Nonetheless, it is plain that no influence on Plato was greater than that of Socrates.
This is evident not only in many of the doctrines and arguments we find in Plato's dialogues, but perhaps most obviously in Plato's choice of Socrates as the main character in most of his works.
Plato is one of the world's best known and most widely read and studied philosophers. There are varying degrees of controversy over which of Plato's works are authentic, and in what order they were written, due to their antiquity and the manner of their preservation through time.
Because they tended to distract us into accepting less than our highest potentials, however, Plato mistrusted and generally advised against physical expressions of love. These dates, however, are not entirely certain, for according to Diogenes Laertius (D. If Plato's date of death is correct in Apollodorus' version, Plato would have been born in 430 or 431. His stepfather Pyrilampes was said to have been a close associate of Pericles, when he was the leader of the democratic faction. When Socrates died, Plato left Athens, staying first in Megara, but then going on to several other places, including perhaps Cyrene, Italy, Sicily, and even Egypt.
It is widely accepted that Plato, the Athenian philosopher, was born in 428-7 B. E and died at the age of eighty or eighty-one at 348-7 B. L.), following Apollodorus' chronology, Plato was born the year Pericles died, was six years younger than Isocrates, and died at the age of eighty-four (D. Diogenes' claim that Plato was born the year Pericles died would put his birth in 429. Diogenes' report that Plato's birth was the result of Ariston's rape of Perictione (D. 3.1) is a good example of the unconfirmed gossip in which Diogenes so often indulges. Plato's actual given name was apparently Aristocles, after his grandfather. Although the name Aristocles was still given as Plato's name on one of the two epitaphs on his tomb (see D. Strabo (17.29) claims that he was shown where Plato lived when he visited Heliopolis in Egypt. In any event, Plato returned to Athens and founded a school, known as the Academy.
Aristotle ( 143c, Plato announces through his characters that he will abandon the somewhat cumbersome dialogue form that is employed in his other writings.
Since the form does not appear in a number of other writings, it is reasonable to infer that those in which it does not appear were written after the Scholars have sought to augment this fairly scant evidence by employing different methods of ordering the remaining dialogues.
Plato, perhaps now completely disgusted with politics, returned to his beloved Academy, where he lived out the last thirteen years of his life. His grave, however, has not yet been discovered by archeological investigations. There can be no doubt that Plato was also strongly influenced by Parmenides and Zeno (both of Elea), in Plato's theory of the Forms, which are plainly intended to satisfy the Parmenidean requirement of metaphysical unity and stability in knowable reality.
