“If we would stand up and be counted on the side of reason, we ought to drop terms like 'pseudoscience' and 'unscientific' from our vocabulary; they are just hollow phrases which do only emotive work for us.”

Larry Laudan (1941) American philosopher

"The Demise of the Demarcation Problem", in Cohen, R.S.; Laudan, L., Physics, Philosophy and Psychoanalysis: Essays in Honor of Adolf Grünbaum (1983)

“Of the three great skeptics I interviewed, Popper was the first to make his mark. His philosophy stemmed from his effort to distinguish pseudoscience, such as Marxism or astrology or Freudian psychology, from genuine science, such as Einstein's theory of relativity. The latter, Popper decided, was testable; it made predictions about the world that could be empirically checked. The logical positivists had said as much. But Popper denied the positivist assertion that scientists can prove a theory through induction, or repeated empirical tests or observations. One never knows if one's observations have been sufficient; the next observation might contradict all that preceded it. Observations can never prove a theory but can only disprove, or falsify it. Popper often bragged that he had "killed" logical positivism with this argument.”

“Convicted fraud and pseudoscience charlatan, Mister Kent Hovind argues that what has already been directly-observed and shown to be certainly true is (in his opinion) impossible, and the only option he thinks is possible is that an imperceptible (and possibly imaginary) mystical being poofed everything out of nothing by magic. The irony is that what he proposes is physically impossible because it defies all natural laws, and it’s logically implausible since it has neither precedent nor parallel anywhere in reality to imply that it could still be true anyway. Where is there evidence anywhere that such a thing actually exists, or that anything even could have any of these abilities?”

“Enormous resources are invested in pseudoscience that could be better invested in improving the health and education of the public.”

“After we have become familiar with the new idea, however, after it has become part of our general stock of theoretical concepts, our expectations are brought more into balance with its actual uses, and its excessive popularity is ended. A few zealots persist in the old key-to-the-universe view of it; but less driven thinkers settle down after a while to the problems the idea has really generated. They try to apply it and extend it where it applies and where it is capable of extension; and they desist where it does not apply or cannot be extended. It becomes, if it was, in truth, a seminal idea in the first place, a permanent and enduring part of our intellectual armory. But it no longer has the grandiose, all-promising scope, the infinite versatility of apparent application, it once had. The second law of thermodynamics, or the principle of natural selection, or the notion of unconscious motivation, or the organization of the means of production does not explain everything, not even everything human, but it still explains something; and our attention shifts to isolating just what that something is, to disentangling ourselves from a lot of pseudoscience to which, in the first flush of its celebrity, it has also given rise.”

“If the Moon is made of green cheese, then Napoleon lost the battle of Waterloo.
We would be committing this fallacy (i. e., affirming the consequent) if we used this sentence to claim that the Moon is made of green cheese. Pseudosciences employ this fallacy frequently, because it enables you to claim the truth of any premise you wish simply by choosing a true conclusion.”

Truth

“We tend to think of [Hitler] as an idiot because the central tenet of his ideology was idiotic – and idiotic, of course, it transparently is. Anti-Semitism is a world view through a pinhole: as scientists say about a bad theory, it is not even wrong. Nietzsche tried to tell Wagner that it was beneath contempt. Sartre was right for once when he said that through anti-Semitism any halfwit could become a member of an elite. But, as the case of Wagner proves, a man can have this poisonous bee in his bonnet and still be a creative genius. Hitler was a destructive genius, whose evil gifts not only beggar description but invite denial, because we find it more comfortable to believe that their consequences were produced by historical forces than to believe that he was a historical force. Or perhaps we just lack the vocabulary. Not many of us, in a secular age, are willing to concede that, in the form of Hitler, Satan visited the Earth, recruited an army of sinners, and fought and won a battle against God. We would rather talk the language of pseudoscience, which at least seems to bring such events to order. But all such language can do is shift the focus of attention down to the broad mass of the German people, which is what Goldhagen has done, in a way that, at least in part, lets Hitler off the hook – and unintentionally reinforces his central belief that it was the destiny of the Jewish race to be expelled from the Volk as an inimical presence.”

