This dissertation provides a theoretical analysis and examination of the role of imagination in the formation of an environmental ethos. The majority of ethical theories in environmental thought largely neglect the role that imagination plays in both the relationships that humans form with their environment, and the subsequent role that imagination plays in constituting the way that those relationships are understood ethically. To explore the role of imagination in constituting and subsequently projecting such an ethical way of being, this dissertation selectively analyzes the history of imagination in philosophy, cognitive science, and environmental thought. In addition, this dissertation also explores the role that images play in forming collective responses to environmental disasters, and the further role that imagination plays in overcoming the moral motivation gap.

The bedrock of this dissertation is the idea that our patterns of thought, speech, and action can be distilled into two distinct approaches defined by (1) the use of things on one hand and (2) the relation to persons on the other. That first approach is represented in our life with technology and has expanded to the point of omnipresence. Being so ubiquitous, technology largely goes unexamined in the way it functions, the effect it has on us, and the effect it has on our neighbor. In this manner, the technological approach is an over-extension of the manipulation of things to the negation of the relation to persons. As a result, our capacity to relate to persons outside a narrow scope had been atrophied. This work is an attempt at renewing the relational approach within contexts shaped by and shaped for the manipulation of things, i.e., technically minded society. To that end, it is necessary to first explore the work of thinkers who have written on relationality in ways which address the over-extension of the technological approach. The thinkers I have chosen in this endeavor are Martin Buber, Dietrich Bonhoeffer, Dorothy Day, and Ivan Illich, each of whom wrote thoughtfully …

This dissertation provides a philosophical analysis about the influence colonialism had over capitalism's current configuration and how their intricate interplay impacts both the social and the ecological spheres, in both central and peripheral countries. Such analysis draws from the work of José Lutzenberger, a Brazilian environmentalist. The current capitalist economic system tends to disregard the environment, since it would be greatly affected by negative externalities. A negative externality is an economic activity that imposes a negative effect on an unrelated third party. Many negative externalities are related to the environmental consequences of production and consumption. In addition, this dissertation explores the fact that an ecological crisis is also a social crisis. A genealogical and existential thread going from Brazil's early days as one of Portugal's colonies to the present is drawn, showing how colonialism helped to create the foundations and the conditions for the current exploitative capitalist system, in Brazil and elsewhere. To change this situation, the environment should not be entrusted to private interests but to an institution responsible for the good of society as a whole. Genuinely green economies are more prone to appear on the periphery, but only if global economic justice is achieved first.

Farmer suicide is at crisis levels in the United States and India. This crisis is both a problem of experiential knowledge within infrastructure as well as a problem of discourse power. I argue that the logical abstraction required to conceptualize and evaluate farmer suicide cannot be separated from the overall experience of farmer suicide. Rather than existing as distinctly separate phenomena, these elements are co-constitutive. Despite the Centers' for Disease Control identification and designation of farmer suicide as complex, statistically relevant, and elevated, nearly all the policy efforts addressing farmer suicide focus on narrow economic impact and narrow economic relief. While these economic vectors are important, the problem is multifaceted and requires a broadening of policy discourse to include additional factors (e.g. philosophical, existential, psychological, etc.). Using Hannah Arendt's work on politics and the human condition, I connect the conditionality of homo faber (human fabricator/maker), animal laborans (laboring animal), and vita activa (active life) with farmer struggle and suicide. Through the work of Georges Canguilhem and Achille Mbembe, I critique and analyze the predominant discourse and framing of suicide as a disease. Last, but not least, I propose decolonial theory and degrowth theory as viable critical pathways to shift the …
