Responding to my earlier posting about affordances where I mentioned
Hutchins' _Cognition in the Wild_, Mike Cole writes:

I wasn't suggesting that Hutchins talks about affordances, pointing more to
his unit of analysis, functional systems. But yes, it is interesting that
he does not talk about "affordances". He clearly suggests that he sees
part of the structure that is propagated in the navigational fix cycle as
"in the world".

For example, on pp. 172-173, he notes that stars are natural, not
artifacts, but that they have structure and their distribution in the sky
(more or less random sprinkling, rather than uniform) makes navigation by
the stars possible. In talking about functional systems, he later cites
Bateson's example of the blind man walking with a stick, where again part
of the information is in the structure of the city. So does anyone have a
sense of why he does not mention Gibson and affordances?
