Spenglerism

Spenglerism is a conservative philosophy that rejected both liberalism and marxism as Spengler had considered them to be both based on the english spirit which was opposed to the german spirit. Spengler advocated that both german conservatives and german (non-communist) socialist must cooperate against the weimar republic. Spengler also advocated for a new system which can be summarized as a socialist-corporatist nationalist-militarist state under a authoritarian Prussian monarchy.

Cultures/Civilizations
Spenglerism using the two terms in a specific manner, loading them with particular values. For him, Civilization is what a Culture becomes once its creative impulses wane and become overwhelmed by critical impulses. Culture is the becoming, Civilization is the thing become. Rousseau, Socrates, and Buddha each mark the point where their Cultures transformed into Civilization. They each buried centuries of spiritual depth by presenting the world in rational terms—the intellect comes to rule once the soul has abdicated.

Spenglerism classifies eight Hochkulturen or high cultures have existed: Babylonian, Egyptiac, Indic, Sinic, Mesoamerican (Mayan/Aztec), Apollonian or Classical (Greek/Roman), Magian or Arabian, and Faustian or Western (European).

Prussian Socialism
SPengler rejected both marxism and capitalism which he saw as both being based on the English spirit which was based on money and was antithetical to the German spirit which was based on money and instead promoted a form of socialism based on the German spirit.
