Men are less hesitant about harming someone who makes himself loved than one who makes himself feared because love is held together by a chain of obligation which, since men are wretched creatures, is broken on every occasion in which their own interests are concerned; but fear is sustained by dread of punishment which will never abandon you.

[It., Perche, cosi come i buoni costumi, per mantenersi, hanno bisogno delli leggi; cosi le leggi per ossevarsi, hanno bisogno de' buoni costumi.]
