Harvey shares his philosophy. He favors indeterminism--the idea that there are no rules that govern the world (the only rule he thinks that exists is chance). Why should he be moral if he believes that there are no moral laws?
In a dinner with his upper-class friends, a man confesses that he believes in luck to be the most important factor in governing fate. He argues that science and reality are largely determined by random chance. This idea is in line with philosophical indeterminism, the idea that not everything is predetermined with a meaning.
