Taught by America is a book of ‘teachable moments’—those surprising, unanticipated spurts of learning every teacher recognizes as both most authentic and most enduring. Here the most sparkling teachable moments belong to the teacher herself. Powered by idealism, Sarah Sentilles discovers the limits and potential corruption of a savior complex. Struggling to meet the vast needs of her students and their families, she comes to see that an indifferent and hostile system is a form of violence that can undo both good intentions and hard work. Hoping to be of service to the downtrodden, she discovers a deeper and more effective position in solidarity with the oppressed. Sarah Sentilles’s journey contains an injunction: we must change our lives.
