 Among early works, the Daoist tradition usually places the Zhuangzi immediately after the Daode jing. A third text, the Liezi, has fallen into a sort of limbo, especially after A.C. Graham demonstrated that parts of the received text are not authentic and date from not earlier than the 2nd century CE (instead of the 4th century BCE, as was supposed earlier; Graham 1961). Recently, however, there have been efforts to rehabilitate this work (Barrett 2011), also motivated by the fact that it appears to contain lost fragments of the Zhuangzi.
