The term “mechanism” has been used in many different ways to express many different ideas. The new mechanists’ appropriation of the term is thus likely to cause unhelpful associations, and their liberalization of the term is likely to raise worries that the notion of mechanism has thereby been trivialized (see, e.g., Moss 2012 and Nicholson 2012). Here, we first distinguish the new mechanism from other doctrines with which it shares both name and family resemblance. We then discuss some things to which the new use of the term “mechanism” does not apply.
