“Tis better to have a dispute with honourable people than to have a victory over dishonourable ones. You cannot treat with the ruined, for they have no hostages for rectitude. With them there is no true friendship, and their agreements are not binding, however stringent they may appear, because they have no feeling of honour. Never have to do with such men, for if honour does not restrain a man, virtue will not, since honour is the throne of rectitude.”—The Art of Worldly Wisdom by Baltasar Gracián
I’ve loved this book since I was in high school.
