source: Kane B　2016年9月23日
It is natural to think of the world as being divided into a hierarchy of levels: on the lowest level there are fundamental particles such as quarks, electrons, photons, etc; at a higher level, atoms and molecules; at a higher levels, cells; at a higher level, organisms; and so on. This video examine various ways we might try to make the notion of levels precise. I then outline Jaegwon Kim's exclusion argument, which poses a serious problem for the levels picture.
