Socrates
Ok, this was sent to me in an email, and I am fairly positive that it's not in any real way an anecdote about the real Socrates. However, it gives both good advice AND a reason to laugh. I figured that was reason enough to post it. Was he being wise, or foolish? You make the call:
In ancient Greece (469 - 399 BC), Socrates was widely lauded for his wisdom. One day the great philosopher came upon an acquaintance, who ran up to him excitedly and said, "Socrates, do you know what I just heard about one of your students...?"
"Wait a moment," Socrates replied. "Before you tell me, I'd like you to pass a little test. It's called the Test of Three."
"Test of Three?"
"That's correct," Socrates continued. "Before you talk to me about my student let's take a moment to test what you're going to say. The first test is Truth. Have you made absolutely sure that what you are about to tell me is true?"
"No," the man replied, "actually I just heard about it."
"All right," said Socrates. "So you don't really know if it's true or not. Now let's try the second test, the test of Goodness. Is what you are about to tell me about my student something good?"
"No, on the contrary..."
"So," Socrates continued, "you want to tell me something bad about him even though you're not certain it's true?"
The man shrugged, a little embarrassed.
Socrates continued, "You may still pass though because there is a third test - the filter of Usefulness. Is what you want to tell me about my student going to be useful to me?"
"No, not really..."
"Well," concluded Socrates, "if what you want to tell me is neither True nor Good nor even Useful, why tell it to me at all?"
The man was defeated and ashamed and said no more.
This is the reason Socrates was a great philosopher and held in such high esteem. It also explains why Socrates never found out that Plato was sleeping with his wife.
