12 It must be said, then, that we have a heart, a heart that coexists with other hearts that help to make it a “Thou”. Since we cannot develop this theme at length, we will take a character from one of Dostoevsky’s novels, Nikolai Stavrogin. Romano Guardini argues that Stavrogin is the very embodiment of evil, because his chief trait is his heartlessness: “Stavrogin has no heart, hence his mind is cold and empty and his body sunken in bestial sloth and sensuality. He has no heart, hence he can draw close to no one and no one can ever truly draw close to him. For only the heart creates intimacy, true closeness between two persons. Only the heart is able to welcome and offer hospitality. Intimacy is the proper activity and the domain of the heart. Stavrogin is always infinitely distant, even from himself, because a man can enter into himself only with the heart, not with the mind. It is not in a man’s power to enter into his own interiority with the mind. Hence, if the heart is not alive, man remains a stranger to himself”.
