当代中国儒家传统的复兴展现出从探讨心性哲学到关注政治与社会的思想转向。以"制度形态—目标指向"作为维度,当代中国的儒教复兴实践可类型化为政治实践型、传统教化型、公民宗教型和生活教化型四种理想类型。"制度形态"的差异凸显了... 详细信息

当代中国儒家传统的复兴展现出从探讨心性哲学到关注政治与社会的思想转向。以"制度形态—目标指向"作为维度,当代中国的儒教复兴实践可类型化为政治实践型、传统教化型、公民宗教型和生活教化型四种理想类型。"制度形态"的差异凸显了对于儒教的制度焦虑与反思,"目标指向"的分野体现出当代儒教实践的不同行动抱负,其一以贯之的内在逻辑是儒教制度性和分散性的双重特征:大可化入政治制度,兼济天下;小可教化社会公众,独善其身。儒教的建构与表达受到权力关系的形塑,在儒学与儒教的分化与合流之间,深切影响着儒教复兴运动的兴衰成败。
