"Many people do, but they aren't," Arif told her. " `Communication' can be used to identify a lot of activities, from the way animals relate to one another, to a deep philosophical discussion between humans on the Meaning of Life, to the way electronic devices transfer information from one location to another. They're all communication, of a sort, at least. But human communication — language — is the means by which two sentient beings exchange value-laden symbols. Feelings and ideas have no physical substance, Ms. LaFollet. We can't just hand them back and forth the way we would an apple or an orange or a brick, so we devise symbols which carry their weight, and we call those symbols words. A child, immersed in a language-saturated environment and motivated by the need to express its own desires and needs to those upon whom it depends, learns to associate certain patterns of sound with certain meanings, but that's only the begi

"In addition to acquiring associations between sound and symbol, learning a language also requires one to deduce — or, in the case of children, absorb — the rules for the way the sounds are put together. Each sound can be thought of as an individual building block or sound bit. What we call a `phoneme' is the smallest bit of sound that may change or alter meaning, which usually means a vowel or a consonant, and phonemes vary from language to language. Let's take Spanish and English as an illustration, since San Martin's been in the news so much of late. In Spanish, the `sp' phoneme never begins a word; in Standard English, however, that's quite a common begi

"On its own, a phoneme usually has no meaning, but groups of them combine in strings or patterns which do have meaning. We call the smallest string of sound which does have meaning a `morpheme,' which is a sound — it may be a word on its own, or only a part of a word — which can't be broken down any further. Take `biker,' for instance. `Bike' is a morpheme. It can't be broken down any further and retain its meaning. But by adding an additional phoneme—`er' to it — we tell our listener that we're talking about someone who rides a bike. We can go further and add yet another phoneme, `s' to it, in which case we create the plural form and tell our listener we're speaking of more than one person, all of whom ride bikes. And to complicate things still further, `bike' can be either a verb or a noun, and our listener has to determine which we intend for it to be from the way in which we position and use the word. `He bikes' means the person we're speaking of rides a bike. `His bikes' means the person owns more than one bike. As you can see, the very tiny difference — the use of `he' instead of `his'—makes an enormous difference in the concept being communicated, and that doesn't even begin to get into verb tenses, temporal and spatial references, stress and emphasis patterns, or any of the other enormous number of shared conventions which go into a true language."

She paused, and Miranda nodded slowly, her expression thoughtful.

"What you might think of as a `full-blown' language isn't the only way to communicate, of course. As I said, it's well established that treecats use at least some vocal signals, but signals don't necessarily equate to language. For example, if I scream as a hexapuma leaps on me, that's a signal. It's not language, however. Most probably, anyone who hears me will know I'm very unhappy over something, but I haven't communicated anything more than that, nor can I with a signal that simple and crude.

"The main problem here, however, is that 'cats don't use phonemes or morphemes. So far as we can tell, they don't use a spoken language at all. From Her Grace's explanation of her link with Nimitz, it's clear the people who theorized that the 'cats were telepaths were right all along, and the tests Doctor Brewster and his people have conducted over the last several months confirm it, conclusively, in my opinion. But we aren't telepaths. We don't have the least idea what the ability to communicate directly, mind-to-mind, without the intrusion of a secondary interface like language, means to the way they think and receive and process information. In my opinion, it's not only possible but probable that they've never developed the sort of `bit-based' format we humans have had no option but to use, and that could be a very serious problem."

"Because they won't have any inbuilt referent for what we're trying to teach them?" Miranda asked, her expression still intent, and Arif nodded firmly.

"Exactly. All humans rely on some physical form of language to communicate, and so, with the exception of the 'cats, does every other sentient species we've encountered. That means anyone we've ever tried to teach a language, or learn a language from, at least shared certain utterly basic concepts and mental tools. But the 'cats almost certainly lack those mental tools, and that puts us in the position of someone who has to go back and invent the wheel all over again. Actually, inventing the wheel would be easy compared to what we have to do here, because at least we could physically demonstrate our invention for someone who'd never thought of it before."





"I understand what you're saying, Doctor," Honor said, "but I think you may be overly concerned. Anyone who's been adopted knows the 'cats understand us when we talk to them."

"Forgive me, Your Grace, but we don't know that," Arif replied. "I'll certainly grant that the evidence strongly suggests you're correct, but we haven't got any proof you are because no one has ever successfully established true two-way communication."

"Yes, someone has," Honor replied, her tone nonconfrontational but firm. Very firm. "Nimitz and I have. Not through the sort of interface you're talking about, of course, but I know when he understands me. Confusion is a very distinctive `tasting' emotion, I assure you. There are times when I have to pick words carefully, especially when I start dealing with concepts 'cats simply haven't had to develop, like heavy-metal toxicity," she said, flashing a smile at Miranda. "But he usually understands me at least as well as most human adolescents I've tried to explain things to."

"I don't doubt he does, Your Grace. And I didn't say he didn't; I only said we can't prove it... yet. And while I hope your analysis is correct, I also have to point out that you do have a special link to Nimitz. One which no one else, to the best of our knowledge, has ever shared. It's possible that at least a part of what you believe you're communicating to him with your words is actually reaching him over that link. It's even possible that a part of what all 'cats `hear' from all humans is enhanced by an ability on their part to perceive the thoughts behind our words. For purposes of applied cognitive effort, humans tend to think in language, to organize the syntax of our thought processes in the fashion in which we're accustomed to receiving information, so perhaps what's actually happening is that we're putting words together to communicate with them, but what they're actually `hearing' is the mental organization behind the words."

"I suppose that's possible," Honor acknowledged with a frown. It was odd, but the possibility Arif was suggesting had never occurred to her, and it should have. "I don't think it's what's happening, but I can't dismiss the possibility out of hand."

"As I say, I hope it isn't what's happening," Arif said, "because it's clear Nimitz's injuries have completely silenced his ability to send thoughts to Samantha. Or, put another way, she can't `hear' anything from him, which means she wouldn't be able to `hear' the thoughts behind the signs we might teach him to make.
