阅读下列材料:材料一:季康子问政于孔子曰:“如杀吾道,以就有道,何如?”孔子对曰:“子为政,焉用杀?子欲善而民善矣,君子之德风,小人之德草,草上之风,必偃。”――《论语·为政》

材料二:(董)仲舒复对曰:“……春秋大一统者,天地之常经,古今之通谊也。今师异道,人异论,百家珠(异)方,指意不同,是以上亡(无)以持一统。法制数变,下不知所守。臣愚以为诸(那些)不在六艺(六经)之科、孔子之术者,皆绝其道,勿使并进。邪避之说灭息,然后统纪可一(一致)而法度可明,民知所从矣。”

――《汉书·董仲舒传》

材料三:至论天下之理,则要妙精微,各有攸当。亘古亘今,不可移易,唯古之圣人为能尽之。而其所行所言,无不可为天下后世不易之大法。――(南宋)朱熹《行宫便殿奏札》

材料四:前三代,吾无论矣;后三代,汉、唐、宋是也。中间千百余年而独无是非者,岂其人无是非哉?咸以孔子之是非为是非,故未尝有是非耳。――(明)李贽《藏书》

请回答:

根据材料三、四指出李贽的观点同朱熹的观点有何不同。这种不同主要说明了什么问题?
