Harald Wohlrapp
Harald R. Wohlrapp (born June 6, 1944 in Hildesheim, Germany) is a German philosopher. His main focus is argumentation theory. Philosophy 
Harald Rüdiger Wohlrapp was a student of the German philosophers Wilhelm Kamlah and Paul Lorenzen (Methodical Constructivism, Erlangen School). After studies (philosophy, social sciences, linguistics) in Freiburg, Paris and Erlangen, Wohlrapp was appointed to a teaching position at the university of Hamburg, where he was a professor of philosophy from 1983 through 2009 and is presently a senior research fellow. His main areas of interest lie in dialectics (Plato, Hegel, Marx), pragmatism (Peirce, Mead, Hugo Dingler), philosophy of science (Lorenzen, Feyerabend) and philosophy of language (Wittgenstein, Kuno Lorenz). The pervading concern of his efforts, however, is the philosophy of argument. The results of 25 years of work are laid down in his book The Concept of Argument, an extensive volume that begins with an outline and evaluation of the origin of argumentation theory in Aristotle’s philosophy and culminates with an integration of the transcendent core of secular reason into the understanding of argumentation. Argumentation Theory 
Wohlrapp takes argumentation to be the secret medium of any progress in academic and public thinking, a medium that deserves increasing attention in the growing complexity of the modern world. Thus, he welcomes the rise of the new academic field of argumentation theory, but at the same time points to its ongoing imprint by the Aristotelian legacy. This leads to a focus on inference and persuasion, and to a lack of understanding the dynamic and subjective traits of argumentative practice as well as to a neglect of its urgent need of a substantial conception of human reason. Argumentation is seen by Wohlrapp as a practice located in inquiry (in ordinary life, in science and in philosophy), its general task being the overcoming of gaps and deficits in orientation with the help of constructing and examining new theoretical elements, i.e. with claiming theses, justifying them with proven elements of theory and defending them against objections: 
 
 A thesis is judged „valid“ if its justification can be worked out „free from objections“ in front of an „open forum of arguments“. With this conception a new and realistic concept of knowledge in its historical character is available. Valid theses can become knowledge as they go on proving reliable orientations in actions and so gradually become part of the reality of life. The second part of Wohlrapp’s conception of argument is the integration of subjectivity. The shape of theses and arguments in argumentative practice usually bears a subjective imprint. This can be theorized with the help of the sociological frame concept, allowing thus the treatment of more or less deep differences in the presented views of issues. The completion of this subjective trait is the third new part of Wohlrapp’s concept, namely formulation of a principle of argumentative reason. It is taken from Paul Lorenzen’s philosophy and is called the „Principle of Transsubjectivity“. Wohlrapp has been using his views in the analysis and assessment of problems in philosophy of science, politics, applied ethics and theories of religion. He was thus able to produce some results which have won some interest by the academic public. Selected publications
