When Amartya Sen defends his capability theory of well-being he contrasts it with the utility theory advocated by the classical utilitarians, including John Stuart Mill. Yet a closer examination of the two theories reveals that they are much more similar than they appear. Each theory can be interpreted in either a subjective or an objective way. When both are interpreted subjectively the differences between them are slight, and likewise for the objective interpretations. Finally, whatever differences may remain are less important than they might seem, since the two theories are developed by Sen and Mill for different purposes and are in that sense not genuine rivals.
