A man has to work so hard so that something of his personality stays alive. A tomcat has it so easy, he has only to spray and his presence is there for years on rainy days.

One lives one's life under constant tension, until it's time to go for good

Our task is to widen our circle of compassion to include all living beings and all of nature

The greatest scientists are artists as well.

If you want different results, do not do the same things.

The world needs heroes and it's better they be harmless men like me than villains like Hitler

Hope that justice will be done to those brave men who stood up for their convictions.
