There are other things that classify people as knaves. Jealous of your colleague’s success? You’re a knave. (Remember that famous knave Iago, warning the smart creative Othello to “beware, my lord, of jealousy. It is the green-eye’d monster, which doth mock the meat it feeds on.”46) Taking credit for someone else’s work? Knave. Selling a customer something she doesn’t need or won’t benefit from? Knave. Blowing up a Lean Cuisine in the company microwave and not cleaning it up? Knave. Tagging the wall of a nave? Knave.
