荀子从人性恶的角度构建了自己独特的道德修养论。他一方面从人的自然本性出发,提出人性本恶论;另一方面又从人的社会性出发,提出了“化性起伪”的人性改造论和道德修养论。荀子认为恶在礼仪法度的制约下不仅可以改变,而且必须改变,经过道德修养“涂之人可以为禹”。荀子的道德修养既是一种重学慎思、积善成德的修养功夫,也是一种全粹为美的完美境界追求。 Xunzi built his own unique theory of moral cultivation from the perspective of human nature evil. On the one hand, he put forward the theory of human nature from the nature of human being; on the other hand, from the sociality of mankind, he put forward the theory of human nature transformation and morals accomplishment. Xunzi believes that under the restriction of etiquette, evil can not only be changed, but also must be changed. After moral cultivation, “people who paint can be Yu.” Xunzi’s moral accomplishment is not only a kind of kongfu which focuses on thinking carefully and accumulating good deeds and moral integrity, but also a perfect realm pursuit of being purely beautiful.
