“万历朝鲜之役”爆发后,对于是否大举兴兵入援朝鲜,在明朝官员内部引发了一番激烈争论,主援派与反对派展开了激烈交锋。以兵部尚书石星为代表的主援派,除却“字小”之义外,还从“国益”的角度,论述了出兵朝鲜的必要性,而反对派的代表人物兵科给事中许弘纲针对兵部所提出的“中国御倭当于门庭”的意见进行了反驳,表达了对“国益”的深切忧虑。当时的明王朝,并非一片太平盛世。在宁夏,总兵官拜的叛乱,势头正盛,已然消耗了明朝大量的军力、物力。但是主援派和反对派都是从“国益”的角度来进行考量的,无论出兵还是不出兵,都在一定程度上符合明朝的现实国家利益。从中也不难看出,除却对自身“国益”的考量外,争论双方中的“字小”意见和伦理担当,亦无疑构成了万历圣裁的重要促成因素。事实上,朝鲜君臣在向明朝的请师求援中,也在处处巧妙运用这种“事大字小” After the outbreak of the “Battle of Wanli”, there was a heated debate among officials in the Ming Dynasty about whether or not to aggressively build troops into North Korea and the main aid group fiercely confronted the opposition.
