Excellent flatterers welcome attentive audiences; mighty potentates enjoy public praise. In the most pleasing situation, a flatterer would genuinely admire the flatteree, please that person, please other present company, be pleased to stagger rivals, and get something out of it: applause, promotion, a favor, reciprocal praise. Flattery is as social as a banquet.
