An Investigation of the Relationship between Knowledge, Virtue, and Happiness Using Plato's View

Knowledge, virtue, and happiness as issues that have always been of great importance in Plato's philosophical approaches, were used in constructing his utopia. The fundamental question of this paper is about the relationship between knowledge, virtue, and happiness according to Plato. The spirit of Plato's philosophy affirms the connection and alignment of virtue and knowledge with each other, and as it seems in Platonic thought, the onslaught of moral vices on the virtuous person will degrade his epistemology. Also, knowledge, as one of the foundations of human happiness, plays an essential role in his happiness. Knowledge and happiness are related to each other because, in the field of knowledge, human must be in the epistemological level of "Nous" to be like God by thinking in ideas.
