There is only one difference between a madman and me. I am not mad.

There is only one difference between a madman and me. The madman thinks he is sane. I know I am mad.

The only difference between me and a madman is that I'm not mad.

I am no bird; and no net ensnares me; I am a free human being with an independent will.

I am not a madman or a nut.

The only difference between me and a madman is that I am not mad
