestive--are prophetical.

The whole power, beauty, and (for want of a better word) piety of the sciences lie in that fruitful narrowness of focus that I mentioned above, that austere abdication of metaphysical pretensions that permits them their potentially interminable inductive and theoretical odyssey through the physical order. It is the purity of this vocation to the particular that is the special glory of science. This means that the sciences are, by their very nature, commendably fragmentary and, in regard to many real and important questions about existence, utterly inconsequential. Not only can they not provide knowledge of everything; they cannot provide complete knowledge of anything. They can yield only knowledge of certain aspects of things as seen from one very powerful but inflexibly constricted perspective. If they attempt to go beyond their methodological commissions, they cease to be sciences and immediately become fatuous occultisms. The glory of human reason, however, is its power to exceed any particular frame of reference or any single perspective, to employ an incalculable range of intellectual faculties, and to remain open to the whole horizon of being’s potentially infinite intelligibility. A wise and reflective person will not forget this. A microscope may conduct the eye into the mysteries of a single cell, but it will not alert one to a collapsing roof overhead; happily we have more senses than one. We may even possess spiritual senses, however much we are discouraged from trusting in them at present. A scientist, as a reasoning person, has as much call as anyone else to ponder the deepest questions of existence, but should also recognize the threshold at which science itself falls silent—for the simple reason that its silence at that point is the only assurance of its intellectual and moral integrity.

But in connection with mathematics the one-sidedness of the Greek genius appears: it reasoned deductively from what appeared self-evident, not inductively from what had been observed. Its amazing successes in the employment of this method misled not only the ancient world, but the greater part of the modern world also. It has only been very slowly that scientific method, which seeks to reach principles inductively from observations of particular facts, has replaced the Hellenic belief in deduction from luminous axioms derived from the mind of the philosopher. For this reason, apart from others, it is a mistake to treat the Greeks with superstitious reverence. Scientific method, though some few among them were the first men who had an inkling of it, is, on the whole, alien to their temper of mind, and the attempt to glorify them by belittling the intellectual progress of the last four centuries has a cramping effect upon modern thought.

It is for this reason that St. Dionysius and other mystic theologians call infused contemplation a ray of darkness,4 that is, for the unenlightened and unpurified soul, because this great supernatural light masters the natural power of the reason and takes away its natural way of understanding. Therefore, David also says: “Cloud and darkness are round about Him”;5 not that this is so in reality, but in reference to our weak understanding, which, in light so great, becomes dimmed and blind, unable to ascend so high. He repeats it, saying: “At the brightness that was before Him the clouds passed,”6 that is, between Him and our understanding. This is the reason why the illuminating ray of hidden wisdom, when God sends it from Himself into the soul not yet transformed, produces thick darkness in the understanding. 5. This dim contemplation is in its beginnings painful also to the soul. For as the infused divine contemplation contains many excellences in the highest degree, and the soul, which is the recipient, because not yet pure, is involved in many miseries—in the highest degree, too7—the result is—as two contraries cannot co-exist in the same subject—that the soul must suffer and be in pain, being the subject in which the two contraries meet, and resist each other because of the purgation of the soul from its imperfections, which is being wrought by contemplation.

But the Hermetic Teachings go much further than do those of modern science. They teach that all manifestation of thought, emotion, reason, will or desire, or any mental state or condition, are accompanied by vibrations, a portion of which are thrown off and which tend to affect the minds of other persons by "induction." This is the principle which produces the phenomena of "telepathy"; mental influence, and other forms of the action and power of mind over mind, with which the general public is rapidly becoming acquainted, owing to the wide dissemination of occult knowledge by the various schools, cults and teachers along these lines at this time.
Every thought, emotion or mental state has its corresponding rate and mode of vibration. And by an effort of the will of the person, or of other persons, these mental states may be reproduced, just as a musical tone may be reproduced by causing an instrument to vibrate at a certain rate — just as color may be reproduced in the same way. By a knowledge of the Principle of Vibration, as applied to Mental Phenomena, one may polarize his mind at any degree he wishes, thus gaining a perfect control over his mental states, moods, etc. In the same way he may affect the minds of others, producing the desired mental states in them. In short, he may be able to produce on the Mental Plane that which science produces on the Physical Plane — namely, "Vibrations at Will." This power of course may be acquired only by the proper instruction, exercises, practice, etc., the science being that of Mental Transmutation, one of the branches of the Hermetic Art.

