Hen epi pollon. The Origin of Husserl’s Eidetic Variation and the Divide Between Plato and Aristotle on the Universal

It is commonly known that Husserl’s eidetic variation is of paramount importance for phenomenology. For if phenomenology is a science of pure essences and formulates scientific laws about such essences, there has to be something like a method to follow in order to discover and test such eidetic truths; and this method is dubbed as eidetic variation. Now, a crucial aspect of this method has not been under active consideration yet: namely, as Husserl stresses in Experience and Judgment, that the eidetic variation is somehow to be related to the Greek notion of “hen epi pollôn”: the one over the many. An expression first used by Aristotle in the context of his dispute with Plato on the status of intelligible objects as universals. Accordingly, it seems clear that, by using this expression, Husserl wanted to refer his method to this Aristotle/Plato divide. The aim of this paper is to take this claim seriously, and to show, by an historical detour which takes into consideration this dispute, in which sense this method can be considered as a crucial contribution to the tradition to which phenomenology belongs, namely the Platonic-Aristotelian tradition.
