Ancient ethical theories, based on the notions of virtue and happiness, have struck many as an attractive alternative to modern theories. But we cannot find out whether this is true until we understand ancient ethics--and to do this we need to examine the basic structure of ancient ethical theory, not just the details of one or two theories. In this book, Annas brings together the results of a wide-ranging study of ancient ethical philosophy and presents it in a way that is easily accessible to anyone with an interest in ancient or modern ethics. She examines the fundamental notions of happiness and virtue, the role of nature in ethical justification and the relation between concern for self and concern for others. Her careful examination of the ancient debates and arguments shows that many widespread assumptions about ancient ethics are quite mistaken. Ancient ethical theories are not egoistic, and do not depend for their acceptance on metaphysical theories of a teleological kind. Most centrally, they are recognizably theories of morality, and the ancient disputes about the place of virtue in happiness can be seen as akin to modern disputes about the demands of morality.

As children, we learn life is unfair: bad things happen to good people and good things happen to bad people. So, it is natural to ask, "Why play fairly in an unfair world? If being immoral will get you what you want and you know you can't get caught, why not do it?" The answers, as argued herein, begin by rejecting the idea that morality and happiness are at odds with one another. From this point of view, we can see how immorality undermines its perpetrator's happiness: self-respect is necessary for happiness, and immorality undermines self-respect. As we see how our self-respect is conditional upon how we respect others, we learn to evaluate and value ourselves, and others, appropriately. The central thesis is the result of combining the ancient Greek conception of happiness (eudaimonia) with a modern conception of self-respect. We become happy, we life the best life we can, only by becoming virtuous: by being as courageous, just, temperate, and wise as can be. These are the virtues of happiness. This book explains why it is bad to be bad and good to be good, and what happens to people's values as their practical rationality develops.

The book examines the major traditions of ancient ethical theory, showing that they share a common theoretical structure. They are examples of eudaimonism, a type of ethical theory in which the basic concepts are those of happiness and virtue.

To be happy is to be emotionally and evaluatively satisfied with one’s life according to a standard of satisfaction one can claim as one’s own as a reasoning being. Since there is no definitive proof of what the standard of satisfaction is, being open to the devising and testing of standards by others is part of claiming one’s own standard as a reasoning being. This open-ness is equivalent to being open to and hence respecting and caring for the pursuit of happiness of others. Since such respect and care is what it is to be moral, it follows that one cannot be happy without being moral.

Happiness and the Christian Moral Life introduces students to Christian Ethics looking at ethics as a path to the "good life" and happiness, rather than a strict set of rules. Revisions and updates include lists of suggested readings and resources, new discussions of how technology shapes relationships, a more fully developed account of Augustine and happiness, and more.

In Human Happiness and Morality, noted philosopher Robert Almeder provides lucid introductory explanations of the major ethical theories and traditions, as well as a clear and comprehensive discussion of the proposed answers to three basic questions in ethics: What makes a right act right? Why should I be moral? What is human happiness and how can I attain it? He then ventures beyond the basic questions, describing the relationship between morality and happiness; clearly defining human happiness; and raising the question of whether happiness, so defined, is the likely product of a life lived morally. In the final chapter, Almeder details simple Stoic rules for happy living and shows how it is possible to live the good life despite the existence of unhappiness and failure in others.

Julia Annas here offers a fundamental reexamination of Plato's ethical thought by investigating the Middle Platonist perspective, which emerged at the end of Plato's own school, the Academy. She highlights the differences between ancient and modern assumptions about Plato's ethics--and stresses the need to be more critical about our own. One of these modern assumptions is the notion that the dialogues record the development of Plato's thought. Annas shows how the Middle Platonists, by contrast, viewed the dialogues as multiple presentations of a single Platonic ethical philosophy, differing in form and purpose but ultimately coherent. They also read Plato's ethics as consistently defending the view that virtue is sufficient for happiness, and see it as converging in its main points with the ethics of the Stoics. Annas goes on to explore the Platonic idea that humankind's final end is "becoming like God"--an idea that is well known among the ancients but virtually ignored in modern interpretations. She also maintains that modern interpretations, beginning in the nineteenth century, have placed undue emphasis on the Republic, and have treated it too much as a political work, whereas the ancients rightly saw it as a continuation of Plato's ethical writings.
