I never considered a difference of opinion in politics, in religion, in philosophy, as cause for withdrawing from a friend.

If it is true to say of the lazy that they kill time, then it is greatly to be feared that an era which sees its salvation in public opinion, this is to say private laziness, is a time that really will be killed.

There is no such thing as public opinion. There is only published opinion.

I'm a role model for those who dare to be different. For those who dare to take a stand in their life and have an opinion.

One man adheres to an opinion because he prides himself on having come upon it by himself; another because he has learned it with effort, and is proud of having grasped it: thus both out of vanity.

I was myself so smitten in public opinion that it was the almost universal view that my political life was at last ended.
