[M]oral advance carries with it intuitions of unity which are increasingly less misleading. Courage, which seemed at first to be something on its own, a sort of specialised daring of spirit, is now seen to be a particular operation of wisdom and love.[…] Freedom, we find out, is not an inconsequential chucking of one’s weight about, it is the disciplined overcoming of self. Humility is not a peculiar habit of self-effacement, rather like having an inaudible voice, it is self-less respect for reality and one of the most difficult and central of all virtues.
