Evil is opposition to life. It is that which opposes the life force. It has, in short, to do with killing. . . . Evil is also that which kills the spirit. . . . Evil is that force, residing either inside or outside of human beings, that seeks to kill life or liveliness. And goodness is its opposite. Goodness is that which promotes life and liveliness.
— M. Scott Peck, Sins of the Spirit, Blessings of the Flesh by Matthew Fox
