According to Creasy, TSZ is the work in which Nietzsche’s most fully presents his proto-ecocentric vision for humanity’s re-naturalization. What she means by this is Nietzsche’s call for us to develop an ecological conscience: that is, to attune ourselves to the other-than-human world so that we may come to know ourselves better as natural beings and in that way identify and pursue the kinds of tasks that will most empower us and allow us to affirm life in its totality. This vision, she argues, can make important contributions to contemporary environmental philosophy and policy, especially as a critique of those anthropocentric frameworks and ideologies according to which the natural word has merely instrumental value (for example, as a resource).
