8. Abstraction and Reality

One can make a strong point of saying these things to people today, but whether they will also take it as a strong point is another question. Something that was just as intelligent as the politicians' idea of the potential duration of the war—again I am not being ironical—were the reasons given by an enlightened group of medical men when the first railways were being built in Central Europe. Speaking on the basis of medical knowledge at the time, not just a single eccentric but a whole group of medical men—I have spoken of this before—said that the railways should not be built because the human nervous system would not be able to cope with them. This is on historical record; it happened in 1838. Not so long ago, therefore, the professional opinion was that railways should not be built. If, however, people were to build railways after all—so the document says—high board fences should be put on either side of the tracks, so that the farmers would not see the trains passing by and suffer concussion as a result. Yes, it is easy to laugh afterwards, when reality has ignored such arguments. People laugh about it afterwards, but there are some elemental spirits who laugh about human folly when it is being committed, or indeed even before scientists come up with such foolish notions.
