作为宋代最具“近世精神”的政治观念之一，异论相搅较少获得史学界留意，且多被解读为分权御臣的帝王术和党争祸乱之源。从观念构设和制度运施看，异论相搅可视为一种具有协商性质的政治安排，鼓励多元意见表达、协商，藉由多元熟议建构共识、“共定国是”。宋代形成了一套由理性规范、言制体系担保，“公论”与舆论桥接，“异论”与“致一”平衡的政治协商框架，推动异论相搅通往共识和秩序，进而增进权力正当性、合理性与有效性。此一安排历经两宋三百余年操运、检验，虽有价值预设和制度实践上的历史囿限，仍可为构建现代协商政治体系提供厚实的思想资源。

As the political conception mostly tinted with “early modern spirit” in the Song Dynasty, “holding debates for the discussion of different views” has gained few emphases from historians and has been interpreted as the Monarchical Politics of managing officials by distributing power among them, and as the source of and party strife and chaos. In fact, from the perspective of concept construction and system operation and maintenance, “holding debates for the discussion of different views” can be regarded as a political arrangement of a consultative nature which encourages the expression, competition, and consultation of diversified opinions, reaches consensus through pluralistic deliberative discussions, and “holding discussions concerning national policies and principles”. The Song Dynasty formed the consultative politics framework guaranteed by rational norms and The Official Communication System, connecting “public comments” with public opinion, and balancing “different views” and “reaching consensus” to promote the establishment of consensus and order through the practice of “holding debates for the discussion of different views” to enhance the legitimacy, rationality and effectiveness of power. This politics has been operated and tested by The Northern and Southern Song Dynasties for more than three hundred years and can provide a solid ideological resource for the construction of a modern consultative politics system despite its historical limitations in its value presuppositions and system implementation.
