In How to be multiple, Helena de Bres – a twin herself – argues that twinhood is a unique lens for examining our place in the world and how we relate to other people. The way we think about twins offers remarkable insights into some of the deepest questions of our existence, from what is a person? to how should we treat one another?Deftly weaving together literary and cultural history, philosophical enquiry and personal experience, de Bres examines such thorny issues as binary thinking, objectification, romantic love and friendship, revealing the limits of our individualistic perspectives. In this illuminating, entertaining book, wittily illustrated by her twin sister, de Bres ultimately suggests that to consider twinhood is to imagine the possibility of a more interconnected, capacious human future.
