Doctor Mader went on, "The Chief Officer arranged it." She smiled wryly. "She's glad to get rid of me. I hadn't had any hope that she could put it over, in view of the difficulty in getting me aboard Sisu; I think your grandmother must have some bargaining point that she did not mention. In any case I'm to go... with the understanding that I remain in strict purdah. I shan't mind; I'll use the time on my data."

Mention of purdah reminded Thorby that Margaret would see Mata. He started with stumbling embarrassment to explain what he had come to talk about. Doctor Mader listened gravely, her fingers busy with packing. "I know, Thorby. I probably heard the sad details sooner than you did."

"Margaret, did you ever heard of anything so silly?"

She hesitated. "Many things... much sillier."

"But there wasn't anything to it! And if that was what Mata wanted, why didn't Grandmother let her... instead of shipping her out among strangers. I... well, I wouldn't have minded. After I got used to it."

The fraki woman smiled. "That's the oddest gallant speech I ever heard, Thorby."

"Thorby said, "Could you get a message to her for me?"

"Thorby, if you want to send her your undying love or something, then don't. Your Grandmother did the best thing for her great granddaughter, did it quickly with kindness and wisdom. Did it in Mata's interests against the immediate interests of Sisu, since Mata was a valuable fighting man. But your Grandmother measured up to the high standards expected of a Chief Officer; she considered the long-range interests of everyone and found them weightier than the loss of one firecontrolman. I admire her at last -- between ourselves, I've always detested the old girl." She smiled suddenly. "And fifty years from now Mata will make the same sort of wise decisions; the sept of Sisu is sound."

"I'll be flogged if I understand it!"

"Because you are almost as much fraki as I am... and haven't had my training. Thorby, most things are right or wrong only in their backgrounds; few things are good or evil in themselves. But things that are right or wrong according to their culture, really are so. This exogamy rule the People live by, you probably think it's just a way to outsmart mutations -- in fact that's the way it is taught in the ship's school."

"Of course. That's why I can't see --"

"Just a second. So you can't see why your Grandmother should object. But it's essential that the People marry back and forth among ships, not just because of genes -- that's a side issue -- but because a ship is too small to be a stable culture. Ideas and attitudes have to be cross-germinated, too, or Sisu and the whole culture will die. So the custom is protected by strongest possible taboo. A 'minor' break in this taboo is like a 'minor' break in the ship, disastrous unless drastic steps are taken. Now... do you understand that?"

"Well... no, I don't think so."

"I doubt if your Grandmother understands it; she just knows what's right for her family and acts with forthrightness and courage. Do you still want to send a message?"

"Uh, well, could you tell Mata that I'm sorry I didn't get to say good-by?"

"Mmm, yes. I may wait a while."

"All right."

"Feeling better yourself?"

"Uh, I guess so... since you say it's best for Mata." Thorby suddenly burst out, "But, Margaret, I don't know what is the matter with me! I thought I was getting the hang of things. Now it's all gone to pieces. I feel like a fraki and I doubt if I'll ever learn to be a Trader."

Her face was suddenly sad. "You were free once. It's a hard habit to get over."

"Huh?"

"You've had violent dislocations, Thorby. Your foster father -- your first one, Baslim the Wise -- bought you as a slave and made you his son, as free as he was. Now your second foster father, with the best of intentions, adopted you as his son, and thereby made you a slave."

"Why, Margaret!" Thorby protested. "How can you say such a thing?"

"If you aren't a slave, what are you?"

"Why, I'm a Free Trader. At least that's what Father intended, if I can ever get over my fraki habits. But I'm not a slave. The People are free. All of us."

"All of you... but not each of you."

"What do you mean?"

"The People are free. It's their proudest boast. Any of them can tell you that freedom is what makes them People and not fraki. The People are free to roam the stars, never rooted to any soil. So free that each ship is a sovereign state, asking nothing of anyone, going anywhere, fighting against any odds, asking no quarter, not even cooperating except as it suits them. Oh, the People are free; this old Galaxy has never seen such freedom. A culture of less than a hundred thousand people spread through a quarter of a billion cubic light-years and utterly free to move anywhere at any time. There has never been a culture like it and there may never be again. Free as the sky... more free than the stars, for the stars go where they must. Ah, yes, the People are free." She paused. "But at what price was this freedom purchased?"

Thorby blinked.

"I'll tell you. Not with poverty. The People enjoy the highest average wealth in history. The profits of your trading are fantastic. Nor has it been with cost to health or sanity. I've never seen a community with less illness. Nor have you paid in happiness or self-respect. You're a smugly happy lot, and your pride is something sinful -- of course you do have a lot to be proud of. But what you have paid for your unparalleled freedom... is freedom itself. No, I'm not talking riddles. The People are free... at the cost of loss of individual freedom for each of you -- and I don't except the Chief Officer or Captain; they are the least free of any."

Her words sounded outrageous. "How can we be both free and not free?" he protested.

"Ask Mata. Thorby, you live in a steel prison; you are allowed out perhaps a few hours every few months. You live by rules more stringent than any prison. That those rules are intended to make you all happy -- and do -- is beside the point; they are orders you have to obey. You sleep where you are told, you eat when you are told and what you are offered -- it's unimportant that it is lavish and tasty; the point is you have no choice. You are told what to do ninety percent of the time. You are so bound by rules that much of what you say is not free speech but required ritual; you could go through a day and not utter a phrase not found in the Laws of Sisu. Right?"

"Yes, but --"

"Yes, with no 'buts.' Thorby, what sort of people have so little freedom? Slaves? Can you think of a better word?"

"But we can't be sold!"

"Slavery has often existed where slaves were never bought and sold, but simply inherited. As in Sisu. Thorby, being a slave means having someone as your master, with no hope of changing it. You slaves who call yourselves the 'People' can't even hope for manumission."

Thorby scowled. "You figure that's what's wrong with me?"

"I think your slave's collar is chafing you, in a fashion that does not trouble your shipmates -- because they were born with theirs and you were once free." She looked at her belongings. "I've got to get this stuff into El Nido. Will you help me?"

"I'd be glad to."

"Don't expect to see Mata."

"I wasn't," Thorby fibbed. "I want to help you. I hate to see you leave."

"Truthfully, I don't hate to leave... but I hate to say good-by to you." She hesitated. "I want to help you, too. Thorby, an anthropologist should never interfere. But I'm leaving and you aren't really part of the culture I was studying. Could you use a hint from an old woman?"

"Why, you aren't old!"

"That's two gallant speeches. I'm a grandmother, though the Chief Officer might be startled to hear me claim that status. Thorby, I thought you would become adjusted to this jail. Now I'm not sure. Freedom is a hard habit to break. Dear, if you decide that you can't stand it, wait until the ship calls at a planet that is democratic and free and human -- then hit dirt and run! But, Thorby, do this before Grandmother decides to marry you to someone, because if you wait that long -- you're lost!"
