In the 1840s, a new type of materialism was developed, influenced by the methodological advancements in biology and the decline of idealistic philosophy .
The first half of the book explores Ernst Haeckel's biogenetic law (recapitulation)—the discredited idea that embryonic developmental stages replay the evolutionary transitions of adult forms of an organism's past descendants—and how this idea influenced thinking in biology, theology, and psychology.
