Amartya Sen's memoir, Home in the World, is a compelling read, giving a fascinating view of the making of the mind of one of the foremost public intellectuals of our time. In reflections on the first three decades of his life—all filled with an amazing range of experiences, encounters, and intellectual explorations that span Asia, Europe, and North America—Sen weaves a comprehensive and interlocking narrative that brings together a unitary worldview where two multi-dimensional themes are juxtaposed throughout the book: the presence of the past and the convergence of the near and the far. In this essay, I highlight some of the life experiences and lessons shared in Sen's memoir grounded in his ideas of identity and shared humanity. These ideas took on a prominent place in Sen's life, in part, through his educational experience at the innovative school founded by the visionary poet Rabindranath Tagore. I draw on the views of both Sen and Tagore, as discussed in Sen's memoir. These lessons and ideas can help us in appreciating the power of knowledge, the value of education, and the allure of diversity. They can also guide us in our search for a more just world.
