In The Shadow of Mount Sinai

In this short book, Peter Sloterdijk clarifies his views on religion and its role in pre-modern and modern societies. He begins by returning to the Mount Sinai episode in the Book of Exodus, where he identifies the emergence of what he calls the Sinai Schema.

At the core of monotheism is the logic of belonging to a community of confession, of being a true believer—this is what Sloterdijk calls the Sinai Schema. To be a member of a people means that you submit to the beliefs of the community just as you submit to its language. Monotheism is predicated on the logic of one God who demands your utmost loyalty. Hence, at the core of monotheism is also the fear of apotheosis, of heresy, of heterodoxy. Monotheism is associated, first and foremost, with a certain kind of internal violence—namely, a violence against those who violate their membership through a break in loyalty and trust.

On the basis of this analysis of the inner logic of monotheism, Sloterdijk retraces its historical legacy and shows how this account enables us to understand why we react so nervously today to all forms of fundamentalism—whether that of radical Islamists, the Catholic Pius Brotherhood, or evangelical sects in the USA.
