所有日月星辰，盡皆虛空～叔本華

他將發現，人我之別，在壞蛋看來如此巨大，其實只是無常虛幻。他將不假思索即能明白，他之存在己身，於他人亦然，一種生存意志，構成萬事萬物之內在本質。此於動物亦然，整個大自然都是這樣。因此，他將甚至不會給一隻動物帶來痛苦…對那些能否定己身意志者而言，這屬於我們的世界將如此真實，所有日月星辰，盡皆虛空。～叔本華，《世界做為一種意志與意念》（1883），第一冊481及532頁。

He sees that the distinction between himself and others, which to the bad man is so great a gulf, only belongs to a fleeting and illusive phenomenon. He recognizes directly and without reasoning that the in-itself of his own manifestation is also that of others, the will to live, which constitutes the inner nature of everything and lives in all; indeed that this applies also to the brutes and the whole of nature, and therefore he will not cause suffering even to a brute…to those in whom the will has turned and denied itself, this our world which is so real, with all its suns and milky ways—is nothing.—Arthur Schopenhauer，《The World as Will and As Idea》（1883），pp. 481, 532.
