Wisdom as the Greatest of Plato's Four Cardinal Virtues
This essay argues that wisdom is the most important of Plato's four cardinal virtues — wisdom, courage, temperance, and justice. Drawing on Dorothea Frede's overview of Plato's ethics, the paper examines how each virtue corresponds to a class or faculty: wisdom to the rational ruling class, courage to the warrior class, and temperance to self-control across all classes. Justice, understood as the soul's unifying quality, depends on the proper functioning of the other three. Because wisdom enables the ruler and the individual to define the scope and limits of courage, temperance, and justice, the paper concludes that wisdom is the foundational virtue from which the others derive their proper character.

What makes this paper effective
- The thesis is stated immediately and clearly: wisdom is the most important of the four virtues because it determines the role and limits of the other three.
- Each body paragraph is tightly focused on a single virtue, making the comparative argument easy to follow.
- The essay correctly situates each virtue within Plato's class structure (ruling, warrior, and productive classes), grounding the argument in Platonic political philosophy rather than abstract generality.
Key academic technique demonstrated
The paper uses a hierarchical comparative structure: rather than treating the four virtues as equals, it establishes a logical dependency — courage and temperance require wisdom to define their limits, and justice requires all three — then uses this dependency chain as evidence for the thesis. This technique of arguing from functional relationships is a strong model for short philosophical essays.
Structure breakdown
The essay opens with a thesis statement, then briefly surveys the overall structure of the virtues using a cited source. It devotes one paragraph each to wisdom, courage, temperance, and justice before closing with a synthesis paragraph restating how wisdom unifies and governs the others. The single Works Cited entry is correctly formatted in MLA style.
Introduction: The Priority of Wisdom
Of Plato's four cardinal virtues, wisdom may be considered the most important. Though each virtue is important in itself and as part of the whole, wisdom allows the individual to determine the value and role of temperance, courage, and justice.
The Structure of the Four Cardinal Virtues
According to the structure of the virtues, courage determines the "excellence of the spirited part, wisdom belongs to the rational part, and moderation is the consent of all three about who should rule and who should obey" (Frede). Justice is considered to be the "unifying quality of the soul" (Frede). In this respect, justice demands that the other three virtues are equally employed and that no single virtue dominates the others. Justice is understood to exemplify harmony within the soul and the state, whereas injustice is representative of inequality and disorder.
Wisdom and the Ruling Class
Wisdom is the only virtue reserved for the upper, educated classes. It is generally exclusive to the ruling class, whose members determine how their states should be governed. Because the ruling class possesses both the methods and the means for education, their wisdom is derived from intellectual endeavor, and the decisions they make are trusted to be right and virtuous. It is through wisdom that rulers determine what is right and necessary to successfully govern the state. Because wisdom determines the limits of temperance and courage — and, by extension, justice, which is the culmination of the other three virtues — it is the most important of the four.
The concept of the philosopher-ruler is central to Plato's ethics, which holds that only those with genuine knowledge of the Good are fit to govern.
Conclusion: Wisdom as the Foundation
Through the use of wisdom, emotion and impulse are replaced by knowledge and deliberate judgment. Wisdom helps to recognize and assess the functions of the other virtues and employs intellect to define the characteristics and parameters of each. Though every virtue contributes to the whole, it is wisdom that determines what each virtue's contribution is and how that virtue is properly employed.
