This is an attempt to interpret the history of mechanism vs. vitalism in relation to the changing framework of culture and to show the interrelation between both these views and experimental science. After the scientific revolution of the seventeenth century, causal mechanism of classical physics provided the framework for the study of nature. The teleological and holistic properties of life, however, which are incompatible with this theory yielded — as a result both of internal developments within biology and of a (...) general reaction against dogmatic rationalism — to a vitalistic interpretation of life which ascribed a mysterious force to living organisms. It will be shown that both mechanism and vitalism are related to the experimental climate of the time in which they were popular. The controversy has now lost its raison d'être as a result of the development of the theory of systems and of a better understanding of the chemistry and evolution of life. (shrink)

The aim of the present volume is to draw the balance of naturalism's success so far.

The viewpoint of Evolutionary Epistemology (EE) and of Genetic Epistemology (GE) on classical epistemological questions is strikingly different: EE starts with Evolutionary Biology, the subject of which is population's dynamics. GE, however, starts with Developmental Psychology and thus focusses the development of individuals. By EE knowledge is seen as portraying or copying process, and truth is interpreted as a product of adaptation, whereas for GE knowledge is due to a construction process in which the production of true insights is only (...) one possibility among others: Like falsity, error and deception, true knowledge goes back to a free relationship to reality. The difference between scientific and common knowledge is hard to be checked by EE, since both result ultimately from human hereditary structures. The study of how scientific knowledge emerges from everyday cognition is rather the task of GE. (shrink)

Summary In the first part of this contribution, the three probably most influential conceptions of evolutionary epistemology are surveyed, as they were put forward by Konrad Lorenz, Gerhard Vollmer, and Rupert Riedl, respectively. It is demonstrated that, as far as the essentials are concerned, these conceptions largely correspond with each other as well as with a further conception advanced by Karl Popper from the point of view of Critical Rationalism. It can be clearly shown, moreover, that fundamentals of the latter (...) conception can be traced back to Popper's earliest publications (e. g., to hisLogik der Forschung [The Logic of Scientific Discovery]). By means of an examination of the language used by these authors, it is tried to elucidate the fact that, for the reasons of lacking consideration of the lingual/non-lingual distinction and of faults and inadequacies in consequence of this lack alone, the proposed conceptions can be rejected as being at least highly defective.

It is shown that the method of operationaldefinition of theoretical terms applied inphysics may well support constructivist ideasin cognitive sciences when extended toobservational terms. This leads to unexpectedresults for the notion of reality, inductionand for the problem why mathematics is sosuccessful in physics.A theory of cognitive operators is proposedwhich are implemented somewhere in our brainand which transform certain states of oursensory apparatus into what we call perceptionsin the same sense as measurement devicestransform the interaction with the object intomeasurement results. Then, (...) perceivedregularities, as well as the laws of nature wewould derive from them can be seen asinvariants of the cognitive operators concernedand are by this human specific constructsrather than ontologically independent elements.. So, reality in so far it isrepresented by the laws of nature has no longeran independent ontological status. This isopposed to Campbell's `natural selectionepistemology'. From this it is shown that thereholds an incompleteness theorem for physicallaws similar to Gödels incompletenesstheorem for mathematical axioms, i.e., there isno definitive or object `theory of everything'.This constructivist approaches to cognitionwill allow a coherent and consistent model ofboth cognitive and organic evolution. Whereasthe classical view sees the two evolutionrather dichotomously. (shrink)

Scientific knowledge should not only be true, it should be as objective as possible. It should refer to a reality independent of any subject. What can we use as a criterion of objectivity? Intersubjectivity (i.e., intersubjective understandability and intersubjective testability) is necessary, but not sufficient. Other criteria are: independence of reference system, independence of method, non-conventionality. Is there some common trait? Yes, there is: invariance under some specified transformations. Thus, we say: A proposition is objective only if its truth is (...) invariant against a change in the conditions under which it was formulated. We give illustrations from geometry, perception, neurobiology, relativity theory, and quantum theory. Such an objectivist position has many advantages. (shrink)

The author takes the interdisciplinary seminar on Evolutionary Epistemology at the 7th International Wittgenstein Symposium as the occasion to discuss the question of the status, achievements and limits of Evolutionary Epistemology. She comes to the conclusion that neither its critique of the quid juris question in traditional epistemology nor its own philosophical pretensions can be justified. But it is a new science which is relevant and a challenge to traditional epistemology and philosophy of science in that it opens up a (...) horizon of new questions which they will have to take seriously.

