Science would be ruined if (like sports) it were to put competition above everything else, and if it were to clarify the rules of competition by withdrawing entirely into narrowly defined specialties. The rare scholars who are nomads-by-choice are essential to the intellectual welfare of the settled disciplines.
Music is essentially useless, as life is.

Anger is an essential part of being human. People are taught to deny themselves anger, and in this, they are actually opening themselves up to hate. The more you deny yourself the freedom to be angry, the more you will hate. Let yourself be angry, and hate will disintegrate, and when hate disintegrates, forgiveness prevails! The more you deny that you are angry, in attempts to be "holy" the more inhuman you will become, and the more inhuman you will become, the harder it will be to forgive.
