Zen k\u014dans serve a didactic function within the institution of Buddhist schools, with teachers using them to help their pupils reach enlightenment. In this paper, I suggest that Platonic dialogues function similarly to Zen k\u014dans in their inducement of aporia. Thus, reading and understanding the role Zen k\u014dans are intended to play within Buddhist schools illuminates the role of aporia in Western philosophy. Using Plato\u2019s Seventh Letter as a guide for reading Platonic dialogues, I analyze the form of Platonic dialogues generally and highlight how the commentarial traditions engage dialectically with the original texts. Second, I compare and contrast the form and function of Zen k\u014dans and Platonic dialogues, taking the authority of the master and philosopher and their orientation towards truth as the driving force in both. I focus on a k\u014dan written, ostensibly, by Qingyuan Weixin in the 13th century and Plato\u2019s Republic. I then show how, when stripped of content, the engagement with Zen k\u014dans can be understood in terms of the catuskoti. I suggest how this might also be the case for Platonic dialogues.