1. Divine Writing: The Bible, down to the details of its words, consists of and is identical with God’s very own words written inerrantly in human language. 2. Total Representation: The Bible represents the totality of God’s communication to and will for humanity, both in containing all that God has to say to humans and in being the exclusive mode of God’s true communication.[11] 3. Complete Coverage: The divine will about all of the issues relevant to Christian belief and life are contained in the Bible.[12] 4. Democratic Perspicuity: Any reasonably intelligent person can read the Bible in his or her own language and correctly understand the plain meaning of the text.[13] 5. Commonsense Hermeneutics: The best way to understand biblical texts is by reading them in their explicit, plain, most obvious, literal sense, as the author intended them at face value, which may or may not involve taking into account their literary, cultural, and historical contexts. 6. Solo Scriptura:[14] The significance of any given biblical text can be understood without reliance on creeds, confessions, historical church traditions, or other forms of larger theological hermeneutical frameworks, such that theological formulations can be built up directly out of the Bible from scratch. 7. Internal Harmony: All related passages of the Bible on any given subject fit together almost like puzzle pieces into single, unified, internally consistent bodies of instruction about right and wrong beliefs and behaviors. 8. Universal Applicability: What the biblical authors taught God’s people at any point in history remains universally valid for all Christians at every other time, unless explicitly revoked by subsequent scriptural teaching. 9. Inductive Method: All matters of Christian belief and practice can be learned by sitting down with the Bible and piecing together through careful study the clear “biblical” truths that it teaches. The prior nine assumptions and beliefs generate a tenth viewpoint that—although often not stated in explications of biblicist principles and beliefs by its advocates—also commonly characterizes the general biblicist outlook, particularly as it is received and practiced in popular circles: 10. Handbook Model: The Bible teaches doctrine and morals with every affirmation that it makes, so that together those affirmations comprise something like a handbook or textbook for Christian belief and living, a compendium of divine and therefore inerrant teachings on a full array of subjects—including science, economics, health, politics, and romance.[15]

Blyton is not demanding. She is not an expander of minds like any one of the imaginatively and linguistically gifted authors already mentioned or still to be discussed. Her great gift lies in proving beyond doubt to children that reading can be fun, and reliably so. That the marks on the page will translate into life and colour and movement with ease. This is a thing you can master, a foundation upon which you can build, and also a retreat into which you can escape. She makes it all possible, time and time again. It was for this reason that Roald Dahl – whose own professed primary aim in writing for children was always to entertain them and thus induct them into the world of books – went to bat for her when he was on the 1988 Committee on English in the National Curriculum. He fell out with the rest of the board on the issue of whether her books should be welcomed in schools. Despite being no fan of either the work or the woman (he played bridge with her once and said afterwards that she had the mind of a child) he thought they should be embraced because they got children reading. The rest of the board disagreed and Dahl resigned his place.

Although inductions have been attempted for thousands of years, in the past, they were usually done because the baby was already dead or because the mother was sick. Now they tend to be done for less pressing reasons, which may include the obstetrician’s dinner reservations.* In theory, they’re done only when they’re best for mother or baby, but the timing of them makes it pretty clear staffing concerns are a factor as well.

This is why one hears scientists talking about the “theory” of evolution. It is not an observed fact; rather, it is a conclusion that is supported by all the facts observed so far, but one can never be absolutely sure because one can never see the whole universe at once, and because of the provisional nature of inductive reasoning, scientists hold out the possibility, no matter how small, that it could be invalidated. Science thus demands intellectual honesty, and a scientific conclusion will always contain a provisional statement: All observed swans are white; therefore, all swans are probably white.

Beginning students of physics quickly become acquainted with idealizations like the notion of a frictionless surface, and with the fact that laws like Newton’s law of gravitation strictly speaking describe the behavior of bodies only in the circumstance where no interfering forces are acting on them, a circumstance which never actually holds. Moreover, physicists do not in fact embrace a reg ularity as a law of nature only after many trials, after the fashion of popular presentations of inductive reasoning. Rather, they draw their conclusions from a few highly specialized experiments conducted under artificial conditions. This is exactly what we should expect if what science is concerned with is discovering the hidden natures of things. Actual experimental practice indicates that what physicists are really looking for are the powers a thing will manifest when interfer ing conditions are removed, and the fact that a few experiments, or even a single controlled experiment, are taken to establish the results in question indicates that these powers are taken to reflect a nature that is universal to things of that type.

To cooperate effectively one needs a good theory of mind (to intuit what another person is thinking), the ability to communicate through language, the faculty to reason, and an ability to suppress one’s urges. Hunting and gathering also requires good memory to remember where and when to find different foods, as well as a naturalist’s mind to predict where foods will be.

