The chief effect of talk on any subject is to strengthen one's own opinions, and, in fact, one never knows exactly what he does believe until he is warmed into conviction by the heat of attack and defence.

It is only about things that do not interest one that one can give a really unbiased opinion, which is no doubt the reason why an unbiased opinion is always absolutely valueless.

When anyone says they often think something, it means they've just thought of it now.

The fact that an opinion is widely held is no evidence whatever that it is not utterly absurd.

I would like to be able to admire a person's opinions as I would their dog -without being expected to take it home with me.

If you want to discover your true opinion of anybody, observe the impression made on you by the first sight of a letter from him.

What others think of us would be of little moment did it not, when known, so deeply tinge what we think of ourselves.

I think everyone is entitled to my opinion.

In view of the stupidity of the majority of people, a widely held opinion is more likely to be foolish than sensible.
