As mentioned in a recent post, I have a new book being published this week, titled The Tango of Ethics: Intuition, Rationality and the Prevention of Suffering. It’s rooted in reflections I’ve had on ethics and value since some of my earliest interactions with EAs ten years ago, and my observation that some specific ways of thinking about ethics that were already mainstream in the EA community could legitimately be challenged. These include common intuitions about notions like  “good”, “bad” and “value” that have been imported into rational arguments about ethics, without necessarily being put into question or analysed more deeply. The project expanded into a broader reflection on ethics and the dance between intuition and rationality that I think is fundamental to ethical thinking and practice.


Some of the claims I make may appear counterintuitive or conflict with beliefs that are strongly held by many others in the EA community. However, I urge people to consider reading the book with an open mind. Over the years that it has taken shape, I’ve continued to reevaluate my arguments and I remain confident that they have merit. Many of the individual ideas aren’t novel, and are even subscribed to by a subset of EAs. But aside from offering some new perspectives, one of my main goals is to offer a more “holistic” way of thinking about ethics that integrates several core ideas, and that is aligned with solid truths about reality, including the content of subjective experience.

My hope is that the book will provoke reflection within the EA community about the foundations of our core values and how we think about “doing good”. Although I defend a form of negative utilitarianism I call “xNU+”, I show that it doesn’t need to lead to nihilism, especially within the framework I propose. It doesn’t negate self-preservation and the search for meaning, caring about the welfare of future sentient beings, or striving to realise an optimistic vision for the future. But I do argue for the importance of preventing intense and especially extreme/unbearable suffering as an essential ethical principle – and by extension, that only a future that encodes and reflects this principle is a reasonable one to try to preserve.

The book is available in paperback and e-book from Amazon (UKUS, Germany...), B&N, and also directly from the publisher in the UK (paperback only).

 

Description from the publisher’s page

Despite existing for thousands of years, the field of ethics remains strongly influenced by several largely unquestioned assumptions and cognitive biases that can dramatically affect our priorities. The Tango of Ethics: Intuition, Rationality and the Prevention of Suffering proposes a deep, rigorous reassessment of how we think about ethics. Eschewing the traditional language of morality, it places a central emphasis on phenomenological experience and the unique urgency of suffering wherever it occurs, challenges our existence bias and examines the consequences of a metaphysically accurate understanding of personal identity.

A key paradigm in The Tango of Ethics is the conflict and interplay between two fundamentally different ways of seeing and being in the world — that of the intuitive human being who wants to lead a meaningful life and thrive, and that of the detached, rational agent who wants to prevent unbearable suffering from occurring. Leighton aims to reconcile these two stances or motivations within a more holistic framework he labels 'xNU+' that places them at distinct ethical levels. This approach avoids some of the flaws of classical utilitarianism, including the notion that extreme suffering can be formally balanced out by enough bliss, while maintaining a focus on impact. He also identifies some of the limits of rationality and our dependence on intuitions to make ethical decisions.

The book explores the implications of this way of thinking for real-world ethical dilemmas and how we might incorporate it into governance. With societal collapse, increasing totalitarianism and artificial general intelligence all very real threats in the coming years, Leighton argues that it is as important as ever to promote these ethics and their implementation while there is still an opportunity for some convergence around what matters.

 

A few blurbs

“Nearly all of us, philosophers or not, should attach much greater weight to the prevention of severe suffering. This engaging, accessible, and wide-ranging book provides many highly suggestive arguments in support of this claim.”

-Roger Crisp, Professor of Moral Philosophy, University of Oxford

 

“Leighton’s The Tango of Ethics is a well-researched book addressing the most important topic in our universe — the suffering of sentient beings and its implications for ethics, philosophy and technology.”

-Roman V. Yampolskiy, Associate Professor of Computer Science and Engineering, University of Louisville, author of Artificial Superintelligence: A Futuristic Approach

 

“In The Tango of Ethics, Leighton explores the most important question we can ask ourselves: what matters? Questioning old assumptions, he charts a radical yet pragmatic path forward that is consistent both with the constraints of rationality and with our deepest needs and intuitions.”

-Magnus Vinding, co-founder of the Center for Reducing Suffering, author of Suffering-Focused Ethics and Reasoned Politics
