Mechanism of relativism. We live in the best possible world (or everything is clearly inevitable)
In Voltaire’s classic novel Candide, Dr. Pangloss is a teacher of “metaphysico-theologo-cosmolo-nigology” who believes he lives in the best of all possible worlds.
"It is clear," he said, "that things cannot be other than the way they are; for as all things have been created for some end, they must necessarily be created for the best end. For instance, noses were made to support spectacles, hence we wear spectacles. Legs, as anyone can see, were made for breeches, and so we wear breeches. Stones were made to be shaped into castles; thus My Lord has a fine castle because the greatest baron in the province ought to have the finest house. And because pigs were made to be eaten, we eat pork all year round. So those who say that everything is well are speaking foolishly; they should say that everything is best"
