In ancient Greece Socrates had a great reputation for wisdom. One day someone came to see the great philosopher, and he said to him: – “Do you know what I just heard about your friend?” – “One moment” – replied Socrates – “Before you tell me about it, I would like to give you a test, the one with the three sieves.” – “The three sieves?” – “But yes” – continued Socrates – “Before telling everything about others, it is good to take the time to filter what one would like to say. I call it the three sieve test. The first sieve is the truth. Have you checked if that What are you going to tell me, is it true?” – “No… I’ve only heard about it…” – “Very good. So you don’t know if it’s the truth. Let’s continue with the second sieve, that of goodness. What you want to tell me about my friend, is it something good?” – “Oh no! On the contrary.” – “So” – continued Socrates – “You want to tell me bad things about him and you’re not even sure if they are true. Maybe you can still pass the test, the third sieve remains, that of usefulness. It is useful that I know what I would this friend have done?” – “No, really.” – “Then” – concluded Socrates – “what you wanted to tell me is neither true, nor good, nor useful; why did you want to tell me?” Moral: if everyone could meditate and put this little test into practice, the world would most likely be a better place.
