Conquered states that have been accustomed to liberty and the government of their own laws can be held by the conqueror in three different ways. The first is to ruin them; the second, for the conqueror to go and reside there in person; and the third is to allow them to continue to live under their own laws, subject to a regular tribute, and to create in them a government of a few, who will keep the country friendly to the conqueror
Niccolo MachiavelliAnd what physicians say about disease is applicable here: that at the beginning a disease is easy to cure but difficult to diagnose; but as time passes, not having been recognized or treated at the outset, it becomes easy to diagnose but difficult to cure. The same thing occurs in affairs of state; for by recognizing from afar the diseases that are spreading in the state (which is a gift given only to the prudent ruler), they can be cured quickly; but when, not having been recognized, they are not recognized and are left to grow to the extent that everyone recognizes them, there is no longer any cure.

From this arises the question whether it is better to be loved more than feared, or feared more than loved.
