If you think we can’t change the world, It just means you're not one of those that will

You cannot approach people who think differently with reason and logic if they don't know what that means. First, you have to appeal to their values to start with. If you attack them, you lose them.

If you remain conventional and don't change, you'll get along. You'll get along in the limited forms of insanity that exist out there. You'll never be able to keep a marriage together, you'll never be able to keep anything together, because the whole goddamn thing isn't together.

Self-centeredness will bring on the destruction of our world. National pride separates people. All people need the same thing. When you really get down to it, you'll find that all people need good food, clean water, clean air, and a decent environment, meaning education as to how to relate to one another and to avoid conflict, how to accept the differences where different people draw different conclusions.

War is the supreme failure of bridging the differences between nations.

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

In my work, I am not attempting to predict the future. I am only pointing out what is possible with the intelligent application and humane use of science and technology. This does not call for scientists to manage society. What I suggest is applying the methods of science to the social system for the benefit of human kind and the environment.
