'Platonism, Nature and Environmental Crisis', Christian Platonism: A History, ed. Alexander J. B. Hampton, John Kenney (Cambridge: Cambridge University Press, forthcoming 2020). Abstract This examination makes the case that the tradition of Christian Platonism can constitute a valuable resource for addressing the long-running and increasingly-acute environmental crisis that threatens the global ecosystem and all who inhabit it. More than a scientific, technological or political challenge, the crisis requires a fundamental shift in the way humans understand nature and their place within it. Key to implementing this shift is the need to address the problematic anthropocentric conceptualisation of nature characteristic of the contemporary social imaginary that determines a wide range of present day economic, religious and scientific perspectives. The case made here is that Christian Platonism, and in particular its participatory ontology, can offer a radically non-anthropocentric alternative to the present-day understanding of nature, reconceptualising the way we understand the meaning, value, and way we know nature. © 2020 Alexander J.
