An ancient Greek philosopher (circa 428-348 or 347 B.C.), one of only two whose writings are still extensively studied today (the other being his pupil Aristotle). He is referred to more frequently in Helena P. Blavatsky’s writings than any other philosopher and is identified, as is Confucius, both there and in The Mahatma Letters to A. P. Sinnett, as a “fifth Round man,” far advanced “psychically, mentally and spiritually” of the average person today (SD 1:162; Mahatma Letter 66 [Barker, 14]). His philosophical ideas are presented in a series of twenty-four dialogues, in most of which the main character is his teacher, Socrates. Thirteen letters are also attributed to him, though scholars believe most are forgeries, except the largely autobiographical seventh (and, some believe, at least parts of the third, eighth, and thirteenth). Plato also wrote a funeral oration, Menexenus, traditionally included in the seventh tetralogy along with the Greater and Lesser Hippias and the Ion. The speakers are Socrates and Menexenus, who is not to be confused with Socrates’s son of the same name (Wikipedia). The literary quality of his dialogues, especially from the early and middle periods, are unexcelled by any other Western philosopher, although some (notably Berkeley and Hume) attempted to write philosophy in that style.
