Through other actions, other ideas and other ways of living, dissidence is the human possibility of not being part or forming part of the system of values, representations and relationships to which one was destined or which appears ineluctable. Deviation from the pre-assigned, from what should be thought or believed, from the biographical, philosophical or political course that should be followed, to dissent is to break with what is imposed and with impostures for an exploration without guarantees of what we still do not know. Every religion, political group or philosophical school -every society, in short- hosts, latent or in act, the movement of dissidence, of non-acceptance and the fracture in the center of what seeks to remain orthodox.

Spinoza's was a dissident philosophical life, though not a 'philosophy of defection'. A deserter is the one who abandons, the one who moves away, the one who renounces his place -his two fundamental remissions are war and school- and his functions or tasks. Desert is the abandoned, the territory that is completely deserted. Spinoza's is not a philosophy of desertion but of dissidence because his rupture does not abandon the place nor does it hide the work on it; if it breaks, it is to start, explore and generate in another way. It will be a rupture that is not autonomous from the question of how to live-together.