It is pretty clear, then, that attention can control the brain’s sensory processing. But it can do something else, too, something that we only hinted at in our discussion of neuroplasticity. It is a commonplace observation that our perceptions and actions do not take place in a vacuum. Rather, they occur on a stage set that has been concocted from the furniture of our minds. If your mind has been primed with the theory of pointillism (the use of tiny dots of primary colors to generate secondary colors), then you will see a Seurat painting in a very different way than if you are ignorant of his technique. Yet the photons of light reflecting off the Seurat and impinging on your retina, there to be conveyed as electrical impulses into your visual cortex, are identical to the photons striking the retina of a less knowledgeable viewer, as well as of one whose mind is distracted. The three viewers “see” very different paintings. Information reaches the brain from the outside world, yes—but in “an ever-changing context of internal representations,” as Mike Merzenich put it. Mental states matter. Every stimulus from the world outside impinges on a consciousness that is predisposed to accept it, or to ignore it. We can therefore go further: not only do mental states matter to the physical activity of the brain, but they can contribute to the final perception even more powerfully than the stimulus itself. Neuroscientists are (sometimes reluctantly) admitting mental states into their models for a simple reason: the induction of cortical plasticity discussed in the previous chapters is no more the simple and direct product of particular cortical stimuli than the perception of the Seurat painting is unequivocally determined by the objective pattern of photons emitted from its oil colors: quite the contrary.

Empiricism is a related concept; it assumes that the ultimate and true source of knowledge is experience, or inductive reasoning from experience. In other words, if something cannot be experienced through the senses, it should not be accepted as truth.
In the Islamic conceptualization, it is clear that the reality is much more complex than modern scientists will admit. The unseen world (phenomena or aspects that cannot be known using ordinary human faculties) is actually much more extensive than the seen world, and this unseen world interacts with and influences the world that we observe.

Wikipedia: Pygmalion effect
The Pygmalion effect, or Rosenthal effect, is a psychological phenomenon in which high expectations lead to improved performance in a given area. …
… According to the Pygmalion effect, the targets of the expectations internalize their positive labels, and those with positive labels succeed accordingly; a similar process works in the opposite direction in the case of low expectations. The idea behind the Pygmalion effect is that increasing the leader's expectation of the follower's performance will result in better follower performance.
… The educational psychologist Robert L. Thorndike described the poor quality of the Pygmalion study. The problem with the study was that the instrument used to assess the children's IQ scores was seriously flawed. The average reasoning IQ score for the children in one regular class was in the mentally disabled range, a highly unlikely outcome in a regular class in a garden variety school. In the end, Thorndike concluded that the Pygmalion findings were worthless. It is more likely that the rise in IQ scores from the mentally disabled range was the result of regression toward the mean, not teacher expectations. Moreover, a meta-analysis conducted by Raudenbush showed that when teachers had gotten to know their students for two weeks, the effect of a prior expectancy induction was reduced to virtually zero.

Sheep and Goats One way of independently checking the results suggested by the hypnosis studies is to examine another form of suggestion, one that is in some ways stronger than conventional hypnotic induction. These are the subtle suggestions induced in us by our culture, our personal experiences, and the beliefs we learned from parents and schools. Together, culture, experience, and beliefs are potent shapers of our sense of reality. They are, in effect, hidden persuaders, powerful reinforcers of our sense of what is real. Our deep beliefs determine what we view as logically reasonable and what we consider to be morally and ethically self-evident. As we’ll explore in more detail in chapter 14, the hidden “hypnosis” of belief actually determines to a greater degree than is commonly known what we can consciously perceive. The hypnosis experiments showed that a slight tweaking of these beliefs resulted in a different performance. Thus, we would expect that people who accept the existence of ESP—for reasons of culture, experience, or belief—will score higher, on average, than people who do not. This turns out to be one of the most consistent experimental effects in psi research. It was whimsically dubbed the “sheep-goat” effect by psychologist Gertrude Schmeidler, who in 1943 proposed that one reason that confirmed skeptics do not report psi experiences is because they subconsciously avoid them.37 People who do report such experiences Schmeidler called the “sheep,” and the skeptics she called the “goats.” These studies typically had people fill in a questionnaire asking about their degree of belief in ESP and about any psi experiences they may have had. On the basis of their responses, participants were classified as either sheep or goats. All participants then took a standardized psi test, like an ESP card test, after which the results of the sheep and goats were compared. The idea was that the performance of the sheep would be significantly better than that of the goats. In 1993, psychologist Tony Lawrence from the University of Edinburgh, Scotland, reported a meta-analysis of all sheep-goat forced-choice experiments conducted between 1943 and 1993. Lawrence found seventy-three published reports by thirty-seven different investigators, involving more than 685,000 guesses produced by forty-five hundred participants. The overall results were strongly in favor of the sheep-goat effect, with believers performing better than disbelievers with odds greater than a trillion to one.

