At the heart of our current environmental predicament lies the issue of our relationship with nature. Michael Bonnett's educational rehabilitation of nature, which might be called a 'metaphysical' turn in nature-related issues, brings us back to the core question of educational-philosophical thinking: how we are to understand ourselves and our relation to the world. In this paper, by confronting his environmental philosophy of education with what John McDowell, in his debate with Hubert Dreyfus, terms the 'pervasiveness thesis' -- that conceptual rationality in a relevant sense pervades human lives -- I try to offer an analytical supplement to the notion Bonnett entertains: that a phenomenological project to 'retrieve' nature and 'ecologise' education can have massive implications for the character of philosophy of education and the whole enterprise of education. I also argue a confluence of their nature-related ideas adds an educational nuance to the traditional picture of human beings as rational animals.
