Searching for building stones for a sustainable economy this article discusses content and reach of the principle of care. Based on the concept «Vorsorgendes Wirtschaften» with an understanding of time as timescapes the two authors - scientists in the fields of economics and environmental planning - broaden the notion of care towards « Vorsorge» (foresight, provision). Time is seen as a time complex with temporality (the dynamic aspect of time) and the past-present-future continuum and not as a single time. In this perspective caring today demands for integrating the future as the lifetime of our successors - it demands for «Vorsorge». Using their earlier developed category «(Re)Productivity» the authors make clear that and how care is included in «Vorsorge».
