 The basic conclusion that Potochnik and McGill and other levels skeptics draw from this is the following. The levels concept precludes a sophisticated discussion of philosophical and scientific issues by imposing an overly simplistic representation of science and nature. So, although perhaps no one would deny the attractiveness of ‘levels’ in seeking to make complex natural systems tractable to analysis, depicting these systems using the concept seems to do far more harm than good. Burton S. Guttman is very clear on this, stating that “if it is stated in any but the sloppiest and most general terms, [the concept of levels] is a useless and even misleading concept” (Guttman 1976: 112). Similarly, Miriam Thalos emphasizes “the conceit of levels” and argues that “the notion of levels provides no useful philosophical ideas whatever” (Thalos 2013: 13).
