    二、程朱理学:1、宋代“理学”的产生:(1)含义:所谓“理学”,就是用“理学”一词来指明当时两宋时期所呈现出来的儒学。广义的理学,泛指以讨论天道问题为中心的整个哲学思潮,包括各种不同的学派;狭义的理学,专指程颢、程颐、朱熹为代表的,以“理”为最高范畴的学说,称为“程朱理学”。理学是北宋政治、社会、经济发展的理论表现,是中国古代哲学长期发展的结果,是批判佛、道学说的产物。他们把“理”或“天理”视作哲学的最高范畴,认为理无所不在,不生不灭,不仅是世界的本原,也是社会生活的最高准则。在穷理方法上,程颢“主静”,强调“正心诚意”;程颐“主敬”,强调“格物致知”。在人性论上,二程主张“去人欲,存天理”,并深入阐释这一观点使之更加系统化。二程学说的出现,标志着宋代“理学”思想体系的正式形成。【合作探究】宋代“理学”兴起的社会条件:
