By sheer accident, some are privileged Americans and some are starving Ethiopians. There is no Grand Order of life. There is no God putting people on Earth as a testing place, consigning the wicked to hell and the righteous to heaven. But we existentialists disagree. We think people simply are born as biological creatures, and subsequent conditioning by family and culture shapes each person's nature.
Existence precedes essence'' is a fundamental principle of our philosophy.
The universe is indifferent to you and me. If Southern whites lynch a black in a tree, the tree doesn't care. If a child dies of diphtheria, it is of no concern to the diphtheria microbes. Nature doesn't care. What we do may not matter to the universe, but it matters to our fellows.
