Iris Murdoch, Metaphysics as a Guide to Morals, Published April 7th 2003 by Vintage (first published 1992)
(This review appears in other locations besides this blog.) This book is hands down the second most important work in metaphysics in the last 200 years. The 1st most important work is Whitehead’s “Process and Reality;” taken together, the “200” year frame is quite possibly overly conservative.
Murdoch does not present us with a metaphysical “theory.” Rather, she presents a comprehensive argument about the nature and purpose of metaphysical *inquiry*. It is impossible to overstate the significance of such a shift in emphasis.
