Between 1872 and 1882, Frederick Engels worked on a book titled The Dialectics of Nature that sought to apply Marxist dialectics to the natural world. Although it was never completed and is filled with dated ideas about science, it is a work that has earned the respect of some of the most important scientists on the left such as Stephen Jay Gould who praised its best known chapter that was issued separately as a pamphlet—The Part played by Labour in the Transition from Ape to Man. Long before people such as Barry Commoner and Rachel Carson were laying the groundwork for the eco-socialism of today, Engels anticipated the kind of contradictions that have led to three disastrous hurricanes: Katrina, Sandy and now Harvey.
