“The economic laws must not be sought & cannot be found on the properly economic field. It is on the vital field, then, that the laws of economics must be discovered & studied, & the data of economics interpreted. To recognize this will be to humanize economics.”
Philip Wicksteed. “The Common Sense of Political Economy, & Selected Papers & Reviews on Economic Theory. London,George Routledge & Sons, Ltd., 1933. Original edition: London, Macmillan & Company, Ltd., 1910.
