The man whose public spirit is prompted altogether by humanity and benevolence, will respect the established powers and privileges even of individuals, and still more those of the great orders and societies, into which the state is divided.

Context

“The violence of the party, refusing all palliatives, all temperaments, all reasonable accommodations, by requiring too much frequently obtains nothing; and those inconveniencies and distresses which, with a little moderation, might in a great measure have been removed and relieved, are left altogether without the hope of a remedy. The man whose public spirit is prompted altogether by humanity and benevolence, will respect the established powers and privileges even of individuals, and still more those of the great orders and societies, into which the state is divided. Though he should consider some of them as in some measure abusive, he will content himself with moderating, what he often cannot annihilate without great violence. When he cannot conquer the rooted prejudices of the people by reason and persuasion, he will not attempt to subdue them by force;” source
