In page Denis Diderot:

"

On the unity of nature, Diderot wrote, "Without the idea of the whole, philosophy is no more," and, "Everything changes; everything passes; nothing remains but the whole." He wrote of the temporal nature of molecules, and rejected emboîtement, the view that organisms are pre-formed in an infinite regression of non-changing germs. He saw minerals and species as part of a spectrum, and was fascinated with hermaphroditism. His answer to the universal attraction in corpuscular physics models was universal elasticity. His view of nature's flexibility foreshadows the discovery of evolution, but it is not Darwinistic in a strict sense.[2]
