 The example D’Arms and Jacobson use is envy. According to them, it (broadly speaking) presents a rival in a negative light in virtue of having a desirable possession. The right kind of reasons bearing on whether a rival is enviable are thus those that have to do with what she possesses and its desirability relative to what you have. If a colleague gets a promotion you wanted, envy may be fitting in this sense, and consequently, given a fitting attitudes account of evaluative properties, the colleague will be enviable. This is the case even if envy is morally or prudentially inappropriate – the latter kind of reasons do not bear on the fittingness of envy.
