One day a man approached Socrates and said,

“Do you know what I just heard about your friend?”

Socrates said,

“Before you talk to me about my friend, take a minute 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.”

The Second filter is the filter of Goodness.

            “Is what you are about to tell me about my friend something good?”

            “No, on the contrary.”
