The Basics of Nicomachean Ethics

“The aim of the wise is not to secure pleasure, but to avoid pain.” – Aristotle

Nicomachean Ethics

Aristotle's Nicomachean Ethics is one of the most influential works in Western philosophy, offering a comprehensive examination of virtue, happiness, and the good life. This treatise delves into the nature of ethical behavior, the development of virtuous character, and the pursuit of eudaimonia, or human flourishing. This article explores the historical background, core principles, philosophical depth, modern interpretations, and practical applications of Aristotle's Nicomachean Ethics.

Historical Background | Aristotle’s Life and Times

Aristotle (384-322 BCE) was a Greek philosopher and student of Plato. He founded the Lyceum and was a tutor to Alexander the Great. His works cover a broad range of subjects, including logic, metaphysics, biology, and ethics. Aristotle's ethical theories were a departure from his teacher Plato's ideas, emphasizing practical wisdom and the empirical observation of human behavior.

The Context of Ancient Greek Philosophy: Aristotle's ethical views were influenced by the broader context of Greek philosophy, particularly the works of Plato and Socrates. While Plato emphasized ideal forms and abstract reasoning, Aristotle grounded his philosophy in the practical and observable aspects of human life.

The Influence of Socratic Thought: Socrates’ emphasis on the examined life and the pursuit of virtue deeply influenced Aristotle. However, Aristotle diverged from Socratic thought by focusing on the development of character and the role of habit in ethical behavior.

The Structure of Nicomachean Ethics

The Nicomachean Ethics is divided into ten books, each addressing different aspects of ethical theory and practice. The work is named after Aristotle’s son, Nicomachus, to whom it is traditionally thought to be dedicated.

Book I: The Good for Man: Aristotle begins by discussing the ultimate goal of human life, which he identifies as eudaimonia (often translated as happiness or flourishing). He argues that all human activities aim at some good, and the highest good is eudaimonia.

Book II: Moral Virtue: Aristotle introduces the concept of moral virtue and discusses the doctrine of the mean, which states that virtue lies between two extremes—excess and deficiency.

Books III-V: Specific Virtues: These books examine specific virtues such as courage, temperance, and justice, and explore the role of choice and responsibility in ethical behavior.

Books VI-VII: Intellectual Virtue and Weakness of Will: Aristotle distinguishes between moral and intellectual virtues and discusses the nature of akrasia, or weakness of will.

Books VIII-IX: Friendship: Aristotle devotes significant attention to the nature and importance of friendship in a good life, identifying three types of friendship based on utility, pleasure, and virtue.

Book X: Pleasure and Happiness: The final book discusses the role of pleasure in the good life and concludes with an examination of the contemplative life as the highest form of happiness.

Core Principles


At the heart of Aristotle’s Nicomachean Ethics is the concept of eudaimonia, which can be understood as flourishing or living well. Aristotle argues that eudaimonia is the highest good and the ultimate aim of human life.

The Function Argument: Aristotle’s function argument posits that the good for humans lies in fulfilling their unique function, which he identifies as rational activity. Eudaimonia is achieved by living a life of virtuous rational activity in accordance with reason.

Happiness and Virtue: For Aristotle, eudaimonia is not simply a state of mind but an activity of the soul in accordance with virtue. It involves living in a way that expresses and realizes human potential.

Virtue Ethics

Aristotle’s ethical framework is grounded in the concept of virtue, which he defines as a disposition to act in accordance with reason. Virtue involves both moral and intellectual aspects and is developed through habit and practice.

The Doctrine of the Mean: One of Aristotle’s central ethical principles is the doctrine of the mean, which states that virtue lies between two extremes of excess and deficiency. For example, courage is the mean between recklessness and cowardice.

Moral Virtues: Moral virtues are character traits that are developed through habituation. They include virtues such as courage, temperance, and justice. These virtues enable individuals to act in accordance with reason and achieve eudaimonia.

Intellectual Virtues: Intellectual virtues, such as wisdom and understanding, are developed through education and intellectual engagement. They are essential for making sound judgments and living a rational life.

Practical Wisdom (Phronesis)

Practical wisdom, or phronesis, is a key concept in Aristotle’s ethical theory. It involves the ability to make sound decisions in specific situations by applying general principles of virtue.

Role of Practical Wisdom: Practical wisdom guides individuals in choosing the right means to achieve virtuous ends. It involves deliberation, judgment, and the ability to act appropriately in varying circumstances.

Difference from Theoretical Wisdom: Aristotle distinguishes practical wisdom from theoretical wisdom (sophia), which involves contemplation and the pursuit of knowledge for its own sake. While theoretical wisdom is concerned with universal truths, practical wisdom is concerned with the particulars of human action.

