Gods are fragile things, they may be killed by a whiff of science or a dose of common sense. They thrive on servility and shrink before independence. They feed upon worship as kings do upon flattery. That is why the cry of gods at all times is “Worship us or we perish.” A dethroned monarch may retain some of his human dignity while driving a taxi for a living. But a god without his thunderbolt is a poor object.
