In August 1964 a thirty-six-year-old Canadian from a famous family--one who has already joined the navy during war at age thirteen, become an officer, earned a PhD, and taught ethics at the University of Toronto--takes up residence in a little house he just bought in the village of Trosly, France, with two mentally disabled men he has removed from a care home. The house, which he calls l'Arche (the Ark), has neither water nor electricity. His plan? None. He is just convinced he has to do it, touched by the silent cry of these men shut up in the gloomy, violent institution where he found them. His example is contagious; within months the community has grown to over fifty. Jean Vanier is known and loved around the world for having created L'Arche, those unique communities of people with disabilities and their volunteer caregivers in more than one hundred and fifty sites on five continents. But Vanier is also a philosopher, a spiritual master who touches believers and nonbelievers alike, a tireless messenger of peace and ecumenism, and an adventurer with life full of twists and turns. This biography paints a portrait of this man and the events and influences that shaped his destiny.
