The Limits of Kindness

Abstract

This book is about normative ethics — about what we ought to do and why we ought to do it. The traditional way to approach this subject is to begin by supposing a foundational principle, and then work out its implications. So, for example, consequentialists say that we ought to make the world impersonally better. Kantian deontologists say that we ought to act on universalizable maxims. Contractualists say that we ought to act in accordance with the terms of certain hypothetical contracts. These principles are all grand and controversial. The motivating idea behind this book is that we can tackle some of the most difficult problems in normative ethics by starting with a principle that is humble and uncontroversial. Being moral involves wanting particular other people to be better off. From these innocuous beginnings we are led to surprising conclusions about how we ought to resolve conflicts of interest, whether we ought to create some people rather than others, what we ought to want in an infinite world, when we ought to make sacrifices for the sake of needy strangers, and why we cannot, on pain of irrationality, attribute great importance to the boundaries between people.
