On a visit to Leningrad some years ago I consulted a map to find out where I was, but I could not make it out. I could see several enormous churches, yet there was no trace of them on my map. When finally an interpreter came to help me, he said “We don’t show churches on our maps.” Contradicting him, I pointed to one that was very clearly marked. “This is a museum,” he said, “not what we call a ‘living church.’ It is only the ‘living churches’ we don’t show.”
It then occurred to me that this was not the first time I had been given a map that failed to show many of the things I could see right in front of my eyes. All through school and university I had been given maps of life and knowledge on which there was hardly a trace of many of the things that I most cared about and that seemed to me to be of the greatest possible importance for the conduct of my life. I remembered that for many years my perplexity was complete; and no interpreter came along to help me. It remained complete until I ceased to suspect the sanity of my perceptions and began, instead, to suspect the soundness of the maps.
The maps of real knowledge, designed for real life, showed nothing except things which allegedly could be proved to exist. The first principle of the philosophical mapmakers seemed to be “If in doubt, leave it out,” or put it into a museum. It occurred to me, however, that the question of what constitutes proof was a very subtle and difficult one. Would it not be wiser to turn the principle into its opposite and say: “If in doubt, show it prominently“? After all, matters that are beyond doubt are, in a sense, dead; they do not constitute a challenge to the living.
To accept anything as true means to incur the risk of error. If I limit myself to knowledge that I consider true beyond doubt, I minimize the risk of error but I maximize, at the same time, the risk of missing out on what may be the subtlest, most important and most rewarding things in life.
