For this can be said of men in general: that they are ungrateful, fickle, hypocrites and dissemblers, avoiders of dangers, greedy for gain; and while… - Niccolò Machiavelli

Thus it is well to seem merciful, faithful, humane, sincere, religious, and also to be so; but you must have the mind so disposed that when it is needful to be otherwise you may be able to change to the opposite qualities. And it must be understood that a prince, and especially a new prince, cannot observe all those things which are considered good in men, being often obliged, in order to maintain the state, to act against faith, against charity, against humanity, and against religion. And, therefore, he must have a mind disposed to adapt itself according to the wind, and as the variations of fortune dictate, and, as I said before, not deviate from what is good, if possible, but be able to do evil if constrained.

When Machiavelli came to the end of his life, he had a vision shortly before giving up the ghost. He saw a small company of poor scoundrels, all in rags, ill-favoured, famished, and, in short, in as bad plight as possible. He was told that these were the inhabitants of paradise, of whom it is written, Beati pauperes, quoniam ipsorum est regnum caelorum. After they withdrew, innumerable serious and majestic personages appeared, who seemed to be sitting in a senate-house and dealing with the most important affairs of state. Among them he saw Plato, Aristotle, Seneca, Plutarch, Tacitus, and others of similar character; but he was told at the same time that those venerable personages, notwithstanding their appearance, were the damned, and the souls rejected by heaven, for Sapientia huius saeculi, inimica est Dei.. After this, he was asked to which of the groups he would choose to belong; he answered that he would much rather be in Hell with those great geniuses, to converse with them about affairs of state, than be condemned to the company of the verminous scoundrels that he had first been shown.

All the States and Governments by which men are or ever have been ruled, have been and are either Republics or Princedoms.
