“Previous generations were able to look upon intellectual and cultural progress as simply the inherited fruits of their forebears’ labours, which made life easier and more beautiful for them. But the calamities of our times show us that this was a fatal illusion. We see now that the greatest efforts are needed if this legacy of humanity’s is to prove a blessing not a curse. For whereas formerly it was enough for a man to have freed himself to some extent from personal egotism to make him a valuable member of society, to-day he must also be required to overcome national and class egotism.
“The importance of securing international peace was recognized by the really great men of former generations. But the technical advances of our times have turned this ethical postulate into a matter of life and death for civilized mankind to-day, and made the taking of an active part in the solution of the problem of peace a moral duty which no conscientious man can shirk. One has to realize that the powerful industrial groups concerned in the manufacture of arms are doing their best in all countries to prevent the peaceful settlement of international disputes, and that rulers can achieve this great end only if they are sure the vigorous support of the majority of their peoples. In these days of democratic government the fate of the nations hangs on themselves; each individual must alway bear that in mind.”
