Thoreau sought to establish philosophy as a way of life, and to root philosophical, conceptual affairs in more practical or existential concerns. His work provides a sustained meditation on the appropriate conduct of life and the importance of leading our lives with integrity, avoiding what he calls "quiet desperation." The contributors to this volume explore what this American thinker has meant to multiple areas of philosophical inquiry, and why he is still relevant. They show how the imagination, according to Thoreau, might be related to the disclosure of truth; they illuminate the nuances of embodied consciousness and explore the links between moral character and scientific knowledge. They clarify Thoreau's project by locating it in relation to earlier philosophical authors and traditions, noting the ways in which he either anticipated or influenced a host of later thinkers. They explore his aesthetic views, his naturalism, his theory of self, his ethical principles, and his political stances. Most importantly, they show how Thoreau returns philosophy to its roots as the love of wisdom.
