I had had my night of weeping...I had purged myself of useless emotions that terrible night, now every nerve every sinew, every thought was bent on a single purpose.

We are biological creatures. We are born, we live, we die. There is no transcendent purpose to existence. At best we are creatures of reason, and by using reason we can cure ourselves of emotional excess. Purged of both hope and fear, we find courage in the face of helplessness, insignificance and uncertainty.

The way you really find out about the performer's seriousness about the cause is how long they stay with it when the spotlight gets turned off. You see a lot of celebrities switch gears. They go from the environment to animal rights to obesity or whatever. That I don't have a lot of respect for.
