The history of human opinion is scarcely anything more than the history of human errors.

Wind buffs up empty bladders; opinion, fools.

We think very few people sensible, except those who are of our opinion.

Even good opinions are worth very little unless we hold them in the broad, intelligent, and spacious way.

Opinions cannot survive if one has no chance to fight for them.

Man is a gregarious animal and much more so in his mind than in his body. A golden rule; judge men not by their opinions but by what their opinions have made of them.

Error of opinion may be tolerated where reason is left free to combat it.

People talk fundamentals and superlatives and then make some changes of detail.

Opinion is that exercise of the human will which helps us to make a decision without information.

Few people are capable of expressing with equanimity opinions which differ from the prejudices of their social environment. Most people are even incapable of forming such opinions.
