The Essence of Plato’s Euthyphro: Summary, Themes and Famous Notions

Plato’s Euthyphro is a poignant exploration of the interplay between piety, morality and the relationship between the divine realm and human affairs. It pertains to Plato’s early dialogues, characterized by their focus on Socrates and his distinct methodology – a reasoned dialectic approach, known as elenchus – and distinct ethical concerns, as well as the search for universal truths.

In the Euthyphro, Plato brings to the forefront central questions that have intrigued philosophers and theologians for centuries: What constitutes a moral action? How do we determine what is virtuous or condemnable? Is morality rooted in divine will or is there an objective moral standard that exists independently, and even the gods adhere to?

These queries not only reflect the concerns of the ancient world but also formed the basis for secular thought, moral objectivity and a reasoned approach to ethics in subsequent philosophical and theological traditions. Plato’s portrayal of the Socratic method exemplifies a logical approach to ethics, as Socrates encourages Euthyphro to examine his beliefs and justify them through rational argumentation. This approach foreshadows the later development of ethical systems grounded in reason, such as Kantian ethics and utilitarianism, where moral principles are derived through rational deliberation.

Plato’s Euthyphro is not only a product of its time, addressing the religious and philosophical concerns of ancient Athens, but also lays the philosophical groundwork for the application of reason to morality and ethics.

Background Information

In the context of Athenian society, religion played a central role. The gods and their rituals were deeply intertwined with daily life, ethics and even the functioning of the legal system.

Ancient Athens was a polytheistic society, meaning it believed in and worshipped multiple gods and goddesses. The pantheon of Greek gods included figures like Zeus, Athena, Apollo, and Hera, who were seen as not only powerful but also actively involved in the lives of humans. Religious themes and myths were a common subject in Athenian art, literature and drama. The works of playwrights like Aeschylus, Sophocles and Euripides frequently explored mythological narratives and the relationship between mortals and the gods.

Religion provided the ethical framework for Athenian society, asthe gods were believed to be the ultimate arbiters of what was morally right or wrong. Therefore, ethical behavior was inextricably intertwined with religious piety. Virtuous actions were often seen as those that pleased the gods, while immoral actions were considered those that offended them. The concept of blasphemy, or impiety, which involved disrespecting the gods, was a serious offense that could lead to legal consequences.

The Euthyphro is believed to have been written between 399 and 395 BCE, shortly after Socrates’ trial and execution on charges of impiety and corrupting the youth. The dialogue itself, however, takes place a few weeks prior to Socrates’ trial, when he encounters Euthyphro, a young man who is prosecuting his own father for murder, claiming that his action is just and pious. Socrates engages Euthyphro in a discussion about the nature of piety and its relation to the divine, in an attempt to objectively define morality.

The dialogue raises theological questions about the nature of the gods and their relationship to human affairs, as Socrates’ probing questions challenged conventional religious beliefs by exposing the logical limitations and contradictions in equating morality with divine will.

Synopsis of Plato’s Euthyphro

Plato’s Euthyphro is a philosophical dialogue between two characters, Socrates and Euthyphro, on the nature of piety. More specifically, it is an exploration of the concept of piety, the relationship between morality and the gods, and the intricate interplay between divine authority and ethical principles.

The dialogue takes place in the weeks leading up to Socrates’ trial. Euthyphro, a young man, encounters Socrates outside the courthouse in Athens and informs him that he is at the courthouse to prosecute his father for murder. Socrates, who is set to face charges of impiety, taken aback by Euthyphro’s willingness and confidence in prosecuting his own kin, seizes the opportunity to inquire for a clear and universally applicable definition of piety.

The encounter between Socrates and Euthyphro leads to a conversation about the nature of piety, morality and the gods. The dialogue progresses through a series of back-and-forth exchanges as Socrates employs his trademark Socratic method. Euthyphro initially believes he knows the nature of piety and why his actions are just. However, as the dialogue unfolds, he becomes increasingly challenged by Socrates’ inquiries. Euthyphro offers multiple definitions of piety, each subject to Socratic scrutiny.

