ABSTRACT
The misfortunes of human beings may be divided into two classes: First, those inflicted by the non-human environment, and, second, those inflicted by other people. As mankind have progressed in knowledge and technique, the second class has become a continually increasing percentage of the total. In old times, famine, for example, was due to natural causes, and, although people did their best to combat it, large numbers of them died of starvation. At the present moment large parts of the world are faced with the threat of famine, but although natural causes have contributed to the situation, the principal causes are human. For six years the civilised nations of the world devoted all their best energies to killing each other, and they find it difficult suddenly to switch over to keeping each other alive. Having destroyed harvests, dismantled agricultural machinery, and disorganised shipping, they find it no easy matter to relieve the shortage of crops in one place by means of a superabundance in another, as would easily be done if the economic system were 143in normal working order. As this illustration shows, it is now man that is man's worst enemy. Nature, it is true, still sees to it that we are mortal, but with the progress in medicine it will become more and more common for people to live until they have had their fill of life. We are supposed to wish to live for ever and to look forward to the unending joys of heaven, of which, by miracle, the monotony will never grow stale. But in fact, if you question any candid person who is no longer young, he is very likely to tell you that, having tasted life in this world, he has no wish to begin again as a ‘new boy’ in another. For the future, therefore, it may be taken that much the most important evils that mankind have to consider are those which they inflict upon each other through stupidity or malevolence or both.
