Collected here in this omnibus edition are Henry David Thoreau's most important works including A Week on the Concord and Merrimack Rivers; The Selected Essays of Henry David Thoreau including Civil Disobedience; and of course Walden. A Week on the Concord and Merrimack Rivers is both a remembrance of an intensely spiritual moment in Henry David Thoreau's life and a memoriam to his older brother who accompanied him on the trip shortly before his death. Full of fascinating literary musings and philosophical speculations this book is a true precursor to Walden.The Selected Essays contains nineteen essays (including Civil Disobedience). Thoreau was one of America's best known and most influential writers. His work has helped shape the American Discourse and had a lasting effect on the environmental movement in America.Walden is one of the best-known non-fiction books ever written by an American. It details Thoreau's sojourn in a cabin near Walden Pond amidst woodland owned by his friend and mentor Ralph Waldo Emerson. Walden was written with expressed seasonal divisions. Thoreau hoped to isolate himself from society in order to gain a more objective understanding of it. Simplicity and self-reliance were Thoreau's other goals and the whole project was inspired by Transcendentalist philosophy. This book is full of fascinating musings and reflections. As pertinent and relevant today as it was when it was first written.
