KARL MARX,

“Money is not only an object of the passion for riches; it is the object of that passion. The latter is essentially auri sacra fames. The passion for riches, contrary to that for special kinds of natural wealth or use-values, such as clothing, ornaments, herds, etc., is possible only when universal wealth has been individualized as such in a particular object and can, therefore, be retained in the form of a single commodity. Money appears then no less as an object than as a source of the passion for riches.” A Contribution to the critique of Political Economy (1859)
