The two authors each offer a clear, well-developed opening statement, a direct response to the other’s statement, and then a response to the other’s response. Along the way, they explore central questions, like: What kind of beings matter morally? What kind of obligations do we have towards other animals? How demanding can we reasonably expect these obligations to be? Do our individual consumer choices, such as the choice to purchase factory-farmed animal products, make a difference to the wellbeing of animals? The debate is helpfully framed by introductions and conclusions to each of the major parts and by smaller introductions to each of the sub-sections. A Foreword by Dustin Crummett sets the context for the debate within a larger discussion of sentience, moral standing, reason-guided compassion, and the larger field of animal ethics.
