The Tao Te Ching or Dào Dé Jīng, (traditional Chinese: 道德經; simplified Chinese: 道德经; lit. 'Classic of the Way and its Virtue') often Laozi in Chinese and scholarship, is an ancient Chinese classic text, becoming a foundational work of Taoism. It is traditionally credited to the sage Laozi, though with some several early versions recovered, the texts' authorship and dates of composition and compilation are debated. The oldest excavated portion dates to the late 4th century BCE. While tradition places Laozi earlier, modern versions of the text could more conservatively be estimated to date back to the late Warring States period (475 – 221 BCE), not having been recovered that early.
The Tao Te Ching is central to both philosophical and religious Taoism, and has been highly influential on Chinese philosophy and religious practice in general. It is generally taken as preceding the Zhuangzi, the other core Taoist text. Terminology originating within the text has been reinterpreted and elaborated upon by Legalist thinkers, Confucianists, and particularly Chinese Buddhists, introduced to China significantly after the initial solidification of Taoist thought. One of the most translated texts in world literature, the text is well known in the West.
