Wolfgang Stegmüller

Wolfgang Stegmüller (born June 3, 1923, Natters, Austria – died June 11, 1991, Munich, Germany), was a German-Austrian Philosopher with important contributions in philosophy of science and in analytic philosophy.

Biography

W. Stegmüller studied economics and philosophy at the University of Innsbruck. In 1944 he graduated as "Diplom-Volkswirt" and one year later he obtained a PhD in economics. Also at the University of Innsbruck he obtained in 1947 a PhD in philosophy. In 1949 he habilitated with the thesis "Sein, Wahrheit und Wert in der heutigen Philosophie".

After a stay of one year at the University of Oxford in 1954 he returned to the University of Innsbruck where he was appointed as associate professor for philosophy in 1956. After stays as visiting professor at the Universities of Kiel and Bonn he received a call from the Ludwig Maximilian University of Munich. Here in 1958 he was appointed professor for philosophy, logic, and philosophy of sciences and became director of the "Seminar II". Except for two stays at as a visiting professor in 1962/63 and 1964 at the University of Pennsylvania he remained in Munich and ran there a center for analytical philosophy until his retirement in 1990. From 1977 to 1979 he also was dean of the faculty for philosophy, philosophy of science, ans statistics.

Stegmüller was from 1966 on a corresponding member of the Austrian Academy of Sciences and from 1967 on a member of the Bavarian Academy of Sciences and Humanities. 1972 he became a member of the French Institut International de Philosophie, located in Paris. He also was a member of the International Academy of Science founded in 1980. In 1989 W. Stegmüller was awarded an honorary doctorate from the University of Innsbruck. After his retirement he was elected as honorary president of the Gesellschaft für Analytische Philosophie (Society for Analytical Philosophy).

Work

Stegmüller can be credited with essential contributiuons to the dissemination of if ideas of analytical philosophy ans philosophy of science in the German-speaking world. Akready in his inaugural lecture at Insbruck University, he outlined the four problems in epistemology, which should become the focus of his later work:

* The probelem of induction * The fundamenral role experience * The problem of theoretical concepts * The problem of scientific explanation

In the following his main ideas are summarized.

Logics

In his books "Das Wahrheitsproblem", "Idee der Semantik" (1957), and "Unvollständigkeit und Unentscheidbarkeit" (1959) Stegmüller disseminated the ideas of Alfred Tarski and Rudolf Carnap on Semantics and Logics as well as of Kurt Gödel on mathematical logic. Later similar works are on "Die Antinomien und ihre Behandlung" (1955) as well as "Strukturtypen der Logik" (1961).

Epistemology

One of the most influential books of Stegmüller is "Metaphysik, Skepsis, Wissenschaft" (1954). In this work, he discusses the epistemological foundations of metaphysics, scepticism, and science. He demonstrates that any search for epistemological fundamentals will necessarily lead to the problem of the evidence - which Stegmüller does not regard as solvable. He also refuses the potential solution that universal skepticism is self-refuting. Even if it was self-refuting, universal skepticism can be stated if the skeptic does not try to justify it. In consequence, explicit conditions ("Evidenzvoraussetzungen") are necessary in metaphysics as well as in science. This means that neither can be fundamentally justified but do presuppose a decision.

A further focus of Stegmüller's work was phenomenalism. In "Der Phänomenalismus und seine Schwierigkeiten" (1958), he describes the extreme problems, which hinder a stringent implementation of the phenomentalist program.

Philosophy of science

Stegmüller is regared as one of the leading philosophers of science of the second half of the 20th century. Deeply influenced by Thomas S. Kuhn and Joseph D. Sneed, he and several co-workers expanded upon the ideas of Sneed in order to overcome the prevalent rationality crisis of the science that was often regarded as a consequence of Kuhn's works. Furthermore, this led him to a new answer to the problems of theoretical concepts. This line of investigations is today known as philosophy of science structuralism.
