something that might indeed be called love. His love, for them. In his earlier days Andrew would never have admitted such a thing, even to himself; but he was different now.
These thoughts led Andrew inevitably, around the time of Paul Charney's death, to a consideration of the entire concept of family ties-the love of parent for child, of child for parent-and how that was related to the inexorable passing of the generations. If you are human, Andrew told himself, you are part of a great chain, a chain that hangs suspended across vast spans of time and links you to all those who have come before you and those who follow after. And you understand that individual links of the chain may perish-indeed, must perish-but the chain itself is ever-renewing and will survive. People died, whole families might become extinct-but the human race, the species, went on and on through the centuries and the millennia and the eons, everyone connected through the heritage of blood to those who had gone before.
It was a difficult thing for Andrew to understand, that sense of connection, of infinite linkage with intimately related predecessors. He had no predecessors, not really, and he would have no successors, either. He was unique-individual-something that had been brought forth at a certain moment in time out of nothing at all.
Andrew found himself wondering what it might be like to have had a parent himself-but all he could come up with was a vague image of assembly-robots weaving his body together in a factory. Or what it was like to have a child-but the best he could manage was to envision a table or desk, something that he had made with his own hands.
But human parents were not assembly-mechs, and human children were nothing like tables and desks. He had it all wrong.
It was a mystery to him. And very likely always would be. He was not human; why then should he expect human family linkages to be comprehensible to him?
Then Andrew thought of Little Miss, of George, of Paul, even of fierce old Sir, and what they had meant to him. And he realized that he was part of a family chain after all, though he had had no parents and was incapable of siring children. The Martins had taken him in and had made him one of them. He was a Martin, indeed. An adopted Martin, yes; but that was the best he could have hoped for. And there were plenty of humans who had not had the comfort of belonging to such a loving family. He had done very well, all things considered. Though only a robot, he had known the continuity and stability of family life; he had known warmth; he had known love.
All those whom Andrew had-loved-were gone, though. That was saddening and liberating both. The chain was broken, for him. It could never be restored. But at least he could do as he pleased, now, without fear of troubling those who had been so close to him. Now, with the death of the great-grandson of Sir, Andrew felt free to proceed with his plan for upgrading his android body. That was some sort of partial consolation for his loss.
Nevertheless he was alone in the world, or so it seemed to him-not simply because he was a positronic brain in a unique android body, but because he had no affiliations of any sort. And it was a world that had every reason to be hostile to his aspirations. All the more reason, Andrew thought, to continue along the path he had long ago chosen-the path that he hoped would ultimately make him invulnerable to the world into which he had been thrust so impersonally, without his leave, so many years before.
In fact Andrew was not quite as alone as he thought. Men and women might die, but corporations lived on just as robots did, and the law firm of Feingold and Charney still functioned even though no Feingolds and no Charneys remained. The firm had its directions and it followed them impeccably and soullessly. By way of the trust that held his investments and through the income that Andrew drew from the firm as Paul Charney's heir, Andrew continued to be wealthy. That enabled him to pay a large annual retainer to Feingold and Charney to keep them involved in the legal aspects of his research-in particular, the new combustion chamber.
It was time now for Andrew to pay another call on the headquarters of
