Full Idea
In aristocratic state there are two main sources of disorders: excessive inequality between those who govern and those who are governed, and the same degree of inequality among the different members of the ruling group [corps].
Gist of Idea
Great inequality between aristocrats and the rest is bad - and also among aristocrats themselves
Source
Baron de Montesquieu (The Spirit of the Laws (rev. 1757) [1748], 05.08)
A Reaction
This sounds like a very historically accurate observation, since aristocrats are always at one another's throats. But maybe junior aristocrats just need to be kept more firmly in their place.
