sometimes supposes that the mosaic world of
primitive art or even the world of Byzantine art, 
represents a mere difference in degree, a sort of 
technical failure to bring their visual portrayals up 
to the level of full visual effectiveness. Nothing 
could be further from the truth. This, in fact, is a 
misconception that has impaired understanding 
between colored and white societies. There is a 
very large stake in proper understanding of the 
differences in our sense orientations affected by 
technological extensions of our bodies and our 
nervous systems.
