Plato, a philosopher in classical Greece, wrote extensively and on a variety of subjects. His writings can be divided into three distinct periods. Between 399-381 bce, he wrote of his travels in the Mediterranean region and composed the dialogues that distil the philosophy of Socrates. These texts include Apology of Socrates, Protagoras, Euthyphro, Hippias Major and Minor and Ion. In the second period, Plato decided to write in own voice about the individual and society, and the ideals of justice and courage as fundamental to the functioning of the state. Republic, his best known work, was written during this time. The last phase of his writing consists of his exploration of metaphysical ideas as well as the role of art in life.
Plato died in 347 bce.
