在哲學家的眼中，藝術家們所創造的繪畫世界就是他們構思法國思想的「催化劑」，而在今日，我們可以看見這種催化劑的作用出現在阿蘭．巴迪歐（Alain Badiou）的哲學思想以及皮耶．蘇拉吉（Pierre Soulages）的繪畫之間。對巴迪歐來說，蘇拉吉的「在黑之外」（l’Outrenoir）是一種通往「無限」的「真理作品」。透過分析蘇拉吉的「在黑之外」，我們可以思索巴迪歐所發展的哲學思想，尤其是關於「真理作品」所通往的「無限」概念。因此，本文主要在闡明蘇拉吉的「在黑之外」作為真理作品如何通往「無限」以及「在黑之外」作為這種「真理作品」之價值。

In the eyes of French philosophers, the world of painting created by artists is the “catalyst” for the development of their ideas. Today, we can see that the effect of this catalyst is exemplified by the relationship between Alain Badiou’s philosophical thoughts and Pierre Soulages’ paintings. For Badiou, Soulages’s “Outrenoir” is a “work of truth” accessing “infinity,” By analyzing Soulages’ “Outrenoir”, we can reflect on the philosophical thought that Badiou develops, in particular on Badiousian concept of “infinity” which the “work of truth” accesses. Therefore, this article analyses how Soulages’ “Outrenoir” as a “work of truth” accesses “infinity” and the value of “Outrenoir”as this “work of truth”.
