the second is content to see the triumph of neither. Should we not choose the first, friend Giskard?"
"Yes, friend Daneel. So it would seem. And yet how far are you influenced by your feeling of the special worth of your onetime partner, Elijah Baley?"
Daneel said, "I value the memory of Partner Elijah and the people of Earth are his people."
"I see you do. I have been saying for many decades that you tend to think like a human being, friend Daneel, but I wonder if that is necessarily a compliment. Still, though you tend to think like a human being, you are not a human being and, in the end, you are bound to the Three Laws. You may not harm a human being, whether that human being is an Earthman or a Spacer."
"There are times, friend Giskard, when one must choose one human being over another. We have been given special orders to protect Lady Gladia. I would be forced, on occasion, to harm a human being in order to protect Lady Gladia and I think that, all things being equal, I would be willing to harm a Spacer just a little in order to protect an Earthperson."
"So you think. But in the actual event, you would have to be guided by specific circumstances. You will find you cannot generalize," said Giskard. "And so it is with me. In encouraging Earth and discouraging Aurora, I have made it impossible for Dr. Fastolfe to persuade the Auroran government to sponsor a policy of emigration and to set up two expanding powers in the Galaxy. I could not help but realize that that portion of his labors was brought to nothing. This was bound to fill him with gathering despair and perhaps it hastened his death. I have felt this in his mind and that has been painful. And yet, friend Daneel - "
Giskard paused and Daneel said, "Yes?"
"To have not done as I had done might have greatly lowered Earth's ability to expand, without greatly improving Aurora's moves in that direction. Dr. Fastolfe would then have been frustrated - in both ways - Earth and Aurora and would moreover have been ousted from his seat of power by Dr. Amadiro. His sense of frustration would have been greater. It was Dr. Fastolfe, during his lifetime, to whom I owed my greatest loyalty and I chose that course of action which frustrated him less, without measurably harming other individuals I dealt with. If Dr. Fastolfe was continually disturbed by his inability to persuade Aurorans - and Spacers generally - to expand to new worlds, he was at least delighted by the activity of the emigrating Earthpeople."
"Could you not have encouraged both the people of Earth and of Aurora, friend Giskard, and thus have satisfied Dr. Fastolfe in both respects?"
"That, of course, had occurred to me, friend Daneel. I considered the possibility and decided it would not do. I could encourage Earthpeople to emigrate by means of a trifling change that would do no harm. To have attempted the same for Aurorans would have required a great enough change to do much harm. The First Law prevented that."
"A pity."
"True. Think what might have been done if I could have radically altered the mind-set of Dr. Amadiro. Yet how could I have changed his fixed determination to oppose Dr. Fastolfe? It would have been much like trying to force his head to make a one hundred and eighty degree turn. So complete a turnabout of either the head itself or of its emotional content would kill with, I think, equal efficiency.
"The price of my power, friend Daneel," Giskard went on, "is the greatly increased dilemma into which I am constantly plunged. The First Law of Robotics, which forbids injury to human beings, deals, ordinarily, with the visible physical injuries that we can, all of us, easily see and concerning which we can easily make judgments. I, alone, however, am aware of human emotions and of casts of mind, so that I know of more subtle forms of injury without being able to understand them completely. I am forced on many occasions to act without true certainty and this puts a continuing stress on my circuits.
"And yet I feel I have done well. I have carried the Spacers past the crisis point. Aurora is aware of the gathering strength of the Settlers and will now be forced to avoid conflict. They must recognize it to be too late for retaliation and our promise to
