柏拉圖的理型論一直都是探討其知識理論的重心，而學者甚少對他如何看待「知識」的觀念做探討。這篇文章是希望對柏拉圖的「知識的觀念」做一說明。本文是由下列兩部分組成；第一部分將探討柏拉圖的知識的觀念是否類似於當代的知識的觀念，如笛卡兒；第二部分將討論，對柏拉圖而言，知識與理解之間的關係為何。

The theory of Forms has usually occupied scholars' attention in their discussion of Plato's theory of knowledge. However, the problem: What is Plato's view on the notion of knowledge? seems to be seldom talked of. This paper is an attempt to give a brief account of what Plato has in mind when he talks of 'knowledge'. I have divided this paper into two parts, firstly, I would like to discuss the problem: Whether Plato's notion of knowledge is similar to the Cartesian notion of knowledge? Secondly, the relation between knowledge and understanding will be considered.
