In this chapter, Hans Herlof Grelland argues that care is an inherent element in how we can see the world. It is included in our lifeworld perspective. By using Heidegger and Kierkegaard, Grelland thereby shows how sustainability and care can be argued from a philosophical perspective. This provides a thought-provoking introduction to concern or care, setting the scene for a strategy in philosophical terms which highlights the role of education. "Care implies responsibility, and awareness of this responsibility is the beginning of the change which has to come".
