The From the home of the co-breakers and the birthplace of modern computing, this is the Bletchley Park podcast.

This is M.C. Fontaine, welcoming you to another Bletchley Park podcast Extra.

We again return to the Turing Education Day.

This week's talk is by Baroness Susan Greenfield.

Linking in with both Turing's work in computing and artificial intelligence,

it's titled How Brain Power Goes Beyond Computer Power.

You might wonder why I'm actually here because I stand before you, unashamedly as a neuroscientist.

I know very little about computers, but what I do know is that there are questions that neuroscience is posing that may be of relevance to the people in this room, that may be of interest both in measuring up against the checks and balances of what computer science has succeeded in or not succeeded in answering, but more excitingly in the future, what might be the issues where we can interface between

computational science and neuroscience.

The area that I think is one of the most exciting, and the one I want to cut to straight away,

is the one that really no science, irrespective of your discipline, has come up with, in my mind, a convincing

approach to resolving, and that is the issue of consciousness.

Now we could try and wrestle around on refining consciousness.

That's very difficult because normally when we define something, we use an operational definition,

such as flight is when you define gravity, or we use reference to a higher set,

such as a table is a piece of furniture, love is an emotion, consciousness is a what?

There's no higher set.

So normally we stumble around trying to define consciousness,

but can I be very unscientific and say we all know what consciousness is, don't we?

It's what you're going to lose tonight. And I know this will offend philosophers hugely.

If you're aniseatized, it's what you lose.
