We agree that no nontrivial story is possible within a direct encoding interpretation of Gibson, but will show that such a story is possible, and is in large respects already contained in Gibson's writings, for an interactive interpretation.

Another way to see this is to note that if such disruptions can be ruled out as invalid, if the transducer only exists or only functions under 'normal' conditions, then the if P then Si generalization is no longer counterfactual supporting, but is only valid across employments of the method of differences (the altering of normal correlational relationships) that do not alter the normal ecological conditions and relationships. But, of course, under normal ecological conditions, the layout is correlated with internal states, and the layout-to-internal state relationship remains unchanged so long as such normal conditions remain unchanged.
