This book establishes the core question of the text: what is the focused goal of all human action? Aristotle identifies this goal as the good life, or happiness, which he defines as a consistent, active practice of virtue rather than a passive state. Write down how this definition differs from your initial understanding of happiness before reading further.
These books focus on moral virtue, which Aristotle argues is developed through repeated intentional action, not just knowledge. They also explore the role of choice and responsibility in ethical behavior. Use this section to create a list of 3 moral virtues you practice regularly, and note how habit shapes your actions.
Book 4 examines individual moral virtues, while Book 5 explores justice as a virtue that applies to both individuals and communities. Aristotle frames justice as the balance needed to sustain a fair, functional society. Pick one virtue from this section and draft a 1-sentence explanation of how it supports the good life.
Book 6 covers intellectual virtue, including practical wisdom, which guides moral decision-making. Book 7 addresses weakness of will and the struggle to act in line with one’s ethical beliefs. Create a 2-column chart comparing moral and intellectual virtue, with examples from each book.
These books argue that friendship is essential to the good life, as it provides support for practicing virtue and fosters a sense of community. Aristotle categorizes different types of friendship based on their underlying motives. Identify one type of friendship from this section and explain how it aligns with a relationship in your life in a 3-sentence journal entry.
The final book returns to the definition of happiness, identifying contemplation as the highest form of human activity and the closest humans can get to a perfect, sustained state of happiness. This section ties together all prior books’ themes by framing contemplation as the focused expression of intellectual and moral virtue. Write a 1-sentence thesis that links Book 10’s focus to the text’s opening argument in Book 1.