“Man is a moral creature. The moral sense is so deeply rooted in human beings that no thief, no murderer has ever asked the abrogation of the penalties against theft and murder. All the laws that have ruled human organization in the past and rule them at present are based on the moral sense: on what is right and wrong. And no religion, no legislature has ever deemed it necessary to define right and wrong, because no one has any doubt as to the meaning of these terms. Only the worshippers of the pseudoscience of modern times regard morality and immorality, justice and injustice, good and evil, as anti-scientific concepts, since it is not possible to reproduce them in a laboratory. … The reasonings of the vivisectionists are unscientific because they don't take into account the intangible realities of life. The moral law is one such intangible reality: And it is the incomprehension of this reality that marks the inescapable failure of experimental science when applied to living beings, with its inevitable sequence of tragic errors.”

“[In] economics… you can disguise charlatanism under the weight of equations and nobody can catch you since there is no such thing as a controlled experiment. Now the spirit of such methods, called scientism by its detractors, continued into the discipline of finance as a few technicians thought their mathematical knowledge could lead them to understand markets. The practice of financial engineering came along with massive doses of pseudoscience.”

“There are still some things we haven’t quite worked out, but we know enough to be sure we’re on the right track. However apparently, our teachers are supposed to tell students that whenever we haven’t figured something out yet, we should stop our research and assume God did it—as if magic counts as an explanation. If we don’t yet know exactly how the first living cells formed, that somehow negates everything we do know to be true about evolution after that. But worse, creationists want to mislead our kids into thinking that every kind of life appeared all at once, ignoring all the evident stages of progression stretched across time, and all the apparent predecessors found in earlier strata. They want to teach as fact outright falsehoods easily disproved, as well as pseudoscience already publicly exposed in a court of law.”

“Inspect every piece of pseudoscience and you will find a security blanket, a thumb to suck, a skirt to hold. What does the scientist have to offer in exchange? Uncertainty! Insecurity!”

“Popper’s attempt to construct a methodology from falsification may have been flawed, but the concept is central in the demarcation of science from nonscience. No matter how strong one’s convictions, a true scientist will always allow for the possibility that her results may be falsified; if she denies this possibility or refuses to abandon or modify a theory in the face of repeated falsifications, you can be sure that you are dealing with pseudoscience, not science.”

“Through use and abuse of hidden postulates, of bold, often ill-founded extrapolations, a pseudoscience has been created. It is taking root in the very heart of biology and is leading astray many biochemists and biologists, who sincerely believe that the accuracy of fundamental concepts has been demonstrated, which is not the case.”

Pierre-Paul Grassé (1895–1985) French zoologist

Grassé, Pierre Paul (1977); Evolution of living organisms: evidence for a new theory of transformation. Academic Press, p. 6
Evolution of living organisms: evidence for a new theory of transformation (1977)
Context: Through use and abuse of hidden postulates, of bold, often ill-founded extrapolations, a pseudoscience has been created. It is taking root in the very heart of biology and is leading astray many biochemists and biologists, who sincerely believe that the accuracy of fundamental concepts has been demonstrated, which is not the case. Wishing to point out this type of misconception, we quote P. T. Mora, an American biochemist, who writes about polysaccharides contained in the cell membrane: To admit that the action of enzymes and, enzymes and, more important, that their foundation is directed by the genetic code should not permit one to mantain that the information was selected by evolution (the consequence is mistaken for the cause); no one knows anything about this.

“Economics was like psychology, a pseudoscience trying to hide that fact with intense theoretical hyperelaboration. And gross domestic product was one of those unfortunate measurement concepts, like inches or the British thermal unit, that ought to have been retired long before.”
