Una versione progredita della teoria delle idee nel papiro di Ai Khanoum: una scoperta nella scoperta.

The paper firstly focuses on a rare vox, that is, the verb μετίσχω (‘to participate’). This has been found in two unexplored sources: the Π text of Lambda 1075b19 and the Ai Khanoum so called ‘papyrus’ in II.9, 11, IV.8-9. Using the verb μετίσχω with reference to the theory of ideas testifies for a subsequent phase to Plato’s middle dialogues in defining the theory and the related lexicon. (see Plato’s Parmenides 128e-130c). The phase was intermediate and probably transitory. Xenocrates is likely to have played a role, as Margherita Isnardi Parente hypothesizes. This allows for deeper connection between the Aristotelian theories and Plato's Academy.
