Karl Marx

"Every opinion based on scientific criticism I welcome. As to prejudices of so-called public opinion, to which I have never made concessions, now as aforetime the maxim of the great Florentine is mine:

“Segui il tuo corso, e lascia dir le genti.” Follow your own course, and let people talk – paraphrased from Dante" Karl Marx London, July 25, 1867.

"From the viewpoint of pure economic theory, Karl Marx can be regarded as a minor post-Ricardian". Paul Samuelson,The American Economic Review, March 1962, pp. 12-15
