“I marvelled still more that he should be dead and I his other self living still. Rightly has a friend been called “the half of my soul.” For I thought of my soul and his soul as one soul in two bodies; and my life was a horror to me because I would not live halved. And it may be that I feared to die lest thereby he should die wholly whom I had loved so deeply.”
— St. Augustine, Confessions IV.VI, tr. Sheed
