There are plenty of problems in the world, many of them interconnected. But there is no problem which compares with this central, universal problem of saving the human race from extinction.

Not all problems have a technological answer, but when they do, that is the more lasting solution.

Every solution breeds new problems.

The only solutions that are ever worth anything are the solutions that people find themselves.

People are not problems to be solved. They are mysteries to be explored.

The solution for mankind is of a spiritual nature. It is not a political or religious solution. It's the ability to love each other. That's the only solution I see.

We cannot solve life's problems except by solving them.

Just because we can't find a solution it doesn't mean that there isn't one.
