Mapping
No map represents all of its intended territory [...] Every map is at least a map of the map-maker (his assumptions, world-view...)
**
A map is not the territory it represents, but, if correct, it has a similar structure to the territory, which accounts for its usefulness. If the map could be ideally correct, it would include, in a reduced scale, the map of the map; the map of the map of the map; and so on, endlessly, a fact first noticed by [Josiah] Royce. If we reflect upon our languages, we find that at best they must be considered only as maps. A word is not the object it represents; and languages exhibit also this peculiar self-reflexiveness, that we can analyze languages by linguistic means.

Language Corrections
Essentially PC [Politic Correctness] is a correction from language that developed in an oppressive context and achieved mainstream usage, Doublespeak must be corrected in order to understand what is really being said. Both concepts can be said to use euphemism as their mechanism, but there's an important distinction. PC uses value neutral terms to replace inherently and unfairly derogatory ones. Doublespeak uses ironic terms to hide their motives and cynically cast them as the opposite. If I speak of sex workers rather than "whores" it is not because I am trying to hide any truth about them. It is that the "acceptable" term holds no deeper truth and only insult. If I speak of "creative bookkeeping" rather than theft, I am trying to hide or minimize guilt. @absurdistwords

Reifying Ghosts
Belief in the existence of 'stochastic processes' in the real world; i.e. that the property of being 'stochastic' rather than 'deterministic' is a real physical property of a process, that exists independently of human information, is another example of the mind projection fallacy: attributing one's own ignorance to Nature instead. The current literature of probability theory is full of claims to the effect that a 'Gaussian random process' is fully determined by its first and second moments. If it were made clear that this is only the defining property for an abstract mathematical model, there could be no objection to this; but it is always presented in verbiage that implies that one is describing an objectively true property of a real physical process. To one who believes such a thing literally, there could be no motivation to investigate the causes more deeply than noting the first and second moments, and so the real processes at work might never be discovered.

scientific discovery is not a one-step process
To counter this universal tendency of the untrained mind to see causal relations and trends where none exist, responsible science requires a very skeptical attitude, which demands cogent evidence for an effect; particularly one which has captured the popular imagination. Thus we can easily understand and sympathize with the orthodox conservatism in accepting new effects. There is another side to this; skepticism can be carried too far. The orthodox bias against a real effect does help to hold irresponsibility in check, but today it is also preventing recognition of effects that are real and important.
The history of science offers many examples of important discoveries that had their origin in the perception of someone who saw a small unexpected thing in his data, that an orthodox significance test would have dismissed as a random error. Jeffreys (1939, p. 321) notes that there has never been a time in the history of gravitational theory when an orthodox significance test, which takes no note of alternatives, would not have rejected Newton's law and left us with no law at all. Nevertheless, Newton's law did lead to constant improvements in the accuracy of our accounting of the motions of the moon and planets for centuries, and it was only when an alternative (Einstein's law) had been stated fully enough to make very accurate known predictions of its own that a rational person could have thought of abandoning Newton's law. The discovery of argon by Lord Rayleigh and of cosmic rays by Victor Hess are examples that come to mind immediately. Of course, they did not jump to sweeping conclusions from a single observation, as do the disaster-mongers; rather, they used the single surprising observation to motivate a careful investigation that culminated in overwhelming evidence for the new phenomenon.
It is fortunate that physicists and astronomers do not, in practice, use orthodox significance tests; their own innate common sense is a safer and more powerful reasoning tool. In other fields we must wonder how many important discoveries, particularly in medicine, have been prevented by editorial policies which refuse to publish that necessary first evidence for some effect, because the one data set that the researcher was able to obtain did not quite achieve an arbitrarily imposed significance level in an orthodox test. This could well defeat the whole purpose of scientific publication; for the cumulative evidence of three or four such data sets might have yielded overwhelming evidence for the effect. Yet this evidence may never be found unless the first data set can manage to get published. How can editors recognize that scientific discovery is not a one-step process, but a many step one, without thereby releasing a new avalanche of irresponsible, sensational publicity seekers? The problem is genuinely difficult, and we do not pretend to know the full answer. (p.504ff) Probability Theory, The Logic of Science, E.T.Jaynes

the pull and push of ethical systems
Intuitively, there are two basic desiderata for a system of ethics:
- that the system prescribes behaving well toward other people, or prescribes behaving with respect for certain principles; and
- that the system provides a rationally compelling reason to behave as it prescribes.

