"Science offers the possibility of far greater well-being for the human race than has ever been known before. It offers this on certain conditions: abolition of war, even distribution of ultimate power, and limitation of the growth of population. All these are much nearer to being possible than they ever were before. In Western industrial countries, the growth of population is almost nil; the same causes will have the same effect in other countries as they become modernized, unless dictators and missionaries interfere. The even distribution of ultimate power, economic as well as political, has been nearly achieved in Britain, and other democratic countries are rapidly moving towards it. The prevention of war? It may seem a paradox to say that we are nearer to achieving this than ever before, but I am persuaded that it is true."
