《陽貨》 Passage 17.8
子曰：「由也，女聞六言六蔽矣乎？」對曰：「未也。」「居！吾語女。好仁不好學，其蔽也愚；好知不好學，其蔽也蕩；好信不好學，其蔽也賊；好直不好學，其蔽也絞；好勇不好學，其蔽也亂；好剛不好學，其蔽也狂。」

There is the love of knowing without the love of learning; — the beclouding here leads to dissipation of mind. There is the love of being sincere without the love of learning; — the beclouding here leads to an injurious disregard of consequences. There is the love of straightforwardness without the love of learning; — the beclouding here leads to rudeness. There is the love of boldness without the love of learning; — the beclouding here leads to insubordination.
