A child begins to speak; to say that it is hungry, or does not want to sleep. Where was the child’s language hiding before it began to speak? Did the child invent it?

Certainly not, experts on language development would insist. A child cannot create language. Language exists before the child starts to speak. All that is happening during language development is that language is being transported to the child.

The big question is: transported from where? There seem to be only two alternatives:

  1. Language is innate. It is prepared in our neural structures. When the child hears its parents speak, these structures are stimulated and soon start supporting the child’s own speech.
  2. Language is learned. It exists in society. Children have social learning skills; through these skills, language is transported from the social environment to the young pupil, soon supporting the child’s own speech.

These are the alternatives, then. Language is either inside or outside the newborn. Language development is either a process of “externalization” or a process of “internalization” of language. There can be no third alternative.

I have written about the ape Kanzi, who was raised by a human mother. I’ve written about him both on The Ethics Blog and in the book, Kanzi’s Primal Language. This bonobo and his half-sister Panbanisha developed language in a manner that does not clearly correspond to any of these two alternatives.

Since it is hardly credible that human language is innate in apes, ape language researchers typically try to teach apes language. These attempts fail.

Kanzi’s human mother, Sue Savage-Rumbaugh, avoided teaching Kanzi. Instead, she simply spoke to him, as parents do, in a shared Pan/Homo culture. As a result of this humanlike cultural rearing, he developed language as nativists believe only human children do: spontaneously, without the parent having to play the social role of a teacher.

The humble purpose of this blog post is to introduce the idea we have to think more carefully about human changeability than we have done so far. We tend to think that human changes are either lying dormant in our nature or are being taught to us by the society.

Kanzi entices us to think differently.

Spontaneous language development in a nonhuman suggests that being reared in culture is more than simply a matter of internalizing social norms. Being reared in culture means participating in the culture: a more creative and masterful role than that of a mere pupil.

I believe we are caught in an adult/child dichotomy. The creative role of the child becomes invisible because the dichotomy categorically portrays her as a novice, as a pupil, as a learner… as a vacuous not-yet-adult-human.

Perhaps, if we manage to liberate us from this dichotomy, we can see the possibility that language – together with much else in human life – is neither innate nor learned.
