This book recounts more than seven decades of the author’s adventures (and misadventures), interspersed with reflections on the joys and tribulations of membership in the human race. Here are accounts of her travels by bicycle through Africa and the Middle East, and by PMV through the highlands of New Guinea, with asides on the glories of human diversity. The story of her lifelong pursuit of learning, from a one-room schoolhouse in rural France to the halls of MIT, is sprinkled with musings on the problems of learning and teaching. Further, the author pursues her passion for truth and justice from the streets (and jails) of Washington and Boston, to the wilds of Los Angeles.
