英國經濟學家（1842－1924） 来自维基百科，自由的百科全书
阿尔弗雷德·马歇尔（英语：Alfred Marshall，1842年7月26日—1924年7月13日），英国新古典学派经济学家。其主要著作《经济学原理》自1890年出版，至1920年共更新8版，不但是当时英国最通行的经济学参考书，其中有关供给需求、边际效益与生产成本的重新整理更奠定其经济学创始人之一的地位。
在一封寄给统计学家、经济学家亚瑟·里昂·鲍利的信里，他写道:
“(1)把数学当作速记语言，而非探讨的工具。(2)用这个方法一直到把想法完全记下为止。(3)将之译为英文。(4)举例说明为何这些想法在真实生活里重要。(5)把数学烧掉。(6)如果你做不到(4)，就把(3)烧掉。我经常做这最后一点。”
[I had] a growing feeling in the later years of my work at the subject that a good mathematical theorem dealing with economic hypotheses was very unlikely to be good economics: and I went more and more on the rules - (1) Use mathematics as a shorthand language, rather than an engine of inquiry. (2) Keep to them till you have done. (3) Translate into English. (4) Then illustrate by examples that are important in real life. (5) Burn the mathematics. (6) If you can't succeed in (4), burn (3). This last I did often.
