The young Moeller van den Bruck believed German literature and philosophy, particularly the works of Nietzsche, to be a more vital education.

His essay Der Preußische Stil ("The Prussian Style") in which he celebrated the essence of Prussia as "the will to the state" appeared in 1916 and marked his embrace of nationalism.

It showed him as an opponent of parliamentary democracy and liberalism, and it exerted a strong influence on the Jungkonservativen ("young conservative movement").

Moeller van den Bruck was the joint founder of the "June Club" (Juniklub), which sought to influence young conservatives in the fight against the Treaty of Versailles.

In the same book, Moeller van den Bruck advocated an expressly anti-Western and anti-imperialist philosophy of the state (Staatstheorie), which attempted to bridge the gap between nationalism and concepts of social justice.
