The starting point of Philosophia prima of Hobbes has as reference Physics and Metaphysics of Aristotle. The later development of his Philosophia prima, however, sets in motion a critique of Aristotelian metaphysics that will lead to a theoretical reorganization of a series of principles and concepts inherited from tradition. Considered as a whole, the first Hobbesian philosophy consists of a broad definition, that is metaphysics defined as the science of the entity as entity (instead of the classical definition of science of the being as being), on which are erected two strictu sensu definitions: metaphysics as general physics - to say the entity (ens) is to say the body (corpus) - and metaphysics as a representation. This paper is an effort to understand these and other questions related to studies Hobbesian on how we know the world, things and ourselves.
