Free Will and Determinism in Plato's Myth of Er
This paper examines how Plato reconciles free will and determinism in the Myth of Er from the Republic, arguing that while circumstances may be predetermined, individual souls retain the power to choose their responses. The paper analyzes Plato's broader concept of justice as harmony among reason, spirit, and appetite, and compares this with Socrates' obedience to Athenian law in the Crito. It concludes by reflecting on how Platonic justice differs from—yet may ultimately critique—contemporary notions of individual rights and moral responsibility, suggesting that Plato's integrated view remains philosophically relevant today.

What makes this paper effective
- The paper clearly frames a central philosophical tension—free will versus determinism—and consistently returns to it as an organizing thread across the Myth of Er, the Republic, and the Crito.
- The personal reflection in the penultimate section adds rhetorical honesty and invites the reader to evaluate Platonic justice against lived experience rather than treating it as purely abstract.
- Citations are economically deployed, with Cooper, Reid, and Stent each contributing a distinct angle (motivation, moral education, and free will paradoxes), preventing over-reliance on any single source.
Key academic technique demonstrated
The paper uses comparative textual analysis: it reads two Platonic works (the Republic and the Crito) against each other to show how a single philosophical concept—justice as harmony—manifests differently in a mythological narrative versus a dramatic dialogue. This technique allows the writer to draw out nuance within one thinker's corpus rather than simply contrasting opposing philosophers.
Structure breakdown
The essay follows a tightly integrated five-part structure: an introduction that names the central tension; an analysis of the Myth of Er; an extension to Platonic justice in the Republic; a pivot to the Crito; and a comparative section that brings in contemporary justice before closing with a brief conclusion. Each section builds on the previous one, moving from mythological narrative to political philosophy to personal judgment.
Introduction
In the Myth of Er, Plato examines the contrast between free will and determinism, and in doing so sets up his account of the nature of justice. Plato reconciles these concepts and relates them to his broader definition of justice. This paper compares that understanding with the definition of justice Socrates offers in the Crito; in doing so, it reflects on how this worldview aligns with contemporary definitions of justice.
Free Will and Determinism in the Myth of Er
In the Myth of Er, Plato presents a story in which souls choose their next life, suggesting that they are the masters of their own fate. The complication, however, is that this choice is influenced by each soul's previous life experiences—its habits, virtues, vices, attachments, and so on. What the soul has chosen to do before will shape what the soul wants to do next. This might suggest an element of determinism, if the soul is not capable of changing its orientation. But Plato reconciles these concepts by proposing that while our circumstances may be predetermined, how we respond to them depends on our use of free will. We are never bound to act in any given way; we can always choose, even when circumstances seem to foreclose that possibility. This balance between determinism (the hand we are dealt) and free will (how we play that hand) is at the heart of Platonic justice (Reid; Stent).
Platonic Justice and the Soul's Harmony
Plato's definition of justice in the Republic revolves around the idea of harmony and the proper functioning of each part within a whole. In the context of the soul, justice is achieved when reason, spirit, and appetite are in balance—a balance that, according to Cooper, is the secret motivating human action. The Myth of Er develops this idea by illustrating that souls have the autonomy to choose their fate, but that this choice is informed by their inherent nature and past experiences. Whatever one has done with one's life in the past shapes how one will want to choose the next stage. If a soul has spent its time in conflict with a higher moral order, it will not suddenly want to choose a path of alignment with that order. This, at least, is the logic of Plato's thinking. Justice, in this broader sense, involves an alignment between one's choices (free will) and the natural order of the universe (determinism) (Cooper).
Conclusion
Plato's Myth of Er in the Republic does reconcile free will and determinism. The balance he strikes may seem somewhat different from the more deterministic view of justice in the Crito—but the two positions are more alike than first glance may reveal, given the shared emphasis on harmony that runs through both texts. Compared to contemporary views, Plato's philosophy on this matter offers a perspective well worth serious consideration.
