Signal-detection methodology may be used to disentangle sensory from judgmental effects when analyzing sex differences in pain. An illustrative example is given by reanalyzing a published category-scaling experiment in terms of detection-theory indices. As a result, the apparent sex difference is recast in terms of a judgmental bias. [berkley].

The article attempts to portray architecture as a spatial medium and to analyse the processing and storage of information, objects and persons. In doing so, architectural space becomes not only the effect of these medial operations, but it also forms and materializes these processes at the same time. Openings are characterized as fundamental elements of architectural media. Also, in this regard, such classic elements as doors and windows in the sense of a room perceived as a perforated membrane, acquire a (...) new medial quality. (shrink)

The paper displays the similarity between the theory of probabilistic causation developed by Glymour et al. since 1983 and mine developed since 1976: the core of both is that causal graphs are Bayesian nets. The similarity extends to the treatment of actions or interventions in the two theories. But there is also a crucial difference. Glymour et al. take causal dependencies as primitive and argue them to behave like Bayesian nets under wide circumstances. By contrast, I argue the behavior of (...) Bayesian nets to be ultimately the defining characteristic of causal dependence. (shrink)

Probability theory, epistemically interpreted, provides an excellent, if not the best available account of inductive reasoning. This is so because there are general and definite rules for the change of subjective probabilities through information or experience; induction and belief change are one and same topic, after all. The most basic of these rules is simply to conditionalize with respect to the information received; and there are similar and more general rules. 1 Hence, a fundamental reason for the epistemological success of (...) probability theory is that there at all exists a well-behaved concept of conditional probability. Still, people have, and have reasons for, various concerns over probability theory. One of these is my starting point: Intuitively, we have the notion of plain belief; we believe propositions2 to be true (or to be false or neither). Probability theory, however, offers no formal counterpart to this notion. Believing A is not the same as having probability 1 for A, because probability 1 is incorrigible3; but plain belief is clearly corrigible. And believing A is not the same as giving A a probability larger than some 1 - c, because believing A and believing B is usually taken to be equivalent to believing A & B.4 Thus, it seems that the formal representation of plain belief has to take a non-probabilistic route. Indeed, representing plain belief seems easy enough: simply represent an epistemic state by the set of all propositions believed true in it or, since I make the common assumption that plain belief is deductively closed, by the conjunction of all propositions believed true in it. But this does not yet provide a theory of induction, i.e. an answer to the question how epistemic states so represented are changed tbrough information or experience. There is a convincing partial answer: if the new information is compatible with the old epistemic state, then the new epistemic state is simply represented by the conjunction of the new information and the old beliefs. This answer is partial because it does not cover the quite common case where the new information is incompatible with the old beliefs. It is, however, important to complete the answer and to cover this case, too; otherwise, we would not represent plain belief as conigible. The crucial problem is that there is no good completion. When epistemic states are represented simply by the conjunction of all propositions believed true in it, the answer cannot be completed; and though there is a lot of fruitful work, no other representation of epistemic states has been proposed, as far as I know, which provides a complete solution to this problem. In this paper, I want to suggest such a solution. In [4], I have more fully argued that this is the only solution, if certain plausible desiderata are to be satisfied. Here, in section 2, I will be content with formally defining and intuitively explaining my proposal. I will compare my proposal with probability theory in section 3. It will turn out that the theory I am proposing is structurally homomorphic to probability theory in important respects and that it is thus equally easily implementable, but moreover computationally simpler. Section 4 contains a very brief comparison with various kinds of logics, in particular conditional logic, with Shackle's functions of potential surprise and related theories, and with the Dempster - Shafer theory of belief functions.

The article deals with some aspects of Dilthey’s thought. First, we examine those elements of Dilthey’s philosophy that play important role in the discussion of his ideas in the 20th century. Next, we refer to the relation of some representatives of late hermeneutics to Dilthey. Finally, we study and evaluate some views of Dilthey’s critics. Key words DILTHEY, HERMENEUTIC PHILOSOPHY.

