Over the past 75 years, a new canon has emerged. As humans have driven the living planet to the brink of collapse, visionary thinkers around the world have raised their voices to defend it. Their words have endured, becoming the classics that define the environmental movement today. Emphasizing joy in the world, human cooperation and the value of all living things, this selection of Arne Naess's philosophical writings is filled with wit, learning and an intense connection with nature.
