[I]t must be owned, that liberty is the perfection of civil society; but still authority must be acknowledged essential to its very existence: and in those contests, which so often take place between the one and the other, the latter may, on that account, challenge the preference. Unless perhaps one may say (and it may be said with some reason) that a circumstance, which is essential to the existence of civil society, must always support itself, and needs be guarded with less jealousy, than one that contributes only to its perfection, which the indolence of men is so apt to neglect, or their ignorance to overlook.
