L was on his way to see his old science teacher at the University of California. As he was approaching the university he saw a friendly man giving a lecture outside the gate of the school. The man had on a dress shirt with no tie, and his shirt was not tucked in. He appeared to be about 43, his hair was messy, and he looked like he hadn't showered in weeks, seeming unfit to be a teacher at the university. As I approached him, he said to me, "When people are born, they are naturally good. Their natural instincts are similar, though they differ based on custom. Proper teaching is essential to ensure their good nature remains intact. Long ago, the father of this school sought an appropriate environment for children like you!" L, who is a philosopher and enjoys playing with people's ideas, responded, "You should know that I am not a very nice person. If there was an unfortunate incident in America that killed 1 million people, it wouldn't bother me at all." The man shook his head and said, "That is vile and evil!" L countered, "But there is something we should care about, like having a good sense of who you are. It is the most important thing in the world to me." The man replied, "It is not good for a child like you to go without learning. If one does not learn when young, what can one accomplish in old age? A jewel of natural beauty without polish is useless!" L retorted, "That's ridiculous, old man! All around the world, people live seemingly peaceful lives. They believe themselves to be virtuous, just like you! Darkness lurks in the pit of everyone's heart, their light is a total force!" The silence between them was loud, and they parted ways, heading in separate directions.
