The article presents the first comprehensive interpretation of the ergon argument in Aristotle’s Protrepticus. It further argues that Aristotle in this argument distinguishes the ergon of an entity from the ergon of its virtue thus presenting a complicated argumentative structure which is explicitly simplified in the Eudemian Ethics. Based on the latest attempts to reconstruct the Protrepticus, the article shows the relation of the ergon argument to its other versions in both Ethics. This account not only clarifies the relation of (...) the Protrepticus to Aristotle’s other ethical writings, it shows that Aristotle intends the argument as a transition between describing what human being does and what a good human being does well, namely a natural transition from the descriptive to the normative.

The following article is a contribution to the rich debate concerning happiness or fulfilment (eudaimonia) in Aristotle’s Nicomachean Ethics. It argues that eudaimonia is theōria in accordance with what Aristotle repeatedly says in Book X of the Nicomachean Ethics. However, happy life (eudaimōn bios) is a complex way of life which includes not only theoretical activity but also the exercising of other virtues including the so-called moral or social ones. The article shows that Aristotle differentiates between eudaimonia on the one (...) hand and the happy or fulfilled life (eudaimōn bios) on the other, and shows how this distinction clarifies Aristotle’s account of eudaimonia.

The following article reconstructs Plato’s argument for the existence of god in Laws X. The article starts with interpreting the argument for the priority of soul and continues with a discussion of the argumentation for rationality of the soul in charge of heavens . The view defended here is that Plato first defines the essential characteristics of the divine, namely self-motion and rationality, and then shows that there are entities which possess these characteristics and therefore deserve to be called gods (...) or divine. The article further shows that several sub-arguments mirror the structure of the overall proof. (shrink)
