Tim Parks, The Mind Outside My Head
Riccardo Manzotti is what they call a radical externalist: for him consciousness is not safely confined within a brain whose neurons select and store information received from a separate world, appropriating, segmenting, and manipulating various forms of input. Instead, he offers a model he calls Spread Mind: consciousness is a process shared between various otherwise distinct processes which, for convenience’s sake we have separated out and stabilized in the words subject and object. Language, or at least our modern language, thus encourages a false account of experience.
His favorite example is the rainbow. For the rainbow experience to happen we need sunshine, raindrops, and a spectator. It is not that the sun and the raindrops cease to exist if there is no one there to see them. Manzotti is not a Bishop Berkeley. But unless someone is present at a particular point no colored arch can appear. The rainbow is hence a process requiring various elements, one of which happens to be an instrument of sense perception.
