Talking is just recording what you're thinking. It's not the thing itself. When I'm talking to you some separate part of my mind is composing what I'm about to say. But it's not yet in the form of words. So what is it in the form of? There's certainly no sense of some homunculus whispering to us the words we're about to say. Aside from raising the spectre of an infinite regress—as in who is whispering to the whisperer—it raises the question of a language of thought. Part of the general puzzle of how we get from the mind to the world. A hundred billion synaptic events clicking away in the dark like blind ladies at their knitting.

OK, so let’s take some stock of where we’ve been thus far in our explorations of the development of language and literacy.

We’ve spent some time poking at the notion of whether learning to read is unnatural or not, and landed on the conviction that terming it unnatural–though useful as a rhetorical device–may be less precise than recognizing that learning to read and write is more formal, abstract, and distal from the immediate context of human interaction – and thus requires more effort, instruction, and practice to master.

We then turned to the development of language and discovered that even here–despite the ubiquity and swiftness with which native languages develop anew in every child across our species–language may not be as innate and inborn as it may appear.

Both language and literacy have bestowed humanity with sacred powers for the transmission and accumulation of cultural knowledge that seems to–as of yet–have no ceiling beyond that of our own destruction. Whether this is natural or innate or not may be beside the point. What does seem to be clear is that we have something inherited within us that is unfurled and reified by the networks that are riven across our brains through storytelling, interactive dialogue, and shared book reading that connects spoken to written language, and further strengthened with the hardwon fluency we manage to achieve on our own across modalities, texts, and languages.
