    陸王心學與程朱理學相比有何異同?生 不同點:在理的內涵上不同,程朱理學認為“理”是貫通于宇宙、人倫的客觀存在,是一種普遍的規(guī)律準則;陸王心學認為心即理,是“良知”,認為人心便是世界萬物的本原。方法上也有不同:前者向外追究,“格物致知”;后者向內探求,“發(fā)明本心”以求理,克服私欲、回復良知。生 相同點:都提出了一個宇宙、社會、人生遵循的“理”。師 對。程朱理學是客觀唯心主義,陽明心學是主觀唯心主義。這兩者的分歧是理學范圍內的分歧,其基本思想是一致的。師 宋明理學與漢唐以前的儒學比較,最大的特點在于批判地吸收了佛教哲學的思辨結構和道教的宇宙生成論,將儒家的倫理學說概括升華為哲學基本問題。其實質是把佛、道“養(yǎng)性”“修身”引向儒家的“齊家”“治國”“平天下”,對儒家的綱常道德給予哲學論證,使之神圣化、絕對化、普遍化,以便深入人心,做到人人遵而行之。
