Following in Shionoya's Footsteps:

Perfectionism and in Keynes’s Political Philosophy

抄録

I　Preface The late 1980s and early 1990s saw an upsurge of interest in Keynesʼs philo-sophical thinking, possibly favoured by the availability of the full set of the Col-lected Works, the reunion of all his papers at Kingʼs （the catalogue was com-pleted in 1993） and soon after the microfilming of all his entire papers （Cox 1995）. 　　Over the last 30 years or so a large literature has developed on the subject, which has branched out in various directions. Two main concerns can be found in this literature: （a） the question of the continuity of Keynesʼs views and ap-proach, since the early philosophical essays, through the Treatise on Probability to the General Theory; （b） how Keynesʼs economics is intertwined with his ethics and epistemology. 　　In this paper I am focusing on a narrower topic （perfectionism and conse-quentialism in Keynesʼs ethics and political philosophy） following in the foot-steps of Yuichi Shionoya, whose contribution on the subject I revisited on the occasion of a commemoration held at the ESHET Conference in Paris, in May 2016. While much has been said in the literature on the non-consequentialist po-sition held by Keynes in ethics, less has been said on his being consequentialist in politics. Following in Shionoyaʼs footsteps, I would like to pursue the matter further, in particular on the implication for Keynesʼs economics.
