In the previous chapter I gave reasons for believing that the fundamental principle of equality, on which the equality of all human beings rests, is the principle of equal consideration of interests. Only a basic moral principle of this kind can allow us to defend a form of equality which embraces all human beings, with all the differences that exist between them. I shall now contend that while this principle does provide an adequate basis for human equality, it provides a (...) basis which cannot be limited to humans. In other words I shall suggest that, having accepted the principle of equality as a sound moral basis for relations with others of our own species, we are also committed to accepting it as a sound moral basis for relations with those outside our own species - the nonhuman animals.

The article defends ethical vegetarianism, which, for present purposes, is stipulatively taken to be the view that it is morally wrong to eat animals when equally nutritious plant-based foods are available. Several examples are introduced to show that we all agree that animals deserve some direct moral consideration and to help identify and clarify several commonsense moral principles—principles we all accept. These principles are then used to argue that eating animals is morally wrong. Since you no doubt accept these principles, (...) the argument demonstrates that consistency with your own beliefs and values commits you to the immorality of eating meat and requires you to alter your eating behavior accordingly.
