“I have this theory about smart people. If you’re smart, you’re either the only person in your family who’s smart, or everybody in the family is smart. No in-between.”

Douglas Coupland book JPod

I considered this. “I think I come from the everybody’s smart category. But they don’t apply their smarts to… larger picture pursuits. That includes me.”

“There is a certain amount of sham in shamanism. There is a certain amount of theatre. It’s as loosely knit as that. We’re sort of coming out of the closet a bit more over the next couple of years. We’re going to be bringing out – manifesto’s too pushy a word – if it’s a theatre of marvels, we’re bringing out a theatre programme in the next couple of years. We’re working on it at the moment – our unified field theory of spookiness where we try to explain everything from language, consciousness, grey aliens to Rosicrucianism or whatever. It is a grand, mad theory which I’m working my best on at the moment to make it rational. It is an anti-rationalistic theory but I’m trying to couch it in rational terms so that it is not as insular as a lot of magic stuff.”

“The job of theorists, especially in biology, is to suggest new experiments. A good theory makes not only predictions, but surprising predictions that then turn out to be true.”

“My father was as well aware as anyone that Christians do not, in general, undergo the demoralizing consequences which seem inherent in such a creed, in the manner or to the extent which might have been expected from it. The same slovenliness of thought, and subjection of the reason to fears, wishes, and affections, which enable them to accept a theory involving a contradiction in terms, prevents them from perceiving the logical consequences of the theory. Such is the facility with which mankind believe at one and the same time things inconsistent with one another, and so few are those who draw from what they receive as truths, any consequences but those recommended to them by their feelings, that multitudes have held the undoubting belief in an Omnipotent Author of Hell, and have nevertheless identified that being with the best conception they were able to form of perfect goodness.”

“A sane society would be asking questions about the very nature of a society and culture that creates so much trauma for children.... We live in a society that prioritizes profits for large corporations and power for large institutions. We live in a society in which, for example, the cause of depression and suicide has been, for decades, falsely attributed by psychiatry and Big Pharma to a chemical imbalance theory long known to be untrue—an untruth that has made billions of dollars for drug companies and increased power for psychiatry through increased use of antidepressants which are known to actually increase suicide... just one of many examples that we do not live in a sane society.”

“A scientific theory is usually felt to be better than its predecessors not only in the sense that it is a better instrument for discovering and solving puzzles but also because it is somehow a better representation of what nature is really like. One often hears that successive theories grow ever closer to, or approximate more and more closely to, the truth. Apparently generalizations like that refer not to the puzzle-solutions and the concrete predictions derived from a theory but rather to its ontology, to the match, that is, between the entities with which the theory populates nature and what is “really there.””

Thomas Kuhn book The Structure of Scientific Revolutions

Perhaps there is some other way of salvaging the notion of ‘truth’ for application to whole theories, but this one will not do. There is, I think, no theory-independent way to reconstruct phrases like ‘really there’; the notion of a match between the ontology of a theory and its “real” counterpart in nature now seems to me illusive in principle. Besides, as a historian, I am impressed with the implausability of the view. I do not doubt, for example, that Newton’s mechanics improves on Aristotle’s and that Einstein’s improves on Newton’s as instruments for puzzle-solving. But I can see in their succession no coherent direction of ontological development. On the contrary, in some important respects, though by no means in all, Einstein’s general theory of relativity is closer to Aristotle’s than either of them is to Newton’s.

“Aggregation means the organization of elements of a system into patterns that tend to put highly compatible elements together and less compatible elements apart. Landscape theory predicts how aggregation will lead to alignments among actors (such as nations), whose leaders are myopic in their assessments and incremental in their actions. The predicted configurations are based upon the attempts of actors to minimize their frustration based upon their pairwise propensities to align with some actors and oppose others. These attempts lead to a local minimum in the energy landscape of the entire system. The theory is supported by the results of the alignment of seventeen European nations in the Second World War. The theory has potential for application to coalitions of business firms, political parties in parliaments, social networks, social cleavages in democracies, and organizational structures.”

