Localizationism:

Scientists, impressed with the discoveries made by Galileo came to believe all nature functioned as a large cosmic clock, subject to the laws of physics, and began to explain individual living things, including our bodily organs, mechanistically, as though they too were machines. This idea that all nature was a vast mechanism, and that our organs were machine-like, replaced the two thousand year old Greek idea that viewed all nature as a vast living organism, and our bodily organs as anything but inanimate mechanisms.
