If all things keep changing, how can you become sane?

We will never know what anyone is really like, until everyone has economic security and doesn't have to answer to anyone else.

Nicola Tesla didn't say, 'I have to make wireless electricity!' The brain does not work that way.

We must look at alternatives objectively, and not try to fit the future into our present social mould.

We could either develop paradise on Earth or oblivion; wipe ourselves out, only the future will tell. It's what you do to make the future.

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

The system you're brought up under tries to make you like the people that succeeded in that system.