Initially, he suggests that prosecuting a wrongdoer, even if the wrongdoer is a family member, constitutes piety. Socrates, however, responds that this is an example of piety rather than a definition.

Euthyphro’s next proposal asserts that piety is what pleases the gods. While Socrates finds this definition more general, he raises the issue of conflicting divine opinions – as the gods are numerous, as are their personalities and preferences, and thus may not agree – leading to the logical inconsistency of an action being both pious and impious simultaneously.

Euthyphro’s third definition claims that piety is what all the gods love and what all the gods hate is impious. Socrates’ response became known as the famed Euthyphro dilemma: Is an action pious because the gods love it, or do the gods love it because it is pious? The first option, suggesting that piety derives from divine preference, raises questions about the arbitrariness of morality. While the second option proposes that there exists an independent standard of piety that the gods recognize, implying that moral principles transcend divine authority.

Euthyphro contends that that which is pious is loved by the gods because it is pious, but Socrates challenges Euthyphro’s assertion, highlighting a circular reasoning that leaves the concept of piety ambiguous.

As the dialogue progresses, Euthyphro attempts to amend his definition by suggesting that piety concerns taking care of the gods. Socrates, however, refutes this by indicating that treating the gods as beneficiaries of human actions may lead to hubris.

Ultimately, Euthyphro finds himself in a conceptual quagmire, unable to provide a satisfactory definition of piety. Socrates suggests that piety might be a subset of justice, yet this proposition fails to distinctly define piety.

In the final stages of the dialogue, Euthyphro presents a fifth and final definition of piety: “Piety is an art of sacrifice and prayer”, explaining that piety involves showing respect and reverence to the gods through acts of devotion. This reinforces the notion that piety is intricately tied to the likes and dislikes of the gods, but once again fails to provide a universal and applicable definition of piety.

Plato’s Euthyphro concludes without a definitive definition of piety, a recurrent theme in the early Platonic dialogues. The open-ended conclusion reflects a broader theme in Socratic philosophy: that wisdom involves the acknowledgment of one’s ignorance, and that the pursuit of truth is a continuous process of refutation and refinement through reasoned dialogue.

Analysis: Main Themes

Plato’s Euthyphro is a rich philosophical work that explores a wide range of themes, from the nature of piety and morality to the complexities of human knowledge. Although primarily focused on the importance of and difficulty in defining virtue in such a way that it may objectively judged and consistently applied – thus becoming a universal ethical standard – several noteworthy themes emerge that collectively contribute to its richness and historical significance.

Universal Ethical Truths

Euthyphro is a classic example of Socratic dialogue, an approach to philosophy in which Socrates poses questions to explore complex notions. Through elenchus, Socrates exposes the difficulty in providing a universal, clear and applicable definition of piety, raising broader questions about the essence of morality and the standard of ethical conduct. This reflects a broader theme in Plato’s works of encouraging a logical approach to knowledge and the search for universal truths.

The Euthyphro highlights the epistemological challenge of arriving at a definitive and universally accepted definition of moral concepts, whilst also encouraging the pursuit of universal truths through reason in the realm of ethics and philosophy.

This pursuit of unquestionable, universal truths, which would later be exemplified in Plato’s theory of forms, is a hallmark of both Socratic and Platonic philosophy.

A Logical Challenge to Religious Ethics

This dialogue presents the famous Euthyphro dilemma, which raises fundamental questions about the relationship between morality and the divine. Socrates asks whether an action is pious because the gods approve of it, or if the gods approve of it because it is inherently pious.

The Euthyphro dilemma has had a profound influence on discussions in ethics and theology throughout history. It highlights the tension between divine command theory, which asserts that moral principles are contingent on the will of the gods, and the concept of objective morality, which suggests that moral truths exist independently of divine commands.

This philosophical problem has spurred extensive debates about the nature of morality, the foundations of ethics and the implications for religious belief systems.

Moral Relativism vs Objective Morality

Although the Euthyphro does not explicitly delve into discussions of moral relativism and objectivity, it indirectly raises questions about these philosophical concepts.

