What is well-being? This is one of humanity's oldest and deepest questions; Valerie Tiberius offers a fresh answer. She argues that our lives go well to the extent that we succeed in what matters to us emotionally, reflectively, and over the long term. So when we want to help others achieve well-being, we should pay attention to their values.

What is human well-being? Valerie Tiberius argues that our lives go well to the extent that we succeed in terms of what matters to us emotionally, reflectively, and over the long term. In other words, well-being consists in fulfilling or realizing our appropriate values over time. In the first half of the book, Tiberius sets out the theory of well-being as value fulfilment. She explains what valuing is and what it is to fulfill values over time. In the second half of the book she applies the theory to the problem of how to help others, particularly our friends. We don't always know how to provide the help we know others need; but we also have the problem of knowing what help they need in the first place, and this is a problem that requires ethical thinking. Tiberius argues that when we want to help others achieve greater well-being, we should pay attention to their values. This entails attending to how others' values fit together, how they understand what it means to succeed in terms of these values, and how things could change for them over time. Being a good and helpful friend, then, requires cultivating some habits of humility that overcome our tendency to think we know what's good for other people without really understanding what it's like to be them.

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, do lots of research? 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, The Reflective Life 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, Tiberius 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, Tiberius maintains, is being able to shift perspectives: to be self-critical when we are prepared for it, but not when it will undermine our success; to be realistic, but not to the extent that we are immobilized by the harsh facts of life; to examine life when reflection is appropriate, but not when we should lose ourselves in experience.

Well-being, happiness and quality of life are now established objects of social and medical research. Does this science produce knowledge that is properly about well-being? What sort of well-being? The definition and measurement of these objects rest on assumptions that are partly normative, partly empirical and partly pragmatic, producing a great diversity of definitions depending on the project and the discipline. This book, written from the perspective of philosophy of science, formulates principles for the responsible production and interpretation of this diverse knowledge. Traditionally, philosophers' goal has been a single concept of well-being and a single theory about what it consists in. But for science this goal is both unlikely and unnecessary. Instead the promise and authority of the science depends on it focusing on the well-being of specific kinds of people in specific contexts. Skeptical arguments notwithstanding, this contextual well-being can be measured in a valid and credible way - but only if scientists broaden their methods to make room for normative considerations and address publicly and inclusively the value-based conflicts that inevitably arise when a measure of well-being is adopted. The science of well-being can be normative, empirical and objective all at once, provided that we line up values to science and science to values.

Science and philosophy study well-being with different but complementary methods. Marry these methods and a new picture emerges: To have well-being is to be "stuck" in a positive cycle of emotions, attitudes, traits and success. This book unites the scientific and philosophical worldviews into a powerful new theory of well-being.

The concept of well-being is one of the oldest and most important topics in philosophy and ethics, going back to ancient Greek philosophy. Following the boom in happiness studies in the last few years it has moved to centre stage, grabbing media headlines and the attention of scientists, psychologists and economists. Yet little is actually known about well-being and it is an idea that is often poorly articulated. The Routledge Handbook of Philosophy of Well-Being provides a comprehensive, outstanding guide and reference source to the key topics and debates in this exciting subject. Comprising over 40 chapters by a team of international contributors, the Handbook is divided into six parts: well-being in the history of philosophy current theories of well-being, including hedonism and perfectionism examples of well-being and its opposites, including friendship and virtue and pain and death theoretical issues, such as well-being and value, harm, identity and well-being and children well-being in moral and political philosophy well-being and related subjects, including law, economics and medicine. Essential reading for students and researchers in ethics and political philosophy, it is also an invaluable resource for those in related disciplines such as psychology, politics and sociology.
