And here be it noted that if you would be obeyed you must know how to command, and that they alone have this knowledge who have measured their power to enforce, with the willingness of others to yield obedience; and who issue their orders when they find these conditions combining, but, otherwise, abstain. Wherefore, a wise man was wont to say that to hold a republic by force, there must be a proportion between him who uses the force and him against whom it is used; and that while this proportion obtains the force will operate; but that when he who suffers is stronger than he who uses the force, we may expect to see it brought to an end at any moment. But returning to the matter in hand, I say that to command things hard of execution, requires hardness in him who gives the command, and that a man of this temper and who issues such commands, cannot look to enforce them by gentleness. He who is not of such a temper must be careful not to impose tasks of extraordinary difficulty, but may use his natural gentleness in imposing such as are ordinary. For common punishments are not imputed to the prince, but to the laws and ordinances which he has to administer. We must believe, therefore, that Manlius was constrained to act with severity by the unusual character of the commands which his natural disposition prompted him to issue. Such commands are useful in a republic, as restoring its ordinances to their original efficacy and excellence. And were a republic, as I have before observed, fortunate enough to come frequently under the influence of men who, by their example, reinforce its laws, and not only retard its progress towards corruption, but bring it back to its first perfection, it might endure for ever.
