“A Prince is likewise esteemed who is a stanch friend and a thorough foe, that is to say, who without reserve openly declares for one against another, this being always a more advantageous course than to stand neutral. For supposing two of your powerful neighbours come to blows, it must either be that you have, or have not, reason to fear the one who comes off victorious. In either case it will always be well for you to declare yourself, and join in frankly with one side or other. For should you fail to do so you are certain, in the former of the cases put, to become the prey of the victor to the satisfaction and delight of the vanquished, and no reason or circumstance that you may plead will avail to shield or shelter you; for the victor dislikes doubtful friends, and such as will not help him at a pinch; and the vanquished will have nothing to say to you, since you would not share his fortunes sword in hand.”
― Niccolò Machiavelli, The Prince

“Moreover, a Republic trusting to her own forces, is with greater difficulty than one which relies on foreign arms brought to yield obedience to a single citizen. Rome and Sparta remained for ages armed and free. The Swiss are at once the best armed and the freest people in the world.”
― Niccolò Machiavelli, The Prince

“Still, to slaughter fellow-citizens, to betray friends, to be devoid of honour, pity, and religion, cannot be counted as merits, for these are means which may lead to power, but which confer no glory.”
― Niccolò Machiavelli, The Prince

“When you see a Minister thinking more of himself than of you, and in all his actions seeking his own ends, that man can never be a good Minister or one that you can trust. For he who has the charge of the State committed to him, ought not to think of himself, but only of his Prince, and should never bring to the notice of the latter what does not directly concern him.”
― Niccolò Machiavelli, The Prince