the uninsurable future
In Limits
to Growth, the groundbreaking study of future resource and
capital flows, the authors noted that what will ultimately halt growth is
not lack of resources, but the dedication of all investable capital to maintaining
the existing system. This will leave no capital for expanding the
size of the economy. Rising insurance and rebuilding costs [from climate change, from aggregate infrastructure complexity] are becoming a
major destination for capital that would otherwise go towards producing
economic growth. This is moving us ever closer to outcome
suggested by the Limits to Growth researchers. -- Climate change and the uninsurable future Kurt Cobb

As soon as we die, we enter into fiction
Evidence is always partial. Facts are not truth, though they are part of it – information is not knowledge. And history is not the past – it is the method we have evolved of organising our ignorance of the past. It’s the record of what’s left on the record. It’s the plan of the positions taken, when we to stop the dance to note them down. It’s what’s left in the sieve when the centuries have run through it – a few stones, scraps of writing, scraps of cloth. It is no more “the past” than a birth certificate is a birth, or a script is a performance, or a map is a journey. It is the multiplication of the evidence of fallible and biased witnesses, combined with incomplete accounts of actions not fully understood by the people who performed them. It’s no more than the best we can do, and often it falls short of that. -- why I became a historical novelist Hilary Mantel

Biological Causes
Modern biology is characterized by a number of ideological prejudices that shape the form of its explanations and the way its researches are carried out. One of those major prejudices is concerned with the nature of causes. Generally one looks for the cause of an effect, or even if there are a number of causes allowed, one supposes that there is a major cause and the others are only subsidiary. And in any case, these causes are separated from each other, studied independently, and manipulated and interfered with in an independent way. Moreover, these causes are usually seen to be at an individual level, the individual gene or the defective organ or an individual human being who is the focus of internal biological causes and external causes from an autonomous nature.
This view of causes is nowhere more evident than in our theories of health and disease. Any textbook of medicine will tell us that the cause of tuberculosis is the tubercle bacillus, which gives us the disease when it infects us. Modern scientific medicine tells us that the reason we no longer die of infectious diseases is that scientific medicine, with its antibiotics, chemical agents, and high-technology methods of caring for the sick, has defeated the insidious bacterium. What is the cause of cancer? The cause is the unrestricted growth of cells. That runaway growth, in turn, is a consequence of the failure of certain genes to regulate cell division. So we get cancer because our genes are not doing their business. It used to be that people thought that viruses were a major cause of cancer, and a great deal of money and time has been spent looking for the viral causes of cancer in humans without success. Biology has moved on from the time when viruses were all the rage to a time when genes are much more trendy.
Alternatively, there are environmental insult theories of the causes of cancer. Cancers are caused, we are told, by asbestos or by PVC or by a host of natural chemicals over which we have no control, and although they are present in very low concentrations, we are exposed to them over our whole lives. So, just as we will avoid dying from tuberculosis by dealing with the bug that causes it, so we will avoid dying from cancer by getting rid of particularly nasty chemicals in the environment. It is certainly; true that one cannot get tuberculosis without a tubercle bacillus, and the evidence is quite compelling that one cannot get the cancer mesothelioma without having ingested asbestos or related compounds. But that is not the same as saying that the cause of tuberculosis is the tubercle bacillus and the cause of mesothelioma is asbestos. What are the consequences for our health of thinking in this way? Suppose we note that tuberculosis was a disease extremely common in the sweatshops and miserable factories of the nineteenth century, whereas tuberculosis rates were much lower among country people and in the upper classes. Then we might be justified in claiming that the cause of tuberculosis is unregulated industrial capitalism, and if we did away with that system of social organization, we would not need to worry about the tubercle bacillus. When we look at the history of health and disease in modern Europe, that explanation makes at least as good sense as blaming the poor bacterium. -- Biology as Ideology, Richard Lewontin

