Wisdom flowers and spreads
Never before have human beings so benefited from membership in a sagacious, scientific, and increasingly virtuous civilization. Wisdom flowers and spreads… even as does silliness. Like the absurd assertion (repeated ad nauseam by left and right) that wisdom hasn’t grown! A damnable outright lie. This is a bona fide renaissance, threatening to make everything better, in all ways. A renaissance that must find every potentially lethal error and hence, ironically, benefits from endless criticism. Helpful, vigorous criticism — but not chic-cynical despair.