The atheist says we live in a random universe, he has no right to rely on inductive inference, he has no reason to expect causality, or simply the uniformity of nature. He has no basis for believing in the uniformity of nature, but if he has no basis for the uniformity of nature he has no basis for doing science, it's gone, kaput. Biology, chemistry, astronomy, psychology, history, grammar, all of it is gone, there are no sciences without inductive inference

Induction is the process of inferring generalizations from particular instances. The complementary process of applying generalizations to new instances is deduction. The theory of deductive reasoning was developed by Aristotle more than two millennia ago. This crucial achievement was a start toward understanding and validating knowledge, but it was only a start. Deduction presupposes induction; one cannot apply what one does not know or cannot conceive. The primary process of gaining knowledge that goes beyond perceptual data is induction. Generalization—the inference from some members of a class to all—is the essence of human cognition.

We have then many kinds of intuition; first, the appeal to the senses and the imagination; next, generalization by induction, copied, so to speak, from the procedures of the experimental sciences; finally, we have the intuition of pure number, whence arose the second of the axioms just enunciated, which is able to create the real mathematical reasoning.

TWO STYLES OF REASONING: PRINCIPLES-FIRST VERSUS APPLICATIONS-FIRST Principles-first reasoning (sometimes referred to as deductive reasoning) derives conclusions or facts from general principles or concepts. For example, we may start with a general principle like “All men are mortal.” Then we move to a more specific example: “Justin Bieber is a man.” This leads us to the conclusion, “Justin Bieber will, eventually, die.” Similarly, we may start with the general principle “Everything made of copper conducts electricity.” Then we show that the old statue of a leprechaun your grandmother left you is 100 percent copper. Based on these points, we can arrive at the conclusion, “Your grandmother’s statue will conduct electricity.” In both examples, we started with the general principle and moved from it to a practical conclusion. On the other hand, with applications-first reasoning (sometimes called inductive reasoning), general conclusions are reached based on a pattern of factual observations from the real world. For example, if you travel to my hometown in Minnesota one hundred times during January and February, and you observe every visit that the temperature is considerably below zero, you will conclude that Minnesota winters are cold (and that a winter visit to Minnesota calls for a warm coat as well as a scarf, wool hat, gloves, and ear warmers).

One idea that has been repeatedly tested is that low mood can make people better at analyzing their environments. Classic experiments by psychologists Lyn Abramson and Lauren Alloy focused specifically on the accuracy of people’s perceptions of their control of events, using test situations that systematically varied in how much control the subject truly had. In different conditions, subjects’ responses (pressing or not pressing a button) controlled an environmental outcome (turning on a green light) to varying degrees. Interestingly, subjects who were dysphoric (in a negative mood and exhibiting other symptoms of depression) were superior at this task to subjects who were nondysphoric (in a normal mood). Subjects who were in a normal mood were more likely to overestimate or underestimate how much control they had over the light coming on.7 Dubbed depressive realism, Alloy and Abramson’s work has inspired other, often quite sophisticated, experimental demonstrations of ways that low mood can lead to better, clearer thinking.8 In 2007 studies by Australian psychologist Joseph Forgas found that a brief mood induction changed how well people were able to argue. Compared to subjects in a positive mood, subjects who were put in a negative mood (by watching a ten-minute film about death from cancer) produced more effective persuasive messages on a standardized topic such as raising student fees or aboriginal land rights. Follow-up analyses found that the key reason the sadder people were more persuasive was that their arguments were richer in concrete detail (see Figure 2.2).9 In other experiments, Forgas and his colleagues have demonstrated diverse benefits of a sad mood. It can improve memory performance, reduce errors in judgment, make people slightly better at detecting deception in others, and foster more effective interpersonal strategies, such as increasing the politeness of requests. What seems to tie together these disparate effects is that a sad mood, at least of the garden variety, makes people more deliberate, skeptical, and careful in how they process information from their environment.

