My unconscious knows more about the consciousness of the psychologist than his consciousness knows about my unconscious. - Karl Kraus

The devil is an optimist if he thinks he can make people meaner.

I have often been asked to be fair and view a matter from all sides. I did so, hoping something might improve if I viewed all sides of it. But the result was the same. So I went back to viewing things only from one side, which saves me a lot of work and disappointment. For it is comforting to regard something as bad and be able use one's prejudice as an excuse.

The development of technology will leave only one problem: the infirmity of human nature.
