本文以柏拉圖《巴門尼德篇》第一部分為研究對象，分析其中理念論所面臨的六個詰難。在此基礎上得出結論：柏拉圖的批評並非要取消或者消解理念論，而是要展示早中期理念論所面臨的困難。不僅如此，柏拉圖在批評中已經隱含地給出了解決問題的方案，本文將徹底澄清這一點，給六個詰難一個一以貫之的解答。

In this paper, I take the first part of Plato’s dialogue Parmenides as subject matter, analysing the six aporiai which Plato’s theory of idea probably leads to. Based on the detailed text analysis, I draw a conclusion that Plato’s criticism does not aim to abolish his theory of idea, but Plato is inclined to illuminate the problems that arise from his early and mid-term dialogues. In addition, I argue that Plato implies as well as gives solutions to the problems mentioned in his criticism. In closing, I provide a consistent solution to all of the six aporiai.
