Lao Tzu, author of Tao Te Ching, was a philosopher and poet of ancient China. As founder of philosophical Taoism, he's a legendary figure dated back to the 6th Century BCE and supposedly a contemporary of Confucius. Throughout history, Laozi's work has been embraced by various anti-authoritarian movements.

“When the people of the world all know beauty as beauty, There arises the recognition of ugliness. When they all know the good as good, There arises the recognition of evil. Therefore: Being and non-being produce each other; Difficult and easy complete each other; Long and short contrast each other; high and low distinguish each other; Sound and voice harmonize with each other; Front and back follow each other. Therefore the sage manages affairs without action (wu-wei) And spreads doctrines without words.“

-Lao Tzu
