That is a remarkable way to put it. But aren't has functions -- per definition -- n-to-1? That seems to be what the perceiving function is about: map multiple sensations into a single correlated perception.
To my mind, an ~n-to-1 mapping would actually be a bit more like idealistic Platonic classifying than Wittgensteinian perception (~"we spin perceptual threads by twisting n attributes like fiber on fiber. And the strength of the thread does not reside in the fact that some 1 fiber runs through its whole length, but in the overlapping of the fibers.").
What do you think? :)
