The German philosopher, Schopenhauer, was strolling along a street in Dresden, seeking the answers to questions that bothered him. Passing by a garden, he decided to sit and look at the flowers. One of the residents of the neighborhood observed the philosopher's strange behavior and summoned the police.
Minutes later, an officer approached Schopenhauer. "Who are you," the officer asked brusquely.
Schopenhauer looked the policeman up and down. "If you can help me find the answer to that question," he said, "I will be eternally grateful to you."
