“This country has been so rich in human and material resources that it is only recently that the importance of waste elimination has come to be realized. The material element received the first consideration, and in the comparatively few years during which the subject has received attention, an enormous amount has been done to conserve natural resources, to economize in the use.”

Preface, p. xiii
World Brain (1938)
Context: There has been … an enormous waste of human mental and physical resources in premature revolutionary thrusts, ill-planned, dogmatic, essentially unscientific reconstructions and restorations of the social order, during the past hundred years. This was the inevitable first result of the discrediting of those old and superseded mental adaptations which were embodied in the institutions and education of the past. They discredited themselves and left the world full of problems.
