Can computers think? Mapping the great debates

We stand on the shoulders of giants

“…so that we can see more than they, and things at a greater distance, not by virtue of any sharpness of sight on our part, or any physical distinction, but because we are carried high and raised up by their giant size.”

Robert Horn is one of my giants.

Twenty years ago, Bob looked at humanity’s troubled progress through the increasingly complex maze of philosophical, scientific, technological and political debate and realised that we needed maps.

But what kind of maps? What would they look like? What form would they take?

The way to figure this out, Bob reasoned, was to experiment with an extraordinarily complex debate. And he picked a spectacular one: the debate raging across philosophy, cognitive science, mathematics, neurobiology and computer science around the deceptively simple question “can computers think?”. A debate Alan Turing catalysed with his assertion in 1950 that by 2000:

“one will be able to speak of machines thinking without expecting to be contradicted.”

As with Orwell’s 1984, Turing’s date lies behind us now, but the issue has never been more salient for society.

Starting alone, and then with a team of researchers at Stanford, Bob devoured the relevant literature; distilling millions of words into the underlying arguments and iterating through multiple methods of presentation to develop a semantically rich and easy to navigate visual form.

The project culminated, in 1999, with the publication of seven remarkable 3’ x 4’ paper-based maps, encompassing more than 800 arguments advanced by over 300 of the finest minds of our generation, including: Alan Turing, John Searle, John Lucas, Herbert Simon, Douglas Hofstadter, Marvin Minsky, Daniel Dennett, Roger Penrose, Hilary Putnam, Stephen Kosslyn, Zenon Pylyshyn, James McClelland, Hubert Dreyfus, Ned Block, James Moor, Jack Copeland, Selmer Bringsjord, David Rumelhart, David Chalmers, and George Lakoff.

Robert Horn's Can Computers Think? Maps

(copies of the maps can be ordered here)

The set of maps is a masterpiece and an extraordinary gift to humanity; allowing anyone to gain a deep understanding of the structure and content of fifty years of intricate debate after a few hours of study rather than years of research. And it exemplifies the potential for maps of this kind to open other domains of debate and knowledge to general understanding.

At the time of publication, Robert Jacobson hailed Bob as “the new Mercator, a pioneering navigator of knowledge”—and, for anyone who has spent time with the set of maps, it easy to imagine that history will view its creation as a significant turning point in the advancement of human learning.

However, for all its astonishing brilliance, the set of maps also speaks to the challenges that remain in the field:

So what next?

What if you could lift Bob’s map off the page and recreate it online with all the arguments open to collaborative editing and evaluation by many people rather than a few; make the structure of the map fluid so that the debate can evolve as new arguments and evidence emerge; and allow related maps to interconnect so that, in principle, there is no limit to the territory that can be covered?

With Bob’s blessing, I am delighted to announce today that this is what we have done.

The top layer of the debate map is shown below: to open and explore the full map click on the View live button.

The translation will continue over the coming days, with more images and cross-relationships to add; however, the essence of the map is in place now and open to extension by anyone with an interest in the field.

If you would like to participate in this process, or the formal launch event next year, register online or contact me via the e-mail address above.

There’s more to discuss in future posts, including: the translation process, the expansion of the mapping approach to other fields, and the importance of the Can Computers Think? debate itself.

For now though, I’ll leave you with Bob’s map—and the view it affords from many tall shoulders.

Rethinking Drugs Policy

Following the publication of the report by the RSA Commission on Illegal Drugs, Communities and Public Policy earlier this year, the Debatemapper team worked with the RSA to create a debate map of the case made in the report for rethinking UK drugs policy.

The map decomposes the report’s arguments into constituent elements, each of which is open to further refinement, challenge, comment and evaluation. You can see the top level structure of the map in the debate strand below.

The Commission’s report is intended to feed into the UK Government’s 2008 review of the National Drugs Strategy; for which a formal public consultation process is underway. You can read more about the RSA’s other initiatives in this context here.

The debate map is now open to editing, comment and evaluation by anyone with an interest in the drugs policy field, and we hope that over time a community of experts will form around the map to cultivate it as a permanent resource for drugs policy stakeholders in the UK and beyond.

With the wider international debate in mind – and to illustrate how Debatemapper can be used to build clusters of interrelated maps – we have also created a new map from an existing strand of the RSA debate map, which explores the arguments for and against the legalisation of drugs.

The top-level arguments are shown in the strand below. Like a wiki, the debate map is inherently provisional and open to further refinement. So if you spot any gaps or weaknesses in the arguments or if you have any new lines of thought or evidence to contribute, please feel free to sign in and start editing and evaluating the map straightaway. Video and text help is available directly from the map.
