"Socrates' method of engaging conversations with his fellow citizens has come to be known in history as the Socratic Dialectic or the Socratic Method, and its method of pursuing a given truth is still adopted by many university and public school teachers to the present day. It is the method that Plato adopted for the Republic and for all of his Dialogues."
“Dialectics is a term used to describe a method of philosophical argument that involves some sort of contradictory process between opposing sides. In what is perhaps the most classic version of “dialectics”, the ancient Greek philosopher, Plato, for instance, presented his philosophical argument as a back-and-forth dialogue or debate, generally between the character of Socrates, on one side, and some person or group of people to whom Socrates was talking, on the other. In the course of the dialogues, Socrates’ interlocutors propose definitions of philosophical concepts or express views that Socrates challenges or opposes."
