Fans pick 100 books like Ethics Without Principles

There are a lot of great books about metaethics and a lot of great books about reasons, but this book nabs my top recommendation because Smith makes the topics so deceptively easy to get into and start thinking about. This is the book that I wrote my undergraduate senior thesis on that got me into studying and writing about philosophy for a living, and it is also one of the key books that everyone in my generation in my field grew up thinking about and reacting to. It also has a great balance between an overarching project that spans all of the chapters and some pretty self-contained discussions, especially in the earlier chapters, that helps the reader to focus on one question at a time while also getting a glimpse of how philosophical questions can add up to something bigger.

In this book, Korsgaard makes really forceful the question of what it is that gives morality any authority over us. She divides and surveys the space of possible answers to this question, and develops an incredibly ambitious answer that draws extensively on her interpretation of the historical philosopher Immanuel Kant and makes Kant’s own views intelligible in contemporary terms. It nabs my second recommendation not only because it is gripping and relatively easy to get into, but because, like my top recommendation, of the formative role that it has played for so many contemporary philosophers of my generation, for whom it set the standard of what questions needed to be asked and answered, and what the space of tools might be for trying to answer them.

In this book, Horty uses tools that were originally developed in the fields of artificial intelligence and non-monotonic logic in order to develop an explanatory theory of how reasons compete with one another. The main thing that has led contemporary moral philosophers to be so interested in reasons is that they seem to be able to compete. For example, if on the one hand, you promised your friend to keep a secret, that is a reason that counts against telling anyone else, but if the secret is that they are having an affair with the spouse of another of your friends, that is a reason that counts in favor of telling, and to figure out what you should do, it seems like we have to weigh these reasons together to see which one is more important. But very few ethicists have gotten very far in thinking about the distinctive challenges… show more.

Featured prominently in the plot of the NBC comedy The Good Place, Scanlon’s 1998 book covers much more than reasons and metaethics – it offers an ambitious explanatory theory of where our moral obligations to one another come from, and why they have the particular shape that they do – including of why we can’t justify doing terrible things to someone just because it benefits many other people. But in the first two chapters of the book, Scanlon also offers a large range of important and influential arguments about the nature of reasons and their relationship to both desire and value, and those two chapters in their own right merit this book a place on this list, in addition to its many other virtues.

Minimal Morality offers an account of moral pluralism to fit modern pluralistic societies that have competing and diverse values and norms.

As opposed to the other books in the list, the moral theory here starts with assumptions about the moral character of agents; “no moral in, no moral out” (p. 7).

However, the books is relevant to the discussion about the links between rational and moral behavior because it discusses different ways to be moral and offers a way to address moral disagreement, which can shed light on the discussion about how to reconcile rationality with morality.

My introduction to Richard Alexander was a set of compelling words that he wrote in the margin of a draft of one of my early papers on the evolution of altruism: “no, no, no, no.” I had gotten it wrong. 

In The Biology of Moral Systems, Richard Alexander presents an account of how morality evolved in the human species that has proven almost exactly right. The key to understanding morality, he argues, is to view it as a system that evolved to enable individuals who can benefit from cooperating with one another to resolve their conflicts of interest in mutually beneficial ways. 

Alexander explains how the moral systems that have evolved in human societies are structured in ways that enable people to reap the benefits of increasingly indirect systems of reciprocity.  

In The Life You Can Save, Peter Singer makes the case that we can do a tremendous amount of good by donating to high-impact charities. Every year, hundreds of thousands of children die from preventable diseases, and at little cost to ourselves, we can make an enormous positive difference by giving to organizations like the Against Malaria Foundation. 

This is another important contribution to our understanding of Spinoza as a moral philosopher. It is a denser read than the first three books, but fascinating nonetheless for those already with a little Spinoza under their belt. Rather than concentrating on just the latter parts of the Ethics, where most scholars interested in Spinoza’s moral philosophy focus and where we find the mature discussion of the “free person” who lives under the “guidance of reason”, Sangiacomo is especially concerned with the evolution of Spinoza’s moral thought from his earliest writings to his final, uncompleted work. He considers tensions within, and pressures upon, Spinoza’s understanding of the “Supreme Good” and how to achieve it, and the changes that that account consequently undergoes. Sangiacomo’s thesis is thus both historical and philosophical.

Baruch Spinoza was the philosophical flower of the Dutch Golden Age. Bertrand Russell called him the "noblest and most lovable of the great philosophers", and I am certainly not going to disagree. Like many of the innovators of the Golden Age, his ideas still seem fresh. Expelled from his Jewish community in Amsterdam for his ‘heresies’, we now find his conception of God as nature highly congenial. We probably share his dislike of ritual and perhaps aspire to his renunciation of materialism. His advice neither to fear nor to hope when it concerns things we can do nothing about is as good now as it was when it appeared in his most famous work, Ethics, in 1677.

Spinoza’s philosophy is hard to approach in the original – his arguments are rigorously constructed in the style of ancient Greek mathematics proofs. But Steven Nadler, as well as producing a towering biography… show more.

Aristotle is an obligatory milestone in the history of the main idea of my book: all desire the good or the apparent good.

The Nicomachean Ethics also provides a gallery of interesting and puzzling characters: the akratic, who wants the good but, being weak, goes for what they know to be worse; or the outright vicious, who wholeheartedly chooses the bad, but still under the guise of the good, being misled by pleasant associations with the wrong things.
