This thinker chronicled a debate between Cuvier and Saint-Hilaire in his Principles of Zoologic Philosophy.  He claimed that nature is driven by compensating loss because of "the budget of nature."  He stated his disbelief in the use of experiments as proof and hinted at his dislike of math in science in his The Experiment as Mediator between Subject and Object. This thinker proposed an "osteological type," an archetype upon which animals are based, in one work and discussed the homology of leaves in another; those are his Metamorphosis of Animals and Metamorphosis of Plants, respectively. His most famous attempt at science deals with the "physiological, physical, and chemical" forms of the title concept, which can arise from the action of a "turbid medium" and are represented on a triangle.
