"No one , to my knowledge, has suggested that the image must accelerate and decelerate or that the relation among torque, angular momentum, and angular velocity has a,1 analogue in the mental rotation case. Of course it may tum our that it takes subjects longer to rotate an object that they imagine to be heavier, thus increasing the predictive value of the metaphor. But in that case it seems clearer that, even if it was predictive, the metaphor could nor be explanatory ."

“What people report is not properties of their image but of the objects they are imagining. Such properties as color, shape, size and so on are clearly properties of the objects that are being imagined. This distinction is crucial. The seemingly innocent scope slip that takes image of object X with property Pro mean with property P instead of the correct image of is probably the most ubiquitous and damaging conclusion in the whole imagery literature.”

“... the model and the organism are carrying out the same process.”

“The term knowledge raises philosophical eyebrows .”

“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 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.”

“Rather than a series of levels, we have a distinguished level, , the level at which interpretation of the symbols is in the intentional, or cognitive, domain or in the domain of the objects of thought.”
