THE TRIPLE-FILTER TEST BY SOCRATES
One day, a student came up to the great philosopher. “Socrates, I have just heard some news about one of your friends.” he excitedly exclaimed.
“Before you tell me this news, we need to make sure that it passes the triple filter test,” responded Socrates.
“What’s the triple filter test?” the man asked.
“The first test is that of truth. Tell me, do you know that what you’re going to tell me is absolutely true?” asked Socrates.
After thinking for a moment, the man said, “I heard this news from someone else, so I’m not 100% sure if it’s true.”
