Socrates (469–399 B.C.), Greek philosopher, the exemplar of the examined life, best known for his dictum that only such a life is worth living. Although he wrote nothing, his thoughts and way of life had a profound impact on many of his contemporaries, and, through Plato’s portrayal of him in his early writings, he became a major source of inspiration and ideas for later generations of philosophers. His daily occupation was adversarial public conversation with anyone willing to argue with him. A man of great intellectual brilliance, moral integrity, personal magnetism, and physical self-command, he challenged the moral complacency of his fellow citizens, and embarrassed them with their inability to answer such questions as What is virtue? – questions that he thought we must answer, if we are to know how best to live our lives. His ideas and personality won him a devoted following among the young, but he was far from universally admired. Formal charges were made against him for refusing to recognize the gods of the city, introducing other new divinities, and corrupting the youth. Tried on a single day before a large jury (500 was a typical size), he was found guilty by a small margin: had thirty jurors voted differently, he would have been acquitted. The punishment selected by the jury was death and was administered by means of poison, probably hemlock.
Why was he brought to trial and convicted? Part of the answer lies in Plato’s Apology, which purports to be the defense Socrates gave at his trial. Here he says that he has for many years been falsely portrayed as someone whose scientific theories dethrone the traditional gods and put natural forces in their place, and as someone who charges a fee for offering private instruction on how to make a weak argument seem strong in the courtroom. This is the picture of Socrates drawn in a play of Aristophanes, the Clouds, first presented in 423. It is unlikely that Aristophanes intended his play as an accurate depiction of Socrates, and the unscrupulous buffoon found in the Clouds would never have won the devotion of so serious a moralist as Plato. Aristophanes drew together the assorted characteristics of various fifth-century thinkers and named this amalgam ‘Socrates’ because the real Socrates was one of several controversial intellectuals of the period. Nonetheless, it is unlikely that the charges against Socrates or Aristophanes’ caricature were entirely without foundation. Both Xenophon’s Memorabilia and Plato’s Euthyphro say that Socrates aroused suspicion because he thought a certain divine sign or voice appeared to him and gave him useful instruction about how to act. By claiming a unique and private source of divine inspiration, Socrates may have been thought to challenge the city’s exclusive control over religious matters. His willingness to disobey the city is admitted in Plato’s Apology, where he says that he would have to disobey a hypothetical order to stop asking his philosophical questions, since he regards them as serving a religious purpose. In the Euthyphro he seeks a rational basis for making sacrifices and performing other services to the gods; but he finds none, and implies that no one else has one. Such a challenge to traditional religious practice could easily have aroused a suspicion of atheism and lent credibility to the formal charges against him. Furthermore, Socrates makes statements in Plato’s early dialogues (and in Xenophon’s Memorabilia) that could easily have offended the political sensibilities of his contemporaries. He holds that only those who have given special study to political matters should make decisions. For politics is a kind of craft, and in all other crafts only those who have shown their mastery are entrusted with public responsibilities. Athens was a democracy in which each citizen had an equal legal right to shape policy, and Socrates’ analogy between the role of an expert in politics and in other crafts may have been seen as a threat to this egalitarianism. Doubts about his political allegiance, though not mentioned in the formal charges against him, could easily have swayed some jurors to vote against him. Socrates is the subject not only of Plato’s early dialogues but also of Xenophon’s Memorabilia, and in many respects their portraits are consistent with each other. But there are also some important differences. In the Memorabilia, Socrates teaches whatever a gentleman needs to know for civic purposes. He is filled with platitudinous advice, and is never perplexed by the questions he raises; e.g., he knows what the virtues are, equating them with obedience to the law. His views are not threatening or controversial, and always receive the assent of his interlocutors. By contrast, Plato’s Socrates presents himself as a perplexed inquirer who knows only that he knows nothing about moral matters. His interlocutors are sometimes annoyed by his questions and threatened by their inability to answer them. And he is sometimes led by force of argument to controversial conclusions. Such a Socrates could easily have made enemies, whereas Xenophon’s Socrates is sometimes too ‘good’ to be true.
But it is important to bear in mind that it is only the early works of Plato that should be read as an accurate depiction of the historical Socrates. Plato’s own theories, as presented in his middle and late dialogues, enter into philosophical terrain that had not been explored by the historical Socrates – even though in the middle (and some of the late) dialogues a figure called Socrates remains the principal speaker. We are told by Aristotle that Socrates confined himself to ethical questions, and that he did not postulate a separate realm of imperceptible and eternal abstract objects called ‘Forms’ or ‘Ideas.’ Although the figure called Socrates affirms the existence of these objects in such Platonic dialogues as the Phaedo and the Republic, Aristotle takes this interlocutor to be a vehicle for Platonic philosophy, and attributes to Socrates only those positions that we find in Plato’s earlier writing, e.g. in the Apology, Charmides, Crito, Euthyphro, Hippias Minor, Hippias Major, Ion, Laches, Lysis, and Protagoras. Socrates focused on moral philosophy almost exclusively; Plato’s attention was also devoted to the study of metaphysics, epistemology, physical theory, mathematics, language, and political philosophy.
When we distinguish the philosophies of Socrates and Plato in this way, we find continuities in their thought – for instance, the questions posed in the early dialogues receive answers in the Republic – but there are important differences. For Socrates, being virtuous is a purely intellectual matter: it simply involves knowing what is good for human beings; once we master this subject, we will act as we should. Because he equates virtue with knowledge, Socrates frequently draws analogies between being virtuous and having mastered any ordinary subject – cooking, building, or geometry, e.g. For mastery of these subjects does not involve a training of the emotions. By contrast, Plato affirms the existence of powerful emotional drives that can deflect us from our own good, if they are not disciplined by reason. He denies Socrates’ assumption that the emotions will not resist reason, once one comes to understand where one’s own good lies. Socrates says in Plato’s Apology that the only knowledge he has is that he knows nothing, but it would be a mistake to infer that he has no convictions about moral matters – convictions arrived at through a difficult process of reasoning. He holds that the unexamined life is not worth living, that it is better to be treated unjustly than to do injustice, that understanding of moral matters is the only unconditional good, that the virtues are all forms of knowledge and cannot be separated from each other, that death is not an evil, that a good person cannot be harmed, that the gods possess the wisdom human beings lack and never act immorally, and so on. He does not accept these propositions as articles of faith, but is prepared to defend any of them; for he can show his interlocutors that their beliefs ought to lead them to accept these conclusions, paradoxical though they may be. Since Socrates can defend his beliefs and has subjected them to intellectual scrutiny, why does he present himself as someone who has no knowledge – excepting the knowledge of his own ignorance? The answer lies in his assumption that it is only a fully accomplished expert in any field who can claim knowledge or wisdom of that field; someone has knowledge of navigational matters, e.g., only if he has mastered the art of sailing, can answer all inquiries about this subject, and can train others to do the same. Judged by this high epistemic standard, Socrates can hardly claim to be a moral expert, for he lacks answers to the questions he raises, and cannot teach others to be virtuous. Though he has examined his moral beliefs and can offer reasons for them – an accomplishment that gives him an overbearing sense of superiority to his contemporaries – he takes himself to be quite distant from the ideal of moral perfection, which would involve a thorough understanding of all moral matters. This keen sense of the moral and intellectual deficiency of all human beings accounts for a great deal of Socrates’ appeal, just as his arrogant disdain for his fellow citizens no doubt contributed to his demise.