Philosophical Depth

The Human Good

Aristotle’s exploration of the human good is foundational to his ethical theory. He argues that the good life is achieved through the harmonious development and exercise of both moral and intellectual virtues.

The Role of Reason: Reason plays a central role in Aristotle’s conception of the good life. He argues that human beings are rational animals, and their highest good is realized through the exercise of rationality in both thought and action.

The Life of Contemplation: In the final book of the Nicomachean Ethics, Aristotle concludes that the life of contemplation, or the philosophical life, is the highest form of human existence. This life involves the pursuit of knowledge and the exercise of theoretical wisdom, which he believes brings the greatest fulfillment.

The Doctrine of the Mean

The doctrine of the mean is one of Aristotle’s most distinctive contributions to ethical theory. It provides a practical guide for developing virtuous character and making ethical decisions.

Virtue as a Mean: According to Aristotle, every virtue lies between two vices: one of excess and one of deficiency. The virtuous person is able to navigate between these extremes and find the right balance in their actions and emotions.

Application to Specific Virtues: Aristotle applies the doctrine of the mean to specific virtues, such as courage, temperance, and generosity. Each virtue is a mean relative to the individual and the context, requiring practical wisdom to discern and apply.

Critique and Defense: The doctrine of the mean has been critiqued for its potential subjectivity and reliance on individual judgment. However, Aristotle defends it by emphasizing the role of practical wisdom in guiding ethical behavior and the importance of context in moral decision-making.

Friendship and Community

Aristotle’s treatment of friendship in the Nicomachean Ethics highlights the importance of social relationships in the good life. He identifies three types of friendship: those based on utility, pleasure, and virtue.

Friendship of Utility: Friendships based on utility are formed for mutual benefit. These relationships are often short-lived, as they depend on the usefulness of the association.

Friendship of Pleasure: Friendships based on pleasure arise from shared enjoyment and interests. These friendships are also transient, as they rely on the satisfaction of desires.

Friendship of Virtue: The highest form of friendship is based on mutual respect and admiration for each other’s character. These friendships are long-lasting and contribute significantly to eudaimonia, as they involve the mutual pursuit of the good life.

Community and the Polis: Aristotle also emphasizes the role of the community, or polis, in achieving eudaimonia. He argues that humans are inherently social beings, and the polis provides the structure and support necessary for the development of virtue and the realization of the good life.

Criticisms and Counterarguments

Aristotle’s Nicomachean Ethics has faced various criticisms and counterarguments, prompting ongoing philosophical debate.

Cultural Relativism: Some critics argue that Aristotle’s ethics are culturally specific and may not apply universally. They contend that his emphasis on the Greek polis and certain virtues reflects his cultural context. Defenders of Aristotle argue that while specific applications may vary, the underlying principles of virtue and reason have universal relevance.

Elitism: Aristotle’s focus on the life of contemplation and the development of intellectual virtues has been criticized as elitist, suggesting that only a few can achieve the highest form of eudaimonia. Proponents of Aristotle’s ethics argue that while the contemplative life may be ideal, the development of moral virtues is accessible to all individuals.

Gender and Social Inequality: Aristotle’s views on women and slavery reflect the social norms of his time and have been widely criticized. Contemporary interpretations of Aristotle seek to separate his ethical principles from his outdated social views, emphasizing the applicability of his ideas on virtue and reason to all individuals.

Modern Interpretations and Influences

Neo-Aristotelian Ethics

Neo-Aristotelian ethics represents a revival and reinterpretation of Aristotle’s ethical theories in contemporary philosophy. Thinkers like Alasdair MacIntyre and Philippa Foot have drawn on Aristotle’s concepts to address modern ethical issues.

Alasdair MacIntyre: In his seminal work After Virtue, MacIntyre argues that modern moral philosophy has lost its way by abandoning the Aristotelian focus on virtue and community. He advocates for a return to Aristotelian ethics as a means of restoring moral coherence and integrity.

Philippa Foot: Foot’s work in virtue ethics emphasizes the naturalistic basis of moral virtues. She argues that virtues are grounded in human nature and the requirements of human flourishing. Foot’s approach aligns with Aristotle’s view that virtues are essential for living a good life.

Contemporary Applications: Neo-Aristotelian ethics has been applied to various contemporary issues, including bioethics, environmental ethics, and professional ethics. The emphasis on virtue and practical wisdom provides a framework for addressing complex moral dilemmas in diverse contexts.

Positive Psychology

Positive Psychology, a modern field of psychology that focuses on human flourishing and well-being, has been influenced by Aristotle’s Nicomachean Ethics. Researchers and practitioners in Positive Psychology draw on Aristotle’s concepts of virtue and eudaimonia to develop interventions that promote mental health and happiness.

