“For in order to command well, we should know how to submit; and he who submits with a good grace will some time become worthy of commanding.”
Nam et qui bene imperat, paruerit aliquando necesse est, et qui modeste paret, videtur qui aliquando imperet dignus esse.
Marcus Tullius Cicero book De Legibus
Book III, section 2; translation by Francis Barham
