I believe that present day civilized man suffers from insufficient discharge of his aggressive drive.

I grew up in the large house and the larger garden of my parents in Altenberg. They were supremely tolerant of my inordinate love for animals.

Evil, by definition, is that which endangers the good, and the good is what we perceive as a value.

We do not take humor seriously enough.

I've been very lucky. I come from a very close family.

People were incredibly kind to our family and went out of their way to help.

I'm not a hero or a superstar. I'm an everyday guy. I feel happy when children approach me. I feel that something good is happening in life when little kids recognise me.

On the personal side, family is really important to me. I have a big family - five kids and 12 grandkids - so keeping that going is wonderful. And I do a lot of philanthropy. I'm chairman of the San Francisco Museum of Modern Art.
