The article discusses the current revolution of thought, economics, and social structure, and how it parallels drastic changes in history (such as mass extinctions for animals and plants). Huxley suggests that humanity must consciously evolve and adapt to these changes and that frequent and qualitative alterations are inevitable. The article outlines common trends in the current transformation such as increased planning and government involvement, a shift away from economic motives, and a growing need for international organization and cooperation. The author argues that these changes should be embraced with a focus on democratic principles, human values, and harnessing the creative spirit for a new social order.
