I find man utterly unaware of what his wealth is or his fundamental capability is. He says time and again, "We can't afford it." For instance, we are saying now that we can't afford to do anything about pollution but after the costs of not doing something about pollution have multiplied many fold beyond what it would cost to correct it now, we will spend many fold what it would cost us now to correct it.

No man can prove upon awakening that he is the man who he thinks went to bed the night before, or that anything that he recollects is anything other than a convincing dream.

We must start with scientific fundamentals, and that means with the data of experiments and not with assumed axioms predicated only upon the misleading nature of that which only superficially seems to be obvious. It is the consensus of great scientists that science is the attempt to set in order the facts of experience.

We are not going to be able to operate our Spaceship Earth successfully nor for much longer unless we see it as a whole spaceship and our fate as common. It has to be everybody or nobody.

The explicable requires the inexplicable. Experience requires the nonexperienceable. The obvious requires the mystical.

The World has become too dangerous for anything less than Utopia.
