Mencius - Book 4, Part 1, Chapter 16

Mencius said, 'The respectful do not despise others. The economical do not plunder others. The prince who treats men with despite and plunders them, is only afraid that they may not prove obedient to him: how can he be regarded as respectful or economical? How can respectfulness and economy be made out of tones of the voice, and a smiling manner?'
