Haeckel's 1899 bestseller — The Riddle of the Universe — that brought monism to a mass audience and argued for evolution as the foundation of a comprehensive scientific worldview.
Die Welträtsel was one of the publishing phenomena of the early twentieth century. Sold over half a million copies in Germany alone, translated into more than two dozen languages, and remained in print for decades. Haeckel's argument was that science had solved—or was on the way to solving—the fundamental riddles of the universe, and that the solution was monism: one substance, one law, no supernatural additions to nature. The book was simultaneously a popular exposition of Darwinism, a polemical rejection of theological dualism, and a program for a new philosophical worldview grounded in natural science. It made Haeckel Continental Europe's most famous evolutionist and one of the most controversial intellectual figures of his era.
