弗雷德里克·巴斯夏:经济诡辩·摘录 112

弗雷德里克·巴斯夏《经济诡辩》· Economic Sophisms · 投资

We are constantly told that our principles do not hold good, except in theory. But tell me, gentlemen, if you regard the books of merchants as holding good in practice? It appears to me that if there is anything in the world which should have practical authority, when the question regards profit and loss, it is commercial accounts. Have all the merchants in the world come to an understanding for centuries to keep their books in such a way as to represent profits as losses, and losses as profits? It may be so, but I would much rather come to the conclusion that M. Lestiboudois is a bad economist.

白话

巴斯夏反驳“原则只在理论上成立”的说法:商人的账簿就是实践,记录盈亏。如果全世界商人几百年来都合谋把盈利记成亏损、亏损记成盈利,那或许可能;但更合理的结论是莱斯蒂布多瓦这个经济学家错了。核心是:实践数据(如商业账目)比抽象理论更有说服力,不能以“理论不实用”为借口忽视事实。做法是检查实际账目和证据,而非空谈理论。

上下文

巴斯夏在《经济诡辩》中常用商人账簿作例子,说明贸易差额说的荒谬:若进口多于出口是损失,商人为何还这样做?

今日一问

我是否也曾用“理论上对但实践上行不通”来搪塞,而没有去查看实际数据?
