Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that. Hate multiplies hate, violence multiplies violence, and toughness multiplies toughness in a descending spiral of destruction.
- Martin Luther King Jr
The simple, absolute and immutable mysteries of the divine Truth are hidden in secret. For this darkness, though of deepest obscurity, is yet radiantly clear; and, though beyond touch and sight, it more than fills our unseeing minds with splendors of transcendent beauty. And we behold that darkness beyond being, concealed under all natural light.
- Dionysius the Aeopagite
But why does truth engender hatred? Why does your servant meet with hostility when he preaches the truth, although men love happiness, which is simply the enjoyment of truth? It can only be that man’s love of truth is such that when he loves something which is not the truth, he pretends to himself that what he loves it the truth, and because he hates to be proved wrong, he will not allow himself to be convinced that he is deceiving himself. So he hates the real truth for the sake of what he takes to his heart in its place. Men love the truth when it bathes them in its light: they hate it when it proves them wrong (emphasis added).
- Saint Augustine, Confessions
