Douglas Adams
All opinions are not equal. Some are a very great deal more robust, sophisticated and well supported in logic and argument than others.

Francis Bacon
It were better to have no opinion of God at all, than such an opinion, as is unworthy of him.

George Eliot
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

Isaac Asimov
I suppose he’s entitled to his opinion, but I don’t suppose it very hard.

Jane Austin

Samuel Butler
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.

Samuel Butler
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.
