"Is it true," asked the student, "that the gods only have power because we believe in them?"

"Yes," said the sage.

"Then why not appear openly? How many more people would believe in the Thunderer if, upon first gaining enough worshipers to cast lightning at all, he struck all of the worst criminals and tyrants?"

"Because," said the sage, "the gods only gain power through belief, not knowledge. You know there are trees and clouds; are they thereby gods? Just as lightning requires close proximity of positive and negative charge, so divinity requires close proximity of belief and doubt. The closer your probability estimate of a god's existence is to 50%, the more power they gain from you. Complete atheism and complete piety alike are useless to them."
