Northwestern University西北大学校训是:Whatsoever Things Are True。即:凡事求真。
这句校训是摘自于新约圣经的腓利比书第四章8节。全句是“Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things”
中文意思是:“我还有未尽的话.凡是真实的、可敬的、公义的、清洁的、可爱的、有美名的.若有甚么德行、若有甚么称赞、这些事你们都要思念。” 腓利比书是在公元一世纪,在罗马帝国殖民统治时期,圣使徒保罗写给腓利比教会基督徒的勉励。
