For years, Friedrich Nietzsche wasn’t taken seriously as a philosopher. Indeed, many didn’t regard him as a philosopher at all. He was instead dismissed as a clever provocateur – a witty aphorist who composed eccentric books replete with pithy observations and vertiginous tirades. He mixed ecstatic tones with convulsive invective, all collected under arresting titles such as Beyond Good and Evil, Twilight of the Idols and The Antichrist.
