Abstract
The present paper will discuss three points: (a) the question on if the fundamental mistakes that led Hegel’s system to collapse can be understood and formulated in the horizon that is given to us by the tradition from Plato to Schelling; (b) if it is posible to outline the project of a system in the tradition of Plato and Hegel in a way that the mistakes mentioned before can be avoided; (c) in being posible such a project, what role would play in it contemporary scientific theories, as the Theory of Evolution by Darwin, The theory of systems by Bertalanffy, the Theories about Deterministic Chaos, the Theory of Prigogine about Dynamic Systems and the Fractals Theory? In answer to this question the paper will defend the proposal of a project of universal philosophical system, in which these theories must be considered as its integer parts, such as mechanisms that, at least in part, determine the passage from the One to the Multiple. Key words: philosophical system; dialectic; scientific theories; neoplatonism; one; multiple.
