There's allays two 'pinions; there's the 'pinion a man has of himsen, and there's the 'pinion other folks have on him. There'd be two 'pinions about a cracked bell, if the bell could hear itself
Argument is generally waste of time and trouble. It is better to present one’s opinion and leave it to stick or no as it may happen. If sound, it will probably in the end stick, and the sticking is the main thing.
He who would propagate an opinion must begin by making sure of his ground and holding it firmly. There is as little use in trying to breed from weak opinion as from other weak stock.
