In the 5th century BC, Athens became the epicenter of an unprecedented intellectual flourishing. In this context, two groups of thinkers emerged that would profoundly shape Western thought: the sophists and Socrates. The sophists, itinerant masters, taught rhetoric and argumentation aimed at promoting personal and political success. Socrates, in turn, sought a deeper understanding of truth and virtue through philosophical dialogue.

Next, we will explore the similarities and differences between Socrates and the sophists, as well as the impact of their ideas on Greek philosophy.

1. Sophists: Masters of Rhetoric and Relativism

The sophists played an essential role in the civic and intellectual formation of Athenian democracy, despite limited information often coming from their opponents' criticisms. Initially, the term "sophist" derived from sophos (wise) without negative connotation, but philosophers like Plato and Aristotle associated them with manipulative practices, a perception that lasted until the 19th century.

With the democratization of Athens, active participation in public life required civic skills such as rhetoric and oratory. The sophists met this demand by teaching persuasion to young people from the emerging classes of merchants and artisans, preparing them for political success and debates in the Agora. Their ability to teach effective argumentation made them highly sought after by wealthy families, although the traditional aristocracy criticized them severely, believing that civic virtues were innate and not teachable.

Beyond rhetoric, the sophists introduced subjective relativism, absolute skepticism, and conventionalism, challenging traditional conceptions of truth and morality. They argued that truth was relative and dependent on cultural context, while norms and values were human constructs subject to change. This pragmatic approach focused on the persuasive effectiveness of arguments, regardless of their intrinsic validity, promoting public debate as an essential tool for democracy.

Despite criticism, especially from Socrates and Plato, the sophists were fundamental in democratizing political discourse and valuing public debate. Figures like Protagoras and Gorgias stood out for their oratorical abilities and for challenging established concepts, profoundly influencing Greek education and philosophy. The sophistic movement, by emphasizing rhetoric and relativism, left a lasting legacy that continues to influence contemporary Western thought.

Sophistic Relativism

The sophists are recognized for their relativistic approach to knowledge and truth, significantly influencing education and politics in democratic Athens. Despite limited information often coming from criticisms of their opponents, such as Plato and Aristotle, the sophists' contribution to philosophical and educational thought is undeniable.

One of the main characteristics of sophistic thought is relativism. Protagoras of Abdera, for example, synthesized this view by stating that "man is the measure of all things," suggesting that truth is subjective and depends on individual perception. For the sophists, there is no universal and immutable truth; instead, truth varies according to cultural and social context. This perspective held that norms and values are human constructs, adaptable and susceptible to change, reflecting the diversity of customs observed in the ports of Ionia.

The sophists also adopted a skeptical stance regarding the possibility of achieving absolute truth. Gorgias, one of the most notable sophists, argued that "nothing exists; if something exists, it cannot be known; if it can be known, it cannot be communicated." This skepticism reinforced the idea that truth is beyond human capacity to be fully understood or transmitted. As a result, the sophists emphasized the importance of debate and argumentation as essential tools for social interaction and continuous learning.

Although severely criticized by the traditional aristocracy, which saw citizenship and civic virtues as innate and unteachable, the sophists played a crucial role in democratizing political discourse. Their emphasis on persuasion and moral and epistemological relativism transformed Athenian education, promoting a more flexible and adaptable approach to knowledge and values. Figures like Protagoras and Gorgias stood out for challenging traditional conceptions, contributing to a dynamic and pluralistic intellectual environment.

Sophistic relativism, grounded in the subjectivity of truth, skepticism about absolute knowledge, and the conventionalism of social norms, challenged traditional conceptions of truth and morality in Ancient Greece. Despite the criticism received, the sophists were fundamental in forming citizens capable of actively participating in public life, valuing debate and argumentation as pillars of democracy. Their contribution to education and philosophy remains significant, highlighting the importance of rhetoric and critical thinking in intellectual and civic development.


2. Socrates

Socrates, born in Athens around 470 BC, was the son of sculptor Sophroniscus and midwife Phaenarete. Educated in geometry and astronomy by Archelaus, he was also influenced by Anaxagoras's cosmology. He devoted himself entirely to Athens, participating in the Peloponnesian War and important trials, always defending obedience to the city's laws. Condemned to death at 70, his influence endures through the accounts of disciples and contemporaries such as Plato, Xenophon, Aristophanes, and Aristotle.

