In this paper I will argue that a profile of the pseudo-sciences can be gained from the scientific pretensions of the pseudo-scientist. These pretensions provide two yardsticks which together take care of the charge of scientific prejudice that any suggested demarcation of pseudo-science has to face. To demonstrate that my analysis has teeth I will apply it to Freud and modern-day Bach-kabbalists. Against Laudan I will argue that the problem of demarcation is not a pseudo-problem, though the discussion will bear (...) out that Laudan's replacement question, namely the question whether someone's theory is well-confirmed, is not, as Lugg claimed, independent of the question as to whether that person is a pseudo-scientist. I further argue that my prototype pseudo-scientists do not have the shortcomings highlighted in Thagard's recent analysis of pseudo-science. (shrink)

In his The Foundations of Psychoanalysis (1984) Grunbaum compliments Freud on the development of the Tally Argument as an answer to a number of serious methodological criticisms, "The epistemological considerations that prompted Freud to enunciate (this argument) make him a sophisticated methodologist" (p. 128). In contrast to this position I argue that the Tally Argument and the considerations for it are hardly sophisticated: They would equally well go to demonstrate the methodological sophistication of modern-day evangelists. Furthermore, I argue that the (...) Tally Argument does not play the crucial role that Grunbaum assigns to it. It is one of many arguments Freud used to counter criticism, but not one to which Freud gave pride of place. (shrink)

In this note I test a specific thesis about the dependence of philosophy of science on science that Laudan presents in his Science and Hypothesis; namely, that the sciences were justificationally prior to the philosophy of science. I argue that Laudan's historical case studies show a justificational priority that goes the other way. I also argue that the justificational role that in Progress and Its Problems the history of science is alleged to play vis-à-vis competing conceptions of scientific rationality is (...) not apparent in Laudan's argumentation in favor of his suggested analysis in terms of problem-solving effectiveness.

Dennett's "Consciousness Explained" (1991) is an inspiring but also a highly frustrating book. The line of the argument seems to be clear, but then at second sight it fades away. It turns out that Dennett uses six of the seven strategies which I discuss in my 'The Seven Strategies of the Sophisticated Pseudo-Scientist: A Look into Freud's Rhetorical Tool Box' (J. Gen. Phil. Sci., 2001) Discussing important examples of these strategies I show why "Consciousness Explained" is such a frustrating book. (...) As the examples used do not reflect minor problems but go to the heart of the matter and concern the book's main areas of contention, it turns out that, in spite of the valuable and insightful details, Dennett's materialistic view of consciousness is supported mainly by rhetorical sleights of hand.

John Hyman has used the objective character of occlusion shapes and of relative occlusion sizes to develop a more objective approach both in the analysis of linear perspective and in the theory of depiction. To this end Hyman develops two Occlusion Principles, plus an Aperture Colour Principle (which I do not discuss), which, together with our knowledge of appearances, are supposed to tell us what a picture depicts. I argue that Hyman underestimates the crucial role of the psychological element in (...) the work that the objective occlusion shape and relative occlusion sizes are assigned to do. Two pictures may have different contents in spite of the same occlusion shapes and the same (relative) occlusion sizes. It is the operation of constancy scaling in pictorial space which frustrates Hyman’s objectivism both in the domain of linear perspective and in the domain of depiction. (shrink)
