材料一：为他们的政权合法性寻找某种原则，对于他们是至关重要的。……汉朝皇帝的高招是，延揽始终坚持封建制度的学派来支持中央集权的国家……他们最大成就是，使这个从未亲身经历封建时代的新文人阶层相信，孔子的学说能够应用于新的政治体制……中央集权国家的理念逐渐与这个文人阶层和儒家信徒紧密结合起来。这个文人阶层原来捍卫的是旧封建制度，但是在此之后，他们一直反对任何分裂活动。

——菲茨杰拉德《中国简明文化史》

材料二：周道衰，孔子没，火于秦，黄老于汉，佛于晋、魏、梁、隋之间。其言道德仁义者……不入于老，则归于佛……后之人其欲闻仁义道德之说，孰从而听之？老者曰：“孔子，吾师之弟子也。”佛者曰：“孔子，吾师之弟子也。”为孔子者，习闻其说 ，乐其诞而自小也，亦曰“吾师亦尝师之云尔”。

——韩愈《原道》

材料三：然以释氏所见，较之吾儒，彼不可谓无所见，但却只是从外面见得个影子，不曾见得里许真实道理，所以见处则尽高明脱洒，而用处七颠八倒，无有是处。

——朱熹《答陈卫道》
