Scott Ferguson explores the implications of Modern Monetary Theory (MMT) for contemporary metaphysics and aesthetics. He asserts that only MMT can rescue society from neoliberal austerity by realizing the potential of money as a boundless public resource with an infinite capacity to serve human and environmental needs. In order to explain the resistance to MMT, Ferguson retraces the prevailing understanding of the money form to the political crises of the fourteenth-century republic of Florence. He presents the art of the Florentine renaissance as a response to these crises and the expression of the obsession with haecceity, or ‘thisness’, which has obscured money’s restorative potential for centuries. He also suggests that the sacramental theology of the thirteenth-century Dominican friar St. Thomas Aquinas offers a potential path out of the intellectual blind alley of haecceity, towards a just, tolerant, and ecologically sustainable future.
