Cardinal Virtues
Prudence, justice, fortitude, temperance — classical Greek and Christian schema.
The Cardinal Virtues are the four foundational virtues — Prudence (practical wisdom, phronesis), Justice (giving each what is due), Fortitude (courage in the face of difficulty, andreia), and Temperance (moderation, sophrosyne) — that ground much of classical Greek and Christian moral thinking. The schema descends from Plato's Republic (Book IV), where these four (with slightly different emphasis) are presented as the virtues of the well-ordered soul and just polis, and was substantially elaborated by Aristotle in the Nicomachean Ethics. The Christian tradition added the Theological Virtues (faith, hope, charity, from 1 Corinthians 13), giving rise to the medieval schema of seven virtues — four cardinal and three theological — with Thomas Aquinas providing the most systematic synthesis (Summa Theologiae IIa-IIae). 'Cardinal' derives from Latin cardo (hinge): these are the virtues on which the moral life hinges. Each cardinal virtue has been substantially elaborated: prudence as the integrative virtue that directs the others toward right action; justice as encompassing both general justice (lawfulness) and particular justice (distributive and commutative); fortitude as both endurance and aggressive courage; temperance as moderation in pleasures, anger, and the desire for honor. The framework remains foundational in virtue ethics, professional ethics (especially in medicine and law), Christian moral theology (Catholic, Eastern Orthodox, and Protestant), and ongoing contemporary work in moral psychology and character education.

Primary use case
Foundational schema in classical and Christian moral philosophy; foundation for virtue ethics tradition; basis for professional ethics in medicine, law, and military traditions; Christian moral theology across denominations; classical and Catholic education; influence on contemporary character-strengths research (VIA classification has substantial overlap); reference framework in moral education.
Common criticisms
- Specific virtue list reflects Greek-Christian cultural specifics and is not universal — Confucian, Buddhist, Hindu, and Islamic ethical traditions identify substantially different cardinal virtues
- the schema's apparent comprehensiveness has been argued to obscure genuinely distinct virtues (e.g., compassion, humility, intellectual virtues) that don't reduce to the four cardinal
- contemporary moral psychology (VIA, Big Five) generates virtue lists empirically that overlap with but don't replicate the classical schema
- the integrative role of prudence has been argued to make the framework circular (the virtuous person knows how to apply the virtues)
- risks essentialism about which virtues 'count'
- tension with care-ethics and feminist critiques that the schema reflects masculine moral concerns
- works better as taxonomy of virtue domains than as algorithm for specific action.
