Since the 19th century the theory of evolution has been the guide not only of biological research, but of the explanation of man's psychic and mental abilities, too. In particular Herbert Spencer's and Charles Darwin's works gave rise to an evolutionary view of human mind (evolutionary psychology). This view was generalized to the explanation of epistemic structures like science and was adopted by many philosophers and scientists, e. g. Boltzmann, Mach, and others. Under the influence of Darwin's theory of natural (...) selection a selective elimination model was established in order to explain epistemic activities. Thus, in the 19th century we find expressed the basic ideas of today's evolutionary epistemology. The modern evolutionary theory of (human) knowledge therefore turns out to be the more precise and elaborated formulation of the fundamental postulates of an evolutionary psychology. (shrink)

Popper's methodology does not entail any playing down of the various indispensible distinctions such as the distinction between knowing and guessing, the distinction between myth and science, the distinction between the observational and the theoretical, and between the vernacular and technical sublanguages or technical vocabulary. By avoiding both the totalization that led to the foundationalist position and the scepticist reactions to these frustrated foundationalist hopes, Popper's methodology makes it possible to combine fallibilism with a realist view of theories. It combines (...) the perennial willingness to re-examine positions, statements, etc. with the claim that a particular theory (as an item of knowledge in the objective sense) constitutes cognitive progress over its rivals. However, some of his formulations have been deliberately provocative and in this way have given rise to certain misgivings about possible paradoxical implications, even in philosophers congenial with Popper's approach. The concept of knowledge in the objective sense is, of course, an explicatum which Popper proposes primarily for use in methodology and epistemology. The concept is an expression of the acknowledgment of fallibility in principle. The phrasing that ‘knowledge is conjectural’ or ‘knowledge is fallible’, even when it refers to knowledge in the objective sense, is but an abbreviation for: since our methods for ascertaining the truth-value of a particular statement about empirical reality are fallible in principle, there cannot be any certain knowledge about reality. In everyday life and in politics tolerance will be possible to the extent to which the recognition of this fallibility is more than a declaration. (shrink)

Fundamentismus und Skeptizismus-Anarchismus sind zwei entgegengesetzte Positionen in der traditionellen Erkenntnistheorie und in der modernen Wissenschaftstheorie. Zwischen ihnen gibt es einen dritten Standpunkt, den Evolutionismus. Beispiele sind zwei neuere Arbeiten von Putnam und Stegmüller . Im Gegensatz zum logisch-statischen Fundamentismus berücksichtigt der Evolutionismus auch dynamische und naturalistische Ansätze. Stegmüller folgend entlehnen wir in der vorliegenden Untersuchung aus der Sprachphilosophie pragmatische Gesichtspunkte, um die logische Syntax und Semantik, die Werkzeuge des Fundamentismus, zu ersetzen. Wir zeigen die Kraft der Pragmatik bei der (...) Behandlung von Problemen wie Erkenntniswachstum, Begriffswechsel, Theorien- und Bedeutungsdynamik, wissenschaftliche Entdeckung und besonders beim Problem der Inkommensurabilität. Unser nicht-fundamentistischer Vorschlag ist ein heuristisches Modell, das auf der modernen genetischen Theorie basiert. (shrink)

Popper's thesis that the growth of knowledge lies in the emergence of problems out of criticism and takes place in an autonomous world of products of the human mind (his so-called world-3) raises two questions: (1) Why does criticism lead to new problems, and (2) Why can only a limited number of tentative solutions arise at a given time? I propose the following answer: Criticism entails an overlooked evolutionary world-3 mechanism, namely, the migration of piece meal conceptual schemes from one (...) research tradition to another. Popper by passed the questions above because he relied very heavily on the selective power of criticism. (shrink)

There are two interrelated but distinct programs which go by the name evolutionary epistemology. One attempts to account for the characteristics of cognitive mechanisms in animals and humans by a straightforward extension of the biological theory of evolution to those aspects or traits of animals which are the biological substrates of cognitive activity, e.g., their brains, sensory systems, motor systems, etc. (EEM program). The other program attempts to account for the evaluation of ideas, scientific theories and culture in general by (...) using models and metaphors drawn from evolutionary biology (EET program). The paper begins by distinguishing the two programs and discussing the relationship between them. The next section addresses the metaphorical and analogical relationship between evolutionary epistemology and evolutionary biology. Section IV treats the question of the locus of the epistemological problem in the light of an evolutionary analysis. The key questions here involve the relationship between evolutionary epistemology and traditional epistemology and the legitimacy of evolutionary epistemology as epistemology. Section V examines the underlying ontological presuppositions and implications of evolutionary epistemology. Finally, section VI, which is merely the sketch of a problem, addresses the parallel between evolutionary epistemology and evolutionary ethics. (shrink)

Karl Popper’s world 3 theory proposes that the products of the human mind can be considered a third world, partially autonomous of the mental and physical worlds, and real, because it can produce effects on both. When he first introduced the idea in 1960, he took even his close colleagues and students by surprise. Yet tracing the development of his idea shows a great deal in Popper’s previous work and thought led up to what seemed his startlingly new proposal. And (...) far from being the philosophy of his dotage, as some sneered, his world 3 proposal, once fully shaped, became a keystone of his thought. (shrink)
