An Overview of Integral Theory: An All-Inclusive Framework for the 21st Century
By Sean Esbjörn-Hargens

This primer to integral theory provides an up to date introduction and is an ideal piece to give to colleagues and friends who keep asking you "What is 'integral theory'?. For years I have heard people complain that there isn't a solid intro to the AQAL model. While Ken Wilber has penned a few introductions these often aren't viewed as ideal presentations for many professional contexts. My hope is that this new introduction will fill in the gap and allow individuals another resource in communicating the basics of integral theory. This introduction is also written in a way that even seasoned integral practitioners will find illuminating with new details of integral theory being offered.

An Overview of Integral Ecology: A Comprehensive Approach to Today's Complex Planetary Issues
By Sean Esbjörn-Hargens and Michael E. Zimmerman

This primer basically serves as a 15 page summary of our 800+ page book which just came out. So for those of you who want the cliff notes version of Integral Ecology - here it is (but keep in mind that all the juicy endnotes - all 200 pages of them - are only in the book :). Michael and I have intentionally removed any jargon and made this as accessible to a wide audience as possible.

Responding to Climate Change: The Need for an Integral Response
By Karen O'Brien

This primer gives a really great overview of why integral theory is relevant to issues of climate change. Karen outlines 6 ways integral theory contributes towards addressing the complex issue of climate change and then anchors this in the unfolding situation in the Arctic region.

An Ontology of Climate Change: Integral Pluralism and the Enactment of Multiple Objects
By Sean Esbjörn-Hargens

This article offers a more advanced overview of the Integral Ecology framework (particularly the Who x How x What) in it most recent articulation, using climate change as a case study.  Climate change is highlighted as a complex phenomenon that is enacted by multiple methodologies from various disciplines, none of them able to reveal climate change in its entirety.  The ontological status of climate change is explored and the notion of ontological pluralism presented. Next, the role of enactment is explored in the context of climate change. Climate change is the presented as a multiple object with overlapping and divergent dimensions and issues of hybridity and multiplicity are linked to climate change action. Lastly, a framework of Integral Pluralism is presented that addresses the relationship between epistemological distance (the Who), methodological variety (the How), and ontological complexity (the What). In conclusion, this article presents five reasons why it is advantageous—philosophically and pragmatically—to relate to climate change as an ontological plurality.


Interiority Regained - Integral Ecology and Environmental Ethics
By Michael E. Zimmerman

This article serves as a good introduction to integral ecology. Zimmerman explores the importance of including interiors in ecology and environmental ethics.

Humanity, Forest Ecology, and the Future in a British Columbia Valley
By Stephan Martineau

This article provides a valuable case study of integral ecology in action using a local tangible challenge--a 35-year old conflict over land use in the Slocan Valley. The historical and geographical context is presented. Next, the process by which Stephan Martineau worked with different stake-holders and their perspectives is outlined. The inspiring results are then presented.

Integral Ecology, Part 1: Things Are Getting Worse, Getting Better, and Are Already Perfect (MP3)
Sean Esbjörn-Hargens/Michael Zimmerman

There is no shortage of examples of how the environment is compromised by humanity¹s actions. What is less obvious are all of the ways the environment is actually improving. Even less obvious is the recognition that things are perfect just as they are. In this rich introduction to the topic, integral philosopher Ken Wilber joins Sean and Michael as they offer a set of basic considerations to be included in an integral approach to ecology.

Integral Ecology, Part 2: Two Paths to Environmentally-Friendly Behavior (MP3)
Sean Esbjörn-Hargens/Michael Zimmerman

In the second part of this two-part conversation, Sean, Michael, and Ken discuss the important role human consciousness plays in any conversation about ecological issues. Integral ecology recognizes that it is not feasible to focus on environmentally-friendly behavior without also having a conversation about the interiority that provides awareness, meaning, and motivation for such behavior. Discover how to bring the two together in this exciting dialogue.

Integral Ecological Research: Using IMP to Explore Animal Interiors (MP3)
Sean Esbjörn-Hargens

From the emotional brain of an elephant to the sentient eye of a frog, this provocative presentation explores a world where animals are seen for their complexity, beauty and mystery. With a surprising number of ecological disciplines in existence, an integral post-metaphysical framework is arguably needed to adequately describe environmental phenomenon. Join Sean in this lively exploration of the who, what and how of Integral Ecology. This talk was presented at the Integral Theory Conference 2008.

Integral Ecology, Part 1: Uniting Multiple Perspectives on the Natural World (MP3)
Sean Esbjörn-Hargens

Do electrons have shared interiors? In other words, can subjective and intersubjective prehension be traced all the way down? Delve into subtle aspects of 1st, 2nd and 3rd person perspectives as they pertain to humans, animals, and all life. Ken and Sean discuss core contributions of Integral Ecology to the field of ecology, underscoring the novel move to include interior spaces of both humans and animals.

Integral Environmentalism
Michael Zimmerman (Interview with Ross Robertson)

In this engaging exchange, rich with original and stimulating ideas, Michael Zimmerman and WIE?'s Ross Robertson explore the transformations underway in environmentalism today. Out of their conversation, a much fuller and more hopeful vision of sustainable development emerges, one that opens the future to radical change.

The 123 of Gaia
Sean Esbjörn-Hargens

This is a 15-minute guided meditation by Sean Esbjörn-Hargens that was recorded at a three-day Integral Ecology seminar on the University of Colorado Campus in Boulder (March 10-12, 2006 with Barrett Brown). The 123 of Gaia is an awareness practice of Integral Ecology that honors the complexity and depth of the planet by recognizing the sacred dimension of the planet through 1st-, 2nd-, and 3rd-person perspectives. So get into a comfortable position and let this audio clip expand and deepen your awareness. (See Integral Ecology, pp. 335-6 for more details on this practice)

Changing the Way We Pursue the Future: Uniting Multiple Perspectives
Sean Esbjörn-Hargens and John D. Schmidt

The following is a 1 hour interview that appeared on ZOOM’D Leadership with host John D. Schmidt. This show broadly draws upon content of the first four episodes to establish a big picture view of the value of multiple perspectives, and how these perspectives fit together regarding “who is looking at what, how.” The show builds a compelling rationale for why issues can be so conflicted and why so little progress is made. Most approaches to complex issues rely on objective, scientific accounts alone, which are not only partial but often cripple solutions to difficult challenges. The show establishes an explicit frame regarding objective and subjective aspects of reality – the exterior and interior of life. It also builds understanding about the developmental nature of mindsets and how current issues, challenges, and the future itself can be seen from different altitudes among leaders.
