James Gibson’s theory of affordances suggests that what animals perceive in their environment is not so much the properties of individual objects but rather the possibilities for action they enable. There’s a sense here that what things are and what things mean show up for the animal at the same time. On Gibson’s view, an ecological niche is thus best understood as a set of affordances made available by an animal’s capacities. For example, a niche may afford climbing, sheltering, swimming, running, standing, eating, and so on.
Gibson notes that there’s a tight link between animal and niche, where the abilities of the animal and the properties of the niche mutually act to constrain the set of available affordances. In the case of humans, Gibson observes, the situation is a bit different in that we actively engage in the planned construction of our own affordance landscapes. (Had Gibson been alive today he no doubt would have paid greater attention to the niche-constructing actions of all organisms.) We can see a gymnasium as affording fitness, a town square as affording meeting, a library as affording reading, for example. Continue reading
It’s been just over a year since I posted anything new here, but that’s not for lack of study or engagement on my part. Work—both intellectual and vocational—continues apace. Readers may be interested to know that I’ve started pursuit of a PhD here in the San Francisco Bay Area. Below I’m sharing a short description of my plans for the dissertation. Things may change a bit here and there as I complete various sections of the dissertation, but I expect to follow pretty closely the below summary. I’m not sure what will become of Knowledge Ecology at this point. I may start afresh with a new blog. I may continue blogging here. I might abandon the Internet all together. Who knows.
The thing about blogging—both positive and negative—is that it puts on offer a continuous stream of output, an ongoing account of one’s thinking and development. This has the double effect of providing greater context for one’s writing but also makes it difficult, at least psychologically for me, to separate oneself from earlier work in the way that writing books or articles naturally provides. The Internet tends toward a pathological amount of continuity and interconnectivity that I think many of us writing in this medium would be wise to rail against. In any case, enjoy the PhD ruminations.
