For Vossius, the chain represented the inter-relationship of all the arts and sciences; the chain which connects the knowledge of particulars in the separate fields is the chain of philosophy.2Here, I want to bind together all the arts and sciences as represented by the multidisciplinary fellowship of the European Academy. Since I can't do it myself with Zeus' cosmic chain, nor indeed one bestowed upon me by Alexander the Great, then at least I can try to do it with a twenty-first-century celebration of Aristotle's towering achievements and with thoughts about how we can benefit from one of most ground-breaking ideas - potentiality. 2017 is the 2400th anniversary of Aristotle's birth in 384 BCE in Stagira, the eastern prong of the triple Chalkidiki peninsula in the northern Aegean Sea. According to Plato's idealist model of the universe, what we apprehend by the senses in the physical world is itself but a pale and inferior imitation of the real world, which consists of eternal, unchangeable, immaterial ideas or forms. Humans as a species share certain kinds of potential, but Aristotle saw different categories of human as possessing different kinds and levels. ...children (by which he means boys) are not yet capable of rational deliberation, but are fully endowed with the potential for it. Since the end of the city-state as a whole is to ensure that its citizens live the good life, it is manifest that education should be one and the same for all, and that it should be public, and not private - not as at present, when everyone looks after his own children separately, and gives them separate instruction of the sort which he thinks best; the training in things which are of common interest should be the same for all.
