In ancient
Greece, Socrates was reputed to most knowledgeable person. One day a friend met
him and said, "Do you know what I just heard about your friend?"
"Hold on a minute," Socrates replied. "Before you talk to me
about my friend, it might be good idea to take a moment and filter what you’re
going to say. That’s why I call it the triple
filter test. The first filter is Truth.
Have you made absolutely sure that what you are about to tell me is true?"
"Well, no," the man said, "actually I just heard about it
and…"
"All right," said Socrates. "So you don’t really know if it’s
true or not. Now, let’s try the second filter, the filter of Goodness. Is what you are about
to tell me about my friend is something good?"
"Umm, no, on the contrary…"
"So," Socrates continued, "you want to tell me something bad
about my friend, but you’re not certain it’s true. You may still pass the test
though, because there’s one filter left—the filter of Usefulness. Is what you want to tell me about my friend
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?"
