Pericles had many opponents in Athens. Some disapproved of his imperial policy, and others accused him of extravagance in spending so much of the public money on temples. The most serious accusation brought against him was that in beautifying Athens he was spending not only money from the Athenian treasury, but also using that which belonged to the Delian League. This latter accusation was true, and the people called for an ostracism. But it resulted in the support of Pericles by the majority of the Athenians, and in the banishment of his opponent.

Pericles knew what he was doing when he used the money from the treasury of the Delian League. To Athens had been committed the trust of defending the allied islands and cities from Persian aggression and it was the money contributed by the allies for the cost of this defence that was kept in the treasury of the League. Pericles maintained that the beautifying of Athens was a symbol of her might and power, that the great buildings employed labour and encouraged commerce, both of which added to her prosperity, and that these outward signs of her wealth and might added to her ability to protect her allies. He had won for Athens the foremost position in Greece, and he was determined that she should keep it. To this end he argued that Athens was justified in using the money of the League, because the way in which it was being spent added not only to the glory but also to the security of all.

Pericles was also a great lover of all that was beautiful, and he was honestly desirous that the youth of Athens should grow up in a city that should be a joy for ever, that would make them good and useful citizens, and inspire them with an abiding love for and pride in her. But there is a flaw in the character of a man who holds that the end, even if it is a great and glorious one, justifies any means.

Now Attica was very small, and in the days of her prosperity the population of Athens had increased so much that the state could no longer produce enough food to support the people. The far-seeing policy of Themistocles had made Athens stronger on sea than on land, and by the time of Pericles, the salvation of Athens lay in her navy. She was increasing her sea-power in all directions and establishing herself as mistress all over the Aegean and on the shores of the Euxine. This policy was not only dictated by the greed of power, but by the absolute necessity that if Athens were to live, she should control all the trade routes by which corn reached Greece. Without the corn from the shores of the Euxine, Athens would starve.

Sparta was a great land power, and at first this increasing sea-power of Athens did not touch her very closely, but it did affect Corinth, the next sea-power in Greece after Athens. As long as Athens confined her interests to the Aegean and the East, Corinth was not alarmed, but when the Athenians turned to the West and showed their intention of establishing their power there, the Corinthians became seriously alarmed, for this threatened their interests in Sicily and the South of Italy. Corinth had always been hostile to Athens, and she now appealed to Sparta, asking for help to crush Athens. Corinthian envoys went to Sparta, and in a powerful speech one of them set forth the grievances of the Greek world against Athens, representing her power, and entreating the Spartans to lay aside their policy of inaction and to join with them in crushing the Tyrant state.

"Time after time we have warned you of the mischief which the Athenians would do to us, but instead of taking our words to heart, you chose to suspect that we only spoke from interested motives. If the crimes which the Athenians are committing against Hellas were being done in a corner, then you might be ignorant, and we should have to inform you of them: but now, what need of many words? Some of us, as you see, have been already enslaved; they are at this moment intriguing against others, notably against allies of ours; and long ago they had made all their preparations in expectation of war.... And you have never considered what manner of men are these Athenians with whom you will have to fight, and how utterly unlike yourselves. They are revolutionary, equally quick in the conception and in the execution of every new plan; while you are conservative, careful only to keep what you have, originating nothing, and not acting even when action is most necessary. They are bold beyond their strength; they run risks which prudence would condemn; and in the midst of misfortune they are full of hope. Whereas it is your nature, though strong, to act feebly; when your plans are most prudent, to distrust them; and when calamities come upon you, to think that you will never be delivered from them. They are impetuous, and you are dilatory; they are always abroad, and you are always at home. For they hope to gain something by leaving their homes; but you are afraid that any new enterprise may imperil what you have already. When conquerors, they pursue their victory to the utmost; when defeated, they fall back the least. Their bodies they devote to their country as though they belonged to other men; their true self is their mind, which is most truly their own when employed in her service. When they do not carry out an intention which they have formed, they seem to have sustained a personal bereavement; when an enterprise succeeds, they have gained a mere instalment of what is to come; but if they fail, they at once conceive new hopes and so fill up the void. With them alone to hope is to have, for they lose not a moment in the execution of an idea. This is the life-long task, full of danger and toil, which they are always imposing upon themselves. None enjoy their good things less, because they are always seeking for more. To do their duty is their only holiday, and they deem the quiet of inaction to be as disagreeable as the most tiresome business. If a man should say of them, in a word, that they were born neither to have peace themselves nor to allow peace to other men, he would simply speak the truth.

"In the face of such an enemy, Lacedaemonians, you persist in doing nothing. But let your procrastination end. Do not allow friends and kindred to fall into the hands of their worst enemies; or drive us in despair to seek the alliance of others; in taking such a course we should be doing nothing wrong either before the Gods who are the witnesses of our oaths, or before men whose eyes are upon us. For the true breakers of treaties are not those who, when forsaken, turn to others, but those who forsake allies whom they have sworn to defend. We will remain your friends if you choose to bestir yourselves; for we should be guilty of an impiety if we deserted you without cause; and we shall not easily find allies equally congenial to us. Take heed then; you have inherited from your fathers the leadership of Peloponnesus; see that her greatness suffers no diminution at your hands."

Thus spake the Corinthians. Now there happened to be staying at Lacedaemon an Athenian embassy which had come on other business, and when the envoys had heard what the Corinthians had said, they felt bound to go before the Lacedaemonian assembly, not with the view of answering the accusations brought against them by the cities, but they wanted to put before the Lacedaemonians the whole question, and make them understand that they should take time to deliberate and not be rash. They also desired to set forth the greatness of their city, reminding the elder men of what they knew, and informing the younger of what lay beyond their experience. They thought that their words would sway the Lacedaemonians in the direction of peace. So they came and said that, if they might be allowed, they too would like to address the people.[[2]]

The Athenians were invited to speak, and they reminded the Spartans of how Athens had done more than any other State to save Greece from the Persian invader, and that Sparta herself owed her liberty to the undismayed courage of Athens.

We maintain, [they said], that we rendered you a service at least as great as you rendered us. The cities from which you came to help us were still inhabited and you might hope to return to them; your concern was for yourselves and not for us; at any rate you remained at a distance while we had anything to lose. But we went forth from a city which was no more, and fought for one of which there was small hope; and yet we saved ourselves, and bore our part in saving you. If, in order to preserve our land, like other states, we had gone over to the Persians at first, or afterwards had not ventured to embark because our ruin was already complete, it would have been useless for you with your weak navy to fight at sea, but everything would have gone quietly just as the Persian desired.[[3]]
