Green's Blue Flame Gas is a locally owned and operated propane company that is as established as its native Houston owners and family of loyal employees.We pride ourselves in claiming to be a full service propane company, and we are even more proud to be serving the southeast Texas communities that we live in.

We also are introduced to the ideal of "Platonic love:" Plato saw love as motivated by a longing for the highest Form of beauty—The Beautiful Itself, and love as the motivational power through which the highest of achievements are possible. One of Plato's uncles (Charmides) was a member of the notorious "Thirty Tyrants," who overthrew the Athenian democracy in 404 B. Plato's relatives were not exclusively associated with the oligarchic faction in Athens, however.

According to doubtful stories from later antiquity, Dionysius became annoyed with Plato at some point during this visit, and arranged to have the philosopher sold into slavery (Diod. His uncle/brother-in-law Dion persuaded the young tyrant to invite Plato to come to help him become a philosopher-ruler of the sort described in the 338a-b). Dion accepted the condition and encouraged Plato to go immediately anyway ( 339a-b and next section) on board begging Plato to return to Syracuse.

Dion and Plato stayed in Athens for the next four years (c. Partly because of his friend Dion's enthusiasm for the plan, Plato departed one more time to Syracuse.

Later (at 3.6), Diogenes says that Plato was twenty-eight when Socrates was put to death (in 399), which would, again, put his year of birth at 427. Both sides of the family claimed to trace their ancestry back to Poseidon (D. We can be confident that Plato also had two older brothers, Glaucon and Adeimantus, and a sister, Potone, by the same parents (see D. "Plato" seems to have started as a nickname (for or "broad"), perhaps first given to him by his wrestling teacher for his physique, or for the breadth of his style, or even the breadth of his forehead (all given in D. Plato occasionally mentions Egypt in his works, but not in ways that reveal much of any consequence (see, for examples, According to the account given there, Plato first went to Italy and Sicily when he was "about forty" (324a). (This is where we get our word, "academic." The Academy got its name from its location, a grove of trees sacred to the hero Academus—or Hecademus [see D. 3.7]—a mile or so outside the Athenian walls; the site can still be visited in modern Athens, but visitors will find it depressingly void of interesting monuments or features.) Except for two more trips to Sicily, the Academy seems to have been Plato's home base for the remainder of his life.

In spite of the confusion, the dates of Plato's life we gave above, which are based upon Eratosthenes' calculations, have traditionally been accepted as accurate. According to Diogenes, whose testimony is notoriously unreliable, Plato's parents were Ariston and Perictione (or Potone—see D. While he stayed in Syracuse, he became the instructor to Dion, brother-in-law of the tyrant Dionysius I. The first of Plato's remaining two Sicilian adventures came after Dionysius I died and his young son, Dionysius II, ascended to the throne. Dionysius then summoned Plato, but wished for Dion to wait a while longer.
