This work motivates the Combined Model for Combining Ideals, which Larry Temkin introduces in “sketch” form in Rethinking the Good, and goes on to begin filling in the details of the sketch. It argues that the Combined Model for Combining Ideals is most plausible when there are upper and lower caps on the extent to which an ideal can add to or subtract from the overall goodness of an outcome, but the caps for different values can and should differ.
