Aldo Leopold was a pragmatist in the vernacular sense of the word. Bryan G. Norton claims that Leopold was also heavily influenced by American Pragmatism, a formal school of philosophy. As evidence, Norton offers Leopold's misquotation of a definition of right (as truth) by political economist, A.T. Hadley, who was an admirer of the philosophy of William James. A search of Leopold's digitised literary remains reveals no other evidence that Leopold was directly influenced by any actual American Pragmatist or by (...) Pragmatism (although he may have been indirectly influenced by Pragmatism early in his career). A 1923 reference, by Leopold, to Hadley and Hadley's putative definition of truth, cited by Norton, is dripping with irony. Leopold, as he matured philosophically, regarded a profound cultural shift from anthropocentric dominionism and consumerism to an evolutionary-ecological worldview and an associated non-anthropocentric 'land ethic' to be necessary for successful and sustainable conservation. Hadley espoused a brutal form of Social Darwinism and his philosophy, as expressed in the book of Hadley's that Norton cites, is politically reactionary, militaristic and unconcerned with conservation. Leopold's mature philosophy and Hadley's – far from consonant, as Norton claims – are diametrically opposed. (shrink)

The Anthropocene and the Holocene are coeval. Preserving the Holocene/Anthropocene climate is the overarching concern of twenty-first-century environmental philosophy and ethics. The second wave of the environmental crisis—ozone thinning, biodiversity erosion, and climate change—crested in the mid-1980s and is global in scale. The land ethic is local in scale. Therefore, an earth ethic is needed. Leopold sketched several in 1923: a three-pronged virtue ethic, a care ethic for posterity, an ethic of respect for the living planet. An individualistic ethic for (...) distant future generations falls afoul of the non-identity paradox. Fiduciary care for global civilization can serve as a surrogate. (shrink)

As a conservation policy advocate and practitioner, Leopold was a pragmatist (in the vernacular sense of the word). He was not, however, a member of the school of philosophy known as American Pragmatism, nor was his environmental philosophy informed by any members of that school. Leopold's environmental philosophy was radically non-anthropocentric; he was an intellectual revolutionary and aspired to transform social values and institutions.
