Theory And Practice

The question of theory and practice has been one of the core issues discussed since the Renaissance of practical philosophy.This paper is not intended to make a comparative study of theory and practice on the diachronic dimension,but to focus on the republic itself and discuss Plato’s views on this issue and the response of later philosophers to Plato from the perspective of theory and practice.In the republic of the relationship between theory and practice of performance rule city-states by philosophers and their relations,the best city must be a philosopher Plato thought as a ruler or rulers philosophy research,visible unification on the basis of theory and practice of "philosopher king",so,the relationship between theory and practice can also be seen as philosophy and political relations.Specifically,in the republic,the intersection of theory and practice,or the unification of philosophy and politics,is accomplished through the exploration of justice,and Plato’s answer to justice is mainly illustrated through the argument of technique,which is the basic framework for the construction of an ideal city-state.But Plato in the republic also conveys the theory or the contemplation of the philosopher who lives in a hierarchy above the practice which is the political life of the city,so why does the philosopher descend to the city to rule? Moreover,does the "wisdom" that the philosopher sees outside the cave apply to the "wisdom" needed to rule the city-state? This led to different views of later philosophers.The introduction part of this paper briefly sorts out the reasons for modern people’s views on theoretical practice,clarifies the meaning of ancient Greek theory and practice,and shows the research methods of this paper.The first chapter discusses the establishment of the most beautiful city-state from Plato’s search for justice.The second chapter focuses on Plato’s discussion of "form",reveals the tension between theory and practice from the interpretation of "the metaphor of the cave",and tries to show that Plato has completed the unification of theory and practice in a certain citystate.The third chapter returns to the relationship between theory and practice.In this chapter,I will view this issue from the response of later philosophers.Aristotle’s distinction between the theory of wisdom and wise that wise is a special kind of intellectual ability,it is neither scientific,nor make,more is not meditation,but when it comes to good or bad things to people with a proper measure of the quality of the associated action,philosophical contemplation of life and of the city and his political life completely separate.
