Quotes about validity

“Eichmann, much less intelligent and without any education to speak of, at least dimly realized that it was not an order but a law which had turned them all into criminals. The distinction between an order and the Führer's word was that the latter's validity was not limited in time and space, which is the outstanding characteristic of the former. This is also the true reason why the Führer's order for the Final Solution was followed by a huge shower of regulations and directives, all drafted by expert lawyers and legal advisors, not by mere administrators; this order, in contrast to ordinary orders, was treated as a law. Needless to add, the resulting legal paraphernalia, far from being a mere symptom of German pedantry and thoroughness, served most effectively to give the whole business its outward appearance of legality.And just as the law in civilized countries assumes that the voice of conscience tells everybody, "Thou shalt not kill," even though man's natural desires and inclinations may at times be murderous, so the law of Hitler's land demanded that the voice of conscience tell everybody: "Thou shalt kill," although the organizers of the massacres knew full well that murder is against the normal desires and inclinations of most people. Evil in the Third Reich had lost the quality by which most people recognize it — the quality of temptation.”

“We are not talking here about a federal law prohibiting the States from regulating bubble-gum advertising, or even the construction of nuclear plants. We are talking about a federal law going to the core of state sovereignty: the power to exclude. […] The Court opinion’s looming specter of inutterable horror—‘[i]f [Section] 3 of the Arizona statute were valid, every State could give itself independent authority to prosecute federal registration violations’—seems to me not so horrible and even less looming. But there has come to pass, and is with us today, the specter that Arizona and the States that support it predicted: A Federal Government that does not want to enforce the immigration laws as written, and leaves the States’ borders unprotected against immigrants whom those laws would exclude. So the issue is a stark one. Are the sovereign States at the mercy of the Federal Executive’s refusal to enforce the Nation’s immigration laws? […] Arizona bears the brunt of the country’s illegal immigration problem. Its citizens feel themselves under siege by large numbers of illegal immigrants who invade their property, strain their social services, and even place their lives in jeopardy. Federal officials have been unable to remedy the problem, and indeed have recently shown that they are unwilling to do so. […] Arizona has moved to protect its sovereignty—not in contradiction of federal law, but in complete compliance with it. The laws under challenge here do not extend or revise federal immigration restrictions, but merely enforce those restrictions more effectively. If securing its territory in this fashion is not within the power of Arizona, we should cease referring to it as a sovereign State.”

“12 principles for a 21st century conservatism.
1. The fundamental assumptions of Western civilization are valid.
2. Peaceful social being is preferable to isolation and to war. In consequence, it justly and rightly demands some sacrifice of individual impulse and idiosyncrasy.
3. Hierarchies of competence are desirable and should be promoted. 
4. Borders are reasonable. Likewise, limits on immigration are reasonable. Furthermore, it should not be assumed that citizens of societies that have not evolved functional individual-rights predicated polities will hold values in keeping with such polities.
5. People should be paid so that they are able and willing to perform socially useful and desirable duties. 
6. Citizens have the inalienable right to benefit from the result of their own honest labor.
7. It is more noble to teach young people about responsibilities than about rights. 
8. It is better to do what everyone has always done, unless you have some extraordinarily valid reason to do otherwise.
9. Radical change should be viewed with suspicion, particularly in a time of radical change.
10. The government, local and distant, should leave people to their own devices as much as possible.
11. Intact heterosexual two-parent families constitute the necessary bedrock for a stable polity. 
12. We should judge our political system in comparison to other actual political systems and not to hypothetical utopias.”

