Attempts of which the motive is ambition arise in a different way as well as in those already mentioned. There are men who will not risk their lives in the hope of gains and honors however great, but who nevertheless regard the killing of a tyrant simply as an extraordinary action which will make them famous and honorable in the world; they wish to acquire, not a kingdom, but a name. It is rare, however, to find such men; he who would kill a tyrant must be prepared to lose his life if he fail. He must have the resolution of Dion, who, when he made war upon Dionysius, took with him very few troops, saying 'that whatever measure of success he might attain would be enough for him, even if he were to die the moment he landed; such a death would be welcome to him.' this is a temper to which few can attain.
Once more, tyrannies, like all other governments, are destroyed from without by some opposite and more powerful form of government. That such a government will have the will to attack them is clear; for the two are opposed in principle; and all men, if they can, do what they will. Democracy is antagonistic to tyranny, on the principle of Hesiod, 'Potter hates Potter,' because they are nearly akin, for the extreme form of democracy is tyranny; and royalty and aristocracy are both alike opposed to tyranny, because they are constitutions of a different type. And therefore the Lacedaemonians put down most of the tyrannies, and so did the Syracusans during the time when they were well governed.
Again, tyrannies are destroyed from within, when the reigning family are divided among themselves, as that of Gelo was, and more recently that of Dionysius; in the case of Gelo because Thrasybulus, the brother of Hiero, flattered the son of Gelo and led him into excesses in order that he might rule in his name. Whereupon the family got together a party to get rid of Thrasybulus and save the tyranny; but those of the people who conspired with them seized the opportunity and drove them all out. In the case of Dionysius, Dion, his own relative, attacked and expelled him with the assistance of the people; he afterwards perished himself.
There are two chief motives which induce men to attack tyrannies-hatred and contempt. Hatred of tyrants is inevitable, and contempt is also a frequent cause of their destruction. Thus we see that most of those who have acquired, have retained their power, but those who have inherited, have lost it, almost at once; for, living in luxurious ease, they have become contemptible, and offer many opportunities to their assailants. Anger, too, must be included under hatred, and produces the same effects. It is often times even more ready to strike- the angry are more impetuous in making an attack, for they do not follow rational principle. And men are very apt to give way to their passions when they are insulted. To this cause is to be attributed the fall of the Peisistratidae and of many others. Hatred is more reasonable, for anger is accompanied by pain, which is an impediment to reason, whereas hatred is painless.
In a word, all the causes which I have mentioned as destroying the last and most unmixed form of oligarchy, and the extreme form of democracy, may be assumed to affect tyranny; indeed the extreme forms of both are only tyrannies distributed among several persons.
Kingly rule is little affected by external causes, and is therefore lasting; it is generally destroyed from within. And there are two ways in which the destruction may come about; (1) when the members of the royal family quarrel among themselves, and (2) when the kings attempt to administer the state too much after the fashion of a tyranny, and to extend their authority contrary to the law.
Royalties do not now come into existence; where such forms of government arise, they are rather monarchies or tyrannies. For the rule of a king is over voluntary subjects, and he is supreme in all important matters; but in our own day men are more upon an equality, and no one is so immeasurably superior to others as to represent adequately the greatness and dignity of the office. Hence mankind will not, if they can help, endure it, and any one who obtains power by force or fraud is at once thought to be a tyrant. In hereditary monarchies a further cause of destruction is the fact that kings often fall into contempt, and, although possessing not tyrannical power, but only royal dignity, are apt to outrage others. Their overthrow is then readily effected; for there is an end to the king when his subjects do not want to have him, but the tyrant lasts, whether they like him or not.
The destruction of monarchies is to be attributed to these and the like causes.
