The first method for estimating the intelligence of a ruler is to look at the men he has around him. - Niccolò Machiavelli

Any man who tries to be good all the time is bound to come to ruin among the great number who are not good. Hence a prince who wants to keep his authority must learn how not to be good, and use that knowledge, or refrain from using it, as necessity requires.

One should bear in mind that there is nothing more difficult to execute, nor more dubious of success, nor more dangerous to administer, than to introduce new political orders. For the one who introduces them has as his enemies all those who profit from the old order, and he has only lukewarm defenders in all those who might profit from the new order.

I say that every prince must desire to be considered merciful and not cruel. He must, however, take care not to misuse this mercifulness. ... A prince, therefore, must not mind incurring the charge of cruelty for the purpose of keeping his subjects united and confident; for, with a very few examples, he will be more merciful than those who, from excess of tenderness, allow disorders to arise, from whence spring murders and rapine; for these as a rule injure the whole community, while the executions carried out by the prince injure only one individual. And of all princes, it is impossible for a new prince to escape the name of cruel, new states being always full of dangers. ... Nevertheless, he must be cautious in believing and acting, and must not inspire fear of his own accord, and must proceed in a temperate manner with prudence and humanity, so that too much confidence does not render him incautious, and too much diffidence does not render him intolerant. From this arises the question whether it is better to be loved more than feared, or feared more than loved. The reply is, that one ought to be both feared and loved, but as it is difficult for the two to go together, it is much safer to be feared than loved, if one of the two has to be wanting. For it may be said of men in general that they are ungrateful, voluble, dissemblers, anxious to avoid danger, and covetous of gain; as long as you benefit them, they are entirely yours; they offer you their blood, their goods, their life, and their children, as I have before said, when the necessity is remote; but when it approaches, they revolt. And the prince who has relied solely on their words, without making other preparations, is ruined, for the friendship which is gained by purchase and not through grandeur and nobility of spirit is merited but is not secured, and at times is not to be had. And men have less scruple in offending one who makes himself loved than one who makes himself feared; for love is held by a chain of obligation which, men being selfish, is broken whenever it serves their purpose; but fear is maintained by a dread of punishment which never fails.