“Throughout the social sciences today, the dominant form of modeling is based upon the rational-choice paradigm. Game theory, in particular, is typically based upon the assumption of rational choice. In my view, the reason for the dominance of the rational-choice approach is not that scholars think it is realistic. Nor is game theory used solely because it offers good advice to a decision maker, because its unrealistic assumptions undermine much of its value as a basis for advice.”

“Our ignorance of brain function is currently so very nearly total that we could not even begin to frame appropriate research strategies. We would stand before the open brain, fancy instruments in hand, roughly as an unschooled labourer might stand before the exposed wiring of a computer: awed perhaps, but surely helpless. A microanalysis of brain functions is, moreover, no more useful for understanding anything about thinking than a corresponding analysis of the pulses flowing through a computer would be for understanding what program the computer is running. Such analyses would simply be at the wrong conceptual level. They might help to decide crucial experiments, but only after such experiments had been designed on the basis of much higher-level (for example, linguistic) theories.”

“Because practice is subjective, theory which is always the theory of an object, can't access to the reality of this practice, what it is in itself, but only represent it, in such a way that this representation lets out of itself the real being of practice, the effectivity of the doing. Theory does nothing.”

“The theory of the nature of mathematics is extremely reactionary. We do not subscribe to the fairly recent notion that mathematics is an abstract language based, say, on set theory. In many ways, it is unfortunate that philosophers and mathematicians like Russell and Hilbert were able to tell such a convincing story about the meaning-free formalism of mathematics. In Greek, mathematics simply meant learning, and we have adapted this... to define the term as "learing to decide."”

C. West Churchman (1913–2004) American philosopher and systems scientist

Mathematics is a way of preparing for decisions through thinking. Sets and classes provide one way to subdivide a problem for decision preparation; a set derives its meaning from decision making, and not vice versa.

“The influence of literary theory on its related disciplines has prompted much debate about the notion of ‘authorship’. Yet the attraction of exploring architecture, or more specifically a building, through the life of its architect (author) remains a significant force in the construction of its histories. This is particularly the case when the architect has been identified as a major figure in the evolution of the architectural history. Conversely, buildings without architects are pushed to the sidelines of history.”

“Property rights are not like other rights, contrary to what Madison and a lot of modern political theory says. If I have the right to free speech, it doesn't interfere with your right to free speech. But if I have property, that interferes with your right to have that property, you don't have it, I have it. So the right to property is very different from the right to freedom of speech. This is often put very misleadingly about rights of property; property has no right. But if we just make sense out of this, maybe there is a right to property, one could debate that, but it's very different from other rights.”

“The 1918 flu almost certainly didn’t originate in Spain. One popular theory for how it acquired the “Spanish” name posits that Spain was the only country where you could read about the disease. That’s because Spain remained neutral during World War I, and therefore its newspapers weren’t censoring any information deemed harmful to national morale. The disease was also rampaging through other countries, including France, Germany, Britain, and the United States, but those governments suppressed or downplayed reports on the extent of the damage. Accurate and timely information is vital to combating a pandemic, but still, some countries’ first impulses are to cover up the spread of the disease.”

“When the Löwenheim-Skolem theorem is applied to particular formal systems, we obtain as special cases: Every group, field, ordered field, etc., has a countable subsystem of the same type. A more spectacular result follows from applying the theorem to set theory (a system which we shall later formalize): There is a countable collection of sets, such that if restrict the membership relation to these sets alone, they form a model for set theory (more precisely all the true statements of set theory are true in this model). In particular, within this model which we may denote by M, there must be an uncountable set. This paradox, that a countable model can contain an uncountable set, is explained by noting that to say a set is uncountable merely asserts the nonexistence of a one-one mapping of the set with the set of integers. The "uncountable" set in M set actually has only countably many members in M, but there is no one-one correspondence \underline {within} M of this set with the set of integers.”

“All change is relative. The universe is expanding relatively to our common material standards; our material standards are shrinking relatively to the size of the universe. The theory of the "expanding universe" might also be called the theory of the "shrinking atom."”

