Some concerns with Polger and Shapiro’s view.

This paper provides some responses to Tom Polger and Larry Shapiro’s <italic>The Multiple Realization Book</italic> (2016). I first provide a description of the authors’ framework for thinking about multiple realization and the conditions they claim this involves. I explain what I think they get right and what they get wrong with this framework. After this, I then consider a few examples of multiple realization they discuss and the interpretations they offer. While I am sympathetic to several things they say about multiple realization, I also think there are some questions that have yet to be answered. [ABSTRACT FROM AUTHOR]
