Lecture/Discussion Topics

William James on Nonhuman Nature

At the end of the nineteenth century, when psychology was emerging as a scientific discipline, William James (1842-1910) published his dense text The Principles of Psychology (1890), in which he drew from philosophy, biology, and psychology to explicate his original (and influential) ideas about human self and experience. James's understanding of experience was informed by his appreciation of the natural world. According to biographer, Daniel Bjork (1997), James " found natural settings indispensable to his creative life" and once "attributed creative insight to the natural scene and mood that catalyzed his thinking in an isolated wilderness camp high in the Adirondacks" (p. 67). Bjork tells the story of James's adventures on a scientific expedition in Brazil in 1865 with anti-Darwinian Harvard professor Louis Agassiz. During the expedition, James wrote to his brother from a rainforest glade that he dubbed the "Original Seat of the Garden of Eden,"

I almost thought my enjoyment of nature had entirely departed, but here she strikes such massive and stunning blows as to overwhelm the coarsest apprehension... The bewildering profusion and confusion of vegetation, the inexhaustible variety of its forms and tints... are literally such as you have never dreamt of. [Bjork, 1997, pp. 61-62]

More than thirty years later, and a decade after he published Principles, James (1899) wrote an essay entitled, "On a Certain Blindness in Human Beings." James begins the essay with the statement, "OUR judgments concerning the worth of things, big or little, depend on the feelings the things arouse in us." He goes on to address the lack of empathy humans exhibit regarding the feelings of "creatures and people different from ourselves." He claims that recognizing the connections between all living things is a means to finding significance in life. He refers to the Romantic poets Wordsworth and Shelley and transcendentalists Emerson and Whitman as he makes the argument that rapturous sessions spent reflecting on the natural world are not the waste of time that they might seem when viewed from the abstract perspective of the highly educated class, or when evaluated in terms of commercial value. James claims that by reconnecting with nature on a primal sensory level, humans are able to tap into a profound appreciation of the meaningfulness of all forms of existence,

The remedy under such conditions is to descend to a more profound and primitive level. To be imprisoned or shipwrecked or forced into the army would permanently show the good of life to many an over-educated pessimist. Living in the open air and on the ground, the lop-sided beam of the balance slowly rises to the level line; and the over-sensibilities and insensibilities even themselves out. The good of all the artificial schemes and fevers fades and pales; and that of seeing, smelling, tasting, sleeping, and daring and doing with one's body, grows and grows. The savages and children of nature, to whom we deem ourselves so much superior, certainly are alive where we are often dead.

The Evolutionary Perspective and Environmental Problems

Charles Darwin (1809-1882) and other evolutionary theorists had a significant impact on the field of psychology. In 1909, the journal Psychological Review published four articles commemorating the 50th anniversary of the publication of Darwin's Origin of the Species. James Rowland Angell's essay in the volume, "Darwin's Contribution to Psychology" suggests that Darwin's "radical theories" were easily accepted by psychologists and had a "potent influence" on the functional and genetic approaches in psychology. Angell highlights Darwin's contributions to three primary content areas in psychology: the interaction of instinct and intelligence, the evolution of the "mind of civilized man," and the expression of emotion. The field of psychology witnessed a resurgence in interest in the evolutionary perspective in the 1990.; This revival proved controversial and provocative because some critics saw it as representing a potential return to unpopular ideas such as Social Darwinism, biological determinism, eugenics, and the like. Supporters of the evolutionary perspective suggest that it is progressive, not regressive, in that an acceptance of the fundamental biological nature of human beings and their evolved predispositions will allow us to better understand behavior in all its complexity (e. g., Pinker, 2002). This includes understanding of human behaviors that contribute to environmental problems (e. g., Penn & Mysterud, 2005; van Vugt, Griskevicius, & Schultz, 2014; Wilson, Daly, & Gordon, 1998).

The American Psychological Association hosts a searchable electronic database of important dates in the history of psychology compiled by Professor Warren R. Street. Some of the relevant dates to be found in the database include the following:

Historical Attitudes Toward Animal Research

Donald Dewsbury (1990) describes how the contemporary conflict between animal researchers and animal welfare advocates can be traced back almost 200 years. He describes the Victorian era anti-vivesectionist movement that developed from, and in response to, the humane movement in England that had spurred the creation of the Royal Society for the Prevention of Cruelty to Animals (RSPCA). Similar movements and legislative efforts to restrict animal research arose in the United States shortly thereafter. Dewsbury describes the conflicted position of many British evolutionists, including Charles Darwin, who simultaneously held a deep love for animals and also a strong belief in the benefits of animal research. Darwin was a staunch opponent of animal cruelty but a supporter of vivesection. William James had similarly complex attitudes, referring to vivesection as a "painful duty." Dewsbury provides several examples of researchers and university administrators who were attacked by the media during the antivivisection movement, just as they are today by animal rights advocates; early targets included G. Stanley Hall, John Watson, Ivan Pavlov, and Edward Thorndike. The APA Committee on Animal Experimentation was formed in 1924. Dewsbury suggests that although the animal rights movement today is much broader than the anti-vivesection movement of the latter 19th and early 20th centuries, the criticisms voiced by animal advocates are very similar: animal research is unnecessary because alternatives are available, animal research involves pain and suffering, and animal researchers are more concerned about career ambitions than animal welfare. In both time periods, scientists have argued against these claims. See Baldwin (1993) and Bowd and Shapiro (1993) for essays for and against animal research in psychology. See Saucier & Cain (2006) and Knight, Vrij, Bard, & Brandon (2009) for research on the roots of attitudes about animal research.

