  Clark and Toribio (1994) describe some cognitive tasks as “representation-hungry.” Examples include imagining or thinking about non-existent entities (e.g., unicorns) or counterfactual states of affairs (what would happen if I sawed through the tree in this direction?). Of necessity, an organism cannot be in constant contact with non-existents. That human beings so readily and often entertain such thoughts poses a difficulty for enactivists like Chemero and Hutto and Myin who see in Brooks’s “world as its own model” slogan a foundation for all or most cognition. Because the world contains no unicorns, using the world as a model cannot explain thoughts about unicorns.
