In a monetary system, most of us live near our work with a house, car, and lifestyle we can afford (or, all too often, cannot afford), rather than the one we prefer. We are only as free as our purchasing power permits. Even many wealthy people today select a residence mainly to impress others with their status. Lacking a true sense of self worth, many live to impress others.

Our universities today are better equipped than ever, and the wars keep getting worse.

It takes a different value system if you wish to change the world.

There's no way to design a society that's optimal or utopian. It's better than the one that was. Systems always undergo change.

We're not sane enough yet to enter space until we learn to live together in peace on Earth.

You have to tell your children about the world they live in, about the discrepancies, about the things that don't work… So you have to bring it up with a scientific orientation so they learn to ask questions, and learn how to say the most difficult thing in the world: 'I don't know'.

You really don't want a job. What you want is access to those things you'd like to have.