Dogmas Everywhere
We're all familiar with prudishness as it applies to sexual ethics: the prude thinks certain sex acts are immoral, even between happily consenting adults. They also hold that sex work is inherently degrading, and that others should not be allowed to offer monetary compensation in exchange for one's sexual labour. The prude is not willing to tolerate others engaging in consensual and mutually beneficial exchanges in this arena if they don't stem from what the prude regards as the "right" motivations and take place within "approved" institutional arrangements (e.g. marriage). It's a deeply illiberal perspective that has thankfully fallen out of favour in recent decades. We may, of course, have reasonable concerns about the exploitation of sex workers in practice. But it's increasingly recognized that the best response to such practical concerns is to improve the options available to those in desperate circumstances, not to deprive them of (what they evidently regard as) their current best option. So I think it's fair to say that liberals have won out over sexual prudes in our current cultural milieu.
Sadly, the reverse appears true within the arena of research ethics. Research prudes think that certain kinds of medical research (e.g. involving voluntary infection) are unethical, even when all involved are happily consenting adults. They disapprove of offering monetary compensation to research participants, to make participation worth one's while when it otherwise would not be. They are not willing to tolerate others' engaging in consensual and mutually beneficial research arrangements if participation doesn't stem from what the research prude regards as the "right" (i.e. non-financial) motivations. It's a deeply illiberal view that unfortunately still predominates, with cultural bastions like the New York Times routinely dismissing controversial ("queer") research possibilities as "unethical", without argument. We may, of course, have reasonable concerns about the exploitation of research participants in practice. But it's depressing how hastily people assume that the best response to such concerns is to paternalistically deprive others of an option that they might well have reasonably preferred over their available alternatives.
Perhaps the most important difference between the two arenas is that the research prude's illiberalism is vastly more harmful. Medical research has immense positive externalities. So preventing it has immense negative externalities. You're not just harming the would-be research participants (not to mention undermining their autonomy), you're also harming all those who end up suffering from medical conditions that could have been cured or prevented had the research gone ahead. Missed opportunities are rarely salient, and so do not provoke the outrage that they truly deserve. But on any reasonable estimate, the death toll of research prudishness is surely monstrous. -- Against Prudish Research Ethics, Richard Y Chappell

Bullshit Jobs
Would-be capitalists were not granted the right to create limited-liability corporations unless they could prove doing so would constitute a clear and incontestable "public benefit" (in other words, the notion of social value not only existed but was inscribed in law) [...] much of this anticapitalist feeling was justified on religious grounds; popular Protestantism, drawing on its Puritan roots, not only celebrated work, but embraced the belief that, as my fellow anthropologists Dimitra Doukas and Paul Durrenberger have put it, "work was a sacred duty and a claim to moral and political superiority over the idle rich" [...] work was both a value in itself and the only real producer of value.
In the immediate wake of the Civil War all this began to change with the first stirrings of large-scale bureaucratic, corporate capitalism. The "Robber Barons," as the new tycoons came to be called, were at first met (as the name given them implies) with extraordinary hostility. But by the 1890s they embarked on an intellectual counteroffensive [...] The promulgation of consumerism also coincided with the beginnings of the managerial revolution, which was, especially at first, largely an attack on popular knowledge. Where once hoopers and wainwrights and seamstresses saw themselves as heirs to a proud tradition, each with its secret knowledge, the new bureaucratically organized corporations and their "scientific management" sought as far as possible to literally turn workers into extensions of the machinery, their every move predetermined by someone else.
Why was this campaign so successful? Because it cannot be denied that, within a generation, "producerism" had given way to "consumerism," the "source of status," as Harry Braverman put it, was "no longer the ability to make things but simply the ability to purchase them", and the labor theory of value—which had, meanwhile, been knocked out of economic theory by the "marginal revolution"—had so fallen away from popular common sense that nowadays, only graduate students or small circles of revolutionary Marxist theorists are likely to have heard of it. Nowadays, if one speaks of "wealth producers," people will automatically assume one is referring not to workers but to capitalists.
This was a monumental shift in popular consciousness. What made it possible? It seems to me that the main reason lies in a flaw in the original labor theory of value itself. This was its focus on "production" [...] which was always conceived primarily as male work — as a matter of making and building things, or perhaps coaxing them from the soil, while for women "labor" was seen primarily and emblematically as a matter of producing babies. Most real women’s labor disappeared from the conversation [...] "Caring labor" is generally seen as work directed at other people, and it always involves a certain labor of interpretation, empathy, and understanding. To some degree, one might argue that this is not really work at all, it’s just life, or life lived properly—humans are naturally empathetic creatures, and to communicate with one another at all, we must constantly cast ourselves imaginatively into each other’s shoes and try to understand what others are think ing and feeling, which usually means caring about them at least a little—but it very much becomes work when all the empathy and imaginative identification is on one side. The key to caring labor as a commodity is not that some people care but that others don’t; that those paying for "services" (note how the old feudal term is still retained) feel no need to engage in interpretive labor themselves.
[...] as many feminist economists have pointed out, all labor can be seen as caring labor, since even if one builds a bridge, it’s ultimately because one cares about people who might wish to cross the river. As the examples I cited at the time make clear, people do really think in these terms when they reflect on the "social value" of their jobs.

