Resumen

This paper attempts to develop certain of tyranny in Plato's Republic, Book IX. It takes into account not only the pleasures as principle of the dissolution of "logismos" but also the platonic intention of structuring the man's negative paradigm, its thinking, its affections, its actions -the tyrant-, as the opposite of the philosophical soul in its "celestial paradigm" or the man's paradigm, who uses "logismos", who has autarky and who knows what one's care is.
