Heroes Not Zombies

Being There, by Andy Clark (ISBN 0-262-53156-9) is one of the most interestingly challenging books I’ve read for a long time. Let me say first that it’s taken me longer to read than I’d have expected it to. There are whole swathes of it which just didn’t engage me easily. In fact, a few times I thought I’d pack it in, then I’d come across a few sentences or a paragraph that not only would grab me and turn my thinking upside down, but it’d be exciting, visionary and, yes, down right thrilling.

I really enjoyed Robert Solomon’s, The Joy of Philosophy, not least because I feel he gave me a new vocabulary. His one word/concept of “thin” really expanded my thought. You can read more about it here, but what really excited me about this word was the way it captured the inadequacy of logical/analytical/reductionist thought.

I then read Barabasi’s Linked, which homed in on the key concepts of connections and nodes. I especially liked the way he demonstrated that the world, though a complex and at times chaotic system, is not random. Randomness turns out not to be the explanation for the phenomena we experience daily. That changed the way I thought about the world – there are patterns to be discovered, and phenomena to be understood. Sure, there is such a thing as chance, and life is often extremely unpredictable, but we can begin to unravel the connections between things and events, and in the process we can improve our understanding of the world.

Now I’ve just read Andy Clark’s Being There and he puts forward concepts that similarly change the way I understand the world and uses language in some novel ways which open the doors to other ways to explore life.  His main thesis is that to understand the mind we have to step outside of the study of the brain – not that the brain is not important of course – but we need to understand the environments in which brains exist. He draws the connections between the brain and the physical, social and symbolic environments in which we live and shows that to fully understand how the mind works we need to explore the interactions between brains and the world. He calls this concept of the mind, the “extended mind” and in the process he nicely shows how we use our brains primarily for pattern recognition and for creating change in the world. In particular how we create the structures in the world that we can then use to extend the functions of our minds.

Let me highlight one simple example – doing a jigsaw. To do a jigsaw we don’t work it all out in our heads but we use our hands to literally manipulate the pieces, turning them around to view each piece from different angles, so stimulating our pattern-recognising brains, and moving the pieces towards and away from different sections of the puzzle. In other words we manipulate the physical environment to help our pattern-spotting brains do what they do best, and to do that more quickly. Andy Clark nicely shows how we do exactly the same thing with our social environment and, crucially, with our ability to handle symbols and signs, which has reached its highest point in our development of language.

What does public language do for us? There is a common, easy answer, which, though not incorrect, is subtly misleading. The easy answer is that language helps us to communicate ideas. It lets other human beings profit from what we know, and it enables us to profit from what they know. This is surely true, and it locates one major wellspring of our rather unique kind of cognitive success. However, the emphasis on language as a medium of communication tends to blind us to a subtler but equally potent role: the role of language as a tool that alters the nature of the computational tasks involved in various kinds of problem solving.

I’ve never read this idea anywhere else – it highlights language as not only being a tool of communication but also being a tool we use to reshape the world to enable our brains to more effectively use their capacities.

This whole thrust can feel a little vertiginous. Look at this for example –

Every thought is had by a brain. But the flow of thoughts and the adaptive successes of reason are now seen to depend on repeated and crucial interactions with external resources. The role of such interactions, in the cases I have highlighted, is clearly computational and informational: it is to transform inputs, to simplify search, to aid recognition, to prompt associative recall, to offload memory, and so on…

and this –

Our brains are the cogs in larger social and cultural machines – machines that bear the mark of vast bodies of previous search and effort, both individual and collective. This machinery is, quite literally, the persisting embodiment of the wealth of achieved knowledge. It is this leviathan of diffused reason that presses maximal benefits from our own simple efforts….

Well, I don’t know about you but this embedding of the brain in the web of relationships, stretching backwards, sideways and forwards in time, makes my head spin! It turns the mind into an even more dynamic phenomenon than I had previously realised and at the same time it turns it into a much less isolated phenomenon too.
