At a time when people are questioning the fundamental assumptions of the free market, Beyond Self-Interest upends how we relate to capitalism. It does so not by rejecting the market, but by consigning it to its original function: as a tool of human development, rather than an end in itself. Krzysztof Pelc reminds us that commercial society was seen by its earliest theorists merely as a means of achieving our highest ends. It can still do this, if only we treat it once more as the tool it was originally conceived as. Prosperity is highly desirable, but only insofar as it contributes to human flourishing.
