Daneel said, "You yourself, friend Giskard, said that it was an autocatalytic effect, a matter of contagion. A single spark of flame may end by burning down a forest."
Giskard paused and seemed deep in thought. Then he said, "It is not reason that is contagious but emotion. Madam Gladia chose arguments she felt would move her audience's feelings. She did not attempt to reason with them. It may be, then, that the larger the crowd, the more easily they are swayed by emotion rather than by reason.
"Since emotions are few and reasons are many, the behavior of a crowd can be more easily predicted than the behavior of one person can. And that, in turn, means that if laws are to be developed that enable the current of history to be predicted, then one must deal with large populations, the larger the better. That might itself be the First Law of Psychohistory, the key to the study of Humanics. Yet - "
"Yes?"
"It strikes me that it has taken me so long to understand this only because I am not a human being. A human being would, perhaps, instinctively understand his own mind well enough to know how to handle others like himself. Madam Gladia, with no experience at all in addressing huge crowds, carried off the matter, expertly. How much better off we would be if we had someone like Elijah Baley with us.
"Friend Daneel, are you not thinking of him?"
Daneel said, "Can you see his image in my mind? That is surprising, friend Giskard."
"I do not see him, friend Daneel. I cannot receive your thoughts. But I can sense emotions and mood - and your mind has a texture which, by past experience, I know to be associated with Elijah Baley."
"Madam Gladia made mention of the fact that I was the last to see Partner Elijah alive, so I listen again, in memory, to that moment. I think again of what he said."
"Why, friend Daneel?"
"I search for the meaning. I feel it was important."
"How could what he said have meaning beyond the import of the words? Had there been hidden meaning, Elijah Baley would have expressed it."
"Perhaps," said Daneel slowly, "Partner Elijah did not himself understand the significance of what he was saying."
10. AFTER THE SPEECH
42
Memory!
It lay in Daneel's mind like a closed book of infinite detail, always available for his use. Some passages were called upon frequently for their information, but only a very few were called upon merely because Daneel wished to feel their texture. Those very few were, for the most part, those that contained Elijah Baley.
Many decades ago, Daneel had come to Baleyworld while Elijah Baley was still alive. Madam Gladia had come with him, but after they entered into orbit about Baleyworld, Bentley Baley soared upward in his small ship to meet them and was brought aboard. By then, he was a rather gnarled man of middle age.
He looked at Gladia with faintly hostile eyes and said, "You cannot see him, madam."
And Gladia, who had been weeping, said, "Why not?"
"He does not wish it, madam, and I must respect his wishes."
"I cannot believe that, Mr. Baley."
"I have a handwritten note and I have a voice recording, madam. I do not know if you can recognize his handwriting or his voice, but you have my word of honor these are his and that no untoward influence was used upon him to produce - "
She went into her own cabin to read and listen alone. Then she emerged - with an air of defeat about her - but she managed to say firmly, "Daneel, you are to go down alone to see him. It is his wish. But you are to report to me everything that is done and said."
"Yes, madam," Daneel said.
Daneel went down, in Bentley's ship and Bentley said to him, "Robots are not allowed on this world, Daneel, but an exception is being made in your case because it is my father's wish and because he is highly revered here. I have no personal animus against you, you understand, but your presence here must be an entirely limited one. You will be taken directly to my father. When he is done with you, you will be taken back into orbit at once. Do you understand?"
"I understand, sir. How is your father?"
"He is dying," Bentley said with perhaps conscious brutality.
"I understand that, too," said Daneel, his voice quivering noticeably, not out of ordinary emotion but because the consciousness of the death of a human being, however unavoidable, disordered his positronic brain paths. "I mean, how much longer before he must die?"
"He should have died some time ago. He is tied to life because he refuses to go, until he sees you."
They landed. It was a large world, but the inhabited portion - if this were all - was small and shabby. It was a cloudy day and it had rained recently. The wide, straight streets were empty, as though what population existed there was in no mood to assemble in order to stare at a robot.
The ground-car took them through the emptiness and brought them to a house somewhat larger and more impressive than most. Together they entered. At an inner door, Bentley halted.
"My father is in there," he said sadly. "You are to go in alone. He will not have me there with you. Go in. You might not recognize him."
Daneel went into the gloom of the room. His eyes adjusted rapidly and he was aware of a body covered by a sheet inside a transparent cocoon that was made visible only by its faint glitter. The light within the room brightened a bit and Daneel could then see the face clearly.
Bentley had been right. Daneel saw nothing of his old partner in it. It was gaunt and bony. The eyes were closed and it seemed to Daneel that what he saw was a dead body. He had never seen a dead human being and when this thought struck him, he staggered and it seemed to him that his legs would not hold him up.
