Money degrades all the gods of man and converts them into commodities.

The writer must earn money in order to be able to live and to write, but he must by no means live and write for the purpose of making money.

It might otherwise appear paradoxical that money can be replaced by worthless paper; but that the slightest alloying of its metallic content depreciates it.

The circulation of commodities is the original precondition of the circulation of money.

Although gold and silver are not by nature money, money is by nature gold and silver.

Each piece of money is a mere coin, or means of circulation, only so long as it actually circulates.
