"Back to Methuselah: A Metabiological Pentateuch" by Bernard Shaw is a cycle of five plays written between 1918 and 1920. Shaw proposes a radical solution to humanity's problems: people must evolve to live for centuries instead of decades. Only through extended lifespans, he argues, can humans gain the wisdom needed to govern complex civilizations. The plays span from the Garden of Eden to the year 31,920, exploring how humanity might transform through Creative Evolution and the Life Force to achieve this extraordinary longevity.
