Lao Tzu, a wise man, was born and died somewhere around the 6th century BC, and is considered the founder of Taoism and its first philosopher. He is considered the author of Daodejing, also known as Tao Te Ching. Daodejing is based on dao as a cosmological and philosophical foundation, a first original principle that governs all existence. It is its properties, and the consequences thereof, the book explains. Dao is a world order that people do best to submit to, so as not to create problems. The book states that this is best done through wu wei, non-action. According to Daodejing, the world is so ingeniously arranged that most things resolve themselves if people avoid acting. Based on this foundation, the book develops an ideal of peace and a humility towards the order of nature, which calls for unpretentiousness and humility.
