"But some fundamentalists do come across evidence that they'd like to ignore. Iron strikes flint, and the spark falls on inflammable material. The fire is off to the races, as it were. He reads more of the evidence, perhaps loathes and curses himself for his 'sinful' curiosity. But he learns more and more. Finally, his reason convinces him that he's been wrong. And he becomes a liberal Christian or an atheist or agnostic.

"Something in his genetic defenses made a hole or the hole already existed waiting for water to pour through it.

"In any event, he was able to use his reason only because his genetic makeup permitted him."

"I thought you said that Homo sapiens was a semirobot," Burton said. "You're describing one hundred percent robots."

"No. Robots don't have reason. They can use logic, if they've been programmed to do it. But, if presented with new evidence that says that their program is wrong, they can't reject the already installed program. Humans can. Sometimes. Nor do robots have to rationalize their reasons for the way they behave. They just do, but humans have to explain why they're doing such and such. They construct a system of logic to excuse their behavior. The system may be founded on wrong premises, but it's usually logical within its own frame of reference. Not always, though.

"What the Ethicals claim, and they can prove it, is that even the most genetically rigid, the most severely conditioned person has the ability to free himself—partially, anyway—from these constraints, these molds. That a few can do this but most don't ... the Ethicals say that this is a demonstration of free will. The restrained, the strait-jacketed, don't want to change. They are happy in their misery."

"They can prove this?"

"Yes. I'll admit I'm not educated enough to validate their findings. I don't understand the higher mathematics or the extremely involved biology. I accept their proofs, however."

"There is no such thing as absolute or final certainty, is there?" Burton said. "Unless you can see clearly, as through a crystal, exactly what evidence they present, you won't ever really know if they have the truth, will you?"

"Put that way, no. Some things have to be accepted on faith."

Burton laughed uproariously.

The American, red-faced, said, "Unless you're competent to do the research yourself, how do you know that what you read in a chemistry or astronomy or biology book is true? How do you know that anything is true unless you duplicate the research? Even then, you may be in error or clinging to the opposite viewpoint because ..."

"Because you're genetically inclined to it?" Burton said scornfully. "Because you're predetermined to believe in one thing and not in another?"

"An attitude like yours makes a man believe in almost nothing."

"Right," Burton drawled.

"You certainly voiced enough opinions based on the observations of others while you were on Earth. Often very wrong opinions."

"That was on Earth."

They were silent for a while. The women were talking about their mothers. Frigate could tell, however, that Sophie was listening to them at the same time. She winked at him and made a gesture that he could not interpret.

Frigate picked up the subject again as if it were a football and he was going to make a ninety-yard run. Doggedly, he said, "About 1978, I think it was, I read in a psychology book that one out of ten men seemed to be a born leader. It was implied that this trait was genetically determined. The Ethical study has validated that and moreover pinpointed the genetic complex responsible.

"Also, it said that ten percent of Homo sapiens had always inclined to a certain degree towards homosexuality. The ten percent had certain inclinations, that is. Not all of the ten percent were practicing homosexuals, but the tendency was there. This had been the rule since the Ethicals started making duplicate records of humanity. And it was assumed that this had been so since Homo sapiens originated.

"The tendency is genetically determined. What interested me about this is that in 1983, a few years before that, too, the militant homosexuals claimed that they had made a free and conscious choice to be homosexuals. In other words, they weren't born homosexuals, they had deliberately chosen to be such because they preferred that sexual way of life.

"They talked as if, when you reached the age of reason, you made up your mind about your path of action. What they ignored or failed to consider, was that, if this were true, then heterosexuals also made their free and conscious decision to be heterosexual. But this just wasn't so. A heterosexual was so because he was born so."

"What about ... ?" Burton said.

"You were going to say, 'What about those who have homosexual tendencies but behave heterosexually? Or those who are bisexuals? Or those who marry women but have homosexual affairs on the side?' There are varying degrees of homosexuality ... and heterosexuality ... of course. And in any society where it was dangerous to be openly homosexual, the homosexual had to hide his or her tendency. In any event, homosexuality or heterosexuality is not a matter of choice. It's inborn.

"That makes no difference. Being homosexual or not is not a matter of morality. It's not a person's decision. It's what you do with your homosexuality or heterosexuality that matters, that is moral. Rape, sadism, violence are evil whether or not you're homosexual."

Sophie spoke up. "I can't help overhearing you two, you're so loud. What's all this about free will and determinism and genes and choice? I was very interested in those subjects when I went to college. Really interested. I got passionate about such things, I used to enjoy getting angry at those who didn't agree with me, the stupid jerks! But when I graduated, no, some time before that, I saw that ... well ... thinking you can solve anything by discussing philosophy or those other matters was foolish. There's no end to it, no possible irrefutable conclusions. Fun, maybe, but profitless. Sophomoric. It really is. So I quit talking about it. If somebody wanted to discuss such things, I steered them to some other subject or just walked away, though I wasn't rude about it."

"Sure, that's right!" Frigate said. "You were right! But the point is that the Ethicals have put these subjects beyond the range of discussion or opinion. They've proved these points. We're no longer in the dark!"

"Maybe. I have to agree with Dick about that. Maybe. But that doesn't matter. What was it Buddha said? 'Work out your own salvation with diligence.' Whoever Mr. or Mrs. Diligence is. I've been looking for Mr. Diligence for a long time. I even borrowed Diogenes' lantern to help me. Which, by the way, the old Greek didn't need. He was honest, why should he go out looking for another honest person?

"Anyway, as Dick said, we all act as if we had free will. So who cares if there is such a thing? All I know is that only I, I alone, am responsible for my moral behavior. Heredity, environment, excuses. Excuses, alibis: scorned. Race, nationality, tribe, parents, religion, society: excuses. I decide what I am. And that's that!"

"Was that why you burned your souffle yesterday?" Frigate said. "You didn't just forget about watching it. You decided to cremate it?"

Frigate and Lefkowitz burst out laughing. Burton said, "You cook?"

"Why, yes," Sophie said. "I like to cook. When it's not required of me, that is. I was making our dinner last night, and I forgot to watch the souffle. I was reading a book, and ..."

They started talking about food and that led to other subjects and finally to dinner. Eating together was a custom more ancient than conversation.
