Die Araber und die antike Wissenschaftstheorie discusses the history of the development of Aristotelian argumentation in the Alexandrian neoplatonic school and in Arab philosophy, focussing on the Tabula Porphyriana. It treats the ever present role of specific questions in the Greek and Arab scholarly tradition.In the first part the three problems of the Eisagoge are explored: whether it is, what it is, how it is. The author shows that these questions were interpreted differently by various philosophical schools. The book then discusses another group of issues (whether it is, what it is, how and why it is), which determined the argumentation, the axiomatic ordering of the sciences, and concludes with a demonstration on the basis of concrete examples of how the fully-developed argumentation theory was employed in practice.
