Feuerbach, Ludwig (1957). Eliot, George, ур. The Essence of Christianity. New York: Harper & Brothers. стр. 29-30. „Man—this is the mystery of religion—projects his being into objectivity, and then again makes himself an object to this projected image of himself thus converted into a subject; he thinks of himself as an object to himself, but as the object of an object, of another being than himself. Thus here. Man is an object to God.”
