王弼是以老莊畜學解易的創始人，魏晉易學義理學派的代表，於魏晉以畜學為主的時代中，理論呈現在於注老和注易，而注易的特色在於掃象，在當時是種很大的革新和創舉。本文從王弼注易掃象的觀點，解釋其「無」與「自然」的旨要，並找出老子注易和聖人體無的關聯性，以理解理弼學說中之一致性。

　　　　　Wang Bi started the metaphysical interpretations of Yi Jing from the perspective of Lao-Zhuang and represented the doctrine of Yi in the Wei and Jin Period. The prominently metaphysical philosophy of the Wei and Jin Period is presented in the annotations of Lao zi and Yi Jing, and the defining feature of the annotations of Yi Jing is the breakaway with the images, which is an important and unforeseen revolutionary act at that time. this paper is intended to explain Wang Bi's ideas about "Wu" and "nature" from the approach of breakaway with images and identify the consistency of Wang's doctrine by finding the link between Lao zi's annotations of Yi and the idea of "understanding sages' Wu."
