馬里旦和吉爾松是同一個時代的人，他們來自同一個國家，分享著相同的信仰以及哲學傳統，然而兩人對於藝術的看法在某些點上卻是完全對立的，其差異產生的原因，值得我們仔細地探討。本文的主要目的，是希望從美與真、藝術與知識之間的論辯入手，逐步勾勒出馬里旦與吉爾松這兩位優秀的天主教哲學家在思考美術問題上所顯現的差異。並進一步在理解其差異後，體認到兩人關於美術的不同看法，與其說是某種對立或不相容的衝突，不如說是他們從不同的角度切入美術問題而揭露出關於美、關於美術所展現的不同面向與意義。

Jacques Maritain and Etienne Gilson, despise the fact that they came from the same country, shared the same religious beliefs and belonged to the same philosophical school (Neo-Thomism), expressed opposite opinions towards certain points in fine arts. It is worth the effort to find out why and how this controversy appeared because their views help us to see a deeper meaning of art. This paper starts with illustrating Maritain and Gilson's respective views on fine arts.Through discerning the boundary between beauty and truth, art and knowledge, this paper presents the key points of their arguments. After realizing why and how the conflict arose, this paper offers a different view on truth concerning art, and also shows that the disagreements between Maritain and Gilson may not be treated as an uncompromising conflict; rather, these two philosophers simply dealt with fine arts from different perspectives and thereby demonstrated respective aspects and meaning about art and fine arts.
