"They had better go back to it."
"But if Nature herself seemed to change her mind about you?"
"Ah, you mean persons of weak will. They are a great curse to themselves and to everybody else."
"I'm not so sure of that," said Colville. "I've seen cases in which a strong will looked very much more like the devil."
"Yes, a perverted will. But there can be no good without a strong will. A weak will means inconstancy. It means, even in good, good attempted and relinquished, which is always a terrible thing, because it is sure to betray some one who relied upon its accomplishment."
"And in evil? Perhaps the evil, attempted and relinquished, turns into good."
"Oh, never!" replied the minister fervently. "There is something very mysterious in what we call evil. Apparently it has infinitely greater force and persistence than good. I don't know why it should be so. But so it appears."
"You'll have the reason of that along with the rest of the secret when your revelation comes," said Colville, with a smile. He lifted his eyes from the river, and looked up over the clustering roofs beyond it to the hills beyond them, flecked to the crest of their purple slopes with the white of villas and villages. As if something in the beauty of the wonderful prospect had suggested the vision of its opposite, he said, dreamily, "I don't think I shall go to Rome to-morrow, after all. I will go to Des Vaches! Where did you say you were walking, Mr. Waters? Oh yes! You told me. I will cross the bridge with you. But I couldn't stand anything quite so vigorous as the associations of the siege this afternoon. I'm going to the Boboli Gardens, to debauch myself with a final sense of nerveless despotism, as it expressed itself in marble allegory and formal alleys. The fact is that if I stay with you any longer I shall tell you something that I'm too old to tell and you're too old to hear." The old man smiled, but offered no urgence or comment, and at the thither end of the bridge Colville said hastily, "Good-bye. If you ever come to Des Vaches, look me up."
"Good-bye," said the minister. "Perhaps we shall meet in Florence again."
"No, no. Whatever happens, that won't."
