The universe is a closed system which functions only by cause and effect. Man is basically a highly evolved animal. Human death is merely the ceasing of biological life, including the extinction of personality. In this view, no human spirit, personality or mind continues beyond the death of the body. At death, human existence ends totally, except perhaps figuratively in the memory of others, and in genes passed down to offspring.
All values are self-determined by man, and only exist in the mind of man.
There is no natural moral law, and no absolute standard of right and wrong. Ethics stems from human need and interest. History is an unrepeated line of events related by cause and effect, without a real purpose. There is no overall purpose or meaning to the course of history, and no goal to which it is heading. History and human events only have whatever meaning humans may give to them.
