Philosopher, naturalist, poet and rugged inddividdualist, Henry David Thoreau (1817 - 1862) has inspired generations of readers to think for themselves, to follow the dictates of their own conscience and to make an art of their lives. This book includes five of his most frequently cited and read essays - 'Civil Disobedience,' his most powerful and influential political essay, exalts the law of conscience over civil law. 'Life without Principle' distills the essence of Thoreau's philosophy of self-reliance and individualism. 'Slavery in Massachusetts' is a searing attack on government condonation of slavery. 'A Plea for Captain John Brown' is an eloquent defense of the radical abolicionist, while 'Walking' celebrates the joy of that activity and pleads for conservation of the earth's wild places.
