"The peoples of the world... are divided into four groups... This is of course a wide generalization... First, the ignorant masses... They can be easily... swept into a collective activity by leaders of any school of thought which is clever enough, and emotional enough, to appeal to material desires, to love of country... They can be controlled by fear, and thus aroused to action by emotional appeal... Their conditions must be bettered, but not through bloodshed and exploitation. Secondly, the middle classes... the bulk of the nations, the bourgeoisie - intelligent, diligent, enquiring, narrow-minded... They are...without exception, the most powerful element in any nation... the most fruitful field from which the new leaders and organizers are being drawn... they are the determining factor in world affairs... Because of their intelligence... they provide the most powerful group in the world in each nation... Thirdly, the thinkers...the intelligent and highly educated men and women, who sense ideas and formulate them into ideals. These people speak the words, write the articles and books, and utilise all the known methods to reach and educate the general public... sometimes for good, and sometimes for selfish ends. They play upon the human mind, as a musician plays upon his instrument... Some few, more perhaps than might appear, are working selflessly under the inspiration of the new era... dedicated to the amelioration of human conditions, and the betterment of world affairs along certain lines... They are found in every government, party, society, and organization... p.174-175"
