Plato of Athens is an ancient Greek philosopher, student of Socrates, teacher of Aristotle. It is from Plato that philosophy is formed as a system of knowledge. “Man is the measure of all things.” Or not? Socrates argues about this with the Sophist philosophers in the Protagoras, defending the goodness of the gods, but not of man, and revealing to his opponents the concept of virtue, which is the highest knowledge. The collection also includes Plato’s works “Theagus”, “Menexenus”, “Euthydemus”, “ Gorgias", "Meno". These Socratic works take the form of dialogues, in which, through the method of questions and answers, the problems of education and the principles of education, knowledge and ignorance, truth and lies, chaos and order, good and evil are clarified.