If piety is solely dependent on the approval of the gods, then morality is relative to the character and preferences of various gods, or even different communities that worship different gods. Moral standards, then, vary across cultures and societies, and there is no universally objective moral truth.

On the other hand, if there is some intrinsic, objective quality of piety that the gods recognize, then morality is not subject to individual or societal conventions but grounded in an external, objective truth, which is the basis for definitive and universal ethical claims.

The Euthyphro dilemma, therefore, is a precursor to discussions on the universality of ethics.

The Nature of Virtue

The exchange between Socrates and Euthyphro, although primarily focused on the concept of piety, is also an exploration of the essence of moral virtue itself and the inherent challenges in understanding and defining it. Piety is considered a virtue, and the inquiry into what makes an action pious is, in a broader sense, a question about defining virtuous behavior in such a way that it may be consistently emulated.

The Euthyphro, therefore, is an early exploration of virtue ethics: a branch of moral philosophy that contends that the development of virtuous character traits is the foundation of ethical behavior.

The Famous Euthyphro Dilemma

In the Platonic dialogue Euthyphro, Socrates poses a question that would become famous in its own right, known as the Euthyphro dilemma: Is the pious loved by the gods because it is pious? Or is it pious because it is loved by the gods?”

This seemingly simple question encapsulates a complex dichotomy that delves into the very essence of morality’s origins, and prompts us to consider how philosophy, theology and ethics intersect, encouraging a deeper examination of ethics and its implications for human conduct and beliefs.

If something is deemed morally virtuous because of divine preference, this raises questions about the apparent arbitrary nature of morality; for actions we may view as ethically improper could be labeled virtuous if sanctioned by the gods, and vice versa. Moreover, the complexities of interpreting divine intentions presents considerable hurdles, possibly resulting in ethical paradoxes and potentially encouraging actions that might be considered deeply unethical by human standards, yet justified under divine will. Finally, if we contend that the divine is beyond human comprehension, then morality and ethical principles also become unknowable, and we are left with no objective standard by which to judge right from wrong.

On the other hand, if the gods love that which is inherently moral, then there exists an objective and universal moral standard by which actions and behaviors can be evaluated, independently of the divine. This objective morality would render ethical principles knowable to humans through reason, and therefore subject to reasoned discussion and debate, potentially adaptable and ever-evolving. As a result, discussions involving the gods’ preferences or involvement in ethical matters become largely superfluous, since ethics can be comprehended independently. This perspective shifts the focus towards understanding ethics as an inherent aspect of human existence, through communal discourse guided by reason.

The Euthyphro dilemma, and the perspective it subtly encourages, contributed to the emergence of secular ethics, which asserts that moral principles can be understood and evaluated independently of religious beliefs or divine authority. The idea that morality is grounded in objective and rational principles accessible to human reason, moreover, played a significant role in the emergence of moral realism.

The development of secular ethics and moral realism allowed for ethical discussions to occur within a broader intellectual and philosophical context, separate from religious doctrines. This separation fostered a greater emphasis on rational inquiry, ethical analysis and the examination of moral principles in relation to human nature, social interactions and the well-being of individuals and societies.


The Euthyphro is a thought-provoking work that delves into the nature of piety, morality and the relationship between ethical conduct and the divine. Its open-ended ending, failing to provide a definitive definition of piety, has challenged readers throughout the centuries to part-take and strive for a deeper understanding of morality and ethics.

The dialogue also considers the nature of knowledge and the limits of human understanding, and illustrates the Socratic method of inquiry. Socrates’ relentless questioning exemplifies his broader commitment to the examined life, as he emphasizes the importance of critical self-reflection and the pursuit of wisdom, a theme that runs through many of Plato’s dialogues and has had profound implications in the history and development of epistemology.

The central question, known as the Euthyphro dilemma, is whether an action is pious because it is loved by the gods or if the gods love it because it is pious. This dilemma not only highlights the complexity of defining piety, and in a broader sense virtue, but also raises profound questions about the nature of moral concepts and the relationship between ethics and religion. It remains a work of renown, extensively studied and an essential point of discussion in contemporary philosophy, theology and ethics, illustrating the intellectual richness and enduring relevance of Plato’s Euthyphro.
