That preface though:

AT a moment when Europe is in danger of a catastrophe worse than that of 1914 a book like this may be condemned as a distraction from the desperately urgent defence of civilization against modern barbarism.

Year by year, month by month, the plight of our fragmentary and precarious civilization becomes more serious. Fascism abroad grows more bold and ruthless in its foreign ventures, more tyrannical toward its own citizens, more barbarian in its contempt for the life of the mind. Even in our own country we have reason to fear a tendency toward militarization and the curtailment of civil liberty. Moreover, while the decades pass, no resolute step is taken to alleviate the injustice of our social order. Our outworn economic system dooms millions to frustration.
