英文題為《有關癡愚》（ON STUPIDITY）

The moral

Stupidity is a taboo. It is not for nothing that we laugh at other people’s stupidity and do all we can to hide our own stupidity. How are you to live with your stupidity? How are we to avoid being the victims of our own stupidity any longer?

The battle against stupidity is pointless. The intelligence that attacks stupidity becomes entangled in its own web of thought patterns.

Prevention does not help. When you do something stupid, you always, by definition, find out too late. A stupid act cannot be prevented.

The most stupid solution is to be paralysed and dumb from fear of doing something stupid. Make your stupidity a personal, unique stupidity. If you fail, fail at the highest possible level. If you fall, fall with elegance and sing while you do it. Be as colourfully and versatilely stupid as you can. That way you avoid banality and stiffness, the two dangerous sides of stupidity. Do like me and turn stupidity into your strongest quality.
