Key ideas in The Nicomachean Ethics
Key idea 1
The highest human good is eudaimonia—flourishing through virtuous activity.
The good of man is the active exercise of his soul's faculties in conformity with excellence or virtue.
Eudaimonia (often translated as "happiness" or "flourishing") is not mere pleasure or satisfaction but the highest human good achieved through excellent activity of the soul according to reason. It requires developing both moral virtues (like courage and generosity) and intellectual virtues (like wisdom and understanding) through habitual practice and rational choice.
Remember
- Understand that true happiness comes from excellent activity, not passive pleasure.
- Cultivate both moral character and intellectual capabilities.
- Recognize that flourishing requires active engagement with life's challenges.
Key idea 2
Virtue is a mean between extremes relative to us.
Virtue is a mean between two vices, one of excess and one of deficiency.
Moral virtues represent the "golden mean" between excess and deficiency. Courage lies between cowardice (deficiency) and recklessness (excess); generosity between stinginess and wastefulness. The mean isn't mathematical but relative to the individual and situation, determined by practical wisdom (phronesis).
Remember
- Look for the appropriate middle ground in moral decisions.
- Develop practical wisdom to determine what constitutes virtue in specific situations.
- Avoid both excessive and deficient responses to challenges.
Key idea 3
We become just by performing just acts, temperate by performing temperate acts.
Men become builders by building, and lyre-players by playing the lyre; so too we become just by doing just acts, temperate by doing temperate acts, brave by doing brave acts.
Virtue develops through habituation—repeated practice of virtuous actions until they become second nature. We don't acquire virtue through theoretical knowledge alone but through consistent practice that shapes our character. This emphasizes the importance of daily choices in moral development.
Remember
- Practice virtuous actions regularly to develop moral character.
- Recognize that ethical development requires consistent effort over time.
- Understand that character is formed through habitual choices, not occasional decisions.
