for a man has never the more particular quarrel with a prince, by marching openly and boldly against him for his own honour and according to his duty; if he does not love such a person, he does better, he esteems him.

Context

“And I know, amongst those who behave themselves most bravely in the present war, some whose manners are so gentle, obliging, and just, that they will certainly stand firm, whatever event Heaven is preparing for us. I am of opinion that it properly belongs to kings only to quarrel with kings; and I laugh at those spirits who, out of lightness of heart, lend themselves to so disproportioned disputes; for a man has never the more particular quarrel with a prince, by marching openly and boldly against him for his own honour and according to his duty; if he does not love such a person, he does better, he esteems him. And notably the cause of the laws and of the ancient government of a kingdom, has this always annexed to it, that even those who, for their own private interest, invade them, excuse, if they do not honour, the defenders.” source
