What Is Man? and Other Essays — Book Summary & Review

Mark Twain’s What Is Man? and Other Essays is a grab bag of philosophy and culture pieces, but the framing question in “What Is Man?” keeps snapping everything back into focus: what counts as human when you strip away manners, religion, and self-congratulation. Twain’s method is to poke at grand definitions until they either collapse or reveal their hidden assumptions. In “What Is Man?” he treats “man” less like a finished category and more like a claim people keep making—then he attacks the flattering parts first, especially the idea that we’re uniquely designed for moral greatness. The essay doesn’t read like a tidy argument; it reads like an intellectual prank with a point, and Twain’s point is that the species label is doing more work than the facts.

A different kind of argument shows up in “As concerns interpreting the Deity,” where Twain’s sarcasm turns into a kind of logic test: if people can interpret God in mutually incompatible ways and still call it certainty, then certainty is not the same thing as truth. Elsewhere, “English as she is taught” and “A simplified alphabet” take aim at the comforting fantasy that our systems are rational simply because they’re traditional. Even when Twain shifts topics—tobacco in “Concerning tobacco,” bicycles in “Taming the bicycle,” or the literary afterlife in “Is Shakespeare dead?”—the same skepticism drives him: human institutions are stubborn, but they’re not sacred.

The essays are also historical and personal in odd flashes, like “The turning-point of my life,” where Twain remembers decisions more than doctrines. Limitation: this collection won’t satisfy readers wanting one sustained philosophical thesis with a consistent conclusion; it’s episodic, and some essays feel like sketches rather than arguments. If you need coherence more than wit, you’ll get impatient with Twain’s bouncing attention.
