This article examines two views of the ethics and efficacy of deception. The Sunzi is famous for its praise of deception and indirect strategy in warfare. This explicit praise of deception distinguishes it from other Militarist texts, which either reject deception or advocate it only as a practical and important strategic tool. The Xunzi rejects deception and indirection in both civil and military contexts. The Sunzi and Xunzi's attitudes toward deception and indirection thus represent opposite poles within Chinese philosophical thought.
