کتاب The Prince

one change always leaves the toothing for another.

for men change their rulers willingly, hoping to better themselves, and this hope induces them to take up arms against him who rules: wherein they are deceived, because they afterwards find by experience they have gone from bad to worse.

Therefore, my son, if you wish to please me, and to bring success and honour to yourself, do right and study, because others will help you if you help yourself.

he who thinks new favours will cause great personages to forget old injuries deceives himself.

And the usual course of affairs is that, as soon as a powerful foreigner enters a country, all the subject states are drawn to him, moved by the hatred which they feel against the ruling power.

The wish to acquire is in truth very natural and common, and men always do so when they can, and for this they will be praised not blamed; but when they cannot do so, yet wish to do so by any means, then there is folly and blame.
