In creating the decemvirate, therefore, both the senate and the people made grave mistakes. For although, as already explained, when speaking of the dictatorship, it is those magistrates who make themselves, and not those made by the votes of the people, that are hurtful to freedom; nevertheless the people, in creating magistrates ought to take such precautions as will make it difficult for these to become bad. But the Romans when they ought to have set a check on the decemvirs in order to keep them good, dispensed with it, making them the sole magistrates of Rome, and setting aside all others; and this from the excessive desire of the senate to get rid of the tribunes, and of the commons to get rid of the consuls; by which objects both were so blinded as to fall into all the disorders which ensued. For, as King Ferrando was wont to say, men often behave like certain of the smaller birds, which are so intent on the prey to which nature incites them, that they discern not the eagle hovering overhead for their destruction. In this Discourse then the mistakes made by the Roman people in their efforts to preserve their freedom and the mistakes made by Appius in his endeavour to obtain the tyranny, have, as I proposed at the outset, been plainly shown. CHAPTER XLI.—_That it is unwise to pass at a bound from leniency to severity, or to a haughty bearing from a humble._ Among the crafty devices used by Appius to aid him in maintaining his authority, this, of suddenly passing from one character to the other extreme, was of no small prejudice to him. For his fraud in pretending to the commons to be well disposed towards them, was happily contrived; as were also the means he took to bring about the reappointment of the decemvirate. Most skilful, too, was his audacity in nominating himself contrary to the expectation of the nobles, and in proposing colleagues on whom he could depend to carry out his ends. But, as I have said already, it was not happily contrived that, after doing all this, he should suddenly turn round, and from being the friend, reveal himself the enemy of the people; haughty instead of humane; cruel instead of kindly; and make this change so rapidly as to leave himself no shadow of excuse, but compel all to recognize the doubleness of his nature. For he who has once seemed good, should he afterwards choose, for his own ends, to become bad, ought to change by slow degrees, and as opportunity serves; so that before his altered nature strip him of old favour, he may have gained for himself an equal share of new, and thus his influence suffer no diminution. For otherwise, being at once unmasked and friendless, he is undone: CHAPTER XLII.—_How easily Men become corrupted._
