人は自ら信ずる擬似的な環境に反応する
【環境は間接的にしか知り得ず、知っている世界と、知る必要がある世界が異なり矛盾することさえある。このことは、他の人々や時代については気づくが、自分のことになると、真であると信じることが、環境そのものであるかのように行動し失敗する。(ウォルター・リップマン(1889-1974))】Looking back we can see how indirectly we know the environment in which nevertheless we live. We can see that the news of it comes to us now fast, now slowly; but that whatever we believe to be a true picture, we treat as if it were the environment itself. It is harder to remember that about the beliefs upon which we are now acting, but in respect to other peoples and other ages we flatter ourselves that it is easy to see when they were in deadly earnest about ludicrous pictures of the world. We insist, because of our superior hindsight, that the world as they needed to know it, and the world as they did know it, were often two quite contradictory things. We can see, too, that while they governed and fought, traded and reformed in the world as they imagined it to be, they produced results, or failed to produce any, in the world as it was. They started for the Indies and found America. They diagnosed evil and hanged old women. They thought they could grow rich by always selling and never buying. A caliph, obeying what he conceived to be the Will of Allah, burned the library at Alexandria.
