Paul Tillich

"Buber and Tillich each took similar paths toward their common destination of religious socialism. Both had been influenced early in their careers by the 19th century German philosopher Nietzsche's rejection of bourgeois culture in his classic book, Thus Spoke Zarathustra, and were further influenced by Karl Marx's doctrine of human self-estrangement and objectification in capitalist society while rejecting his anti-religious bias. Moreover, Buber and Tillich, along with all religious socialists, rejected the Marxist “revolutionary dictatorship” of the proletariat. This would represent the extreme of heteronomy for Tillich and the political manifestation of the I-it relationship expressed by Buber that is based on human instrumentalism. … Tillich initially promoted an "idealistic anarchism" in the sense that he envisioned a theonomous culture arising from "communities themselves and their spiritual substance" instead of being promoted by the state. They would eventually part ways to some extent, with Buber continuing to promote a "federalistic communal socialism" yet not rejecting the political component of social life, while Tillich promoted the possibility of a central government that is not absolute in a theonomous society."
