102 THE SHADOW OF THE WORLD’S FUTURE 
Science and technology have shown themselves 
capable of rendering splendid service, but they need 
to be the handmaidens of men good enough to be 
entrusted with them. They can be Furies and may 
hd, when they are the handmaidens of a spirit of 
evil. 
Another and similar aspect of international spirit of 
evil relationships calls for mention. When a people, 
having become subject to a control which has actually 
destroyed enormous numbers of them, a control which 
also has plunged them into economic ruin, endeavours 
by all sorts of subterfuges to spread its political creeds 
among other peoples, it makes a national goodwill to 
it fatuous, hinders economic relationships with it, and 
renders mutual migrations impossible. From this we 
see that political perfidy is a great hindrance to the 
population development of the world.
