A certain indeterminacy of color, neither cerise nor taupe nor burnt umber, nor gray either
Fragments from Eric Schwitzgebel’s Why did we think we dreamed in black and white? Prior to the rise of scientific psychology, scholars interested in dreaming generally stated or assumed that dreams have color. For example, Aristotle specifically includes colors among the remnants that sense-impressions may leave in the sense-organs and which thus appear to us […]

A system for detecting an accessible bug
We have described each of the operations on the retinal image in terms of what common factors in a large variety of stimuli cause response and what common factors have no effect. What, then, does a particular fiber in the optic nerve measure? We have considered it to be how much there is in a […]

“As I recovered at home, colour started slowly creeping back into my life, whispering around corners. This was a very perplexing time, for often I only felt I was seeing a colour but was unable to identify it. I would stare endlessly at trees and lamp-posts, desperate to match the colour I believed was there […]

If we are to avoid the problem of creating a visual system that will reduce the capacity of the eye, it is necessary to disassociate the video camera from the eye and make it an extension of the room. Peter Campus Video as a Function of Reality, 1974
This divine scanner
In How One Sees, Siegfried Zielinski and Franziska Latell trace the genealogy of vision. Quoting the philosopher Abu Nasr Al-Farabi (870-950), the authors write: Optics teach “according to the true circumstances of what is looked at to find the matter, the quantity, form, position and order and the other things which of the things is […]
