That was at about the same time as the works and theories of Auguste Comte were published.On the other hand, Magendie was considering himself in his own words "a mere scavenger of science trying to do science by collecting bits and pieces of nature's truths"; he was not after the grand scheme but after the "inventory of the nuts and bolts of the system". The French were also proud with Magendie's many discoveries and the extension of human knowledge in the areas of pathology, physiology and pharmacology and stood firmly behind his claim on the matter. Nevertheless, many Frenchmen (and most of our contemporaries) would have agreed with the English that the vivisections were not for the faint of heart.