Der vorliegende Band enthalt sechs teilweise stark iiberarbeitete Aufsatze, die in der Zeit zwischen der Niederschrift des Buches Theorienstrnkturen und Theoriendynamik, Springer-Verlag 1973, im folgenden mit [Theoriendynamik] bezeichnet, und der Monographie The Strncturalist View of Theories. A Pos­ sible Analogue of the Bourbaki Programme in Physical Science, Springer-Ver­ lag 1979, im folgenden kurz [Strnkturalismus] genannt, entstanden sind. In diesen Abhandlungen werden jeweils gewisse Aspekte des strukturalistischen Theorienkonzeptes behandelt. Am starksten iiberarbeitet wurden die Auf­ satze II, IV, V und VI, die (...) urspriinglich in englischer Sprache erschienen waren. Vier der sechs Arbeiten, namlich I, III, IV und VI, bilden auBerdem erweiterte Fassungen von Vortragen. Obwohl das zweite Buch [Strnkturalismus] durch P. Feyerabends ausftihr­ liche Diskussion der strukturalistischen Auffassung im British Journal for the Philosophy of Science, Dezember 1977, angeregt worden ist, stellt es seinem Ansatz und Aufbau nach eher den Versuch einer systematischen Kurzdarstel­ lung des strukturalistischen Vorgehens nach seinem letzten Stande dar. Dem­ gegeniiber entstanden die hier verOffentlichten Artikel stets aus einem ganz be­ stimmten AnlaB. Diese Anlasse konnte man schematisch in drei Klassen unter­ teilen: Entweder ging es darum, eine anschauliche intuitive Ein/iihrnng zu lie­ fern (I und V); oder die Aufgabe bestand darin, die Beziehung zu anderen philosophischen Positionen. wie z. B. derjenigen L. Wittgensteins, H. Putnams, K. Poppers oder T. S. Kuhns. zu analysieren (II. III und IV); oder es sollte zu den wichtigsten und bis dahin verOffentlichten Kritiken Stellung bezogen wer­ den (wie in VI). (shrink)

Let an oracle be called low for prefix-free complexity on a set in case access to the oracle improves the prefix-free complexities of the members of the set at most by an additive constant. Let an oracle be called weakly low for prefix-free complexity on a set in case the oracle is low for prefix-free complexity on an infinite subset of the given set. Furthermore, let an oracle be called low and weakly for prefix-free complexity along a sequence in case (...) the oracle is low and weakly low, respectively, for prefix-free complexity on the set of initial segments of the sequence. Our two main results are the following characterizations. An oracle is low for prefix-free complexity if and only if it is low for prefix-free complexity along some sequences if and only if it is low for prefix-free complexity along all sequences. An oracle is weakly low for prefix-free complexity if and only if it is weakly low for prefix-free complexity along some sequence if and only if it is weakly low for prefix-free complexity along almost all sequences. As a tool for proving these results, we show that prefix-free complexity differs from its expected value with respect to an oracle chosen uniformly at random at most by an additive constant, and that similar results hold for related notions such as a priori probability. Furthermore, we demonstrate that on every infinite set almost all oracles are weakly low but are not low for prefix-free complexity, while by Shoenfield absoluteness there is an infinite set on which uncountably many oracles are low for prefix-free complexity. Finally, we obtain no-gap results, introduce weakly low reducibility, or WLK-reducibility for short, and show that all its degrees except the greatest one are countable. (shrink)

The paper attempts to rationalize cooperation in the one-shot prisoners' dilemma (PD). It starts by introducing (and preliminarily investigating) a new kind of equilibrium (differing from Aumann's correlated equilibria) according to which the players' actions may be correlated (sect. 2). In PD the Pareto-optimal among these equilibria is joint cooperation. Since these equilibria seem to contradict causal preconceptions, the paper continues with a standard analysis of the causal structure of decision situations (sect. 3). The analysis then raises to a reflexive (...) point of view according to which the agent integrates his own present and future decision situations into the causal picture of his situation (sect. 4). This reflexive structure is first applied to the toxin puzzle and then to Newcomb's problem, showing a way to rationalize drinking the toxin and taking only one box with-out assuming causal mystery (sect. 5). The latter result is finally extended to a rationalization of cooperation in PD (sect. 6). (shrink)

