Plato´s Republic is maybe the most widely read philosophical work of all times. It is the earliest surviving, systematic utopia in Europe´s history and continues to inspire people today. But who did Plato want to address with his work and why? In this paper I will discuss these issues. My thesis is that Plato wanted to direct his Republic to people, men and women, who have a good character and love wisdom in order to make them to think radically differently from the traditional norms. If these would-be philosophers could challenge the old-fashioned way of seeing things they could take the lead to establish a just society. I will also discuss critically two alternative approaches from other philosophers.
