Niccolò Machiavelli, The Prince

"For that reason, let a prince have the credit of conquering and holding his state, the means will always be considered honest, and he will be praised by everybody because the vulgar are always taken by what a thing seems to be and by what comes of it; and in the world there are only the vulgar, for the few find a place there only when the many have no ground to rest on."

"But confining myself more to the particular, I say that a prince may be seen happy to-day and ruined to-morrow without having shown any change of disposition or character. This, I believe, arises firstly from causes that have already been discussed at length, namely, that the prince who relies entirely upon fortune is lost when it changes. I believe also that he will be successful who directs his actions according to the spirit of the times, and that he whose actions do not accord with the times will not be successful. Because men are seen, in affairs that lead to the end which every man has before him, namely, glory and riches, to get there by various methods; one with caution, another with haste; one by force, another by skill; one by patience, another by its opposite; and each one succeeds in reaching the goal by a different method. One can also see of two cautious men the one attain his end, the other fail; and similarly, two men by different observances are equally successful, the one being cautious, the other impetuous; all this arises from nothing else than whether or not they conform in their methods to the spirit of the times. This follows from what I have said, that two men working differently bring about the same effect, and of two working similarly, one attains his object and the other does not."

"Therefore it is unnecessary for a prince to have all the good qualities I have enumerated, but it is very necessary to appear to have them. And I shall dare to say this also, that to have them and always to observe them is injurious, and that to appear to have them is useful; to appear merciful, faithful, humane, religious, upright, and to be so, but with a mind so framed that should you require not to be so, you may be able and know how to change to the opposite."

"God is not willing to do everything, and thus take away our free will and that share of glory which belongs to us."

"Is it better to be loved or feared?"

"A prince must not have any other object nor any other thought… but war, its institutions, and its discipline; because that is the only art befitting one who commands."

"Men ought either to be well treated or crushed, because they can avenge themselves of lighter injuries, of more serious ones they cannot; therefore the injury that is to be done to a man ought to be of such a kind that one does not stand in fear of revenge."

"A prudent man should always follow in the path trodden by great men and imitate those who are most excellent, so that if he does not attain to their greatness, at any rate he will get some tinge of it."

"Because there are three classes of intellects: one which comprehends by itself; another which appreciates what others comprehend; and a third which neither comprehends by itself nor by the showing of others; the first is the most excellent, the second is good, the third is useless."

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

"And here comes in the question whether it is better to be loved rather than feared, or feared rather than loved. It might perhaps be answered that we should wish to be both; but since love and fear can hardly exist together, if we must choose between them, it is far safer to be feared than loved."