B. F. Skinner on Environmental Degradation

In 1982, B. F. Skinner gave a presentation to the American Psychological Association entitled, " Why we are not acting to save the world. " The talk was published in his1987 book Upon Further Reflection. As students learn about Skinner and behaviorism, instructors can include information about Skinner's take on the environmental crisis. In his talk Skinner criticized efforts of environmental (and other) social activist groups as not consistent with operant learning principles.

Many organizations are dedicated to the prevention of nuclear war, overpopulation, and the exhaustion and destruction of a livable environment, but their protests are necessarily directed toward governments, religions and economic systems, and there they stop. Moreover, the principal modus operandi of these organizations is to frighten people, rather than offer them a world to which they will turn because of the reinforcing consequences of doing so (Skinner, 1987, p. 13).

Skinner titled his 1948 utopian novel about a world based on behaviorist priniciples, Walden Two, after transcendentalist nature writer Henry David Thoreau's (1854) Walden; or, Life in the Woods , an autobiographical account of his two-year experiment in "simple living." Students may be interested in visiting the websites of two intentional communities inspired by Skinner's novel: Twin Oaks in Virginia and Los Horcones in Sonora, Mexico.

Establishment of American Psychological Association Division 34 (Society for Environmental, Population, and Conservation Psychology)

Division 34 of the American Psychological Association is also known as the Society for Environmental, Population, and Conservation Psychology (SEPCP). The APA Council of Representatives admitted Division 34 on August 30, 1973. At that time, and for three decades after, it was called "Population & Environmental Psychology." The name was changed in 2011 to reflect the growing field of psychology applied to environmental sustainability. In addition to environmental, population, and conservation psychologists, SEPCP members include ecopsychologists (see next topic). For the early history of Division 34, see Richards (2000). For current news and events, visit the division's website.

The Intellectual Roots Of Ecopsychology

"Matter in the wrong place is dirt. People got dirty through too much civilization. Whenever we touch nature, we get clean."- Carl Jung

Ecopsychology emerged in the early 1990s as a theoretical perspective and applied approach focused on the psychological implications of the bond between humans and nonhuman nature. A fundamental tenet among ecopsychologists is that the disconnect between humans and nonhuman nature that is typical in modern industrial cultures is unhealthy for humans and, subsequently, harmful to the planet. For overviews of ecopsychology, see Schroll (2003), Fisher (2002), Scull (1999), and Boston (1996). Ecopsychology is a rich topic to address in a history course because it is an example of what can happen when scholars within our discipline are inspired to break out of the dominant paradigms and infuse their work with ideas from other intellectual and cultural traditions. Ecopsychological theory and practice is informed by philosophical perspectives such as deep ecology and phenomenology, spiritual traditions such as Buddhism, the transcendental writings of authors such as Thoreau and Emerson, and the life practices of indigenous cultures around the world. Within the discipline of psychology, the first generation ecopsychologists connected primarily with the work of Carl Jung (e. g., Aizenstat, 1995; Sabini, 2002; Yunt, 2001), Gestalt psychology (e. g., Cahalan, 1995; Swanson, 1995 ), and the Humanist and Transpersonal traditions (e.g., Davis, 1998; Kuhn, 2001; Reser, 1995). Today there are some empricists among the ranks of ecopsychologists. Their work can be found in the journals Ecopsychology and European Journal of Ecopsychology.

Future Directions: Conservation Psychology

Contemporary developments in psychology will be tomorrow's history of psychology. Students of psychology history benefit from considering the future trajectories of the field. One such development is the emergence of Conservation Psychology (CP). Carol Saunders's (2003) pioneering paper on CP, and the numerous responses that followed it in a special issue of Human Ecology Review, brought up many interesting questions about what shape this discipline might take. Questions included whether the discipline would reside within psychology or would be a multi-disciplinary endeavor that includes psychology. These questions are not yet resolved. Conservation Psychology was addressed in the July/August 2005 issue of the APA's Monitor on Psychology ("A closer look at Division 34: The call of the wild"), and in 2011, APA Division 34 added "Conservation Psychology" to its name.
