“Plato rightly taught that virtue is one. You cannot be kind unless you have all the other virtues. If, being cowardly, conceited, and slothful, you have never yet done a fellow creature great mischief, that is only because your neighbour's welfare has not yet happened to conflict with your safety, self-approval, or ease. Every vice leads to cruelty.”
― C.S. Lewis, The Problem of Pain
