Mass movements can rise and spread without belief in a God, but never without belief in a devil.

There is nothing more explosive than a skilled population condemned to inaction. Such a population is likely to become a hotbed of extremism and intolerance, and be receptive to any proselytizing ideology, however absurd and vicious, which promises vast action.

Social movements are at once the symptoms and the instruments of progress. Ignore them and statesmanship is irrelevant; fail to use them and it is weak.
