Explain and critically reflect on Vogel's account on the ontology of nature: "It is through our practices, which are in the first instance above all laboring practices, that the world around us is shaped into the world it is; our first access to that world is through such practices and indeed there is no access to it that does not involve them" Then, contrast this with Toadvine's alternative way of thinking about the relation between humans and the natural world that he advocates can be achieved through a method of "naturalizing phenomenology." What does Toadvine end up saying about nature, in terms of its being an environment, and about how we should proceed [e.g., by naturalizing phenomenology] in the construction of an environmental ethic?
