Abstract
This chapter examines Thoreau’s experiences on Mt. Katahdin, vis-à-vis exposure science and wilderness therapy. A close reading of Thoreau’s account suggests the experience had a profound effect on him, emotionally and philosophically, an effect that is relevant to environmental exposure and eco-vulnerability in the contexts of the COVID-19 pandemic and climate change. Thoreau’s experience on that mountain presented to him an aspect of wilderness antithetical to the romantic, transcendentalist notions he previously held and ultimately led to more nuanced, therapeutic depictions found in works like “Walking” and Walden. That such a reconciliation was possible for Thoreau suggests a privileged insulation from trauma not afforded to many. It also indicates the value of both philosophical contemplation and wilderness therapy to promote psychological resilience and adaptability. The author argues philosophers should begin to engage conceptually and normatively with exposure, vulnerability, and resilience.
