In man’s early days, competition with other creatures must have been critical, but this phase of our development is now finished. Indeed, we lack practice and experience nowadays in deeling with primitive conditions. I am sure that, without modern weapons, I would make a very poor show of disputing the ownership of a cave with a bear, and in this I don’t think that I stand alone. The last creature to compete with man was the mosquito, but even the mosquito has been subdued by attention to drainage and by chemical sprays.
Competition between ourselves, person against person, community against community, still persists, and it’s as fierce as it ever was.
But the competition of man against man is not the simple process envisioned in biology. It is not a simple competition for a fixed amount of food determined by physical environment, because the environment that determines our evolution is no longer essentially physical. Our environment is chiefly conditioned by the things we believe. Morocco and California are bits of the earth in very similar latitudes, both on the west coasts of continents with similar climates, and probably with rather similar natural resources. Yet their present development is wholly different, not only because of the different people even, but because of the different thoughts that exists in the minds of their inhabitants. This is the point I wish to emphasize. The most important factor in our environment is the state of our minds.
It is well known that where the white man has invaded a primitive culture, the most destructive effects have come not from physical weapons, but from ideas. Ideas are dangerous. The Holy Office knew this full well when it caused heretics to be burned in days gone by. Indeed, the concept of free speech only exists in our modern society, because when you are inside a community, you are conditioned by the conventions of the community to such a degree that it is very difficult to conceive of anything really destructive. It is only someone from outside that can inject dangerous thoughts. I do not doubt that it would be possible of inject ideas into the modern world that would utterly destroy us. Perhaps it will suffice to mention the nuclear bomb. Imagine the effect on a reasonably advanced technological society, one that still does not possess the bomb, of making it aware of the possibility, of supplying sufficient details to enable the thing to be constructed. Twenty or thirty pages of information handed to any of the major world powers around the year1925 would have been sufficient to change the course of world history. It is a strange thought, but I believe a correct one, that twenty or thirty pages of ideas and information would be capable of turning the present-day world upside down , or even destroying it. I have often tried to conceive of what those pages might contain, but of course I cannot do so, because I am a prisoner of the present day world, just as all of you are. We cannot think outside the particular patterns that our brains are conditioned to, or to be more accurate, we can only think a very little way outside, and then only if we are very original.
CA2U开办于二零零二年十月末，很高兴能与你一起度过青青校园的日子。 .
