The idea of moral progress is a necessary presupposition of action for beings like us. We must believe that moral progress is possible and that it might have been realized in human experience, if we are to be confident that continued human action can have any morally constructive point. I discuss the implications of this truth for moral psychology. I also show that once we understand the complex nature and the complicated social sources of moral progress, we will appreciate why (...) we cannot construct a plausible comprehensive action-guiding theory of moral progress. Yet while the nature and sources of moral progress consistently thwart many theoretical hopes, the idea of moral progress is a plausible, critically important and morally constructive principle of historical interpretation.

My goal in this paper is to shed light on how moral progress actually occurs. I begin by restating a conception of moral progress that I set out in previous work, the “Naïve Conception,” and explain how it comports with various normative and metaethical views. I go on to develop an index of moral progress and show how judgments about moral progress can be made. I then discuss an example of moral progress from the past—the British abolition of the Atlantic (...) slave trade—with a view to what can be learned from this for a contemporary struggle for moral progress: the movement to decarbonize the global economy. I close with some thoughts about how moral progress actually occurs. (shrink)

The twenty-two papers here are invigoratingly diverse, but together tell a unified story about various aspects of the morality of our relationships to animals and to nature.

Traditional conservative arguments against the possibility of moral progress relied on underevidenced assumptions about the limitations of human nature. Contemporary thinkers have attempted to fill this empirical gap in the conservative argument by appealing to evolutionary science. Such “evoconservative” arguments fail because they overstate the explanatory reach of evolutionary theory. We maintain that no adequate evolutionary explanation has been given for important features of human morality, namely cosmopolitan and other “inclusivist” moral commitments. We attribute these evolutionarily anomalous features to a (...) capacity for open-ended normativity, which presents a serious obstacle to theorists who wish to draw substantive moral and political lessons from human evolutionary history.

Of all the things we do and say, most will never be repeated or reproduced. Once in a while, however, an idea or a practice generates a chain of transmission that covers more distance through space and time than any individual person ever could. What makes such transmission chains possible? For two centuries, the dominant view was that humans owe their cultural prosperity to their powers of imitation. In this view, modern cultures exist because the people who carry them are (...) gifted at remembering, storing and reproducing information. How Traditions Live and Die proposes an alternative to this standard view. What makes traditions live is not a general-purpose imitation capacity. Cultural transmission is partial, selective, often unfaithful. Some traditions live on in spite of this, because they tap into widespread and basic cognitive preferences. These attractive traditions spread, not by being better retained or more accurately transferred, but because they are transmitted over and over. This theory is used to shed light on various puzzles of cultural change and to explain the special relation that links the human species to its cultures. Morin combines recent work in cognitive anthropology with new advances in quantitative cultural history, to map and predict the diffusion of traditions. This book is both an introduction and an accessible alternative to contemporary theories of cultural evolution. (shrink)

Ideas about heredity and evolution are undergoing a revolutionary change. New findings in molecular biology challenge the gene-centered version of Darwinian theory according to which adaptation occurs only through natural selection of chance DNA variations. In Evolution in Four Dimensions, Eva Jablonka and Marion Lamb argue that there is more to heredity than genes. They trace four "dimensions" in evolution -- four inheritance systems that play a role in evolution: genetic, epigenetic, behavioral, and symbolic. These systems, they argue, can all (...) provide variations on which natural selection can act. Evolution in Four Dimensions offers a richer, more complex view of evolution than the gene-based, one-dimensional view held by many today. The new synthesis advanced by Jablonka and Lamb makes clear that induced and acquired changes also play a role in evolution.After discussing each of the four inheritance systems in detail, Jablonka and Lamb "put Humpty Dumpty together again" by showing how all of these systems interact. They consider how each may have originated and guided evolutionary history and they discuss the social and philosophical implications of the four-dimensional view of evolution. Each chapter ends with a dialogue in which the authors engage the contrarieties of the fictional "I.M.," or Ifcha Mistabra -- Aramaic for "the opposite conjecture" -- refining their arguments against I.M.'s vigorous counterarguments. The lucid and accessible text is accompanied by artist-physician Anna Zeligowski's lively drawings, which humorously and effectively illustrate the authors' points. (shrink)

How should you live? Should you devote yourself to perfecting a single talent or try to live a balanced life? Should you lighten up and have more fun, or buckle down and try to achieve greatness? Should you try to be a better friend? Should you be self-critical or self-accepting? And how should you decide among the possibilities open to you? Should you consult experts, listen to your parents, or should you do lots of research? Should you make lists of (...) pros and cons, or go with your gut? These are not questions that can be answered in general or in the abstract. Rather, these questions are addressed to the first person point of view, to the perspective each of us occupies when we reflect on how to live without knowing exactly what we're aiming for. To answer them, this book focuses on the process of living one's life from the inside, rather than on defining goals from the outside. Drawing on traditional philosophical sources as well as literature and recent work in social psychology, this book argues that to live well, we need to develop reflective wisdom: to care about things that will sustain us and give us good experiences, to have perspective on our successes and failures, and to be moderately self-aware and cautiously optimistic about human nature. Further, we need to know when to think about our values, character, and choices, and when not to. A crucial part of wisdom, the book maintains, is being able to shift perspectives: to be self-critical; to be realistic; to examine life when reflection is appropriate, but not when we should lose ourselves in experience.

In a sense, all technology is biotechnology: machines interacting with human organisms. Technology is designed to overcome the frailties and limitations of human beings in a state of nature -- to make us faster, stronger, longer-lived, smarter, happier. And all technology raises questions about its real contribution to human welfare: are our lives really better for the existence of the automobile, television, nuclear power? These questions are ethical and political, as well as medical; and they even reach to the philosophical (...) and spiritual. On the whole, we seem pretty well adapted to our technology, at least on the face of it -- but there have always been doubts about whether the human soul thrives best in the oppressively technological world we have created for ourselves. (I am continually struck by how much time I have to spend fixing the machines that supposedly improve my life.). (shrink)
