(This is a translation of Francesca Dalle’s answer )
Socrates had the reputation of being of great wisdom. One day someone came to visit him and said:
-You know what I just heard about your friend?- Wait a moment, replied Socrates, before you tell me, I would like to give you a test, that of the three sieves.- The three sieves?
– Before telling something about others, it is good to take the time to filter what you want to say. The first sieve is that of truth. Have you verified that what you are going to tell me is true?
– No, I only heard about it …
– Very well. So you don’t know if it’s true. Let’s continue with the second sieve, that of kindness. Is that something good you wanna tell me about my friend?
– Oh no, on the contrary!- So you want to tell me bad things about him and you don’t even know if they’re true. Maybe you can still pass the test, there is the third sieve left, that of utility. Does it help me to know what this friend would have done?
– Not really.
.- So, concluded Socrates, what you wanted to tell me is neither true, nor good, nor use
