Chuang Tzu examines the nature of existence in these dialogues and essays, from the battle to grasp the purpose of life to the search for knowledge. A collection of some of the most absorbing and charming philosophy ever written, "The Tao of Nature" is also about perfection, perception, the value of skills and the truth revealed by complete understanding. "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.
