    人教版高中历史必修3宋明理学说课稿3篇

    陆王心学与程朱理学相比有何异同?生 不同点:在理的内涵上不同,程朱理学认为“理”是贯通于宇宙、人伦的客观存在,是一种普遍的规律准则;陆王心学认为心即理,是“良知”,认为人心便是世界万物的本原。方法上也有不同:前者向外追究,“格物致知”;后者向内探求,“发明本心”以求理,克服私欲、回复良知。生 相同点:都提出了一个宇宙、社会、人生遵循的“理”。师 对。程朱理学是客观唯心主义,阳明心学是主观唯心主义。这两者的分歧是理学范围内的分歧,其基本思想是一致的。师 宋明理学与汉唐以前的儒学比较,最大的特点在于批判地吸收了佛教哲学的思辨结构和道教的宇宙生成论,将儒家的伦理学说概括升华为哲学基本问题。其实质是把佛、道“养性”“修身”引向儒家的“齐家”“治国”“平天下”,对儒家的纲常道德给予哲学论证,使之神圣化、绝对化、普遍化,以便深入人心,做到人人遵而行之。