“
Going to Moscow was a dream for us,' Ilich said years later. He and his younger brother started the course within weeks of Soviet tanks rolling into Czechoslovakia to crush the heady 'Prague Spring'. But they soon found that discipline at the cosmopolitan university, whose 6000 students were all selected through the Communist Party of their country of origin, was as stifling as its modernist architecture. Drab grey concrete blocks squatted around a charmless artificial pond. The only dash of colour was a map of the world painted on to the façade of one block in a valiant attempt to symbolise the ideals of the university: from an open book, symbol of learning, a torch emerges, issuing multicoloured flames that spread like waves across the planisphere. Perhaps Ilich drew some comfort from glancing up at the mural as, huddled against the rigours of the Russian winter and wearing a black beret in tribute to Che Guevara who had died riddled by bullets in October of the previous year, he trudged across the bleak square on his way to lectures. Coincidentally, the base of the flame is very close to Venezuela.
Rules and regulations governed virtually every aspect of Ilich's life from the moment he started the first year's induction course, which was designed to flesh out his knowledge of the Russian language and introduce him to the delights of Marxist society before he launched into his chosen subjects, languages and chemistry. Like father, like son. Ilich rebelled against the rules, preferring to spend his time chasing girls. He would often crawl back to his room drunk. His professors at the university, some of them children of Spanish Civil War veterans who had sought refuge in Moscow, were unimpressed by his academic performance.
'His name alone, Ilich Ramírez Sánchez, was so strange that people were curious about him,' relates Kirill Privalov, a journalist on the newspaper Druzhba (Friendship) which was printed at the small university press, and an acquaintance of Ilich. The Venezuelan's escapades, wildly excessive by the standards of the university, only fanned people's interest. 'llich was not at all the typical student sent by his country's Communist Party, nothing to do with the good little soldier of Mao who laboured in the fields every summer. He was a handsome young man although his cheeks looked swollen, and he was a great bon viveur. Flush with cash sent by his parents, Ilich could afford to spend lavishly on whisky and champagne in the special stores that only accepted payment in hard currencies and which were off-limits to most people. More Russian than the Russians, the privileged student and his friends would throw over their shoulders not only empty glasses but bottles as well.
The university authorities, frustrated in their attempts to impose discipline on Ilich, reasoned that his freedom of action would be drastically limited if the allowance that his father sent him were reduced. But when they asked Ramírez Navas to be less generous, the father, piqued, retorted that his son had never wanted for anything. 'The university had a sort of vice squad, and at night students were supposed either to study or sleep,' recounts Privalov.
"One night the patrol entered Ilich's room and saw empty bottles of alcohol and glasses on the table, but he was apparently alone. The squad opened the cupboard door and a girl who was completely drunk fell out. She was naked and was clutching her clothes in her hands. They asked her what she was doing there and she answered: 'I feel pity for the oppressed.' She was obviously a prostitute. Another time, and with another girl, Ilich didn't bother to hide her in the cupboard. He threw her out of the window. This one was fully dressed and landed in two metres of snow a foor or two below. She got up unhurt and shouted abuse at him.

It’s a matter of balance between deduction and induction—between reason and empiricism—and in 1620 the English philosopher Francis Bacon published his Novum Organum, or “new instrument,” which described science as a blend of sensory data and reasoned theory. Ideally, Bacon argued, one should begin with observations, then formulate a general theory from which logical predictions can be made, then check the predictions against experiment.37 If you don’t give yourself a reality check you end up with half-baked (and often fully baked) ideas,

By noon, we had run almost every test we could do in our own small lab, and found one or two useless things. First, the basic broth was made from one of the commercially popular high-octane energy drinks. Human blood had been added in and, although it was difficult to be absolutely certain using the small and badly degraded sample, I was reasonably sure it had come from several sources. But the last ingredient, the organic something, remained elusive. “Okay,” I said at last. “Let’s go at this a different way.” “What,” Vince said, “with a Ouija board?” “Almost,” I said. “How about we try inductive logic?” “Okay, Sherlock,” he said. “More fun than gas chromatography any day.” “Eating your fellow humans is not natural,” I said, trying to put myself into the mind of someone at the party, but Vince interrupted my slow-forming trance. “What,” he said, “are you kidding?

Assuming that you already have the respect of your team members This is one of the most common mistakes made by rookie managers. They think that merely by the process of their being inducted into management, they have already garnered the respect o their team members. The truth is, the only way you will come to be admired and respected by your team member is by the way in which you ‘act’. You have to ‘earn’ your team’s respect by showing your character, integrity and your skills to do things. You have to show them that there is a reason that you are here in the first place; and only then will you get the respect and admiration you seek from them.

I would like to introduce a wonderful word to you, which will mean a great deal to your happiness. The word is "consciousness." It means the sum total of all your beliefs. Add up every thought or idea which you have ever accepted as true and that adds up to your state of beingness or consciousness. If you have accepted thoughts in the past which are not true, regarding who you are and what your relationship to other people is, then you have a consciousness of inferiority. You have that consciousness because you have accepted certain untrue things as though they were true. If you knew the truth about yourself you would not feel inferior, but you would jump up and down and shout. You would know that your Creator is richer than Henry Ford, and he is smarter than Einstein, and he is constantly looking after you day and night. You would know that you are very important. Now, how does one change his consciousness from a consciousness of inferiority to a consciousness of confidence in one's self. We must learn who we are and that we have an important role to play in the game of life. We must realize that we are indispensable channels of service to humanity. That we have both a conscious mind in a subconscious mind and that we reason both deductively and inductively

Hilbert does not build on the foundation of logic and arithmetic, but on the system of signs thereof; in the construction he uses the logic (syllogism from a general theorem for x) and the arithmetic (mathematical induction) as something meaningless and independent.
Moreover he presupposes as known the whole of mathematics as a guideline in the introduction of new symbols; and he employs subtle logical reasonings to convince us that he is on the right track.