Small Telescopes
It is generally very difficult to prove that something does not exist; it is considerably easier to show that a tool is inadequate for studying that something. With a small-telescopes approach, instead of arriving at the conclusion that a theoretically interesting effect does not seem to exist, we arrive at the conclusion that the original evidence suggesting a theoretically interesting effect exists does not seem to be adequate. -- Uri Simonsohn

Man's Search For Meaning
There is much wisdom in the words of Nietzsche: "He who has a why to live for can bear almost any how."
[...] mental health is based on a certain degree of tension, the tension between what one has already achieved and what one still ought to accomplish, or the gap between what one is and what one should become. Such a tension is inherent in the human being and therefore is indispensable to mental well-being. We should not, then, be hesitant about challenging man with a potential meaning for him to fulfill. It is only thus that we evoke his will to meaning from its state of latency. I consider it a dangerous misconception of mental hygiene to assume that what man needs in the first place is equilibrium or, as it is called in biology, "homeostasis," i.e., a tensionless state. What man actually needs is not a tensionless state but rather the striving and struggling for a worthwhile goal, a freely chosen task. What he needs is not the discharge of tension at any cost but the call of a potential meaning waiting to be fulfilled by him. What man needs is not homeostasis but what I call "noödynamics," i.e., the existential dynamics in a polar field of tension where one pole is represented by a meaning that is to be fulfilled and the other pole by the man who has to fulfill it. And one should not think that this holds true only for normal conditions; in neurotic individuals, it is even more valid. If architects want to strengthen a decrepit arch, they increase the load which is laid upon it, for thereby the parts are joined more firmly together. So if therapists wish to foster their patients' mental health, they should not be afraid to create a sound amount of tension through a reorientation toward the meaning of one's life.
The existential vacuum is a widespread phenomenon of the twentieth century. This is understandable; it may be due to a twofold loss which man has had to undergo since he became a truly human being. At the beginning of human history, man lost some of the basic animal instincts in which an animal's behavior is embedded and by which it is secured. Such security, like Paradise, is closed to man forever; man has to make choices. In addition to this, however, man has suffered another loss in his more recent development inasmuch as the traditions which buttressed his behavior are now rapidly diminishing. No instinct tells him what he has to do, and no tradition tells him what he ought to do; sometimes he does not even know what he wishes to do. Instead, he either wishes to do what other people do (conformism) or he does what other people wish him to do (totalitarianism).
The existential vacuum manifests itself mainly in a state of boredom. [...] there are various masks and guises under which the existential vacuum appears. Sometimes the frustrated will to meaning is vicariously compensated for by a will to power, including the most primitive form of the will to power, the will to money. In other cases, the place of frustrated will to meaning is taken by the will to pleasure. That is why existential frustration often eventuates in sexual compensation. We can observe in such cases that the sexual libido becomes rampant in the existential vacuum.
What matters, therefore, is not the meaning of life in general but rather the specific meaning of a person's life at a given moment. To put the question in general terms would be comparable to the question posed to a chess champion: "Tell me, Master, what is the best move in the world?" There simply is no such thing as the best or even a good move apart from a particular situation in a game and the particular personality of one's opponent. The same holds for human existence. One should not search for an abstract meaning of life. Everyone has his own specific vocation or mission in life to carry out a concrete assignment which demands fulfillment. Therein he cannot be replaced, nor can his life be repeated. Thus, everyone's task is as unique as is his specific opportunity to implement it.
