" Man distinguishes himself from Nature. This distinction of his is his God: the distinguishing of God from Nature is nothing else than the distinguishing of man from Nature. … [S]peculations and controversies concerning the personality or impersonality of God are therefore fruitless, idle, uncritical … ; … they in truth speculate only concerning themselves, only in the interest of their own instinct of self-preservation[.] "

― Ludwig Feuerbach , The Essence of Christianity
