Work of Plato reached to us as 34 dialogues, 13 letters and compositions of "Determination", here part from them is exposed to the doubt by the row of researchers in their belonging to the feather of genius. In addition, 25 epigrams (short elegant poems) and information were saved about young Аристокле (the real name of philosopher, and the name "Plato" to him, allegedly, Socrates gave after mighty build) as a successful writer of poetic works of different genre, including comedies and tragedies that he burned out after an acquaintance with Socrates.But even that we have, strikes the depth of immersion in the article of research and wide scope.
