Book excerpt: Everyone is talking about food. Chefs are celebrities. "Locavore" and "freegan" have earned spots in the dictionary. Popular books and films about food production and consumption are exposing the unintended consequences of the standard American diet. Questions about the principles and values that ought to guide decisions about dinner have become urgent for moral, ecological, and health-related reasons. In Philosophy Comes to Dinner, twelve philosophers—some leading voices, some inspiring new ones—join the conversation, and consider issues ranging from the sustainability of modern agriculture, to consumer complicity in animal exploitation, to the pros and cons of alternative diets.
