Die vorliegende Arbeit untersucht Möglichkeiten und Grenzen der Verwendung von einfachen konnektionistischen Systemen als Modelle für den Erwerb und die Repräsentation von Wissen über zeitdiskrete lineare dynamische Systeme in der Kognitionspsychologie. Ein ausgewähltes dynamisches System namens SINUS wird in Form eines „pattern associators“ repräsentiert und dessen Lernverhalten untersucht. Es wird versucht, daraus Annahmen über den Wissenserwerb von Probanden im Umgang mit solchen dynamischen Systemen abzuleiten, um insbesondere Hinweise darauf zu erhalten, was „gute“ von „schlechten“ Probanden unterscheidet. Ein weiterer hier betrachteter (...) Aspekt ist die Steuerung eines dynamischen Systems in einen vorgegebenen Zielzustand, der unter Beibehaltung des konnektionistischen Modells durch einen variierten Lernalgorithmus modelliert wird. Die abschließende Diskussion geht auf die Bedeutung der Modellierung für die kognitionspsychologische Theorienbildung ein. (shrink)

Review of Nils Hoppe book, Bioequity--Property in the Body.

We defend a view according to which Austrian economics rests on what can most properly be called an Aristotelian methodology. This implies a realist perspective, according to which the world exists independently of our thinking and reasoning activities; an essentialist perspective, according to which the world contains certain simple essences or natures which may come together in law-like ways to form more complex static and dynamic wholes, and an apriorist perspective, according to which given essences and essential structures are intelligible, (...) in the sense that they ca be grasped non-inductively in our thinking. We show the consequences of this view for an analysis of the thinking of Mises and Hoppe, both of which – we claim – incorporate what we believe to be foreign mixtures of Kantianism in their account of the foundations of Austrian economics.

A critical but underdeveloped part of the libertarian debate about immigration is the question of who, if anyone, owns public property, and the consequences of the answer to this question. Libertarians who favor restrictive immigration policies, such as Hans-Hermann Hoppe, argue that taxpayers own public property, and that the state, while it is in control of such property, should manage it on behalf of taxpayers in the same way private owners would manage their own property. In other words, it (...) should be quite selective about who may enter. Walter Block, who takes an “open borders” position, does not appear to dispute the claim that taxpayers own public property, but nevertheless argues that immigrants are entitled to ignore the state’s control of, and thus may freely enter, such property. In this article I explore the question of public property ownership using Rothbardian property rights principles. I conclude that, at least with respect to a particular type of public property, neither Hoppe’s nor Block’s reasoning is consistent with these principles. I also consider the idea that the state ought to have a role in managing public property in light of some libertarian anarchist ideas about the state. I conclude that supporting a legitimate role for the state as an immigration gatekeeper is inconsistent with Rothbardian and Hoppean libertarian anarchism, as well as with the associated strategy of advocating always and in every instance reductions in the state’s role in society.

A recent trend in Husserl scholarship takes the Logische Untersuchungen (LU) as advancing an inconsistent and confused view of the non-conceptual content of perceptual experience. Against this, I argue that there is no inconsistency about non-conceptualism in LU. Rather, LU presents a hybrid view of the conceptual nature of perceptual experience, which can easily be misread as inconsistent, since it combines a conceptualist view of perceptual content (or matter) with a non-conceptualist view of perceptual acts. I show how this hybrid (...) view is operative in Husserl’s analyses of essentially occasional expressions and categorial intuition. And I argue that it can also be deployed in relation to Husserl’s analysis of the constitution of perceptual fullness, which allows it to avoid a objection raised by Walter Hopp—that the combination of Husserl’s analysis of perceptual fullness with conceptualism about perceptual content generates a vicious regress.
