A Case of Conscience

"And that, I beg you to observe, is completely irrational. It is based upon a set of axioms, a set of propositions which were 'given' from the beginning — though your Lithian sees no need to postulate any Giver. The Lithian, for instance Chtexa, believes in the sanctity of the individual. Why? Not by reason, surely, for there is no way to reason to that proposition. It is an axiom. Or: Chtexa believes in the right of juridical defense, in the equality of all before the code. Why? It's possible to behave rationally from the proposition, but it's impossible to reason one's way to it. It's given. If you assume that the responsibility to the code varies with the individual's age, or with what family he happens to belong to, logical behavior can follow from one of these assumptions, but there again One can't arrive at the principle by reason alone.

"One begins with belief: 'I think that all people ought to be equal before the law.' That is a statement of faith, nothing more. Yet Lithian civilization is so set up as to suggest that one can arrive at such basic axioms of Christianity, and of Western civilization on Earth as a whole, by reason alone — in the plain face of the fact that one cannot. One rationalist's axiom is another one's madness."

"Those are axioms," Cleaver growled. "You don't arrive at them by faith, either. You don't arrive at them at all. They're self-evident, that's the definition of an axiom."

"It was until the physicists kicked that definition to pieces," Ruiz-Sanchez said, with a certain grim relish. "There's the axiom that only one parallel can be drawn to a given line. It may be self-evident, but it's also untrue, isn't it? And it's self-evident that matter is solid. Go on, Paul, you're a physicist yourself. Kick a stone for me, and say, "Thus I refute Bishop Berkeley.'"

"It's peculiar," Michelis said hi a low voice, "that Lithian culture should be so axiom-ridden, without the Lithians being aware of it. I hadn't formulated it in quite these terms before, Paul, but I've been disturbed myself at the bottomless assumptions that lie behind Lithian reasoning — all utterly unprobed, although in other respects the Lithians are very subtle. Look at what they've done in solid-state chemistry, for instance. It's a structure of the purest kind of reason, and yet when you get down to its fundamental assumptions you discover the axiom: 'Matter is real.' How can they know that? How did logic lead them to it? It's a very shaky notion, in my opinion. If I say that the atom is just a-hole-inside-a-hole-through-a-hole, how can they controvert me?"

"But their system works," Cleaver said.

"So does our solid-state theory — but we work from opposite axioms," Michelis said. "Whether it works or not isn't the issue. The question is, what is it that's working? I don't myself see how this immense structure of reason which the Lithians have evolved can stand for an instant. It doesn't seem to rest on anything. 'Matter is real' is a crazy proposition, when you come right down to it; all the evidence points in exactly the opposite direction."

"I'm going to tell you," Ruiz-Sanchez said. "You won't believe me, but I'm going to tell you anyhow, because I have to. It stands because ifs being propped up. That's the simple answer and the whole answer. But first I want to add one more fact about the Lithians:

"They have complete physical recapitulation outside the body."

"What does that mean?" Agronski said.

"You know how a human child grows inside its mother's body. It is a one-celled animal to begin with, and then a simple metazoan resembling the fresh-water hydra or a simple jellyfish. Then, very rapidly, it goes through many other animal forms, including the fish, the amphibian, the reptile, the lower mammal, and finally becomes enough like a man to be born. I don't know how this was taught to you as a geologist, but biologists call the process recapitulation.

"The term assumes that the embryo is passing through the various stages of evolution which brought life from the single-celled organism to man, but on a contracted time scale. There is a point, for instance, in the development of the fetus when it has gills, though it never uses them. It has a tail almost to the very end of its time in the womb, and rarely it still has it when it is born; and the tail-wagging muscle, the pubococcygeus, persists in the adult — in women it becomes transformed into the contractile ring around the vestibule. The circulatory system of the fetus in the last month is still reptilian, and if it fails to be completely transformed before birth, the infant emerges as a 'blue baby" with patent ductus arteriosus, the tetralogy of Fallot, or a similar heart defect which allows venous blood to mix with arterial — which is the rule with terrestrial reptiles. And so on."

"I see," Agronski said. "It's a familiar idea; I just didn't recognize the term. I had no idea that the correspondence was that close either, come to think of it."
