 Reactions to Batterman’s position include Redhead 2004, Belot 2005, Norton 2012, Pincock 2011a and 2012, Strevens 2008, Wayne 2011, 2012, and Bueno and French 2012. Objections range from claiming that asymptotic idealization are not needed to explain the target phenomenon to claiming that the “emergent qualitative features” that Batterman claims are yielded by asymptotic idealizations are not even genuine targets of explanation (this second aspect is connected to more general debates on emergence in physics). Strevens 2017 articulates, contra Norton 2012, what he takes to be the novel features of Batterman’s asymptotic (infinitary) idealizations that distinguish them from other non-infinitary idealizations (frictionless planes and ideal gases). He does so by appealing to cases from population genetics where one postulates “infinite populations”.
