Embodied Intelligence

20111119-181205.jpgWhy is an octopus smarter than a snail? Same family, same squishy body. Yet one is entirely predictable, the other spookily individual. Is it ‘in’ their bodies?

Having reflected on the ’embodied intelligence’ in a strawberry last week, I read that some Roboticists are moving on from the clever brain/dumb body ‘central processor’ model. Powerful chip-sets and nuts and bolts are being pushed aside by inherently ‘clever’ squishy limbs and appendages better adapted to their task.

Why pick up a fragile glass with a big clunky metal hand, when a rubber bag filled with coffee grounds, attached to a vacuum pump, morphs perfectly to the job?

Embodied intelligence is an interesting thought. Millions of years of evolution mean my leg swings naturally forward and lands in front of the other when I walk. The brain has very little to do. The ‘intelligence’ is largely designed in. Aquinas would recognise this – for him our bodies, like our emotions, are a full part of our ‘reason’.

The matter arising is, are octopuses smart because they evolved a big brain – for the joy of contemplation, communication, complex waving and changing colour? Or does an eight legged body (actually two ‘arms’ and six ‘legs’) mean high intelligence ’emerges’ as a bigger brain develops in response to increasing bodily complexity?

It’s all a bit simpler for a snail – A to B at a foot per minute. Perhaps that’s why they’re a bit simple. The surest predictor of animal brain size is body size. I wonder whether complexity of motor skills and sensory apparatus isn’t a big driver too.

What does it mean for us? First our intelligence is ’embodied’ in quick fingers, rapid eyes and sharp ears. Perhaps also what it means, is we aren’t Cartesian ‘ghosts in machines’. We aren’t software and hardware. We are completely integrated ‘wetware’ – like an octopus, as much arms and legs as big brains.

So if we want to build smarter tools and helpers, and understand ourselves better, inspiration from nature – not Fritz Lang – is the answer.

Strawberry

20111113-150850.jpgI’ve discovered Philosophy Now via Kindle. And a find it is too. This month’s edition delves into the Philosophy of Mind which I studied twenty odd years ago. What’s new? Quite a lot. But, also, quite a lot is not.

Neuroscience is the new 200lb gorilla on the scene. Is philosophy, contemplation and introspection irrelevant when you have brain scanners and MRI? The argument cuts both ways. Reductionism says its a simple case of describing something complex. I used to agree, now I’m less sure.

Before cosmology we harboured intuitive, and often mystical, beliefs to explain sun, moon and stars. Then telescopes were invented and we moved on to facts and evidence. Aristotle imagined ‘biles and humours’ drove the body, until medicine discovered intricate circulatory and nervous systems. Reductionists say we’ll get over our belief in ‘consciousness’, ‘intentions’ and ‘ideas’ once the science advances enough to describe ‘brain states’ better.

The alternate thesis – much more where Aquinas, Kierkegaard and Nietzsche might land – is that describing a TV’s wiring misses what’s on screen. The ’emergent phenomenon’ is a living feeling being, living a unique life, intimately connected to other living feeling beings, all equally unique but interdependent with each other.

It comes down to complexity in the end. A computer or iPhone full of data apparently weighs fractionally more than an empty one. But it is only fractionally more. I read the entire ‘weight’ of data contained in the Internet could easily be stored in the mass of a strawberry. But the ‘knowledge’ exists in myriad computers, data centres and browsers interlinked with myriad minds.

In one way a strawberry already contains a nearly perfect dataset to describe humans. In its DNA it describes carbon-based life, an oxygen rich atmosphere, the rise of flowering plants – and who knows, maybe, some clues to cultivation. It is already bursting with data, just of a ‘natural’ flavour.

And this is the point for me. Let’s imagine we could load the entirety of human culture, knowledge and experience into a strawberry and fire it into space. Billions of years on, when our planet has long since expired, suppose an alien civilisation finds it. From which would they learn more about living as a human being – reading the data locked in the atomic structure of the strawberry, or simply eating it?

Of Angels

20111105-201745.jpgSmarting from the accusation I seldom read the source, I’m wading through Aquinas at present. Corblimey he’s obsessed with some things well beyond my interest. But that’s because I’m reading him for his ethics, and he’s writing a science book as far as he’s concerned.

Summae Theologica is, I come to realise, describing Aquinas’ views on how the world, universe, animals, minds, substance and energy all work – the lot.

Not surprising then he spends considerable time on causation – what causes what, what is primary, what is secondary and what is ‘higher’ and ‘lower’, what is an ‘operation’ what is a ‘state’.

His method is famously rigorous: three or four well sourced views on a theme, his own judgement and an answer to the opening views.

I think he quite carefully integrates a humanist perspective with a religious one. At times he acknowledges tantalisingly what ‘would’ be the case if there was no God – Aristotle ‘would’ be right on human happiness for instance he says.

