「(1)把數學當作速記語言,而非探討的工具。(2)用這個方法一直到把想法完全記下為止。(3)將之譯為英文。(4)舉例說明為何這些想法在真實生活裡重要。(5)把數學燒掉。(6)如果你做不到(4),就把(3)燒掉。我經常做這最後一點。」 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. — A History of Economic Theory and Method: Sixth Edition,
