Callicott held the position of Professor of Philosophy and Natural Resources at the University of Wisconsin – Stevens Point from 1969 to 1995, where he taught the world ’ s first course in environmental ethics in 1971.

Aldo Leopold's A Sand County Almanac is one of environmental philosophy ’ s seminal texts, and Callicott is widely considered to be the leading contemporary exponent of Leopold's land ethic.

Callicott ’ s book In Defense of the Land Ethic ( 1989 ) explores the intellectual foundations of Leopold's outlook and seeks to provide it with a more complete philosophical treatment ; and a following publication titled Beyond the Land Ethic ( 1999 ) further extends Leopold ’ s environmental philosophy.

The addition of Callicott ’ s expertise helped cement its standing as the world's leading program in the field.

Callicott traces the conceptual foundations of the Leopold land ethic first back to Charles Darwin ’ s analysis of the “ moral sense ” in the Descent of Man and ultimately to David Hume ’ s grounding of ethics in the “ moral sentiments ” espoused in An Enquiry Concerning the Principles of Morals.

The tradition of dichotomous thinking in Western philosophy inclines most philosophers to dismiss Hume ’ s ethics as a kind of irrational emotivism, despite the fact that, Callicott believes, Hume clearly provides a key role for reason in moral action and judgment.

The distinctiveness of environmental ethics turns on the question of non-anthropocentrism, and that question turns on the question of nature ’ s intrinsic value, according to Callicott.

Callicott offers a subjectivist theory of nature ’ s intrinsic value: he does not challenge the modern classical distinction between subject and object, but rather insists that all value originates in subjects ( human or otherwise ) and is conferred by those subjects on various objects.

In response to Callicott ’ s elaboration of the Aldo Leopold land ethic, the land ethic ( and, by implication, Callicott ’ s own non-anthropocentric, holistic environmental ethic to the extent that it may differ from Leopold ’ s ) has been subject to the charge of “ ecofascism ,” notably leveled by Tom Regan.

Callicott ’ s comparative environmental philosophy also involves a tightrope walk between pluralism and monism.

Callicott ’ s justification for this claim is an analysis based on the following criteria for tenability: self-consistency ; comprehensiveness ; self-correction ; universality ; and beauty.

Most recent criticisms have been leveled at Callicott ’ s works addressing the idea of wilderness, the sanctum sanctorum of the twentieth-century environmental movement.

Some scholars acknowledge the intellectual merits of Callicott ’ s critique of the wilderness idea, but regard it as both a betrayal of one of Aldo Leopold ’ s most cherished causes and as giving aid and comfort to the environmental movement ’ s enemies.

* Callicott, J. Baird ( 1994 ).

Callicott is, perhaps, best known for his research which explores an Aldo Leopold ethic as a response to global climate change.

Callicott supports a holistic, non-anthropocentric environmental ethic which is in accordance with Leopold's view that " A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community.

J. Baird Callicott is an American philosopher whose work has been at the forefront of the new field of environmental philosophy and ethics.

Callicott is co-Editor-in-Chief with Robert Frodeman of the award-winning, two-volume A-Z Encyclopedia of Environmental Ethics and Philosophy, published by Macmillan in 2009.

It is wrong when it tends otherwise " — Callicott espouses a holistic, non-anthropocentric environmental ethic.

Callicott has worked with conservation biologists to develop a philosophy of conservation and conservation values and ethics, based in part on the recent paradigm shift in ecology from what he calls the “ balance of nature ” to the “ flux of nature .” He has been a strong critic of the “ received wilderness idea ”: the idea that wildernesses are places that are “ untrammeled by man, where man himself is a visitor who does not remain .” That idea, Callicott claims in The Great New Wilderness Debate ( 1998 ), perpetuates a pre-Darwinian human-nature dualism ; in effect, it “ erases ” from collective memory the indigenous inhabitants of North America and Australia, liberating the current inhabitants of those continents from disturbing thoughts of their own heritage of genocide.

In sum, Callicott is a theoretical monist and an interpersonal and normative pluralist.

As Andrew Light observes, Callicott does not insist that the Leopold land ethic is based on the uniquely true worldview of evolutionary biology and ecology.

When the details of that worldview are shown to be inconsistent with themselves or unable to account for all the facts, the theory is revised accordingly ; the evolutionary-ecological worldview is thus self-correcting and is therefore, Callicott believes, becoming ever more refined.

Callicott counters that his quarrel is with an idea, not the places trammeled by the idea, the preservation of which places he appears to be as ardently supportive as any other environmentalist.

This idea indicates by its very name what the primary goal of wildland preservation is, whereas the wilderness idea is historically associated with outdoor recreation and thus, Callicott claims, confuses the preservation issue and fosters incoherent and contradictory wildlands-use policies.

As “ an expatriate Southerner, fresh from the pitched battles of the Civil Rights struggle in Memphis, Tennessee ,” Callicott believed that “ the environment was under wholesale assault from every direction with no surcease in sight ” and that “ Civil Rights was a cause already won in the republic of ideas and in the courts ( if not on Main Street in Memphis ).” He “ was a concerned citizen, but was also, more particularly, a challenged philosopher .” So Callicott asked “ how, as a philosopher, could contribute to a rethinking of human nature and a reconstruction of human values to help bring them into line with the relatively new ideas about the nature of the environment emerging from ecology and the new physics .”

Callicott was instrumental in developing the field of environmental philosophy and in 1971 taught the world's first course in environmental ethics.

For 26 years, Callicott lived and taught in the northern reaches of Wisconsin's sand counties, located on the Wisconsin River, just ninety miles from Aldo Leopold's storied shack and John Muir's first homestead on Fountain Lake, the region that stirred the souls of two very influential environmental thinkers.

Callicott writes that “ the landscape that had helped shape and inspire the nascent evolutionary-ecological thought of the youthful Muir and that of the mature Leopold was the perfect setting for ( me ) to inaugurate ( my ) life-long vocation as a founder of academic environmental philosophy .” In 1995, he joined the Department of Philosophy and Religion Studies at the University of North Texas in Denton.

Callicott believes that an adequate environmental ethic — an environmental-ethics paradigm that addresses actual environmental concerns — must be holistic.

Callicott has explored the possibility of a Judeo-Christian “ citizenship ” environmental ethic as a more radical alternative to the familiar Judeo-Christian “ stewardship ” environmental ethic that was developed in response to criticism from environmental historians and philosophers.

Additionally, Callicott has been criticized for espousing an overbearing and impolitic monism in environmental ethics.
