Thomas Berry (1914-2009) was a priest, a 'geologian, ' a historian of religions, and a philosopher. He was an early and significant Catholic voice awakening religious sensibilities to the environmental crisis. He is particularly well-known for articulating a 'universe story' that explores the world-changing implications of the new cosmology. Berry pointed the way to an ecological spirituality attuned to our place in nature and giving rise to an ethic of responsibility and care for Earth. This work, makring the centenary of his birth, offers an invaluable guide to one of the true prophets and spiritual masters of our time