The modern conception of enactive cognition is under discussion from the standpoint concerning the notions of nonlinear dynamics and synergetics. The contribution of Francisco Varela and his precursors is considered. It is shown that the perceptual and mental processes are bound up with the “architecture” of human body and nonlinear and circular connecting links between the subject of cognition and the world constructed by him can be metaphorically called a nonlinear cobweb of cognition. Cognition is an autopoietic activity because it (...) is directed to the search of elements that are missed; it serves to completing integral structures. (shrink)

The primary outcome of natural selection is adaptation to an environment. The primary concern of epistemology is the acquistion of knowledge. Evolutionary epistemology must therefore draw a fundamental connection between adaptation and knowledge. Existing frameworks in evolutionary epistemology do this in two ways; (a) by treating adaptation as a form of knowledge, and (b) by treating the ability to acquire knowledge as a biologically evolved adaptation. I criticize both frameworks for failing to appreciate that mental representations can motivate behaviors that (...) are adaptive in the real world without themselves directly corresponding to the real world. I suggest a third framework in which mental representations are to reality as species are to ecosystems. This is a many-to-one relationship that predicts a diversity of adaptive representations in the minds of interacting people. As “species of thought”, mental representations share a number of properties with biological species, including isolating mechanisms that prevent them from blending with other representations. Species of thought also are amenable to the empirical methods that evolutionists use to study adaptation in biological species. Empirical studies of mental representations in everyday life might even be necessary for science to succeed as a normative “truth-seeking” discipline. (shrink)

Summary Prägnanz was suggested by Max Wertheimer in the 1920s as subsuming all “Laws of Gestalt” as they apply to visual awareness. Thus, it assumes a prominent position in any account of Gestalt phenomena. From a phenomenological perspective, some visual stimuli evidently “have more Prägnanz” than others, so Prägnanz seems to be an intensive quality. Here, we investigate the intricacies that need to be faced on the way to a definition of formal scales. Such measures naturally depend both upon the (...) stimulus and upon the observer. Structural complexity bottlenecks of visual systems play a role, as well as the relevance to biological fitness, that is the affinity to the optical user interface. This positions the notion of Prägnanz squarely within the realm of biology. Indeed, the familiar “releasers” of ethology are singular cases of extremely high Prägnanz. (shrink)

Aside from his remarkable studies in psychology and the social sciences, Donald Thomas Campbell (1916–1996) made significant contributions to philosophy, particularly philosophy of science,epistemology, and ethics. His name and his work are inseparably linked with the evolutionary approach to explaining human knowledge (evolutionary epistemology). He was an indefatigable supporter of the naturalistic turn in philosophy and has strongly influenced the discussion of moral issues (evolutionary ethics). The aim of this paper is to briefly characterize Campbells work and to discuss its (...) philosophical implications. In particular, I show its relevance to some current debates in the intersection of biology and philosophy. In fact, philosophy of biology would look poorer without Campbells influence. The present paper is not a hagiography but an attempt to evaluate and critically discuss the meaning of Campbells work for philosophy of biology and to encourage scholars working in this field to read and re-read this work which is both challenging and inspiring.

Self-Reference and Correspondence. How Constructive is Our Knowledge? Basing on scientific results Radical Constructivism and Evolutionary Epistemology claim to be able to answer the question concerning the epistemological status of our knowledge - but they arrive at opposite conditions regarding the constructive or realistic character of our worldview. A critical discussion of these two positions reveals that they don't satisfy their own demands. The limits of an exclusively scientifically based epistemology are getting obvious when we bring up the genetic epistemology (...) of Jean Piaget who ties the knowledge of the world down to acting in the world, which brings the actor back into epistemology and transcends the realm of science. This discloses at the same time the insufficiency of a bipolar questioning that turns constructivism and realism into an unsuperable antogonism. In a concluding reflection the necessity of a sociological enlargement of the analysis of the process of knowledge is being established. (shrink)

Over the last three decades, non-adaptationism has developed as an alternative model to more traditional, adaptationist approaches within Evolutionary Epistemology. Despite its great explanatory strength, non-adaptationist EE finds a potential Achilles heel in its adherence to conceptual relativism, namely the idea that empirical content can be relative to many different and radically incommensurable conceptual schemes. In his seminal essay “On the Very Idea of a Conceptual Scheme”, Donald Davidson did in fact prove the unintelligibility of an analogous form of conceptual (...) relativism. Although Davidson’s original intent was to debunk a conceptual relativist position which he discerned in the works of authors such as Kuhn, Quine, and Whorf, given the apparent similarity between the conceptual relativism supported by non-adaptationist EE and the one criticised by Davidson, one might well wonder if Davidson’s objections would have the same debunking effect if applied to non-adaptationist EE. In this paper I propose to answer this question by directing Davidson’s critiques of conceptual relativism to non-adaptationist EE and by testing to what extent the latter is de facto undermined by Davidson’s attacks. I demonstrate that Davidson’s arguments do not detract from the reliability of non-adaptationist perspectives and, to some extent, they appear to substantiate the non-adaptationist evolutionary epistemological cause anew.
