Niccolo MachiavelliIt is much safer for the prince to be feared than loved, but he ought to avoid making himself hated.

Niccolo MachiavelliTherefore, a prudent ruler ought not to keep faith when by so doing it would be against his interest, and when the reasons which made him bind himself no longer exist.
