you are reconstructing a space from the body-experience of an other. The image has forced out the body (the subject) and its knowing subjectivity.
'We can say "body of knowledge"'
1.Written language (not spoken) obscures the speaker because it is a voice that survived the finite organism to become ominiscient, disembodied, and enduring.
2. Knowledge cannot have a body but we can grant it a symbolic one.
In spoken language, phonemes are also abstract and meaningless, but they do not exist in 2D space. There is a distinction between image and graphic. Scaleable graphic/2D/drawing requires no external data. Rendered image/picture is an analog representation requiring external data.
What is unrendered is unaccessed knowledge. What is unrenderable is unavailable knowledge.
