How the Concept of Affordances Has Evolved
Recently, I had the chance to realize how quickly a concept can change—in this case, the concept of affordances, In its original form, this concept first appeared in studies by James J. Gibson on the sense of sight, in the 1970s. In short, Gibson observed that when we see an object, what interests us the most is not so much its physical properties as the opportunities that it affords us to take action—to intervene more effectively in the world and thus better resist the ravages of time, or, in the elegant language of physics, to temporarily overcome the second law of thermodynamics, that entropy always increases.
For some years, this concept of affordances received little attention in cognitive science, because the prevailing highly computationalist paradigm, emphasizing inputs, manipulation of symbols, and outputs, militated against its full development. This is a common phenomenon in the history of ideas: a conceptual innovation that is just a bit ahead of its time does not fit into any existing, broader paradigm that would let the scientific community understand and embrace its full implications.

Why You Are Not Just Your Brain
In the introduction to their 1991 book The Embodied Mind, Francisco Varela, Evan Thompson, and Eleanor Rosch noted that as of that writing, the cognitive sciences had little to say about what it means to be human in the concrete situations of everyday life. This criticism was aimed directly at the prevailing paradigm, according to which the human brain worked somewhat like a computer, with input, information processing, symbolic representation, output, and so on.
In contrast, the approach proposed by Varela and his colleagues, to which they gave the name “enaction”, emphasizes how much our reasoning depends on our bodies and on the environmental context in which they are situated. (more…)
