And then we can get to that through rational thinking and planning. It was said that when Plato met Socrates, after he was introduced to the Socratic method and learned a little bit, he burned all of his previous writings because he was so out of whack before he met Socrates. All right, guys, our last of the great Greek philosophers is going to be Aristotle, who was called the master, the great thinker, the philosopher. When you're called the philosopher, you must be pretty good at philosophy. He's born in 384 BCE and at the age of 18, he goes to the great academy of Athens where he is a student of Plato's. And of course, he's going to be exposed in all of the different disciplines at that time period and he's going to excel. It's said that he was the best of Plato's students and he stays there till he's 37 when Plato passes away in 343 BCE.
