should have been able to think so creatively and to transmute his thoughts into such extraordinary accomplishments. Perhaps it was the truth; but it was a painful truth for Andrew to face, and there seemed no way of escaping it.
Magdescu was the last to speak.
It had been a very long evening, and Magdescu looked pale and tired as he stood up. But Andrew, who was seated next to him, observed him making a strenuous effort to pull himself together, raising his head high, squaring his shoulders, filling his lungs-his Andrew Martin Laboratories prosthetic lungs-with a deep draught of air.
"My friends, I won't waste your time repeating the things that everyone else has said here tonight. We all know what Andrew Martin has done for mankind. Many of us have experienced his work at first hand-for I know that sitting before me tonight as I speak are scores of you who have Andrew's prosthetic devices installed in your bodies. And I am of your number. So I want to say, simply, that it was my great privilege to work with Andrew Martin in the early days of prosthetology-for I myself played a small part in the development of those devices of his which are so essential to our lives today. And in particular I want to acknowledge that I would not be here tonight but for Andrew Martin. But for him and his magnificent work, I would have been dead fifteen or twenty years ago-and so would many of you.
"Therefore, my friends, let me propose a toast. lift your glasses with me now, and take a sip of this good wine, in honor of the remarkable individual who has brought such great changes to medical science, and who today attains the imposing and significant age of one hundred fifty years-I give you, my friends, Andrew Martin, the Sesquicentennial Robot!"
Andrew had never managed to cultivate a liking for wine or even any understanding of its merits, but as a result of his combustion-chamber upgrades at least he had the physiological capacity to consume it. Sometimes he actually did, when social contexts seemed to require him to. And so when Alvin Magdescu turned toward him, therefore, his eyes shining with emotion, his face flushed, his glass upraised, Andrew raised his own glass in response, and downed a long drink of the wine that it contained.
But in fact he felt little joy. Though the sinews of his face had long since been redesigned to display a range of emotions, he had sat through the entire evening looking solemnly passive, and even at this climactic moment he could manage nothing better than a perfunctory half-smile. Even that took effort. Magdescu had meant well, but his words had given Andrew pain. He did not want to be a Sesquicentennial Robot.
Chapter Eighteen
IT WAS PROSTHETOLOGY that finally took Andrew off the Earth. He had not felt any need in the past to take trips into space-or to travel very widely on Earth itself, for that matter-but Earth was no longer the prime center of human civilization, and most of what was new and eventful was taking place in the offworld settlements-notably on the Moon, which now had come to be a world more Earthlike than Earth in every respect but its gravitational pull. The underground cities that had begun as mere crude cavern-shelters in the Twenty-First Century now were opulent, brightly lit cities, densely populated and rapidly growing.
The citizens of the Moon, like humans everywhere, had need of prosthetic work. No one was content any more with the traditional three score and ten, and when organs broke down, it was standard procedure to replace them.
But the low lunar gravity, though in some ways it had its advantages for humans living under reduced gravitational stress, created a host of problems for the prosthetic surgeons. Devices designed to deliver a smooth and regular flow of blood or hormones or digestive fluid or some other fundamental substance of life in Earth's gravity would not function as reliably under a gravitational pull that was only one sixth as great. There were problems, too, of tensile strength, of durability, of unexpected and unwanted feedback complications.
The lunar prosthetologists had begged Andrew for years to visit the Moon and get a first-hand look at the problems of adaptation that they were forced to deal with. The U. S. Robots marketing division on the Moon repeatedly urged him to go.
On a couple of occasions, it was even suggested that, under the terms of the licensing agreement,
