Thoreau's Living Ethics is the first full, rigorous account of Henry Thoreau's ethical philosophy. Focused on Walden but ranging widely across his writings, this study situates Thoreau within a long tradition of ethical thinking in the West, from the ancients to the romantics and on to the present day. It shows Thoreau grappling with important ethical questions that agitated his own society and discusses his value for those seeking to understand contemporary ethical issues. It should be of particular interest to scholars of virtue ethics and environmental ethics.
