On Liberty
Read this book freeEvery sentence translated, natural audio, one-tap dictionary
John Stuart Mill defends individual freedom against the authority of society and the state. He argues that people should be free to think, speak and act as they wish, provided they harm no one else, and he examines where the limits of that freedom lie. The book is a structured philosophical essay. Its careful arguments and formal vocabulary give advanced learners useful practice with abstract English.
