“Everything changes; nothing remains without change”, said Siddhartha Gautama, while Harry Rowohlt held that at least Nothingness remains immutable. In Siddhartha, Herman Hesse observed that “the opposite of every truth is just as true”, an insight gleaned from Buddhist catechisms. It seems that all the world’s most profound thinkers—from Buddha to Socrates, from the Zen masters to Lao Tse—eventually arrive at the same conclusion: wisdom is rife with contradictions and truth cannot be compressed into words. Yet there is a steady flood of literature flaunting purportedly eternal truths, from self-help books down to proverbs and bon mots on calendars, aphorisms on greeting cards and quotes shared online. Smart-alec one-liners ring out from speeches and lectures—in short, pearls of wisdom are ubiquitous. Dietmar Bittrich offers a powerful antidote for all this enlightenment-mongering by juxtaposing contradictory wisdoms.
