The philosophical foundations of Keynes’s taxonomy and its contribution to economic pluralism

ABSTRACT This article seeks to recover the foundations of moral science and ethical philosophy underlying the thought of John Maynard Keynes in an attempt to understand the construction of the new taxonomy he proposed. In this regard, the influence of George Edward Moore’s philosophical method on Keynes’ thinking is noteworthy, allowing him to re-examine his initial training, whose first approach to economics was orthodox as a student of Alfred Marshall. As such, it can be said that Keynes used a “non-standard” methodology and historicism, importing elements from outside the discipline of economics, enabling a more pluralistic discussion within economic science.
