Nature is political, John Meyer argues, because it constitutes people and so their politics; moreover, interpretations of nature can only be controversial and so contested. Meyer is an environmentalist who believes that contemporary theoretical thinking about politics and the environment is mostly mistaken. Environmental philosophy, in particular, is criticized as involving wasted effort because it emphasizes justifications for intrinsic value in nature. This emphasis implies that the political challenge is one of convincing enough people to adopt some ecologically benign worldview. But as Meyer rightly points out, most people already evidence a vague commitment to environmental values, and so the real question is how to activate such commitments.
