周必大和张栻在南宋前中期的政治和思想领域均有较大影响。南宋隆兴年间,周必大与张浚同事孝宗,得以认识张栻,此后周必大与张栻交往渐多,频频通过书信交流学术问题,尤其在“知行”问题上,两人论辩颇多。周必大和张栻的“知行”辩论反映了南宋时期旧儒学与新理学之间的歧异互动。 Both Zhou Bida and Zhang Jian had a greater influence in the political and ideological fields in the middle and early Southern Song Dynasty. During the period of Longxing in the Southern Song Dynasty, Zhou Bida and Zhang Jun, the colleague of Xiaozong, got acquainted with Zhang Xun. Since then, Zhou Bida and Zhang Jian have been engaged more frequently, and frequently exchanged academic questions through correspondences, especially on the issue of “knowledge and practice” A lot. The debate between “knowledge and practice” by Zhou Bida and Zhang Jian reflected the differences and interactions between the old Confucianism and neo-Confucianism in the Southern Song Dynasty.