Martin Seligman: Seligman’s PERMA model of well-being (Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment) reflects Aristotelian principles. The model emphasizes the cultivation of strengths and virtues as pathways to a fulfilling life.

Mihaly Csikszentmihalyi: Csikszentmihalyi’s concept of flow, or the state of complete immersion in an activity, aligns with Aristotle’s idea of living in accordance with reason and achieving excellence in one’s pursuits. Flow experiences contribute to eudaimonia by enabling individuals to fully engage their skills and talents.

Character Strengths and Virtues: Positive Psychology’s focus on identifying and nurturing character strengths mirrors Aristotle’s emphasis on the development of moral and intellectual virtues. Programs that promote strengths-based development are grounded in the Aristotelian understanding of virtue and flourishing.

Ethical Leadership and Business Ethics

Aristotle’s Nicomachean Ethics has also influenced contemporary discussions on ethical leadership and business ethics. The principles of virtue and practical wisdom provide a foundation for ethical decision-making in organizational contexts.

Virtue-Based Leadership: Ethical leadership models that emphasize character and virtue draw on Aristotelian principles. Leaders who embody virtues such as honesty, integrity, and fairness are seen as more effective and trustworthy.

Corporate Social Responsibility (CSR): Aristotle’s emphasis on the common good and the role of the community has informed CSR initiatives. Businesses that prioritize ethical practices and contribute to societal well-being align with Aristotelian ethics.

Stakeholder Theory: The stakeholder approach to business ethics, which considers the interests of all stakeholders in decision-making, reflects Aristotle’s focus on the interconnectedness of individuals and the importance of community. Ethical businesses seek to balance the needs and interests of various stakeholders, promoting overall well-being.

Practical Applications

Personal Development and Character Building

Aristotle’s Nicomachean Ethics offers valuable insights for personal development and character building. The cultivation of virtues through habituation and practice is central to achieving eudaimonia.

Developing Moral Virtues: Individuals can apply Aristotle’s principles by consciously developing moral virtues such as courage, temperance, and justice. This involves practicing virtuous actions until they become habitual and integral to one’s character.

Practicing Practical Wisdom: Practical wisdom, or phronesis, can be developed through experience and reflection. Individuals can enhance their decision-making skills by considering the ethical implications of their actions and striving to find the mean in various situations.

Pursuing Intellectual Growth: The cultivation of intellectual virtues such as wisdom and understanding is essential for living a rational and fulfilling life. Lifelong learning and the pursuit of knowledge contribute to personal growth and eudaimonia.

Education and Character Education

Aristotle’s emphasis on virtue and character development has significant implications for education. Character education programs that promote moral and intellectual virtues align with Aristotelian principles.

Character Education Programs: Schools and educational institutions can implement character education programs that teach students the importance of virtues and ethical behavior. These programs foster a culture of respect, responsibility, and integrity.

Liberal Arts Education: A liberal arts education that emphasizes critical thinking, ethical reasoning, and the pursuit of knowledge reflects Aristotelian ideals. Such an education prepares students to live fulfilling and virtuous lives.

Mentorship and Role Models: Aristotle’s emphasis on the importance of role models for developing virtue can be applied in educational settings. Teachers and mentors who exemplify virtuous behavior provide valuable guidance and inspiration for students.

Community Building and Civic Engagement

Aristotle’s Nicomachean Ethics highlights the importance of community and civic engagement in achieving eudaimonia. Active participation in community life and the pursuit of the common good are essential for personal and societal well-being.

Civic Responsibility: Individuals can apply Aristotle’s principles by actively participating in civic life and contributing to the well-being of their communities. This involves volunteering, voting, and engaging in community initiatives.

Building Inclusive Communities: Aristotle’s emphasis on the interconnectedness of individuals supports the creation of inclusive and supportive communities. Efforts to promote diversity, equity, and inclusion align with Aristotelian ethics.

Social and Environmental Responsibility: The principles of Aristotle’s ethics can be applied to promote social and environmental responsibility. Ethical behavior that considers the impact on society and the environment contributes to the common good and aligns with the pursuit of eudaimonia.


Aristotle’s Nicomachean Ethics offers a comprehensive and enduring framework for understanding virtue, happiness, and the good life. Its emphasis on eudaimonia, virtue, and practical wisdom provides valuable insights for personal development, ethical behavior, and community building.

The ongoing relevance of Aristotle’s ethical theories in contemporary philosophy, psychology, education, and leadership highlights their significance. As we continue to explore the nature of the good life and human flourishing, Aristotle’s Nicomachean Ethics remains a foundational text that offers timeless guidance for living a virtuous and fulfilling life.
