In his , Aristotle argued that human beings try to further a variety of values by balancing them, stating that people try to find a middle road between excess and deficiency. The author develops and applies this idea to the values of economics, arguing that in the economy; freedom, justice and care are also balanced to further ends with scarce means. Freedom is furthered through market exchange, justice through a redistributive role of the state, and care through mutual gifts of labour and sharing of resources in the economy. The book argues that economics is, and has always been, about human values, which guide, enable, constrain and change economic behaviour.
