In this personal and practical guide to moral self-improvement and living a good life, the second-century philosopher Epictetus tackles questions of freedom and imprisonment, stubbornness and fear, family, friendship and love, and leaves an intriguing document of daily life in the classical world. "Great Ideas": throughout history, some books have changed the world. They have transformed the way we see ourselves - and each other. They have inspired debate, dissent, war and revolution. They have enlightened, outraged, provoked and comforted. They have enriched lives - and destroyed them. Now Penguin brings you the works of the great thinkers, pioneers, radicals and visionaries whose ideas shook civilization and helped make us who we are.
