A much-maligned feature of ancient and medieval political thought is its tendency to appeal to nature to establish norms for human communities. From Aristotle's claim that humans are "political animals" to Aquinas' invocation of "natural law," it may seem that pre-modern philosophers were all too ready to assume that whatever is natural is good, and that just political arrangements must somehow be natural. The papers in this collection show that this assumption is, at best, too crude. From very early, for instance in the ancient sophists' contrast between nomos and physis, there was recognition that political arrangements may be precisely artificial, not natural, and it may be questioned whether even such supposed naturalists as Aristotle in fact adopt the quick inference from "natural" to "good." The papers in this volume trace the complex interrelations between nature and such concepts as law, legitimacy, and justice, covering a wide historical range stretching from Plato and the Sophists to Aristotle, Hellenistic philosophy, Cicero, the Neoplatonists Plotinus and Porphyry, ancient Christian thinkers, and philosophers of both the Islamic and Christian Middle Ages.

In the epistemology of his middle period, Plato repeatedly describes the alleged ‘intellection of true reality’ in terms of sight, vision, illumination, or touch. Does this show more than Plato’s preference for optic and haptic metaphors? Should we assume that this goes back to a specific reason to be found in his underlying epistemological position? On the traditional reading, Plato actually wants to defend a sort of intuitionism. According to this still wide-spread reading, he claims that there is a very particular way of grasping Forms: Philosophers manage to come into a sort of direct contact with intelligible objects. Intellection is thus conceived as a quasi-visual presence of intelligible Forms. In our contribution, we want to challenge this interpretation by raising several objections against it. Surprisingly, there exists a close parallel in Aristotelian scholarship: Although Aristotle’s epistemology is built on considerably different foundations, there is an interpretative tradition according to which one has to assume a strict discontinuity between the methodical procedure and the intellection of the highest epistemic objects. As for Plato, we want to refuse an interpretation of Aristotle based on a concept of intuition characterized by the following features: Intuition is a specific way of gaining knowledge. It is independent of empirical conditions and leads to apriori knowledge. It consists of some experience of evidence or is accompanied by it. Knowledge gained by this kind of intuition does not need any further argument or justification

In der modernen philosophischen Handlungstheorie finden sich nur wenige Theoretiker, die sich in ihren zentralen Punkten explizit auf bestimmte Thesen des Aristoteles berufen. Roderick Chisholm, der versucht hat, durch direkten Import der aristotelischen These vom unbewegten Beweger das Determinismusproblem in der Handlungstheorie kausaltheoretisch zu lösen, ist eine Ausnahme von dieser Regel. Gleichwohl war und ist Aristoteles in vielen handlungstheoretischen Debatten gegenwärtig. Sein Einfluss wird sichtbar besonders bei den drei führend an der Ausbildung der modernen analytischen Handlungstheorie beteiligten Personen nämlich Gilbert Ryle, Elizabeth Anscombe und Donald Davidson.
