Abstract This paper is to a large extent an exercise in philosophical geography. It traces the way in which a resilient naturalist orientation has derived support, specifically in the analytic tradition, from a central structuring tenet of transcendental idealism. It attempts to bring out the philosophical reasons that drive this Kantian alliance. Attention then turns to the identification of two salient problems that confront this alliance in its most acceptable form. To the extent that a resilient naturalism is desirable, these problems need to be addressed. While the philosophical issue is brought into focus by attending specifically to developments in the analytic tradition, this is primarily a convenience. The preference for a resilient naturalism and the avoidance of metaphysical excess is not by any means confined to that tradition.