Here is how a student at Smith College describes her induction into its call-out culture in the fall of 2014: During my first days at Smith, I witnessed countless conversations that consisted of one person telling the other that their opinion was wrong. The word “offensive” was almost always included in the reasoning. Within a few short weeks, members of my freshman class had quickly assimilated to this new way of non-thinking. They could soon detect a politically incorrect view and call the person out on their “mistake.” I began to voice my opinion less often to avoid being berated and judged by a community that claims to represent the free expression of ideas. I learned, along with every other student, to walk on eggshells for fear that I may say something “offensive.” That is the social norm here.

In the case a bricklayer working for a subcontractor on the Perth Stadium construction project suffered serious injuries when he single-handedly began to remove two overhead steel purlins that were in the way when he was building a wall. One of the discussions in the case was the extent to which the principal should have provided training to the subcontractor about workplace health and safety hazards associated with the work. In that context, the court observed: Pursuant to its contract, NeoWest had autonomy in how it was to complete the works and it was the appropriate body to provide the training and induction within its specialised area and to specify the methods to be used in performing the tasks required of its workers. It would not have been reasonably practicable, or indeed wise, for the first defendant to impinge on NeoWest's training and induction of its own employees as to the proper and safe method of completing the works within its scope of works and area of expertise and specialised knowledge, possibly to override or even contradict that training and induction. Each individual trade's expertise and specialist knowledge was the very reason why the first defendant engaged subcontractors to perform the various works in the first place, rather than complete them itself.60 This limited (although still very onerous) obligation is consistent with a social approach to managing wicked problems. As I argue later in the book, you cannot solve wicked problems – we cannot solve safety. All we can do is “tame” the problem of safety – do the best we can.

As Dr. Jung points out, the theory of the archetypes is by no means his own invention.[18] Compare Nietzsche: “In our sleep and in our dreams we pass through the whole thought of earlier humanity. I mean, in the same way that man reasons in his dreams, he reasoned when in the waking state many thousands of years....The dream carries us back into earlier states of human culture, and affords us a means of understanding it better.”[19] Compare Adolf Bastian’s theory of the ethnic “Elementary Ideas” (Elementargedanken), which, in their primal psychic character (corresponding to the Stoic Logoi spermatikoi), should be regarded as “the spiritual (or psychic) germinal dispositions out of which the whole social structure has been developed organically,” and, as such, should serve as bases of inductive research.[20] Compare Franz Boas: “Since Waitz’s thorough discussion of the question of the unity of the human species, there can be no doubt that in the main the mental characteristics of man are the same all over the world....Bastian was led to speak of the appalling monotony of the fundamental ideas of mankind all over the globe....Certain patterns of associated ideas may be recognized in all types of culture.”[21] Compare Sir James G. Frazer: “We need not, with some enquirers in ancient and modern times, suppose that the Western peoples borrowed from the older civilization of the Orient the conception of the Dying and Reviving God, together with the solemn ritual, in which that conception was dramatically set forth before the eyes of the worshippers. More probably the resemblance which may be traced in this respect between the religions of the East and West is no more than what we commonly, though incorrectly, call a fortuitous coincidence, the effect of similar causes acting alike on the similar constitution of the human mind in different countries and under different skies.”[22]

As another brilliant logician, Bertrand Russell, pointed out, Abelard tended to overrate the value of Aristotelian logic and of deduction as the only path to truth.

Reason for Abelard and his followers was a tool for understanding what was already known, especially about God and the Bible, not opening new vistas for human investigation.

Hume pointed out that human beings are inclined to accept inductive forms of reasoning and thus to take it for granted, in a way, that the future will relevantly resemble the past. As Hume also pointed out, however, it is hard to think of a good (noncircular) reason for believing that indeed the future will relevantly be like the past. Theisim, however, provides a reason: God has created us and our noetic capacities and has created the world; he has also created the former in such a way as to be adapted by the latter. It is likely, then, that he has created the world in such a way that indeed the future will indeed resemble the past in the relevant way.

However, we are prone to do the exact opposite: we under-deduce and over-induce.

