There&rs;s a story about a proud young man who came to Socrates asking for knowledge. He walked up to the muscular philosopher and said, &ld;O great Socrates, I come to you for knowledge.&rd; Socrates recognized a pompous numbskull when he saw one. He led the young man through the streets, to the sea, and chest deep into water. Then he asked, &ld;What do you want?&rd; &ld;Knowledge, O wise Socrates,&rd; said the young man with a smile. Socrates put his strong hands on the man&rs;s shoulders and pushed him under. Thirty seconds later Socrates let him up. &ld;What do you want?&rd; he asked again. &ld;Wisdom,&rd; the young man sputtered, &ld;O great and wise Socrates.&rd; Socrates crunched him under again. Thirty seconds passed, thirty-five. Forty. Socrates let him up. The man was gasping. &ld;What do you want, young man?&rd; Between heavy, heaving breaths the fellow wheezed, &ld;Knowledge, O wise and wonderful...&rd; Socrates jammed him under again Forty seconds passed. Fifty. &ld;What do you want?&rd; &ld;Air!&rd; he screeched. &ld;I need air!&rd; &ld;When you want knowledge as you have just wanted air, then you will have knowledge.&rd;
