ABSTRACT
A highly regarded contribution to the development of a theory of argumentation is made by the Belgian philosopher Chaim Perelman and his compatriot Lucie Olbrechts-Tyteca. Perelman (1912–1984) was professor of logic, ethics and metaphysics at the University of Brussels. Having studied first law and then philosophy, he completed the latter study with a thesis on the German logician Frege. His associate Olbrechts-Tyteca (1900–1987) read social science and economics. They started to do research together into rhetoric and argumentation in 1947. 106
