Philosophers have a long but scattered history of analyzing food. Plato famously details an appropriate diet in Book II of the Republic.
The Roman Stoics, Epicurus and Seneca, as well as Enlightenment philosophers such as Locke, Rousseau, Voltaire, Marx, and Nietzsche, all discuss various aspects of food production and consumption. In the twentieth century, philosophers considered such issues as vegetarianism, agricultural ethics, food rights, biotechnology, and gustatory aesthetics. In the twenty-first century, philosophers continue to address these issues and new ones concerning the globalization of food, the role of technology, and the rights and responsibilities of consumers and producers. Typically, these philosophers call their work “food ethics” or “agricultural ethics.”
