A brief philosophical and methodological comment: without premeditation, our team once again subscribes to a particularly Franco-German approach as our anticipation work not only draws on the concept of "listening" and the unveiling of reality so dear to Heidegger, but also the approach advocated by Descartes, namely the definition of a rational method. Here, moreover, is a synthesis that should inspire those who are currently working to define the future characteristics of Euroland governance.So, should I short or go long on the Euro?
