What is Mammonism?
 Mammonism is the sinister, invisible, mysterious reign of the great international
 money-powers. Mammonism is however also a mindset; it is the worship of these
 money-powers on the part of all those who are infected with the Mammonistic
 poison. Mammonism is the unlimited hypertrophy of the -- in itself healthy --
 human drive for acquisition. Mammonism is the lust for money grown into a
 madness, which knows no higher goal than to pile money on top of money, which
 seeks with unequaled brutality to coerce all forces of the world into its service,
 and must lead to the economic enslavement, to the exploitation of the work
potential of all peoples of the world. Mammonism is the mindset that has led to a
 decline of all moral concepts. Mammonism considered as a worldwide
 phenomenon is to be equated with brutal, ruthless egoism in man. Mammonism is
 the spirit of greed, of boundless desire to rule, of the mentality entirely focused on
 seizing the goods and treasures of the world; it is at its core the religion of the
 purely worldly-oriented human type.
 Mammonism is the direct opposite of socialism. Socialism, conceived as the
 highest moral idea, as the idea that man is not in the world only for himself alone,
 that every man has duties toward the community, toward all humanity, and that
 he is not only responsible for the momentary wellbeing of his family, of the
 members of his tribe, of his folk, but that he also has unshakable moral obligations
 toward the future of his children and his folk.
 More concretely, we must see Mammonism as the conscious collusion of the
 power-hungry big capitalists of all peoples. Noteworthy in this has always been the
 hidden arrival of Mammonism.
 The big tycoons lurk indeed as the ultimate driving force behind world
encompassing Anglo-American imperialism; nothing else. The great money-powers
 indeed financed the terrifying mass-homicides of the World War. The great
 money-powers have indeed, as owners of all great newspapers, woven the world
 into a web of lies. They have with satisfaction whipped up all lower passions, have
 diligently fostered the growth of present tendencies, and have through clever
 press-propaganda brought French revanchism to a boil. They carefully nurtured the
 Pan-Slavic idea, the Serbian conceit of being a great power, and the need of these
 states for money, to the point that the world conflagration must ignite.
 Even among us in Germany the spirit of Mammonism that wanted to know only
 more export-figures, national wealth, expansion, big bank projects, and
 international finance deals, led to a rout of public morality, to the decline of our
 ruling circle into materialism and hedonism, to a superficiality in our national life,
 all factors that share blame for the terrifying collapse.
