Environmental philosophy is well discussed in contemporary times. Yet, skeptics raise an important question: What is philosophical in environmental philosophy? The question is pertinent enough when one does not find anything philosophically substantive in environmental philosophy, namely substantive metaphysical, epistemological, axiological, and ethical inquiries in this field. At best a few fashionable philosophers talk about intrinsic value in nature. This is a serious threat to environmental philosophy that there is hardly any philosophy in it. In this paper, I argue that (...) the “real business of philosophy” should go for an urgent makeover because metaphysics apart, philosophically relevant inquiries into environmental matters include epistemological, axiological, and ethical inquiries. Interestingly, these important inquiries are not watertight in so far as environmental matters are in question. In the first part of the paper, I take a renewed look at environmental epistemology and then proceed to consider environmental metaphysics. Furthermore, I argue for a comprehensive epistemological–metaphysical–axiological–ethical inquiry that makes environmental philosophy, a vibrant philosophical enterprise. (shrink)
