Laozi
The Daodejing says the Dao is the source and ideal of all existence: it is unseen, very powerful but also very humble, being the root of all things. People have desires and free will. Many act "unnaturally", breaking the natural balance of the Dao. The Daodejing intends to lead students to "return" to their natural state, in harmony with Tao. Taoism views them language as biased and artificial and shows this through paradoxes.
