Abstract
The present article consists of two parts: in the first one some clarifying, and about the context, commentaries are made about the origin of the three texts of Thomas Hobbes, of which a castilian version is presented, and they constitute the second and most important part of the article. As far as the first part of the article, it focuses on making evident the importance of those three texts, which are considered as representative of the period of youth of the author, and their role and place in the hobbesian political thought; as well as the relation of such thought with his works on natural science. For that reason the theme of method is a central one in said relation.