After Aristotle, he concurs that our ‘end’ is indeed happiness. But we achieve happiness imperfectly in our mortal lives. We achieve it most in contemplation. In contemplation of what though?

For Aquinas, of course, that would be God. But contemplation of God is, he acknowledges, tricky. Not least as He is infinite and Our reason is finite. We’re snookered from the off.

What to do? It could be worse. Animals are even further from God than we are. They lack our intellect and capacity for reason and thought and so can’t contemplate God at all.

Aquinas explicitly acknowledges that nature has fitted us and animals with desires and emotions to further our own survival and that of our species – positively Darwinian. But they are ‘beneath’ us and we are a rung down from – you guessed it – Angels.

God tops Angels of course, but each in the chain comes closer to ‘perfection’ and achieves ‘happiness’ most by ‘touching’ the one above.

I’m not sure how many farm animals would agree they are ‘perfected’ and happier ‘touching’ humans. Perhaps a well trained sheepdog. But we humans can attain greater happiness in the use of our more ‘perfect’ power, namely contemplation. And among the things we can happily contemplate are Angels.

Now this is a thought I can honestly say I have never had. Beyond the one on top of the Christmas Tree and my daughter in the school nativity, I have never spent any time contemplating Angels. Perhaps I should?

But the point I take from Aquinas and Angels is this: contemplation, seeing beauty around us and perfecting and developing our human capacities, skills and aptitudes is where Earthly happiness lies.

Csikszentmihalyi comes to mind. As I said to someone last weekend it’s all about adding ‘relevant complexity’ to our lives and personalities.

And I think this is what Aquinas is getting at too. A life of virtue, self-improvement and integration of the body, soul and mind might mean at the end of it all, the ‘bottled essence’ of us – probably in frail and wizened form – is a shimmering soul ‘touching’ that of an Angel.

In Praise of ‘Prudentia’

20111028-170621.jpg

The virtue of ‘Prudentia’
In Aquinas’s teaching,
Is ‘practical wisdom’ in
Choice and decision.

It’s a Bayesian thing,
Not just logical stages.
Which a life of experience
And virtue engages.

Grounded in reason
But felt in the boots,
You can’t teach Pudentia,
We must find our own routes

Each person’s is different,
Our wisdom’s our own.
When we try to describe it
The words struggle to form.

But don’t deconstruct it,
The details mislead.
If you try to explain it,
Confidence bleeds.

Invest in Prudentia.
Your gut’s not often wrong.
Thought, experience, emotion
In symphony belong.

I’ve spoken in praise of ‘Prudentia’ twice today. The first time was inviting someone to really use their ‘practical reason’ in designing something. That meant acknowledging complexity, personalities and what we’re trying to do – and really, based on their experience and judgement, coming up with something that has a fighting chance of working.

The second was in acknowledging and appreciating a way forward I’d not thought of. On the face of it I had ruled it out, but on reflection it had a good deal to commend it.

Not everything in life is rational, simple or binary. As someone said to me yesterday, probability is rarely 0 or 1. ‘Prudentia’ is our Bayesian gift for dealing with complexity – practical wisdom.

Philia

I do feel – and feel is the right word – that Herbert McCabe’s ‘On Aquinas’ deserves a wider audience. So many important themes, from so many thinkers, rendered limpid in a thesis all of his own.

Of course there’s Aristotle in there. And as the title suggests, we are constantly accompanied by Aquinas. But, for me, it’s Herbert McCabe who shines through as having put together his own picture of what constitutes the human condition, in what I’d take as a summation of his life’s work.

I noted yesterday that people read more pulp fiction on Kindles than they’d dare have on their bookshelf or be seen reading in public. But the opposite is also the case. Truth is I’d never have found Herbert McCabe or bought his book without the web, connected devices and impulsive instant gratification via electronic delivery.

McCabe makes a powerful case for ‘philia’, mutual care and fellow-feeling, as the right basis for our relationships – not the functional rights and duties of justice and the law.

Justice is the minimum duty we owe to ‘strangers’, ‘philia’ is the care, respect, love, friendship, reasonable accommodation and interdependence we have with other people which constitute ‘humanity’ and ‘society’. Laws imperfectly capture the statutory minimum, ‘philia‘ is the gold standard for people, politics and society.

Stood on a grey suburban station platform this morning (the car’s bust again) I looked at the different shapes and sizes of punters, mums and pinstriped professionals all focused on getting their train. There were moments of ‘philia’. A shy ‘See you tomorrow‘ to the man serving a women her daily coffee, a jolly exchange between Ticket Collector and middle aged vamp.

Through the lens of ‘philia’ people look different. We judge less, tolerate more and look beyond face value. McCabe was right to remind us of this.
