Literature Reference: 子曰：‘由也，女闻六言六蔽矣乎？’对曰：‘未也。’‘居！吾语女。好仁不好学，其蔽也愚；好知不好学，其蔽也荡；好信不好学，其蔽也贼；好直不好学，其蔽也绞；好勇不好学，其蔽也乱；好刚不好学，其蔽也狂。’——《论语·阳货》 The Master said, ‘You, have you heard the six words and the six faults?’ Yan Hui replied, ‘No.’ ‘Sit down, I will tell you. To love benevolence without loving learning is liable to lead to folly; to love wisdom without loving learning is liable to lead to dissipation; to love sincerity without loving learning is liable to lead to injury; to love straightforwardness without loving learning is liable to lead to rudeness; to love courage without loving learning is liable to lead to insubordination; to love firmness without loving learning is liable to lead to extravagance.’ — From 'The Analects of Confucius,' Chapter Yang Huo.
