Rather than a series of levels, we have a distinguished level, , the level at which interpretation of the… — Zenon W. Pylyshyn

[If] we equip the programmed computer with transducers so it can interact freely with a natural environment and a linguistic one, as well as the power to make inferences, it is far from obvious what if any latitude the theorist (who knows how the transducers operate and therefore what they respond to) would still have in assigning a coherent interpretation to the functional states so as to capture psychologically relevant regularities in behavior. If the answer is that the theorist is left with no latitude beyond the usual inductive indeterminism all theories have in the face of finite data, it would be perverse to deny that these states had the semantic content assigned to them by the theory.

[A computer program for Task A qua an explanatory model and how a human cognizer actually carries out Task A are equivalent in the strong sense when it can be shown that]... the model and the organism are carrying out the same process.

The term knowledge raises philosophical eyebrows (strictly speaking, it should be called belief).
