Gustav Cassel

"Economics is in high degree a pedagogical discipline, and an economist must be in close touch with popular psychology in order to know what ought to be said at any particular moment."

"If my theoretical studies have contained any subjective value judgment, then this has amounted at most to a preference for freedom and progress rather than state control of the economy and distribution of such scanty prosperity as may be available for distribution at a given moment. I have wanted to make it clear that this preference is a great common interest of all parties, both in the management of the world economy and in every individual nation. Such a position may be attacked, but it cannot be denominated as party-politics in the ordinary sense."