We present a reconstruction of so-called classical, formal or Mendelian genetics using a notation which we believe is more legible than that of earlier accounts, and lends itself easily to computer implementation, for instance in PROLOG. By drawing from, and emending, earlier work of Balzer and Dawe (1986,1997), the present account presents the three most important lines of development of classical genetics: the so-called Mendel's laws, linkage genetics and gene mapping, in the form of a theory-net. This shows that the (...) set theoretic representation format used in the structuralist approach to the philosophy of science also applies to the domain of genetic theories. There construction is intended to lend more clarity to theme thodological, philosophical and didactical discussions of the foundations of genetics, and on the other hand to defend a formally, logically minded view of theories which seems to have become contested through the work of Feyerabend, Kuhn and Kitcher.

If it is the tendency of technology, and especially of information and communication technology, particularly in the context of the smart city, not to empower the human person but rather to disenfranchise them by curtailing their capability to judge and choose, how can one counter this dynamic? Code, make, talk, and pray are suggested as possible modes of resistance.

This article tries to disentangle different perspectives on nature in Aristotle's biological work. In one sense Aristotle speaks of nature as a craft-like factor in the generation of living beings. In another sense 'nature' refers to Aristotle's conception of an unchanging universe, in which the individual living beings are perishable, but reproduce themselves and thus guarantee that the essential blueprints of the different species (eidê) remain the same. In addition, however, Aristotle's zoology acknowledges natural processes that involve greater dynamics and (...) more exceptions, most notably when it comes to the allocation of available matter within the animals of a certain species or to the adaptation to a species' proper environment. In conclusion, it seems fair to say that in Aristotle's zoology different autonomous perspectives overlap, so that it would be inappropriate to reduce all of them to a common denominator. (shrink)

In his contribution to this special issue, Almaas is keen to distinguish the individual streams of consciousness from 'pure awareness'. Since the existence of the former is presumably quite uncontroversial in present-day philosophy, I wish to concentrate on the latter, in particular on Almaas's claim that pure awareness is non-individual and ultimately it is 'the true owner of all experiences of all streams'. In my contribution, I wish to make plausible, by a philosophical reflection on the puzzling nature of the (...) I, that the ultimate subject of experience is indeed not the individual but 'the pure ego of the universe'. (shrink)

Philosophers, psychologists, neuroscientists, and psychiatrists examine the will and its pathologies from theoretical and empirical perspectives, offering a conceptual overview and discussing schizophrenia, depression, prefrontal lobe damage, and substance abuse as disorders of volition. Science tries to understand human action from two perspectives, the cognitive and the volitional. The volitional approach, in contrast to the more dominant "outside-in" studies of cognition, looks at actions from the inside out, examining how actions are formed and informed by internal conditions. In Disorders of (...) Volition, scholars from a range of disciplines seek to advance our understanding of the processes supporting voluntary action by addressing conditions in which the will is impaired. Philosophers, psychologists, neuroscientists, and psychiatrists examine the will and its pathologies from both theoretical and empirical perspectives, offering a conceptual overview and discussing specific neurological and psychiatric conditions as disorders of volition. After presenting different conceptual frameworks that identify agency, decision making, and goal pursuit as central components of volition, the book examines how impairments in these and other aspects of volition manifest themselves in schizophrenia, depression, prefrontal lobe damage, and substance abuse.

The existence of a Catholic Intellectual Tradition (CIT) is not a given, as arguments contra are in balance with arguments pro. An intellectual tradition consists of a style of thought and of a worldview, as its formal and material modes. The former defines the way knowledge is appropriated, processed, and passed on whereas the latter amounts to its applications to various regions of reality – God, man, morality, society, the Church, etc. A model of the CIT is proposed that consists (...) of principles differentiated by the degree of centrality they have in a topological structure. The paper asserts the existence of a CIT because a non-stipulative, non-trivial, and non-circular case can be made for it. (shrink)

Wolfgang Köhler (1887-1967) was one of the founders of Gestalt psychology, the influential school that argues that perception is best understood as an organized pattern rather than as separate parts. Penetrating in its insights and lucid in presentation, Gestalt Psychology (1947) is Köhler's definitive statement of Gestalt theory.
