"Your life is going to be short," said Anton. "And at the end, there will be pain, physical and emotional. You will grow too large for this world, too large for your heart. But you have always been too large of mind for an ordinary life, da? You have always been apart. A stranger. Human by name, but not truly a member of the species, excluded from all clubs."

Till now, Anton's words had been mere irritants, floating past him like falling leaves. Now they struck him hard, with a sudden rush of grief and regret that left him almost gasping. He could not help the hesitation, the change of stride that showed the others that these words had suddenly begun to affect him. What line had Anton crossed? Yet he had crossed it.

"You are lonely," said Anton. "And humans are not designed to be alone. It's in our genes. We're social beings. Even the most introverted person alive is constantly hungry for human association. You are no exception. Bean."

There were tears in his eyes, but Bean refused to acknowledge them. He hated emotions. They took control of him, weakened him.

"Let me tell you what I know," said Anton. "Not as a scientist- that road may not be utterly closed to me, but it's mostly washed out, and full of ruts, and I don't use it. But my life as a man, that door is still open."

"I'm listening," said Bean.

"I have always been as lonely as you," he said. "Never as intelligent, but not a fool, either. I followed my mind into my work, and let it be my life. I was content with that, partly because I was so successful that my work brought great satisfaction, and partly because I was of a disposition not to look upon women with desire." He smiled wanly. "In that era, of my youth, the governments of most countries were actively encouraging those of us whose mating instinct had been short-circuited to indulge those desires and take no mate, have no children. Part of the effort to funnel all of human endeavor into the great struggle with the alien enemy. So it was almost patriotic of me to indulge myself in fleeting affairs that meant nothing, that led nowhere. Where could they lead?"

This is more than I want to know about you, thought Bean. It has nothing to do with me.

"I tell you this," said Anton, "so you understand that I know something of loneliness, too. Because all of a sudden my work was taken away from me. From my mind, not just from my daily activities. I could not even think about it. And I quickly discovered that my friendships were not... transcendent. They were all tied to my work, and when my work went away, so did these friends. They were not unkind, they still inquired after me, they made overtures, but there was nothing to say, our minds and hearts did not really touch at any point. I discovered that I did not know anybody, and nobody knew me.

Again, that stab of anguish in Bean's heart. This time, though, he was not unprepared, and he breathed a little more deeply and took it in stride.

"I was angry, of course, as who would not be?" said Anton. "And do you know what I wanted?"

Bean did not want to say what he immediately thought of: death.

"Not suicide, never that. My life wish is too strong, and I was not depressed. I was furious. Well, no, I was depressed, but I knew that killing myself would only help my enemies-the government-accomplish their real purpose without having had to dirty their hands. No, I did not wish to die. What I wanted, with all my heart, was... to begin to live."

"Why do I feel a song coming on?" said Bean. The sarcastic words slipped out of him unbidden.

To his surprise, Anton laughed. "Yes, yes, it's such a cliché that it should be followed by a love song, shouldn't it? A sentimental tune that tells of how I was not alive until I met my beloved, and now the moon is new, the sea is blue, the month is June, our love is true."

Petra burst out laughing. "You missed your calling. The Russian Cole Porter"

"But my point was serious," said Anton. "When a man's life is bent so that his desire is not toward women, it does not change his longing for meaning in his life. A man searches for something that will outlast his life. For immortality of a kind. For a way to change the world, to have his life matter But it is all in vain. I was swept away until I existed only in footnotes in other men's articles. It all came down to this, as it always does. You can change the world-as you have, Bean, Julian Delphiki-you and Petra Arkanian, both of you, all those children who fought, and the ones who did not fight, all of you-you changed the world. You saved the world. All of humanity is your progeny. And yet... it is empty, isn't it? They didn't take it away from you the way they took my work from me. But time has taken it away. It's in the past, and yet you are still alive, so what is your life for?"

They were at the stone steps leading down into the water Bean wanted simply to keep going, to walk into the Mediterranean, down and down, until he found old Poseidon at the bottom of the sea, and deeper, to the throne of Hades. What is my life for?

"You found purpose in Thailand," said Anton. "And then saving Petra, that was a purpose. But what did you save her for? You have gone to the lair of the dragon and carried off the dragon's daughter- for that is what the myth always means, when it doesn't mean the dragon's wife-and now you have her, and... you refuse to see what you must do, not to her, but with her"

Bean turned to Petra with weary resignation. "Petra, how many letters did it take to make clear to Anton precisely what you wanted him to say to me?"

"Don't leap to conclusions, foolish boy," said Anton. "She only wanted to find out if there was any way to correct your genetic problem. She did not speak to me of your personal dilemma. Some of it I learned from my old friend Hyrum Graff. Some of it I knew from Sister Carlotta. And some of it I saw simply by looking at the two of you together. You both give off enough pheromones to fertilize the eggs of passing birds."

"I really don't tell our business to others," said Petra.

"Listen to me, both of you. Here is the meaning of life: for a man to find a woman, for a woman to find a man, the creature most unlike you, and then to make babies with her, with him, or to find them some other way, but then to raise them up, and watch them do the same thing, generation after generation, so that when you die you know you are permanently a part of the great web of life. That you are not a loose thread, snipped off."

"That's not the only meaning of life," said Petra. sounding a little annoyed. Well, thought Bean, you brought us here, so take your medicine, too.

"Yes it is," said Anton. "Do you think I haven't had time to think about this? I am the same man, with the same mind, I am the man who found Anton's Key, I have found many other keys as well, but they took away my work, and I had to find another. Well, here it is. I give it to you, the result of all my... study. Shallow as it had to be, it is still the truest thing I ever found. Even men who do not desire women, even women who do not desire men, this does not exempt them from the deepest desire of all, the desire to be an inextricable part of the human race."

"We're all part of it no matter what we do," said Bean. "Even those of us who aren't actually human."

"It's hardwired into all of us. Not just sexual desire-that can be twisted any which way, and it often is. And not just a desire to have children, because many people never get that, and yet they can still he woven into the fabric. No, it's a deep hunger to find a person from that strange, terrifyingly other sex and make a life together Even old people beyond mating, even people who know they can't have children, there's still a hunger for this. For actual marriage, two unlike creatures becoming, as best they can, one."

"I know a few exceptions," said Petra wryly. "I've known a few people of the 'never-again' persuasion."
