"Well, consider abortion. It was advancing science that propelled that into being a mainstream issue; the technology to reliably terminate a fetus without killing or maiming the mother is a scientific innovation. We can do this now, but should we do it?"

"But," he said, "suppose the Dracons really are dragons — you know, suppose they’re reptiles. I know they probably aren’t; I know the name refers to the constellation they happen to be in from our point of view. But bear with me. If you had a race of intelligent reptiles, then abortion isn’t a technological issue. Smashing the egg in the nest doesn’t physically harm the mother in any way."

"Yeah, okay, granted," she said. The pebble Don had kicked was now in her path, and she sent it skittering ahead. "But that’s not the counterpart of abortion; the counterpart of abortion would be destroying the fertilized egg before it’s laid while it’s still inside the mother."

"But some fish reproduce by having the female eject unfertilized eggs into the water, and the male eject semen into the water, so that fertilization takes place outside the female’s body."

"Okay, all right," said Sarah. "Beings like that wouldn’t have the abortion issue in precisely the same way, but, then again, like I said on As It Happens, aquatic beings probably don’t have radio or other technology."

"But, still, why is abortion a moral issue? I mean, it is for people here because we believe at some point a soul enters the body; we just can’t all agree on what that point is. But the alien message made no mention of souls."

’"Souls’ is just a shorthand for discussing the question of when life begins, and that will be a universal debate — at least among those races who practice SETI."

"Why?"

"Because SETI is an activity that says life, as opposed to non-life, is important, that finding life is meaningful. If you didn’t care about the distinction between life and nonlife, all you’d do would be astronomy, not SETI. And where to draw that distinction will always be of interest to people who value life. I mean, most people would agree it’s wrong to kill a dog for no reason, because a dog is clearly alive — but is an embryo alive? That’s debatable; every race will have to define when life begins."

"Well, it either begins at conception or at birth, no?"

Sarah shook her head. "No. Even here on Earth, there are cultures that don’t name kids until they’ve lived forty days, and I’ve even heard it argued that babies aren’t people until they turn three or so — until they begin to form long-term, permanent memories. And even then, there’s still room for moral debate. We know the Dracons reproduce sexually, shuffling their genes while doing so; that was clear from their message. And I rather suspect, by the way, that that sort of reproduction will be common throughout the universe: it provides a huge kick to evolution, getting a new genetic hand dealt with every generation instead of having to wait around for a cosmic ray to induce a random mutation in a being that otherwise just reproduces exact copies of itself. Remember, life first appeared on this planet four billion years ago, and it spent the first three and a half billion of those years basically the same.

But when sex was invented half a billion years ago, in the Cambrian explosion — boom! — suddenly evolution was proceeding by leaps and bounds. And any race that reproduces sexually might very well still argue about the ethics of destroying a unique combination of genetic material even if they’ve always held that such a thing wasn’t alive until the moment of birth."

Don frowned. "That’s like saying it’s a moral quandary to worry about destroying snowflakes. Just because something is unique doesn’t make it valuable — especially when everything in that class of entities is unique."

A chipmunk scampered across the road in front of them. "Besides," continued Don, "speaking of evolution, doesn’t the abortion issue ultimately take care of itself, given enough time? I mean, natural selection obviously would favor those people who actually put into practice being pro-life over those who actually choose to personally have abortions, because every fetus you abort is one less set of your genes around. You wait enough generations, and being pro-choice should be bred out of the population."
