This paper presents an outline of a new theory of relevant deduction which arose from the purpose of solving paradoxes in various fields of analytic philosophy. In distinction to relevance logics, this approach does not replace classical logic by a new one, but distinguishes between relevance and validity. It is argued that irrelevant arguments are, although formally valid, nonsensical and even harmful in practical applications. The basic idea is this: a valid deduction is relevant iff no subformula of the conclusion (...) is replaceable on some of its occurrences by any other formula salva validitate of the deduction. The paper first motivates the approach by showing that four paradoxes seemingly very distant from each other have a common source. Then the exact definition of relevant deduction is given and its logical properties are investigated. An extension to relevance of premises is discussed. Finally the paper presents an overview of its applications in philosophy of science, ethics, cognitive psychology and artificial intelligence. (shrink)

The basic theory of scientific understanding presented in Sections 1–2 exploits three main ideas.First, that to understand a phenomenonP (for a given agent) is to be able to fitP into the cognitive background corpusC (of the agent).Second, that to fitP intoC is to connectP with parts ofC (via arguments in a very broad sense) such that the unification ofC increases.Third, that the cognitive changes involved in unification can be treated as sequences of shifts of phenomena inC. How the theory fits (...) typical examples of understanding and how it excludes spurious unifications is explained in detail. Section 3 gives a formal description of the structure of cognitive corpuses which contain descriptive as well as inferential components. The theory of unification is then refined in the light of so called puzzling phenomena, to enable important distinctions, such as that between consonant and dissonant understanding. In Section 4, the refined theory is applied to several examples, among them a case study of the development of the atomic model. The final part contains a classification of kinds of understanding and a discussion of the relation between understanding and explanation. (shrink)

Function and teleology can be naturalized either by reference to systems with a particular type of organization or by reference to a particular kind of history. As functions are generally ascribed to states or traits according to their current role and regardless of their origin, etiological accounts are inappropriate. Here, I offer a systems-theoretical interpretation as a new version of an organizational account of functionality, which is more comprehensive than traditional cybernetic views and provides explicit criteria for empirically testable function (...) ascriptions. I propose, that functional states, traits or items are those components of a complex system, which are under certain circumstances necessary for their self-re-production. I show, how this notion can be applied in intra- and trans-generational function ascriptions in biology, how it can deal with the problems of multifunctionality and functional equivalents, and how it relates to concepts like fitness and adaptation. Finally, I argue that most intentional explanations can be treated as functional explanations. (shrink)

This paper supplements an earlier one (Wassermann 1978b). Its views aim to reinforce those of Lewontin and other prominent evolutionists, but differ significantly from the opinions of some philosophers of science, notably Popper (1957) and Olding (1978). A basic distinction is made between 'laws' and 'theories of mechanisms'. The 'Theory of Evolution' is not characterized by laws, but is viewed here as a hypertheory which explains classifiable evolutionary phenomena in terms of subordinate classifiable theories of 'evolution-specific mechanisms' (ESMs), each of (...) which could apply to a host of species. Adaptations could result from ESMs that are rooted in molecular complementarities. The status of optimization theories that aim to predict best adapted states of organisms or populations is also discussed. (shrink)

, Pietroski and Rey ([1995]) suggested a reconstruction of ceteris paribus (CP)-laws, which — as they claim — saves CP-laws from vacuity. This discussion note is intended to show that, although Pietroski and Rey's reconstruction is an improvement in comparison to previous suggestions, it cannot avoid the result that CP-laws are almost vacuous. It is proved that if Cx is an arbitrary (nomological) event-type which has independently identifiable deterministic causes, then for every other (nomological) event-type Ax which is not strictly (...) connected with Cx or with ¬Cx, ‘CP if Ax then Cx’ satisfies the conditions of Pietroski and Rey for CP-laws. It is also shown that Pietroski and Rey's reconstruction presupposes the assumption of determinism. The conclusion points towards some alternatives to Piectroski and Rey's reconstruction. (shrink)

