“Whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.” Phil 4:8
In ancient Greece, Socrates was reputed to hold knowledge in high esteem.
One day an acquaintance met the great philosopher and said, “Socrates, do you know what I just heard about your friend?”
“Hold on a minute,” Socrates replied. “Before telling me anything, I’d like you to pass a little test. It’s called the ‘Triple Filter Test.'”
“That’s right,” Socrates continued. “Before you talk to me about my friend, it might be a good idea to take a moment and filter what you’re going to say. The first filter is ‘Truth.’ Have you made absolutely sure that what you are about to tell me is true?”
“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 something good?”
“No, on the contrary … “
“So,” Socrates continued, “you want to tell me something bad about him, 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?”
The acquaintance was silent.
