The Tao Te Ching, also Dao De Jing ( Traditional Chinese: 道德經 ), roughly translatable as The Book of the Way and its Virtue (see below), is a Chinese classic text. According to tradition, it was written around 6th century BCE by the Taoist sage Laozi (or Lao Tzu, "Old Master"), a record-keeper at the Zhou Dynasty court. The text's authorship and date of composition or compilation are still debated.
The Tao Te Ching is fundamental to the Taoist school (Daojia 道家) of Chinese philosophy and strongly influenced other schools, such as Legalism and Neo-Confucianism. This ancient book is also central in Chinese religion, not only for Taoism (Daojiao 道教) but Chinese Buddhism, which when first introduced into China was largely interpreted through the use of Taoist words and concepts. Many Chinese artists, including poets, painters, calligraphers, and even gardeners have used the Tao Te Ching as a source of inspiration. Its influence has also spread widely outside East Asia, aided by hundreds of translations into Western languages.
The Wade-Giles romanization Tao Te Ching dates back to early English transliterations in the late 19th century, and some people continue using it. The pinyin romanization Daodejing originated in the late 20th century, and this romanization is becoming increasingly popular. See discussion at Daoism-Taoism romanization issue.
