Gao Zi I · 孟子 6A.3
Passage 03
告子曰:「生之謂性。」孟子曰:「生之謂性也,猶白之謂白與?」曰:「然。」「白羽之白也,猶白雪之白;白雪之白,猶白玉之白歟?」曰:「然。」「然則犬之性猶牛之性,牛之性猶人之性歟?」
The philosopher Gao said, 'Life is what we call nature!' Mencius asked him, 'Do you say that by nature you mean life, just as you say that white is white?' 'Yes, I do,' was the reply. Mencius added, 'Is the whiteness of a white feather like that of white snow, and the whiteness of white snow like that of white jade?' Gao again said 'Yes.' 'Very well,' pursued Mencius. 'Is the nature of a dog like the nature of an ox, and the nature of an ox like the nature of a man?'