In this article I argue that contractarian theory is a fruitful approach for dealing with questions of legitimacy in light of globalisation. I try to point out that impaired conditions for providing collective goods in nation-states do not call the legitimacy of globalisation into question, even if the provision of such goods meets with consent amongst the citizens of the nation-state. The need to raise taxes as a consequence of the transfer of mobile resources to other countries can indicate the (...) existence of state activities which lack legitimacy from the contractarian perspective. However, the impossibility of applying the exclusion principle in providing collective goods indeed entails legitimatory problems of globalisation. In this respect, a need for international agreements exists. Nevertheless, unilateral attempts by nation-states to withraw the domestic economy from global influences can interfere with the welfare of other collectives and they therefore lack legitimacy, a moral consequence which is in danger of being neglected even from a contractarian approach.

The Diagnostic Understanding of Gestalt Theoretical Psychotherapy: In accordance with the basic thoughts of the Guideline, Gestalt Theoretical Psychotherapy acts on the conviction that diagnostic revelations and therapeutic change processes are inseparable. Even if each of them is related to different functions and thus to particular demands, an efficient patient support requires the professional and proper interplay of discovery and change processes throughout her therapy. Each new discovery is per se related to a change and may set off a series (...) of further changes, which may again trigger off new discoveries. As widely known, this may also happen when this whole process and this cause-and-effect-relation are neither intended, nor planned, nor insightfully administered or understood. The authors of the Guideline are, therefore, right to not only ascertain the fact that discovering and changing in psychotherapy are joint and intertwining processes, but also to postulate that the psychotherapist has to work on this intertwining process consciously and deliberately, guided by and in accordance with her particular scientific-methodological approach. Even in the diagnostic strand of psychotherapeutic work, Gestalt Theoretical psychotherapists let themselves be guided by the “characteristics of working at the living”, as they were elaborated by Wolfgang Metzger (1962) and transferred to psychotherapeutic applications by Hans-Jürgen P. Walter (1977) and his colleagues. Simultaneously, essential anthropological, epistemological and ethical home positions of Gestalt theory are concisely expressed therein. I am going to mention them briefly, reformulating them in reference to the diagnostic remit. By doing so, the accordance with the major viewpoints of the Guideline in the description of diagnostic processes in psychotherapy should become apparent. (shrink)

In light of the phenomenon of the “coexistence of the non-contemporaneous” [Gleichzeitigkeit des Ungleichzeitigen] every periodic division is problematic, for usually the old exists simultaneously with the new, that which looks to the past exists beside that which points to the future. This is also true for the beginning of “modern times”: Beside the first modern attempts to define the fundamentals of moral conduct without recourse to metaphysical assumptions, the “old dictates” remained in effect for whose truth divine revelation was (...) claimed. Some theoreticians of modernity held a conciliatory position in which they clung to God’s existence, but they no longer looked to infer His attributes from the Book of Books but, rather, out of creation — from the book of nature. Nevertheless the project of the Enlightenment, to find a secular foundation for morality, was worked on more and more self-consciously, and the greatest radicals even went a step further: They held the traditional form of religion, under which in the following is always meant: the Christian-theistic form of religion, to be morally threatening. David Hume was one of them. His provocative reflections on this subject are the object of the following comments. (shrink)

The paper critically reconstructs the crowd psychological heritage in phenomenological and social science emotion research. It shows how the founding figures of phenomenology and sociology uncritically adopted Le Bon’s crowd psychological imagery as well as what I suggest calling the disease model of emotion transfer. Against this background, it can be examined how Le Bon’s understanding of emotional contagion as an automatic, involuntary, and uncontrollable mechanism has remained a dominant force in emotion research until today. However, a closer look at (...) phenomenological descriptions and empirical investigations of how emotion’s spread shows that there is little evidence supporting Le Bon’s crowd psychological framework. Thus, I suggest that the disease model should be dismissed in favor of more plausible approaches to interpersonal emotion dynamics. (shrink)
