Historians of the sentimental school have sometimes regretted that royalty became absolute, while at the same time rejoicing that it installed plebeians in office. They deceive themselves. Royalty exalted plebeians just because it aimed at becoming absolute; it became absolute because it had exalted plebeians.
It is always utterly impossible to build an aggressive Power with aristocrats. Care for family interests, class solidarity, educational influences, all combine to dissuade them from handing over to the state the independence and fortunes of their fellows.
The march of absolutism, which subdues the diversity of customs to the uniformity of laws, wars against local attachments on of a concentration of loyalties on the state, douses all other fires of life that one may remain alight, and substitutes for the personal ascendancy of the notables the mechanical control of an administration – such a system is, I say, the natural destroyer of the traditions on which is founded the pride of aristocracies and of the patronage which gives them their strength
Resistance is, therefore, the business of aristocracies.
