Many philosophical naturalists eschew analysis in favor of discovering metaphysical truths from the a posteriori, contending that analysis does not lead to philosophical insight. A countercurrent to this approach seeks to reconcile a certain account of conceptual analysis with philosophical naturalism; prominent and influential proponents of this methodology include the late David Lewis, Frank Jackson, Michael Smith, Philip Pettit, and David Armstrong. Naturalistic analysis (sometimes known as "the Canberra Plan" because many of its proponents have been associated with Australian National University in Canberra) is a tool for locating in the scientifically given world objects and properties we quantify over in everyday discourse.

This collection gathers work from a range of prominent philosophers who are working within this tradition, offering important new work as well as critical evaluations of the methodology. Its centerpiece is an important posthumous paper by David Lewis, "Ramseyan Humility," published here for the first time. The contributors first address issues of philosophy of mind, semantics, and the new methodology's a priori character; then turn to matters of metaphysics; and finally consider problems regarding normativity. Conceptual Analysis and Philosophical Naturalism is one of the first efforts to apply this approach to such a wide range of philosophical issues.
