Socrates believed that knowledge should be held in high esteem. He developed the "Triple Filter Test" to determine whether information passed three important filters - truth, goodness, and usefulness - before being shared. When an acquaintance approached Socrates with gossip about a friend, Socrates applied the three filters, and the acquaintance admitted that what they had heard did not pass the tests of truth, goodness, or usefulness. Socrates concluded there was no reason to share information that failed all three filters. The visitor was impressed by the lesson of only spreading information that has value.