Different cultures have different systems for learning in part because of the philosophers who influenced the approach to intellectual life in general and science in particular. Although Aristotle, a Greek, is credited with articulating applications-first thinking (induction), it was British thinkers, including Roger Bacon in the thirteenth century and Francis Bacon in the sixteenth century, who popularized these methodologies among modern scholars and scientists. Later, Americans, with their pioneer mentality and disinclination toward theoretical learning, came to be even more applications-first than the British. By contrast, philosophy on the European continent has been largely driven by principles-first approaches. In the seventeenth century, Frenchman René Descartes spelled out a method of principles-first reasoning in which the scientist first formulates a hypothesis, then seeks evidence to prove or disprove it. Descartes was deeply skeptical of data based on mere observation and sought a deeper understanding of underlying principles. In the nineteenth century, the German Friedrich Hegel introduced the dialectic model of deduction, which reigns supreme in schools in Latin and Germanic countries. The Hegelian dialectic begins with a thesis, or foundational argument; this is opposed by an antithesis, or conflicting argument; and the two are then reconciled in a synthesis.

There are several reasons why developing excellent dream recall is an essential prerequisite for learning lucid dreaming. First, when you remember your dreams well, you can become familiar with what they are actually like. Once you get to know your dreams really well, you will be in the position of recognizing them as dreams while they are still happening. Second, it is possible that with poor dream recall, you may actually have lucid dreams that you do not remember! Finally, as you will soon see, the most effective lucid dream induction method—the Mnemonic Induction of Lucid dreams (MILD) technique—requires you to remember more than one dream per night.

Deductive reasoning, the bedrock of the scientific method, begins with a new theory which leads to a prediction (a hypothesis). The real world is tested and observed to determine if the theory is supported. One can think of deduction as being top down or theory driven (or general to specific). Induction, on the other hand, begins with observations from the real world. Based on these observations, patterns are recognized and new theories proposed (specific to general). The different methods have important implications on model construction.

Chesterton's topic is nothing less than the fundamental contrast between deductive logic, true of all possible worlds, and inductive logic, capable only of telling us how we may reasonably expect this world to behave. Let us hasten to add that Chesterton's analysis is in full agreement with the views of modern logicians. Perhaps his "test of the imagination" is not strictly accurate--who can "imagine" the four-dimensional constructions of relativity?-but in essence his position is unassailable. Logical and mathematical statements are true by definition. They are "empty tautologies," to use a current phrase, like the impressive maxim that there are always six eggs in half a dozen. Nature, on the other hand, is under no similar constraints. Fortunately, her "weird repetitions," as GK calls them, often conform to surprisingly low-order equations. But as Hume and others before Hume made clear, there is no logical reason why she should behave so politely.

William James and most early psychologists were strongly influenced by British empiricism, which in turn is based on Christian philosophies. Under the empiricist framework, knowledge derives from the (human) brain’s ability to perceive and interpret the objective world. According to the empiricist philosopher David Hume,10 all our knowledge arises from perceptual associations and inductive reasoning to reveal cause-and-effect relationships.11 Nothing can exist in the mind without first being detected by the senses because the mind is built out of sensations of the physical world. He listed three principles of association: resemblance, contiguity in time and place, and causation.

"Jordan Peterson | The Most Terrifying IQ Statistic"
JORDAN PETERSON: One of the most terrifying statistics I ever came across was one detailing out the rationale of the United States Armed Forces for not allowing the induct … you can't induct anyone into the Armed Forces into the Armed Forces in the U.S. if they have an IQ of less than 83. Okay, so let's just take that apart for a minute, because it's a horrifying thing. So, the U.S. Armed Forces have been in the forefront of intelligence research since World War I because they were onboard early with the idea that, especially during war time when you are ramping up quickly that you need to sort people effectively and essentially without prejudice so that you can build up the officer corps so you don't lose the damned war, okay. So, there is real motivation to get it right, because it's a life-and-death issue, so they used IQ. They did a lot of the early psychometric work on IQ. Okay, so that's the first thing, they are motivated to find an accurate predictor, so they settled on IQ. The second thing was, the United States Armed Forces is also really motivated to get people into the Armed Forces, peacetime or wartime. Wartime, well, for obvious reasons. Peacetime, because, well, first of all you've got to keep the Armed Forces going and second you can use the Armed Forces during peacetime as a way of taking people out of the underclass and moving them up into the working class or the middle class, right. You can use it as a training mechanism, and so left and right can agree on that, you know. It's a reasonable way of promoting social mobility. So again, the Armed Forces even in peacetime is very motivated to get as many people in as they possibly can. And it's difficult as well. It's not that easy to recruit people, so you don't want to throw people out if you don't have to. So, what's the upshot of all that? Well, after one hundred years, essentially, of careful statistical analysis, the Armed Forces concluded that if you had an IQ of 83 or less there wasn't anything you could possibly be trained to do in the military at any level of the organization that wasn't positively counterproductive. Okay, you think, well, so what, 83, okay. Yeah, one in ten! One in ten! That's one in ten people! And what that really means, as far as I can tell, is if you imagine that the military is approximately as complex as the broader society, which I think is a reasonable proposition, then there is no place in our cognitively complex society for one in ten people. So what are we going to do about that? The answer is, no one knows. You say, "well, shovel money down the hierarchy." It's like, the problem isn't lack of money. I mean sometimes that's the problem, but the problem is rarely absolute poverty. It's rarely that. It is sometimes, but rarely. It's not that easy to move money down the hierarchy. So, first of all, it's not that easy to manage money. So, it's a vicious problem, man. And so...
INTERVIEWER: It's hard to train people to become creative, adaptive problem solvers.
PETERSON: It's impossible! You can't do it! You can't do it! You can interfere with their cognitive ability, but you can't do that! The training doesn't work.
INTERVIEWER: It's not going to work in six months, but it could have worked in six years.
PETERSON: No, it doesn't work. Sorry, it doesn't work. The data on that is crystal clear.
[note that “one in ten” applies to a breeding group with an average IQ of 100]