Jordan Peterson (1962) Canadian clinical psychologist, cultural critic, and professor of psychology

“In Swami Dayananda's view, the term Arya was not coterminous with the term Hindu. The classical meaning of the word Arya is 'noble'. It is used as an honorific term of address, used in addressing the honoured ones in ancient Indian parlance. The term Hindu is reluctantly accepted as a descriptive term for the contemporary Hindu society and all its varied beliefs and practices, while the term Arya is normative and designates Hinduism as it ought to be…. Elsewhere in Hindu society, 'Arya' was and is considered a synonym for 'Hindu', except that it may be broader, viz. by unambiguously including Buddhism and Jainism. Thus, the Constitution of the 'independent, indivisible and sovereign monarchical Hindu kingdom' (Art.3:1) of Nepal take care to include the Buddhist minority by ordaining the king to uphold 'Aryan culture and Hindu religion' (Art.20: 1)…. The Arya Samaj's misgivings about the term Hindu already arose in tempore non suspecto, long before it became a dirty Word under Jawaharlal Nehru and a cause of legal disadvantage under the 1950 Constitution. Swami Dayananda Saraswati rightly objected that the term had been given by foreigners (who, moreover, gave all kinds of derogatory meanings to it) and considered that dependence on an exonym is a bit sub-standard for a highly literate and self-expressive civilization. This argument retains a certain validity: the self-identification of Hindus as 'Hindu' can never be more than a second-best option. On the other hand, it is the most practical choice in the short run, and most Hindus don't seem to pine for an alternative.”

“Let me start a different/ analysis by recalling an idea from Max Weber. He characterized cultural modernity as the separation of the substantive reason expressed in religion and metaphysics into three autonomous spheres. They are science, morality and art. These came to be differentiated because the unified world-views of religion and metaphysics fell apart. Since the 18th century, the problems inherited from these older world-views could be arranged so as to fall under specific aspects of validity: truth, normative rightness, authenticity and beauty. They could then be handled as questions of knowledge, or of justice and morality, or of taste. Scientific discourse, theories of morality, Jurisprudence, and the production and criticism of art could in turn be institutionalized. Each domain of culture could be made to correspond to cultural professions in which problems could be dealt with as the concern of special experts. This professionalized treatment of the cultural tradition brings to the fore the intrinsic structures of each of the three dimensions of culture. There appear the structures of cognitive-instrumental, of moral-practical and of aesthetic-expressive rationality, each of these under the control of specialists who seem more adept at being logical in these particular ways than other people are. As a result, the distance grows between the culture of the experts and that of the larger public. What accrues to culture through specialized treatment and reflection does not immediately and necessarily become the property of everyday praxis. With cultural rationalization of this sort, the threat increases that the life-world, whose traditional substance has already been devalued, will become more and more impoverished.”

“There are two dominant mindsets in the world of business or any kind of organization.One is a productive mindset, and it says it's a good idea to seek valid knowledge, it's a good idea to craft your conversations so you make explicit what you are thinking and trying to examine. You craft them in such a way that you can test, as clearly as you can, the validity of your claims. Truth is a good idea. All the managerial functions—accounting, all of them—have a fundamental notion that the productive mindset is what ought to be used to manage human beings.Then there's another mindset I call the defensive mindset. The idea is that even if you are seeking valid knowledge, you are seeking only that kind of valid knowledge that protects yourself or your organization or your department—it is defensive. From a defensive mindset point of view, truth is a good idea when it isn't threatening or upsetting. If it is, massage it, spin it. But if you massage it and spin it, you're violating the espoused theory of good management. When you spin, you have to cover up the fact that you're spinning. And in order for a cover up to work, it too has to be covered up.”

“They [laboratory groups] bypass such questions as how one comes to know that a problem exists, what it does to solution adequacy to be working on several different things concurrently with problem solving, what it's like to go about solving a felt, intuited problem rather than an explicitly stated consensually validated problem which was made visible to all members at a specific point in time.”

“A pattern of basic assumptions--invented, discovered, or developed by a given group as it learns to cope with its problems of external adaptation and internal integration--that has worked well enough to be considered valid and, therefore, to be taught to new members as the correct way to perceive, think, and feel in relation to those problems.”

Edgar H. Schein (1928) Psychologist

Variant: [ Organizational culture is] a pattern of shared basic assumptions that the group learned as it solved its problems of external adaptation and internal integration, that has worked well enough to be considered valid and, therefore, to be taught to new members as the correct way to perceive, think, and fell in relation to those problems.

