The dubious notion that philosophy is a guide to calmer living is as old as the field itself. Saint Augustine described philosophy as a “harbor” for troubled souls in a fourth-century monograph on the happy life, and the sixth-century Roman senator Boethius titled the treatise he wrote while awaiting execution “The Consolation of Philosophy.” More recently, in his Philosophical Investigations (1953), Ludwig Wittgenstein suggested that the aim of philosophy is not to seek the truth but rather to provide relief—“to show the fly the way out of the fly-bottle.” Wittgenstein didn’t embrace “a single philosophical method.” Instead he concluded, “There are indeed methods, different therapies” to quiet the buzz of our puzzlement.