Justificationism, that is, the identification of knowledge with proven knowledge, was the dominant tradition in rational thought throughout the ages. Scepticism did not deny justificatonism: it only claimed that there was (and could be) no proven knowledge and therefore no knowledge whatsoever. For the sceptics 'knowledge' was nothing but animal belief. Thus justificationist scepticism ridiculed objective thought and opened the door to irrationalism, mysticism, superstition. This situation explains the enormous effort invested by classical rationalists in trying to save the synthetic a priori principles of intellectualism and by classical empiricists in trying to save the certainty of an empirical basis and the validity of inductive inference. For all of them "scientific honesty demanded that one assert nothing that is unproven." However, both were defeated: Kantians by non-Euclidean geometry and by non-Newtonian physics, and empiricists by the logical impossibility of establishing an empirical basis (as Kantians pointed out, facts cannot prove propositions) and of establishing an inductive logic (no logic can infallibly increase content). It turned out that all theories are equally unprovable. Philosophers were slow to recognize this, for obvious reasons: classi-cal justificationists feared that once they conceded that theoretical science is unprovable, they would have also to conclude that it is sophistry and illusion, a dishonest fraud. The philosophical import- ance of probabilism (or ' neojustificationism ') lies in the denial that such a conclusion is necessary.

“
If heights are to be scaled above man’s native power to achieve, then something more than guidance, however effective, is necessary. This is the reason for the super-induction, at the end of the long process of the production of Scripture, of the additional Divine operation which we call technically “inspiration”. By it, the Spirit of God, flowing confluently in with the providentially and graciously determined work of men, spontaneously producing under the Divine directions the writings appointed to them, gives the product a Divine quality unattainable by human powers alone.

Real faith and reason don’t fit the mold of traditional thinking but come from the person of Christ rather than a human viewpoint. And yet we need prayer to understand them since they come from a place totally different from the usual ineffective, weak, soft, inductive ways of thinking. Those old ways of thinking process thought but never come to the knowledge of the truth.

ethnic groups, but to say that we don’t divide each other into races would be to ignore thousands of years of human history. Not to mention the fact that white people drive a car like this: Fig. 3 While black people drive a car like this: Fig. 4 Despite increasing globalization and intermarriage, or “miscegenation,” there are still distinct and important differences between members of the different races. Since the subtlety and scope of those differences are far too complicated to be helpful to us in everyday life, we employ certain heuristics, or “stereotypes,” to better understand and more comfortably interact with those different from ourselves. Like the Maori. Such stereotypes are sometimes controversial, because they can oversimplify the differences between individuals. Every person is different, and it is rare for someone to fit a stereotype perfectly. Except for so-called “walking stereotypes,” like Carson from Queer Eye.2. Others don’t have any of the characteristics ascribed to their race in such stereotypes. It’s an imperfect science at best. For example, just because the Maori are, in general, lazy, selfish, and long-winded, that does not mean that noted Maori opera singer Kiri Te Kanawa is any of those things. In fact, she is only two of them, because she is a soprano, and sopranos tend to be very succinct. Even so, stereotypes can be very useful in our everyday social interactions and decision-making. They are actually a kind of survival instinct—a crude form of received inductive reasoning that can help us make snap judgments in situations where we don’t have all the facts. When entering into a business deal with someone of Roma descent, for instance, I am very careful of my possessions. Knowing the stereotype that gypsies are tramps and thieves,3. I am able to better protect myself when coming into contact with them,

Commodore Tariq Majeed, in a 1992 essay titled “Weaknesses and Limitations of Indian Naval Capability,” argues that India’s navy is inferior according to every metric used. One of his reasons for the Indian Navy’s ostensible inferiority to that of Pakistan is that it has been forced to induct women.