Arthur Stanley Eddington (1882–1944) British astrophysicist

[…] Let us then take the whole universe as our standard of constancy, and adopt the view of a cosmic being whose body is composed of intergalactic spaces and swells as they swell. Or rather we must now say it keeps the same size, for he will not admit that it is he who has changed. Watching us for a few thousand million years, he sees us shrinking; atoms, animals, planets, even the galaxies, all shrink alike; only the intergalactic spaces remain the same. The earth spirals round the sun in an ever‑decreasing orbit. It would be absurd to treat its changing revolution as a constant unit of time. The cosmic being will naturally relate his units of length and time so that the velocity of light remains constant. Our years will then decrease in geometrical progression in the cosmic scale of time. On that scale man's life is becoming briefer; his threescore years and ten are an ever‑decreasing allowance. Owing to the property of geometrical progressions an infinite number of our years will add up to a finite cosmic time; so that what we should call the end of eternity is an ordinary finite date in the cosmic calendar. But on that date the universe has expanded to infinity in our reckoning, and we have shrunk to nothing in the reckoning of the cosmic being.
We walk the stage of life, performers of a drama for the benefit of the cosmic spectator. As the scenes proceed he notices that the actors are growing smaller and the action quicker. When the last act opens the curtain rises on midget actors rushing through their parts at frantic speed. Smaller and smaller. Faster and faster. One last microscopic blurr of intense agitation. And then nothing.

The perils of change are so great the promise of the most hopeful theories is so often deceptive, that it is frequently the wiser part to uphold the existing state of things, if it can be done, even though, in point of argument, it should be utterly indefensible.”

“Both Stoicism and Epicureanism — the apathetic acceptance of defeat, and the effort to forget defeat in the arms of pleasure — were theories as to how one might yet be happy though subjugated or enslaved; precisely as the stoicism of Schopenhauer and the despondent epicureanism of Renan were in the nineteenth century the symbols of a shattered revolution and a broken France.”

“Even in physics, there is no infallible procedure for generating reliable knowledge. The calm order and perfection of well-established theories, accredited by innumerable items of evidence from a thousand different hands, eyes and brains, is not characteristic of the front-line of research, where controversy, conjecture, contradiction and confusion are rife. The physics of undergraduate text-books is 90% true; the contents of the primary research journals of physics is 90% false. The scientific system is as much involved in distilling the former out of the latter as it is in creating and transferring more and more bits of data and items of 'information'.”

“Unlike utilitarianism, republican theory does not take people's existing preferences, whatever they may be, and try to satisfy them. It seeks instead to cultivate in citizens the qualities of character necessary to the common good of self-government. Insofar as certain dispositions, attachments, and commitments are essential to the realization of self-government, republican politics regards moral character as a public, not merely private, concern. In this sense, it attends to the identity, not just the interests, of its citizens.”

“I suggest that scientific knowledge, though logically more articulate and far more complex, is of this sort. The books and teachers from whom it is acquired present concrete examples together with a multitude of theoretical generalizations. Both are essential carriers of knowledge, and it is therefore Pickwickian to seek a methodological criterion that supposes the scientist can specify in advance whether each imaginable instance fits or would falsify his theory.”

“The only way to have real success in science, the field I'm familiar with, is to describe the evidence very carefully without regard to the way you feel it should be.

“Because physical theories typically predict numerical values, an improvement in experimental precision reduces the tolerance range and hence increases corroborability. In most psychological research, improved power of a statistical design leads to a prior probability approaching ½ of finding a significant difference in the theoretically predicted direction. Hence the corroboration yielded by "success" is very weak, and becomes weaker with increased precision. "Statistical significance" plays a logical role in psychology precisely the reverse of its role in physics. This problem is worsened by certain unhealthy tendencies prevalent among psychologists, such as a premium placed on experimental "cuteness" and a free reliance upon ad hoc explanations to avoid refutation.”

“It is known that very distant nebulae, probably galactic systems like our own, show remarkably high receding velocities whose magnitude increases with the distance. This curious phenomenon promises to provide some important clues for the future development of our cosmological views. It maybe of advantage, therefore, to point out some of the principal facts which any cosmological theory will have to account for. Then a brief discussion will be given of different theoretical suggestions related to the above effect. Finally, a new effect of masses upon light will be suggested which is a sort of gravitational analogue of the Compton effect.”
