WE ARE ALL DESIGNISTS NOW:

Thoughts within thoughts make us human (Liz Else, 6/03/11, New Scientist)

Cogito ergo sum - I think, therefore I am - was coined by René Descartes in 1637. He was struggling to find a solid philosophical basis for how we know about reality and truth.

This is also turns out to be of the most famous examples of recursion, the process of embedding ideas within ideas that humans seem to do so effortlessly. So effortlessly and so skilfully, in fact, that it's beginning to look like the one true dividing line between animals and humans that may hold up to close scrutiny.

That's the hope of Michael Corballis, professor emeritus of psychology at the University of Auckland, New Zealand. His new book, The Recursive Mind: The origins of human language, thought, and civilization, is a fascinating and well-grounded exposition of the nature and power of recursion. [...]

So how did recursion help ancient humans pull themselves up by their cognitive bootstraps? It allowed us to engage in mental time travel, says Corballis, the recursive operation whereby we recall past episodes into present consciousness and imagine future ones, and sometimes even insert fictions into reality.

We are on our own with this degree of recursion. Chimps, bonobos and orangutans just don't tell stories, paint pictures, write music or make films - there are no great ape equivalents of Hamlet or Inception.

In the Beginning was the Word....
