As the newly appointed minister of education in Sierra Leone, David Moinina Sengeh assumed that the administration he served—not to mention his family and friends—shared his conviction that all girls belong in the classroom. He was shocked to learn that many of those closest to him, including a member of his own family, were against lifting a long-standing policy banning pregnant girls from school. Radical Inclusion is the dramatic narrative of Sengeh’s drive to guarantee pregnant girls’ right to an education. His story functions as a parable that can help us all advocate for change by reimagining the systems that perpetuate exclusion. The specifics of his efforts in Sierra Leone are captivating, and the lessons Sengeh shares are universal. In addition to the candid account of his quest for reform, he offers stories and perspective from other parts of his life, drawing on his experiences encountering racial profiling as a Harvard student, developing cutting-edge prosthetic limbs at MIT, and working to combat algorithmic bias as a data scientist. Sengeh offers readers a road map for pursuing radical inclusion in their own lives and work—from identifying exclusions, to building coalitions and adapting to a new normal. His book is essential reading for modern leaders or anyone who hopes to help unleash the power of a world that is truly, radically inclusive.
