Key Concepts

Concept Explanation
Eudaimonia (Human Flourishing) Aristotle believed that the highest good for human beings is eudaimonia, which translates to "human flourishing" or "living well." This is the ultimate aim of life and the basis for evaluating the morality of actions.
Virtue Ethics Aristotle's ethical theory is based on the concept of virtue, which he defines as the golden mean between two extremes. Virtues are acquired through practice and habit, and they allow individuals to live a life of eudaimonia.
Intellectual Virtues Aristotle identified two types of virtues: intellectual virtues (e.g., wisdom, understanding, and practical wisdom) and moral virtues (e.g., courage, temperance, and justice). Intellectual virtues are developed through teaching and experience.
Moral Virtues Moral virtues are acquired through habit and practice, and they govern our actions and emotions. Moral virtues are the mean between two extremes, such as courage being the mean between cowardice and recklessness.
Practical Wisdom (Phronesis) Practical wisdom, or phronesis, is the ability to deliberate well about what is good and beneficial for oneself and others. It combines moral virtue and intellectual virtue, allowing individuals to make wise choices in particular situations.
Role of Reason Aristotle emphasized the role of reason in guiding our actions and emotions. Reason helps us identify the virtuous mean and act accordingly, leading to a life of eudaimonia.
Doctrine of the Mean Aristotle's doctrine of the mean states that virtues are the mean between two extremes of deficiency and excess. For example, courage is the mean between cowardice (deficiency) and recklessness (excess).
