This book has tried to bring out the richness and complexity of the ethical fabric of Sophocles’ plays. Moral issues are not merely motifs, but inform the dramatic structure, and are developed with care and subtlety on the linguistic level. A multiplicity of ethical standpoints is presented in such a way that their implications and practical results are dramatised through choice and argument. While it may be true that an obviously unpleasant character tends to express sentiments contrary to conventional Athenian values, these plays are not melodramas in which only the virtuous command our sympathy and the villains our distaste.

According to Aristotle, character or ethos in tragedy is ’that which reveals what the moral choice is like’. This kind of ethos is what this book explores in Sophocles, by examining five tragedies in which moral choice is central to the course of the drama. These choices are made within the context of traditional Greek morality, which, amongst other things, expected one to help one’s friends and harm one’s enemies. Closely allied to these principles is the conception of justice as retaliation. This nexus of principles provides a pervasive ethical background to most of Greek literature and is of special significance for tragedy.

Antigone is the only character in Sophocles who explicitly purports to value philia above hatred. She does so in the course of a short dialogue, central to the play, which turns on the nature of philia and enmity.

The twin principles Help Friends and Harm Enemies are fundamental to the structure of Oedipus at Colonus. At the outset Oedipus reveals Apollo’s prophecy which he wishes to fulfil, and whose fulfilment will constitute the action of the play. He is to find rest at Athens, ‘bringing profit by dwelling here to those who welcomed me, but doom to those who sent me away, driving me out’). The dual theme is restated more explicitly when he tells the chorus that if they help him they will gain ‘a great saviour for this city, and troubles for my enemies’. For the first 700 lines of the play, until Creon arrives, Oedipus’ two-edged hopes and emerging power to implement them are constantly stressed. He shows his benign aspect to the Athenians, to whom he promises soteria and benefits if they help him. The arrival of Ismene shows his love for his daughters, and through her message his power over Thebes is revealed. It gradually emerges how he intends to use that power, and the scene culminates in a curse on his sons and a prayer that he may indeed have the control over their fate which the oracle has promised him. Later, in his long speech to Theseus, it is made clear that the same event will simultaneously bring help to his friends and harm to his foes, and Theseus’ response shows a full understanding of this.

The opening lines of Ajax are spoken by the goddess Athena, who addresses her favourite, Odysseus, as an adherent of Harm Enemies: he is tracking down an enemy as usual, in a manner worthy of his traditionally tricky persona. She is the dearest of gods to him, and they enjoy a solidarity inherited from the Odyssey. He places himself in her hands, as he has always done in the past. But despite the bond between them, a conflict of values emerges. When Odysseus is reluctant to view the mad Ajax Athena scolds him as a coward. She implies that any kind of fear or ’reluctance’ constitutes cowardice.

Philoctetes is the most ethically complex of all Sophocles’ plays. Philoctetes, Odysseus and the background figure of Achilles present various paradigms for the young Neoptolemus, who must decide in the course of the play which, if any, to adopt as his model. Philoctetes and Odysseus are both endowed with established convictions, but Neoptolemus’ moral character is still in the process of formation. Moral argument and choice take on a peculiarly dynamic role in the plot as we see him exposed to the influence of each of the two older men in turn. Odysseus has come to Lemnos to steal Philoctetes’ invincible bow, which, according to the oracle of Helenus, is necessary for Greek success at Troy. But he knows that Philoctetes hates him bitterly (75f.), so his plan requires the cooperation of Neoptolemus. Odysseus characterises the scheme as a joint one (25), but also makes his own controlling role quite clear. Neoptolemus is to serve (15), and to listen while Odysseus explains his plan (24f.).

Greek popular thought is pervaded by the assumption that one should help one’s friends and harm one’s enemies. These fundamental principles surface continually from Homer onwards and survive well into the Roman period, and indeed to the present day, especially in international relations. They are firmly based on observation of human nature, which yields the conclusion that most human beings do in fact desire to help their friends and harm their enemies, and derive satisfaction from such behaviour. Thus Xenophon’s Socrates can count benefiting friends and defeating enemies as one of the things which bring the ’greatest pleasures’.

Electra presents us with a world in which Help Friends/Harm Enemies remains unquestioned. In the prologue Orestes announces his intention ’to shine out like a star against my enemies’, and when he reappears, declares that he will stop his laughing enemies in their tracks. Electra expresses similar sentiments, and makes loyalty to friends a cardinal principle. Like Orestes, she assumes that their enemies are indulging in hostile mockery. Clytemnestra prays that if her dream is hostile it may recoil on her enemies, and that she may enjoy prosperity with her present friends. The chorus console Electra with the assurance that Orestes is ’noble (esthlos), so as to help his friends’, and their general approval of Electra’s values is clear from their praise and sympathy. When they advise her to moderate her hatred, they are thinking of her welfare, and add that she should not forget it entirely. Neither they nor Chrysothemis, in their efforts to restrain her, maintain that she is wrong in principle. Clytemnestra does suggest that Electra should not treat her philoi as she does (518), but she casts no doubt on Help Friends/Harm Enemies – in fact her criticism of Electra depends on it.