By declaring that man is responsible and must actualize the potential meaning of his life, I wish to stress that the true meaning of life is to be discovered in the world rather than within man or his own psyche, as though it were a closed system. I have termed this constitutive characteristic "the self-transcendence of human existence." It denotes the fact that being human always points, and is directed, to something, or someone, other than oneself - be it a meaning to fulfill or another human being to encounter. The more one forgets himself - by giving himself to a cause to serve or another person to love - the more human he is and the more he actualizes himself. What is called self-actualization is not an attainable aim at all, for the simple reason that the more one would strive for it, the more he would miss it. In other words, self-actualization is possible only as a side-effect of self-transcendence.
[...] there is a danger inherent in the teaching of man's "nothingbutness," the theory that man is nothing but the result of biological, psychological and sociological conditions, or the product of heredity and environment. Such a view of man makes a neurotic believe what he is prone to believe anyway, namely, that he is the pawn and victim of outer influences or inner circumstances. This neurotic fatalism is fostered and strengthened by a psychotherapy which denies that man is free. To be sure, a human being is a finite thing, and his freedom is restricted. It is not freedom from conditions, but it is freedom to take a stand toward the conditions.
Freedom, however, is not the last word. Freedom is only part of the story and half of the truth. Freedom is but the negative aspect of the whole phenomenon whose positive aspect is responsibleness. In fact, freedom is in danger of degenerating into mere arbitrariness unless it is lived in terms of responsibleness.
I speak of a tragic optimism, that is, an optimism in the face of tragedy and in view of the human potential which at its best always allows for: (1) turning suffering into a human achievement and accomplishment; (2) deriving from guilt the opportunity to change oneself for the better; and (3) deriving from life's transitoriness an incentive to take responsible action.
[...] happiness cannot be pursued; it must ensue. One must have a reason to "be happy." Once the reason is found, however, one becomes happy automatically. As we see, a human being is not one in pursuit of happiness but rather in search of a reason to become happy [...] This need for a reason is similar in another specifically human phenomenon - laughter. If you want anyone to laugh you have to provide him with a reason, e.g., you have to tell him a joke. In no way is it possible to evoke real laughter by urging him, or having him urge himself, to laugh.
As to the causation of the feeling of meaninglessness, one may say, albeit in an oversimplifying vein, that people have enough to live by but nothing to live for; they have the means but no meaning. To be sure, some do not even have the means.
The third aspect of the tragic triad concerns death. But it concerns life as well, for at any time each of the moments of which life consists is dying, and that moment will never recur. And yet is not this transitoriness a reminder that challenges us to make the best possible use of each moment of our lives? It certainly is, and hence my imperative: Live as if you were living for the second time and had acted as wrongly the first time as you are about to act now.
In fact, the opportunities to act properly, the potentialities to fulfill a meaning, are affected by the irreversibility of our lives. But also the potentialities alone are so affected. For as soon as we have used an opportunity and have actualized a potential meaning, we have done so once and for all. We have rescued it into the past wherein it has been safely delivered and deposited. In the past, nothing is irretrievably lost, but rather, on the contrary, everything is irrevocably stored and treasured. To be sure, people tend to see only the stubble fields of transitoriness but overlook and forget the full granaries of the past into which they have brought the harvest of their lives: the deeds done, the loves loved, and last but not least, the sufferings they have gone through with courage and dignity.