Socrates' philosophical vocation was born from an experience at the Oracle of Delphi, where he received guidance from his daimon — an inner voice that guided him. Adopting the maxim "Know thyself" as his life's mission, he lived modestly alongside his wife Xanthippe and his children, dedicating himself to dialogue and the relentless pursuit of truth. His dialogues, conducted in public and private spaces, aimed to stimulate critical reflection about oneself and the values that guided life. The purpose of his philosophy was to foster ethical autonomy, enabling individuals to create their own laws and moral norms through reason. Thus, the pursuit of truth was not merely an abstract exercise but a practice with direct impact on human conduct and social organization.

Socrates believed that universal concepts were already present in humans, just waiting to be awakened. This process of bringing innate knowledge to light was called maieutics, or "birth of ideas" — an analogy with his mother's profession of helping women give birth.

Socrates left no writings of his own, and his thought is known mainly through the works of Plato, Xenophon, Aristophanes, and Aristotle. These sources present divergent interpretations, creating the "Socratic problem" of identifying his true personality and ideas. Xenophon portrays him as just and patriotic, while Aristophanes caricatures him as a deceptive sophist. Plato, his most influential disciple, offers a detailed portrait that eventually blends his own ideas with those of Socrates, contributing to a complex image of the philosopher.

Unlike the sophists, who charged for their teachings and focused on practical persuasion, Socrates did not demand payment and used the dialectical method to stimulate self-knowledge and the pursuit of truth.

The Socratic Method and Its Philosophical Implications

Socratic dialogue does not seek to provide immediate answers, but to establish a process of questioning that leads the interlocutor to recognize their own ignorance and, consequently, to seek truth. Socrates rejected superficial and individual opinions, arguing that genuine knowledge can only be achieved by understanding the universal essence of things. For him, human reason, being inherently universal, leads those who use it properly to the same results. Thus, dialogue becomes the central tool for revealing this knowledge, allowing the individual to reach a single truth that guides a virtuous and just life.

Socrates believed that virtue is knowledge and that no one does wrong voluntarily; error is the result of ignorance. The maxim "know thyself" was fundamental to Socrates, seen as a path to wisdom and virtuous life. This self-knowledge promotes continuous reflection on one's actions and values.

Socrates criticized the sophists for their relativism and for teaching rhetorical skills without concern for truth or morality. He argued that persuasion without the pursuit of truth compromises the ethical integrity of discourse.

The Socratic method, therefore, does not offer ready-made answers, but stimulates a process of questioning that leads the interlocutor to recognize their own ignorance and thus open themselves to the pursuit of truth. Socrates rejected superficial and particular opinions, maintaining that true knowledge can only be achieved by understanding the universal essence of things. For him, human reason, being universal, leads all who exercise it correctly to the same results. In this way, dialogue establishes itself as the central tool for manifesting this knowledge, allowing human beings to reach the single truth that guides a virtuous and just life.

Knowledge and Virtue

Socrates postulated that virtue is equivalent to knowledge, maintaining that no one acts maliciously voluntarily; errors are a consequence of ignorance. This view implies that, upon acquiring knowledge, the individual will naturally adopt virtuous behaviors.

The relationship between virtue and knowledge can be illustrated by the analogy with practical skills. For example, the virtue of the shoemaker lies in understanding the purpose of shoes and the competence to produce them properly. In this context, "virtue" does not refer to a moral attribute, but to a specific type of knowledge that involves executing a defined task and achieving a clear objective.

Similarly, when discussing the virtue of living as a human being, as the sophists did, it is necessary to understand the function or purpose of human life, highlighting the need for precise definitions to conceptualize virtue.

Socrates did not directly answer the question of the purpose of human life. Instead, he used the method of elenchus to make his interlocutors aware of the need for this search. This method involves two main stages: first, the recognition of one's own ignorance; second, the collection of examples where the relevant concept applies — such as goodness, beauty, or justice — and the identification of a common quality that constitutes the universal essence of the concept.

