Nicomachean Ethics

Aristotle tackles one of life's most frustrating puzzles: why do we sometimes do things we know are wrong? He distinguishes between different types of moral failure. True vice is when someone genuinely believes bad behavior is good—like a con artist who thinks cheating is smart business. But incontinence (weakness of will) is when you know what's right but can't stick to it—like knowing you should exercise but binge-watching Netflix instead. Aristotle explains this isn't about lacking knowledge but about how emotions can overwhelm our rational thinking, like being drunk or angry. He argues that anger-driven mistakes are more forgivable than appetite-driven ones because anger at least responds to reason (even if it mishears), while pure appetite just wants what it wants. The chapter also explores different types of pleasures, arguing that not all pleasure is bad—some activities are naturally pleasant and good for us. The key insight is that moral failure often happens not because we don't know better, but because our emotions temporarily hijack our decision-making. Understanding this helps us be more realistic about human nature and more strategic about building better habits. Aristotle suggests that people who struggle with self-control aren't necessarily bad people—they're often more redeemable than those who've convinced themselves that wrong is right.
