One day the great philosopher...

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 aboutone of your students?"
"Wait a moment," Socrates replied. "Before you tell me I'd like you topass a little test. It's called the Test of Three."
"Three?"
"That's right," 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?"
"Oh no," the man said, "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 youare about to tell me about my student something good?"
"No, on the contrary..."
"So," Socrates interrupted, "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?"
"Well it....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. This is the reason Socrates was a great philosopher and held in such high esteem.
It also explains why he never found out that Plato was having an affairwith his wife.

Michael Idvorsky Pupin

Born 4 Oct 1858; died 12 Mar 1935 at age 76. Serbian-American physicist who devised a means of greatly extending the range of long-distance telephone communication by placing loading coils (of wire) at predetermined intervals along the transmitting wire. His parents were illiterate, but they encouraged his education. Pupin became an instructor in mathematical physics (1890) at Columbia University, New York City. In 1986, he discovered that atoms struck by X rays emit secondary X-ray radiation. He also invented a means for taking short-exposure X-ray photographs. The Bell Telephone Company, in 1901, acquired the patent for his invention for long-distance telephony. Pupin won a Pulitzer Prize (1924) for his autobiographical work, From Immigrant to Inventor (1923).
