Well, sex is life. You know, if you don't do it anymore, you can take a spoon and go into the woods and dig yourself a hole and be finished! Eroticism is the driving force behind everything in the world.

An architect has to build the building from the inside out, not the outside in!

1973 was the first gasoline crisis in the world. That year, I designed the first aerodynamic truck, eating 40 percent less fuel. I put it on exhibit everywhere. It was 30 years ahead of its time. Nobody is building it today, and everybody still has problems with their boxy cars and trucks eating up fuel.

Everybody in Germany was for the -German cause. But then, after the war ended, when I heard the first Glenn Miller sound on the radio and these fantastic American music makers, I turned into a jazz fanatic. They called me Benny, after Benny Goodman. So, all of a sudden, the eyes of young Germans were opened to America - everything American was absolutely at the top of the list.

I consider myself a 3-D philosopher. I am not a designer at all. I studied aerodynamics, I studied philosophy, I studied sculpture. High technology on one side, and on the other side, art.

It is absolutely the central theme in my design philosophy - that life is erotic, period. The female body is one of the most extraordinary designs ever done in this universe.

If I had been president, I would have come out and declared: "Nothing there, ever! This place stays as it is. We make a big place there where people can pray about the errors we have made that those two towers had to fall."
