Attentive selection penetrates (almost) the entire visual system

Pylyshyn claims that if a system is cognitively penetrable, its function de pends in a semantically coherent way to the organism's goals and beliefs. B e rejects evidence of attentional modulation observed in neurons within the visual system, claiming that any modulation seen is not logically related to goals and behavior. I present some of this evidence and claim that it is connected in exactly the way Pylyshyn requires and thus it refutes his mai n thesis.
