Plato vs. Utilitarians: Conceptions of the Good Life

~4 min read 4 sections Philosophy · Plato Aristotle
Abstract

This essay contrasts Plato's and John Stuart Mill's conceptions of the good life. Drawing on Plato's Euthyphro dialogue and Mill's On Liberty, the paper argues that Plato grounds the good life in objective, transcendental values aligned with the divine will, while Mill's utilitarianism defines goodness subjectively through individual happiness and the avoidance of pain. The essay uses the character of Euthyphro to illustrate the dangers of subjective moral reasoning, arguing that those who make truth conform to their own will—rather than submitting their will to universal truth—ultimately undermine genuine happiness and live in self-deception.

Key Takeaways
  • Introduction: Two Visions of the Good Life: Contrasts Plato's objective and Mill's subjective conceptions
  • Plato's Objective Standard and the Euthyphro Problem: Euthyphro dialogue illustrates failure of subjective morality
  • Mill's Utilitarianism and Subjective Truth: Mill's On Liberty linked to Euthyphro's self-serving reasoning
  • Conclusion: Subjectivity, Self-Deception, and True Happiness: Platonic submission to truth versus utilitarian self-deception

What makes this paper effective

  • The paper grounds its philosophical comparison in a concrete textual example—the Euthyphro dialogue—giving abstract arguments about subjectivity vs. objectivity a vivid, illustrative anchor.
  • It maintains a clear, consistent argumentative thread: Platonic objectivism is positioned as the corrective to utilitarian subjectivism, and every paragraph advances this contrast.
  • The use of direct quotation from Mill's On Liberty strengthens the paper's engagement with primary sources and prevents the comparison from becoming purely abstract.

Key academic technique demonstrated

The paper demonstrates dialectical comparison: rather than treating each thinker in isolation, it weaves them together so that each illuminates the other's weaknesses. Euthyphro functions as a rhetorical bridge—simultaneously a character in Plato's dialogue and a stand-in for the utilitarian position—which allows the student to critique Mill through Plato's own argumentative method.

Structure breakdown

The essay opens by stating the central contrast between Plato and Mill, then introduces Plato's Socratic standard of objective moral truth. The second major movement uses the Euthyphro dialogue to dramatize the failure of subjective moral reasoning. The third movement brings Mill's On Liberty directly into this framework, arguing that Mill's defense of individual judgment mirrors Euthyphro's error. The conclusion synthesizes these threads by arguing that genuine happiness requires submission to universal, objective truth rather than self-determined pleasure.

Introduction: Two Visions of the Good Life

Plato and the Utilitarians do not conceive of the good life in the same manner. Plato, through the character of Socrates, teaches that the true good life can only be attained by dedicating oneself to the pursuit of the one, the good, and the true — the universal transcendental values that, when possessed, make one pleasing to God. Thus, Socrates teaches his students that the way to happiness is to do the will of God, which he argues can be and must be objectively discernible. The Utilitarians, under the direction of the philosopher John Stuart Mill, however, view the good life in a much more subjective way. They hold that what is good is what makes one happy, and what is bad is what makes one unhappy. Pain is the dictator of what is good and bad: if something causes pain, it cannot be good, and if it causes happiness, it must be good.

Because such a rule is subjective — it is up to the individual person to decide, rather than an external standard to which all people can agree — it differs fundamentally in theory from Plato's conception of the good life. Plato says that to be happy one should respect and follow, ultimately, the will of God. The Utilitarians say the opposite: one should respect and follow one's own will, pursuing whatever is perceived to bring happiness. As Plato argues in the Euthyphro, there are many problems with such a view.

Plato's Objective Standard and the Euthyphro Problem

Mill (1859) himself wrote that his philosophy held actions to be "right in proportion as they tend to promote happiness, wrong as they tend to produce the reverse of happiness" — a view very similar to that of Plato's adversary in the Euthyphro. Euthyphro imagines he is in the right when he prosecutes his father for wrongdoing. But Socrates asks Euthyphro what piety is — what is pleasing to the gods — and Euthyphro can only give a subjective answer: piety is what he himself is doing. Socrates then observes that, by this logic, whatever Euthyphro does is good and therefore everyone should imitate him. Euthyphro recognizes the absurdity of this conclusion and is forced to rethink his answer. Yet rather than admit that he may be wrong in prosecuting his father, he chooses not to face the question and rushes off, secure in his ignorance and subjectivity.

Socrates, meanwhile, insists on an objective standard — a universal law that applies to everyone, not one law for Euthyphro and another for Socrates, with each individual determining what is right or wrong. Socrates argues that in such cases the individual sets himself up as judge, when in reality the true judge is God, for God alone stands above everything and is indeed the author of the truth written in human hearts.

Mill's Utilitarianism and Subjective Truth190 words
When Mill (1859) says that people should protect themselves "against the tendency of society to impose…its own ideas and practices as rules of conduct on those who dissent from them" (pp. 13–14), he is speaking precisely about this "subjective truth" that Euthyphro…

Conclusion: Subjectivity, Self-Deception, and True Happiness

Euthyphro and the utilitarians want truth to submit to them. They want truth to conform to their own wills, rather than have to conform their wills to truth. A happiness founded on self-deceit will ultimately lead to a life that falls short of the one, the good, the true, and the beautiful. Failing to live according to those transcendental, universal truths — which are defined for one and all and require objectivity to discern — will in the end lead only to real unhappiness. Plato's vision, as expressed through Socrates, insists that genuine happiness cannot be self-legislated; it must be grounded in something beyond the individual will.