“Physiologic facts concerning the origin of species in nature were unknown in the time of Darwin... The experience of the breeders was quite inadequate to the use which Darwin made of it. It was neither scientific, nor critically accurate. Laws of variation were barely conjectured; the different types of variability were only imperfectly distinguished. The breeders' conception was fairly sufficient for practical purposes, but science needed a clear understanding of the factors in the general process of variation. Repeatedly Darwin tried to formulate these causes, but the evidence available did not meet his requirements.
Quetelet's law of variation had not yet been published. Mendel's claim of hereditary units for the explanation of certain laws of hybrids discovered by him, was not yet made. The clear distinction between spontaneous and sudden changes, as compared with the ever-present fluctuating variations, is only of late coming into recognition by agriculturists. Innumerable minor points which go to elucidate the breeders' experience, and with which we are now quite familiar, were unknown in Darwin's time. No wonder that he made mistakes, and laid stress on modes of descent, which have since been proved to be of minor importance or even of doubtful validity.”

“What are wanted for the Indian as for the Englishman, the Frenchman, the German, and the Russian, are not Constitutions and Revolutions, nor all sorts of Conferences and Congresses, nor the many ingenious devices for submarine navigation and aerial navigation, nor powerful explosives, nor all sorts of conveniences to add to the enjoyment of the rich, ruling classes; nor new schools and universities with innumerable faculties of science, nor an augmentation of papers and books, nor gramophones and cinematographs, nor those childish and for the most part corrupt stupidities termed art — but one thing only is needful: the knowledge of the simple and clear truth which finds place in every soul that is not stupefied by religious and scientific superstitions — the truth that for our life one law is valid — the law of love, which brings the highest happiness to every individual as well as to all mankind. Free your minds from those overgrown, mountainous imbecilities which hinder your recognition of it, and at once the truth will emerge from amid the pseudo-religious nonsense that has been smothering it: the indubitable, eternal truth inherent in man, which is one and the same in all the great religions of the world. It will in due time emerge and make its way to general recognition, and the nonsense that has obscured it will disappear of itself, and with it will go the evil from which humanity now suffers.”

“Depersonalization is a concept difficult to delineate. It can be regarded as a symptom or as a loosely associated group of symptoms that occurs in psychiatric patients. It can be induced experimentally and also occurs spontaneously in normal subjects. A major obstacle to clearer definition of this concept lies in the fact that it refers to exceedingly private events in the individual's experience. These prove very difficult to describe by a language geared to the description of public (consensually validated) events or private events, such as pain, that occur usually in clearly defined social settings. When it comes to describing and conveying something as ineffable as depersonalization or derealization, the subject resorts to metaphors, "as if" expressions, and figures of speech. The result is semantic confusion. Different authors mean different things when they use the term depersonalization.
The concept of depersonalization merges by imperceptible degrees with the concept derealization, the concept of altered body image and self, deja vu, jamais vu, altered time and space perception and so on - the whole gamut of phenomenological description of the experiences of mental patients. Therefore, it is rather difficult to evaluate and to review objectively the psychiatric literature on the phenomena of depersonalization.”

“The reality of the situation is obscured when population is expressed as a percentage proportion taken over the whole of the United Kingdom. The ethnic minority is geographically concentrated, so that areas in which it forms a majority already exists, and these areas are destined inevitably to grow. It is here that the compatibility of such an ethnic minority with the functioning of parliamentary democracy comes into question. Parliamentary democracy depends at all levels upon the valid acceptance of majority decision, by which the nation as a whole is content to be bound because of the continually available prospect that what one majority has decided another majority can subsequently alter. From this point of view, the political homogeneity of the electorate is crucial. What we do not, as yet, know is whether the voting behaviour of our altered population will be able to use the majority vote as a political instrument and not as a means of self-identification, self-assertion and self-enumeration. It may be that the United Kingdom will escape the political consequences of communalism; but communalism and democracy, as the experience of India demonstrates, are incompatible. That is the spectre which the Conservative party's policy of assisted repatriation in the 1960s aimed to banish; but time and events have swept over and passed the already outdated remedies of the 1960s. We are entering unknown territory where the only certainty for the future is the relative increase of the ethnic minority due to the age structure of that population which has been established.”
