This is a terrific book about affluent individuals' responsibility for addressing global poverty. Gosselin presents three different models of responsibility, each providing a different set of reasoned recommendations. She recognizes that different people will prefer different models but regards the models as complementary rather than mutually exclusive. Gosselin ends the book with her own practical, realistic, and deeply insightful conclusions. The book is philosophically sophisticated, providing a valuable contribution to the scholarship on responsibility. It is also refreshingly crisp, unpretentious, accessible, and briskly paced. It is currently the best available book for introducing students to this important topic.
