In both cases, it may indeed be necessary to engage in empirical analysis to determine what is being claimed. A pseudoscientific theory, like a fallacious argument, may be obscurely presented and even when clearly presented it may misrepresent what its proponents intend. Beyond this, however, empirical analysis is neither required nor appropriate. We no more need to know anything about the world to say that theories are pseudoscientific than we need to know anything about it to say that arguments are invalid. Judgements about scientificity, like judgements of validity, have nothing to do with empirical well-foundedness and truth. Ondráček ·ZAFI ·2021 10 / 61 CO? pseudo-věda Derksen: The Seven Sins (Derksen, 1993, 2001) • Dearth of Decent Evidence • pretense to producing reliable knowledge, obtained via trustworthy methods • Unfounded Immunizations • accepting only particular interpretations of the data • Ur-Temptations • uncritically assigning a deeper significance to prima facie spectacular coincidences • Magic Methods • Insights of Innatates • Only the initiate has the right perspective on the truth. • All-Explaining Theories • Uncritical and Excessive Pretensions Ondráček ·ZAFI ·2021 11 / 61 CO? pseudo-věda Minimum of the Demarcation (Ondráček, 2020) Any scientific discussion has to aspire to critical discussion and has to be done in a scientific context (has to be labeled by protagonists as scientific). Ondráček ·ZAFI ·2021 12 / 61 CO? imunizace Popper: Conventionalism (Popper, 2005b: 15); (Popper, 2005a: 58, 61) I very soon found that every theory can be “immunized” (this excellent term is due to Hans Albert) against criticism. If we allow such immunization, then every theory becomes unfalsifiable. Thus we must exclude at least some immunizations. Only the ‘laws of nature’ are simple; and these, the conventionalist holds, are our own free creations; our inventions; our arbitrary decisions and conventions. The only way to avoid conventionalism is by taking a decision: the decision not to apply its methods. Ondráček ·ZAFI ·2021 13 / 61 CO? imunizace Immunizing Strategies and Epistemic Defense Mechanisms Boudry and Braeckman (2011: 146) We define an ‘immunizing strategy’ as an argument brought forward in support of a belief system, though independent from that belief system, which makes it more or less invulnerable to rational argumentation and/or empirical evidence. By contrast, an epistemic ‘defense mechanism’ is defined as an internal structural feature of a belief system, which has the same effect of deflecting rational arguments and empirical refutations. Ondráček ·ZAFI ·2021 14 / 61 CO? imunizace Popper: Types of Immunizations (Popper, 2005a: 62) Types introduction of ad hoc hypotheses modification of ostensive (or explicit) definition adoption of sceptical attitude as to the reliability of the experimenter justifications or the experimenter herself cast doubts on the acumen of the theoretician Ondráček ·ZAFI ·2021 15 / 61 CO? imunizace Popper: Types of Immunizations (Popper, 2005a: 62) The list makes no claim to completeness: it must be left to the investigator, especially in the fields of sociology and psychology (the physicist may hardly need the warning) to guard constantly against the temptation to employ new conventionalist stratagems–a temptation to which psychoanalysts, for example, often succumb.

An irreducibly complex system cannot be produced directly (that is, by continuously improving the initial function, which continues to work by the same mechanism) by slight, successive modifications of a precursor system, because any precursor to an irreducibly complex system that is missing a part is by definition nonfunctional.

I am going to refer to this position as the No-Position Position. Secondly, alogosia is asserted: true normative theories of objective rationality are not available; whatever we take to be the canons of rationality are constructions, so could have been constructed differently, and although there may be some ways in which they could not be constructed, among those ways in which they can be constructed there are no better or worse ways of constructing them.“ • P-D 2 Obligation to Defend Rule • Discussants who advance a standpoint may not refuse to defend this standpoint when requested to do so.

And lest, from some cause or other, individuals of the latter classes should resist the magnetic charm, the apostles of the science declare that there are times when even they cannot be acted upon; the presence of one scorner or unbeliever may weaken the potency of the fluid and destroy its efficacy.

Ondráček ·ZAFI ·2021 50 / 61 DOPLNĚNÍ Kuhn and Lakatos: criticism (Lakatos, 1978: 5–4) Scientists have thick skins. They do not abandon a theory merely because facts contradict it. They normally either invent some rescue hypothesis to explain what they then call a mere anomaly or, if they cannot explain the anomaly, they ignore it, and direct their attention to other problems. Note that scientists talk about anomalies, recalcitrant instances, not refutations. Ondráček ·ZAFI ·2021 51 / 61 DOPLNĚNÍ Popper: Revaluation (Popper, 2005b: 43) On the other hand, I also realized that we must not exclude all immunizations, not even all which introduced ad hoc auxiliary hypotheses. For example the observed motion of Uranus might have been regarded as a falsification of Newton’s theory. Instead the auxiliary hypothesis of an outer planet was introduced ad hoc, thus immunizing the theory. This turned out to be fortunate; for the auxiliary hypothesis was a testable one, even if difficult to test, and it stood up to tests successfully. All this shows not only that some degree of dogmatism is fruitful, even in science, but also that logically speaking falsifiability, or testability, cannot be regarded as a very sharp criterion. Ondráček ·ZAFI ·2021 52 / 61 DOPLNĚNÍ Popper: admissibility of immunizations • empirical content • new theory • reasonableness • ... Ondráček ·ZAFI ·2021 53 / 61 DOPLNĚNÍ Derksen: reprehensibility of immunizations (Derksen, 1993: 24) Yet, immunizing is not always reprehensible. In fact, as far as the argumentation is concerned there is nothing wrong with immunization. Immunization is nothing but arguing on the assumed truth of one’s theory. There is nothing against this, as long as the theory is well-confirmed. Immunization becomes reprehensible only when it is unfounded. Ondráček ·ZAFI ·2021 54 / 61 CONCLUSION & OVERVIEW science as a tool (Sagan, 2006) My deeply held belief is that if a god of anything like the traditional sort exists, then our curiosity and intelligence are provided by such a god. We would be unappreciative of those gifts if we suppressed our passion to explore the universe and ourselves. On the other hand, if such a traditional god does not exist, then our curiosity and our intelligence are the essential tools for managing our survival in an extremely dangerous time. In either case the enterprise of knowledge is consistent surely with science; it should be with religion, and it is essential for the welfare of the human species.
