Socrates(苏格拉底)was famous for his great learning.One day,an acquaintance(熟人)met him and said,\\\\\\\"Do you know what I just heard about your friends\\\\\\\" \\\\\\\"Hold on a minute,\\\\\\\"Socrates said.\\\\\\\"Before telling me anything,I want you to have a test.It’s called the Triple Filter Test(三重过滤测试).\\\\\\\" \\\\\\\"Triple filter(过滤)\\\\\\\" \\\\\\\"That\\\\\\\'s right,\\\\\\\"Socrates continued.\\\\\\\"Before you talk to me about my friend,it might be a good idea to take a moment and filter what you\\\\\\\'re going to say.That\\\\\\\'s why I call it the triple filter test.The first filter is Truth.Are you sure the thing you are about to tell me is true\\\\\\\" \\\\\\\"No,\\\\\\\"the man said,\\\\\\\"Actually I just heard about it and...\\\\\\\" \\\\\\\"All right,\\\\\\\"said Socrates.\\\\\\\"So you don\\\\\\\'t really know whether it\\\\\\\'s true or not.Now is the second filter.Is the news about my friend something good\\\\\\\" \\\\\\\"Not really.\\\\\\\" \\\\\\\"Well,\\\\\\\"concluded(推断,断定)Socrates,\\\\\\\"If what you want to tell me is neither true nor good nor even useful,why tell it to me\\\\\\\"
