Friedrich Nietzsche is one of history’s most misinterpreted philosophers, and it isn’t hard to understand why; his lengthy writings are sometimes obscure and it isn’t always clear what he’s getting at.

It can be easier to grasp Nietzsche’s big ideas by studying his aphorisms — succinct yet insightful statements — which he intentionally penned at times (some of his works contain sections devoted to just such sayings). The punchy format of aphorisms fit the terse, strength-focused ethos of Nietzsche’s philosophy perfectly, and he explicitly said his “ambition [was] to say in ten sentences what others say in a whole book.”

The pithiness of his aphorisms shouldn’t be mistaken for simplicity, however. Nietzsche liked the aphorism because its meaning wasn’t one-dimensional, but could encompass layers of irony, sarcasm, and nuance which reward the reader who goes beyond the surface to contemplate deeper meanings.

Many of Nietzsche’s aphorisms have become standard sayings in popular culture. “What doesn’t kill me makes me stronger,” has been used by football coaches to motivate players during grueling summer workouts and by Kanye West in one of his biggest hits Many of Nietzsche’s other aphorisms have been adopted by artists looking to inspire themselves to reach for bigger and bolder visions, which was part of his intent; while the philosopher’s work has often been interpreted in a societal and political context, his themes on the will to power and waging war are frequently meant as metaphors for creative and intellectual struggle.

Indeed, many of Nietzsche’s aphorisms are designed to jostle the individual out of existential complacency. He doesn’t want people to simply sleepwalk through life. You can feel Nietzsche grabbing you by the shirt collar and slapping you awake as you read his axioms. He wants you to live dangerously and shake off the fetters of weakness and mediocrity to reach further and higher.
