  The previous discussion of dynamic cognitive science serves also to illustrate the Constitution theme. As the quotation above from Spivey indicated, dynamically-oriented cognitive scientists regard cognition to be the product of interactions between brain, body, and world. The continuous interactions between these things, Chemero writes, explains why “dynamically-minded cognitive scientists do not assume that an animal must represent the world to interact with it. Instead, they think of the animal and the relevant parts of the environment as together comprising a single, coupled system” (2001, 142). Chemero continues this idea: “It is only for convenience (and from habit) that we think of the organism and environment as separate; in fact, they are best thought of as comprising just one system…the animal and environment are not separate to begin with” (2001, 142).
