Salon interview (2000)
Context: In the old movies, yes, there always was the happy ending and order was restored. As it is in Shakespeare's plays. It's no disgrace to, in the end, restore order. And punish the wicked and, in some way, reward the righteous.

Reflections on the Revolution in France (1790)
Context: Where popular authority is absolute and unrestrained, the people have an infinitely greater, because a far better founded, confidence in their own power. They are themselves, in a great measure, their own instruments. They are nearer to their objects. Besides, they are less under responsibility to one of the greatest controlling powers on the earth, the sense of fame and estimation. The share of infamy that is likely to fall to the lot of each individual in public acts is small indeed; the operation of opinion being in the inverse ratio to the number of those who abuse power. Their own approbation of their own acts has to them the appearance of a public judgment in their favor. A perfect democracy is, therefore, the most shameless thing in the world. As it is the most shameless, it is also the most fearless. No man apprehends in his person that he can be made subject to punishment.
