Introduction: Aristotle’s Definition of Happiness

“Happiness depends on ourselves.” More than anybody else, Aristotle enshrines happiness as a central purpose of human life and a goal in itself. As a result he devotes more space to the topic of happiness than any thinker prior to the modern era. Living during the same period as Mencius, but on the other side of the world, he draws some similar conclusions. That is, happiness depends on the cultivation of virtue, though his virtues are somewhat more individualistic than the essentially social virtues of the Confucians. Yet as we shall see, Aristotle was convinced that a genuinely happy life required the fulfillment of a broad range of conditions, including physical as well as mental well-being. In this way he introduced the idea of a science of happiness in the classical sense, in terms of a new field of knowledge.

Essentially, Aristotle argues that virtue is achieved by maintaining the Mean, which is the balance between two excesses. Aristotle’s doctrine of the Mean is reminiscent of Buddha’s Middle Path, but there are intriguing differences. For Aristotle the mean was a method of achieving virtue, but for Buddha the Middle Path referred to a peaceful way of life which negotiated the extremes of harsh asceticism and sensual pleasure seeking. The Middle Path was a minimal requirement for the meditative life, and not the source of virtue in itself.

Aristotle: A Little Background

Aristotle is one of the greatest thinkers in the history of western science and philosophy, making contributions to logic, metaphysics, mathematics, physics, biology, botany, ethics, politics, agriculture, medicine, dance and theatre. He was a student of Plato who in turn studied under Socrates. Although we do not actually possess any of Aristotle’s own writings intended for publication, we have volumes of the lecture notes he delivered for his students; through these Aristotle was to exercise his profound influence through the ages. Indeed, the medieval outlook is sometimes considered to be the “Aristotelian worldview” and St. Thomas Aquinas simply refers to Aristotle as “The Philosopher” as though there were no other.

Aristotle was the first to classify areas of human knowledge into distinct disciplines such as mathematics, biology, and ethics. Some of these classifications are still used today, such as the species-genus system taught in biology classes. He was the first to devise a formal system for reasoning, whereby the validity of an argument is determined by its structure rather than its content. Consider the following syllogism: All men are mortal; Socrates is a man; therefore, Socrates is mortal. Here we can see that as long as the premises are true, the conclusion must also be true, no matter what we substitute for “men or “is mortal.” Aristotle’s brand of logic dominated this area of thought until the rise of modern symbolic logic in the late 19th Century.

Aristotle was the founder of the Lyceum, the first scientific institute, based in Athens, Greece. Along with his teacher Plato, he was one of the strongest advocates of a liberal arts education, which stresses the education of the whole person, including one’s moral character, rather than merely learning a set of skills. According to Aristotle, this view of education is necessary if we are to produce a society of happy as well as productive individuals.

Happiness as the Ultimate Purpose of Human Existence

One of Aristotle’s most influential works is the Nicomachean Ethics, where he presents a theory of happiness that is still relevant today, over 2,300 years later. The key question Aristotle seeks to answer in these lectures is “What is the ultimate purpose of human existence?” What is that end or goal for which we should direct all of our activities? Everywhere we see people seeking pleasure, wealth, and a good reputation. But while each of these has some value, none of them can occupy the place of the chief good for which humanity should aim. To be an ultimate end, an act must be self-sufficient and final, “that which is always desirable in itself and never for the sake of something else” (Nicomachean Ethics, 1097a30-34), and it must be attainable by man. Aristotle claims that nearly everyone would agree that happiness is the end which meets all these requirements. It is easy enough to see that we desire money, pleasure, and honor only because we believe that these goods will make us happy. It seems that all other goods are a means towards obtaining happiness, while happiness is always an end in itself.

The Greek word that usually gets translated as “happiness” is eudaimonia, and like most translations from ancient languages, this can be misleading. The main trouble is that happiness (especially in modern America) is often conceived of as a subjective state of mind, as when one says one is happy when one is enjoying a cool beer on a hot day, or is out “having fun” with one’s friends. For Aristotle, however, happiness is a final end or goal that encompasses the totality of one’s life. It is not something that can be gained or lost in a few hours, like pleasurable sensations. It is more like the ultimate value of your life as lived up to this moment, measuring how well you have lived up to your full potential as a human being. For this reason, one cannot really make any pronouncements about whether one has lived a happy life until it is over, just as we would not say of a football game that it was a “great game” at halftime (indeed we know of many such games that turn out to be blowouts or duds). For the same reason we cannot say that children are happy, any more than we can say that an acorn is a tree, for the potential for a flourishing human life has not yet been realized. As Aristotle says, “for as it is not one swallow or one fine day that makes a spring, so it is not one day or a short time that makes a man blessed and happy.” (Nicomachean Ethics, 1098a18)

The Pursuit of Happiness as the Exercise of Virtue

Aristotle’s doctrine of the mean is well in keeping with ancient ways of thinking which conceived of justice as a state of equilibrium between opposing forces. In the early cosmologies, the Universe is stabilized as a result of the reconciliation between the opposing forces of Chaos and Order. The Greek philosopher Heraclitus conceived of right living as acting in accordance with the Logos, the principle of the harmony of opposites; and Plato defined justice in the soul as the proper balance among its parts.

Similarly with health in the soul: exhibiting too much passion may lead to reckless acts of anger or violence which will be injurious to one’s mental well-being as well as to others; but not showing any passion is a denial of one’s human nature and results in the sickly qualities of morbidity, dullness, and antisocial behavior. The healthy path is the “middle path,” though remember it is not exactly the middle, given that people who are born with extremely passionate natures will have a different mean than those with sullen, dispassionate natures. Aristotle concludes that goodness of character is “a settled condition of the soul which wills or chooses the mean relatively to ourselves, this mean being determined by a rule or whatever we like to call that by which the wise man determines it.” (Nicomachean Ethics, 1006b36)
