Book excerpt: "Who discovered photosynthesis? Not many people know. Jan IngenHousz' name has been forgotten, his life and works have disappeared in the mists of time. Still, the tale of his scientific endeavour shows science in action. Not only does it open up an undisclosed chapter of the history of science, it is an ideal (as under researched) episode in the history of science that can help to shine some light on the ingredients and processes that shape the development of science. This paves the way for a fresh multidimensional approach in the philosophy of science: towards an "ecology of science"."--P. [4] of cover.
