No one wins when the political field is populated exclusively by the incorrigible right and the bemused left.

On the subject of Malassis, I will tell you that I marvel at his courage, at his activity, and his incorrigible gaiety.

He revolted against it, as a thing more provoking, more incorrigible than mere womanhood.

He was master, he said, of the lives and property of these incorrigible rebels, and he would do with them as he pleased.

Even on his father the incorrigible lad seems on more than one occasion to have tried his little game.
