Core Concepts Recap
Book 2 of Nicomachean Ethics is focused on defining and explaining moral virtue. It draws a clear line between moral virtue, which is built through repeated action, and intellectual virtue, which is learned through instruction. The 'mean' is introduced as the balanced middle ground between extreme behaviors that define each virtue. Write down one example of a virtue you practice regularly and map it to the excess-deficiency-mean framework.
Habit Formation Explained
Aristotle argues that moral virtue is not something people are born with; it is a habit formed through consistent, intentional action. Actions must be chosen deliberately, with awareness of the context and a focus on the good, to build virtue over time. This means that even small, daily choices contribute to the development of moral character. Track one small daily action for a week that aligns with a specific virtue to test this idea.
Context and the 'Mean'
The 'mean' is not a fixed, universal point; it is dependent on the context of the action and the individual. What counts as a balanced action for one person may not be balanced for another, depending on their circumstances, role, and relationships. This flexibility is a key part of Aristotle’s theory, as it recognizes that ethical action must adapt to real-world complexity. Draft a short paragraph explaining how the 'mean' for courage might differ for a soldier and a teacher.
Link to Book 1
Book 2 builds on Book 1’s discussion of the highest human good (eudaimonia, or flourishing). Aristotle frames moral virtue as a critical component of achieving eudaimonia, as it shapes the actions that lead to a well-lived life. This connection ties the theory of virtue to the broader goal of human fulfillment. Write a 2-sentence explanation of how moral virtue supports Aristotle’s definition of eudaimonia.
Common Misconceptions
One common mistake is treating the 'mean' as a strict mathematical average, rather than a context-dependent balance. Another is assuming that any action in the 'mean' is virtuous, regardless of the intent behind it. Aristotle emphasizes that intent and awareness are critical for an action to count as virtuous. Make a note of these misconceptions to avoid them in class discussions and essays.
Modern Applications
Aristotle’s framework can be applied to modern ethical issues, from workplace behavior to personal relationships. For example, the virtue of honesty can be analyzed through the excess (brutal, unkind honesty), deficiency (dishonesty, deception), and mean (tactful, truthful communication). Pick a modern ethical dilemma and apply the excess-deficiency-mean framework to evaluate potential actions. Use this analysis as a talking point in your next class discussion.
