Nicomachean Ethics

The *Nicomachean Ethics* is the most famous work on ethics written by the philosopher Aristotle. Ethics is defined here as the science of the good for human life. It investigates the goal or "end" toward which all human actions aim. Unlike pre-Socratic philosophy, which focused on theoretical natural science, Aristotle viewed ethics as a practical discipline. It does not just study what the good is. Instead, it seeks to provide practical help for achieving it. This makes the work a guide for how individuals should best live their lives.

Aristotle’s approach is teleological, meaning it is based on an investigation into the "telos," or end, of a human being. He argues that the final cause of anything is identical to the good of that thing. For humans, the highest good is a state called *eudaimonia*. This Greek term is often translated as "flourishing" or "happiness." To achieve *eudaimonia*, a person must engage in action (*praxis*) that is appropriate to the human soul. This soul must function at its most excellent or virtuous level. An excellent human is someone who lives well, beautifully, and with serious purpose.

To reach this state of flourishing, Aristotle describes a specific sequence of steps involving character development. The process begins with the practice of righteous actions, often under the guidance of teachers. These repeated actions eventually form good habits. These habits then create a stable character, known in Greek as *ethos*. This character is a stable disposition, much like health or knowledge, that must be maintained through effort. Aristotle notes that character involves conscious choice, distinguishing it from simple habit. Through this process, individuals develop moral virtues that allow them to live excellently.

There is significant debate regarding the origin of the book's title. Most scholars assume the name refers to Nicomachus. One theory suggests the work was dedicated to Aristotle's son. Another theory proposes that his son edited the text, though he likely died young. A third possibility is that it was dedicated to Aristotle's father, who was also named Nicomachus. Because the text does not appear to be in a form intended for publication, some believe it consists of lecture notes. These notes were likely meant for students or for use by a lecturer.

The history of the text is a journey of survival and recovery. After Aristotle died in 322 BCE, his writings passed to his successor, Theophrastus. Later, the library moved to Neleus of Scepsis. To prevent the Kingdom of Pergamon from seizing the books, the heirs hid the collection in a cellar. The books remained there for about 150 years in poor conditions. Eventually, the collection was recovered by Apellicon in Athens around 300 BCE. Later, in 86 BCE, the Roman leader Sulla seized the library and moved it to Rome. There, Andronicus of Rhodes organized the texts into a complete edition.

Aristotle's influence on history is vast and measurable. During the European Middle Ages, the *Nicomachean Ethics* was a core work of philosophy. Thinkers like Albertus Magnus introduced a synthesis of Aristotelian ethics and Christian theology. Thomas Aquinas developed the most important version of this synthesis. The work remained a main authority at Protestant universities for centuries. In fact, over fifty Protestant commentaries were published before the year 1682. Even during the seventeenth century, thinkers like Francis Bacon and Thomas Hobbes engaged with this tradition, even when arguing against it.

Today, the work continues to shape modern thought through the virtue ethics revival. Contemporary philosophers such as Martha Nussbaum, Alasdair MacIntyre, and G. E. M. Anscombe have renewed interest in these ideas. The text also maintains a deep connection to the field of politics. While ethics focuses on the individual, Aristotle's *Politics* looks at the good of the whole community. He believed that social institutions are necessary to help people become good. Thus, the study of how one person lives is inseparable from the study of how a society is organized.
