Montesquieu

Such are the prin­ci­ples of the three govern­ments, all of which does not mean that peo­ple in a given repu­blic are vir­tuous, but that they should be. Neither does it prove that in a given monar­chy peo­ple have honor, and in a par­ti­cu­lar des­po­tic state they live in fear, but that they should : other­wise the govern­ment will be imper­fect.
