George W. Bush might not agree that he is an existentialist, but most of the existentialists also rejected the suggestion that they be dumped into that category.
Sartre said: "Man is nothing else but what he makes of himself. Such is the first principle of existentialism." Thus if a man becomes the Commander-in-Chief by fiat of the United States Supreme Court, that's just as good and better than being elected by the voters.
Can we get a witness from Nietzsche? In "<em>Thus Spoke Zarathustra</em>," Nietzsche said: "But thus I counsel you, my friends: Mistrust all in whom the impulse to punish is powerful. They are people of a low sort and stock; the hangman and the bloodhound look out of their faces. Mistrust all who talk much of their justice! Verily, their souls lack more than honey. And when they call themselves the good and the just, do not forget that they would be Pharisees, if only they had - power." Sometimes, by God, they get it!
So would that be referring to the members of the Bush family?
When Camus said "You know what charm is: a way of getting the answer yes without having asked any clear question" was he referring to the Dubya challenge to America: "Come on, what say, we invade Iraq!"?
Wasn't saying "I'm the decider" tantamount to openly declaring himself to be an Existentialist of the highest rank and thus qualified to be considered for a place in the Existentialists Hall of Fame?
