When I began this blog, I assumed the big step in developing language was the creation of the first word. I took it for granted that this was accomplished by yoking a sound and a meaning together to give us something like chair. I no longer believe either of those things.
Today I believe that the big step towards language came when our ancestors were willing to share their knowledge, and that language began when we started pointing things out to one another.
The change in my thinking resulted from a doodle I created early in the blog’s history: the speech triangle. Its corners mark a speaker and a listener who focus joint attention on the third corner, a topic. It might seem that we could eliminate the topic and just have that as something shared by speaker and listener, but the role of joint attention forces listener and speaker to focus on the topic rather than each other. If you try to eliminate the topic and redirect attention to the speech itself, you get pointless remarks—e.g., this sentence is six words long—or paradoxes such as: This sentence is false. The way out of this jumble is to realize that language works by directing attention away from the fact of communication to some other topic out there in the universe or in imagination. The topic is a distinct part of the speech triangle.
Embrace of the speech triangle puts an end to a search for any relevance in communication and information theory. Claude Shannon’s information theory presents a pair, speaker and receiver, and proposes that the function of communications is for the speaker to control a receiver at a distance. There is no role for either meaning or topic in such a definition. The theory is enough to explain computer networks, heredity, and the hormonal, immune, and nervous systems, but it is not rich enough to tell us anything about language. Efforts to calculate the information content of a sentence mix oranges and apples.
The speech triangle also implies that generative grammarians are on a wrong track. Traditional approaches to language imposes no function on verbal interactions; hence, grammar is not asked to contribute to any task. The speech triangle, however, locks in a function. Speaker and listener are paying joint-attention to a topic. Words must be organized in a way that directs attention from one point to another so that the shifts becomes meaningful. Generative grammar’s search for an underlying, common set of rules has been oblivious to the universal task of shifting attention.
Another benefit of the speech triangle doodle is that it give us something to look for in other animals when we ponder whether they are using language. Take vervet monkeys. They make one warning cry if they see a snake and another cry if they see a leopard. Is that a precursor to language? Like symbols, the cries have arbitrary meanings, so it might seem a step toward language. On the other hand it is nothing like a discussion of a topic. One vervet yells the equivalent of leopard. Other monkeys look around and when they see the leopard join in making the same warning cry. Soon the trees are filled with the chaotic racket of the jungle. Signals, yes. Speech triangle, no. Elephants, crows, parrots, dolphins… there may be another hypersocial species somewhere that pays joint attention to a topic. Or maybe not. But at least we have something concrete to test.
Meanwhile, I have been forced to notice that chimpanzees do not have a speech triangle. I had always thought of chimps as a very social animal. They live in groups, know one another as individuals, engage in some cooperative activities, and (Jane Goodall discovered) keep up family bonds. The absence of a speech triangle draws attention, however, to something they lack. They do not share information. Back in the days when captive apes were taught sign language, they could tell humans of their needs and would sign something’s name when asked. But they did not volunteer non-manipulative information to humans and did not ask their fellow apes to do something like pass the salt. They do not even have white eyeballs, making it harder to see where they are looking. It turns out that for all their sociability, chimpanzees are not given to sharing what they know. So there you have something even more fundamental to language than the words themselves—the urge to blab one’s secrets.
This approach also reduces the importance of several other matters. Symbols, for example, become secondary. Sure, words are symbols, but that is less important than their role in directing attention.
Again, this altered definition has radical implications. Much of the archaeology of language has focused on symbols and many people argue that if there were no symbols there could be no language. There could be no Shakespeare; that’s for sure, but how about the ability to say while pointing, “carcass yonder.” Homo groups could have been using words to direct attention to concrete things for a million and more years before they ever got around to inventing names for airy nothings.
I am getting on in years now, past the age where many a whippersnapper says a person can embrace new ideas. So it is particularly refreshing to have found that I can still toss out long-held axioms and make use of unexpected ones. Join me in the fun,
Never seen the speech triangle before! Great thinking!
