The world is not run by thought, nor by imagination, but by opinion. The man who never alters his opinion is like standing water, and breeds reptiles of the mind. Every new opinion, at its starting, is precisely in a minority of one. Goodman Opinion has caused more trouble on this little earth than plagues or earthquakes.
Some men are just as sure of the truth of their opinions as are others of what they know.
A fellow can't keep people from having a bad opinion of him, but he can keep them from being right about it.
