I contrast two roles for environmental philosophers-''applied philosop
hy'' and ''practical philosophy''-and show that the strategy of applie
d philosophy encourages an axiological and monistic approach to theory
building. I argue that the mission of applied philosophy, and the mon
istic theory defended by J. Baird Callicott, in particular, tends to s
eparate philosophers and their problems from real management issues be
cause applied philosophers and moral monists insist that theoretical e
xploration occurs independent of, and prior to, applications in partic
ular situations. This separation of theory and practice suggests that
philosophers are likely to be effective in policy discussions only to
the degree that they can offer unquestioned theories that adjudicate r
eal problems. Callicott offers his monistic, ontological approach as u
niversal guidance to environmental activists and decision makers, argu
ing that ecosystems and communities are moral subjects that can ''own'
' their own inherent value. Callicott's theory, however, faces a cruci
al, unanswered theoretical dilemma which illustrates the impossibility
of the dual task Callicott has set for his theory-to provide a single
, ontological unification of ethics under nonanthropocentric holism an
d to capture the fine nuances of ethical obligations as experienced in
varied communities. I also show that monistic assumptions have led to
an unfortunate interpretation of Aldo Leopold's land ethic and that a
pluralist and pragmatist direction is likely to provide a more effica
cious and theoretically defensible direction for further study of envi
ronmental philosophy in a more practical mode.