For example, when formulating a theory of art, Socrates would begin by admitting his lack of knowledge about what art is. Then, he would analyze widely recognized exemplary works to discern the essential quality that they all share, leading to an understanding of the essence or real nature of art.

However, Socrates believed that this process was not sufficient. For him, true knowledge included both the ability to make distinctions and understand the true nature of things, and the ability to act in accordance with this understanding. These two dimensions are inseparable: seeing the good and doing the good are necessary and sufficient for knowledge of the good. Knowing the purpose and good for human beings and acting according to this purpose constitute a single reality. Thus, "no one errs willingly" — no one chooses to do what they know is not good. When someone acts incorrectly, it results from ignorance, an intellectual error, not a moral failure. The person believes they are acting correctly; if they knew they weren't, they wouldn't do it.

Therefore, the only way to help others is to promote knowledge of what is good for them. This knowledge is achieved through dialectic, a method of investigating "the true nature of things."

3. Sophists vs. Socrates

The philosophy of Socrates and the practice of the sophists present significant differences in their perspectives on education, truth, methods, and purposes. These distinctions reflect opposing approaches regarding the role of philosophy in public life and human development.

1. Objective and Nature of Knowledge

  • Sophists: They were teachers specialized in politics, rhetoric, and practical virtue. Their focus was on preparing individuals to achieve success in debates and political life, teaching persuasive techniques. For the sophists, "truth" was relative, shaped by social contexts and argumentative ability. The main objective was pragmatism and effectiveness, not the pursuit of absolute ethical principles.
  • Socrates: Conversely, Socrates sought the essence of things and believed in the existence of universal, immutable truths accessible through reason. He saw knowledge as an end in itself and a path to virtue, rejecting the relativism and superficiality of sophist discourse.

2. Teaching Method

  • Sophists: They used monologues and rhetorical techniques to transmit structured and previously prepared knowledge. Their classes were directed at practical and immediate results, and they charged for their teachings, considering knowledge a commodity.
  • Socrates: He adopted dialogue as his method, developing what became known as the Socratic method. He asked thought-provoking questions to lead the interlocutor to recognize their ignorance and, from there, seek truth on their own. Socrates did not transmit ready-made knowledge but helped awaken the latent knowledge in the individual. Moreover, he rejected charging for his activity, considering knowledge a universal right.

3. Conception of Truth

  • Sophists: They defended relativism, according to which truth depended on cultural context or argumentative ability. For them, what was considered "true" or "just" varied according to social conventions and individual interests.
  • Socrates: He rejected relativism and sought universal and timeless concepts. For him, truth was not moldable or dependent on external circumstances, but rather accessible through critical reasoning and ethical reflection. His investigation aimed to surpass superficial opinion (doxa) and achieve true knowledge (episteme).

4. Purpose of Philosophy

  • Sophists: They considered philosophy a practical tool for personal and social success, focused on political and material results. What mattered was persuasion, regardless of the validity or morality of the argument presented.
  • Socrates: He saw philosophy as a means to promote virtue and moral well-being. For him, philosophy should transform the individual and society, leading them to justice and harmony. The pursuit of truth and ethics was essential, and philosophy could not be reduced to an instrument of personal interest.

5. Relationship with Education

  • Sophists: They acted as itinerant teachers and charged for their services, making their teaching accessible mainly to the elites. For them, knowledge was a product that could be commercialized.
  • Socrates: He considered education a process of self-discovery and collaboration, based on dialogue and reflection. He believed that knowledge should not be restricted to an elite, but rather free and accessible to all.

Conclusion

The sophists and Socrates represented contrasting approaches in Greek philosophy. While the sophists embraced pragmatism and relativism, focusing on persuasion and individual success, Socrates sought universal and timeless principles, seeing philosophy as a path to virtue, self-transformation, and justice. These fundamental differences about truth, ethics, and the purpose of knowledge continue to resonate in contemporary philosophy.

The interaction between Socrates and the sophists marked a crucial moment in Greek philosophy, confronting different conceptions of knowledge, truth, and education. The sophists emphasized the importance of rhetorical ability, while Socrates proposed a deep reflection on virtue and human nature. This dialogue between opposing perspectives not only enriched the philosophical thought of the time but continues to inspire current debates about ethics, education, and the pursuit of knowledge.
