DH: “Color can speak volumes. … Color is a window into fitness - also a jailhouse. … Try to imagine a color you’ve never seen. Can’t do it. … Color… like perception, is both window and prison.” (¶1)
Polychromy = “the art of painting in several colors, especially as applied to ancient pottery, …”
We could also say that our bodies are the prison of our mind. If you really wanted to look at it that way. But, what’s it get you? Beyond a reflection into your own psyche?
A review of Donald Hoffman’s, Case Against Reality,
Chapter 8, Polychromy - Mutations of an Interface
DH: “As a window on fitness color is not flawless, just adequate to guide our actions that keep us alive long enough to reproduce. Color, like each of our perception, compresses the complexities of fitness payoffs to bare essentials.” (¶2)
What gives Hoffman the right to expect some subjective idealized flawlessness from nature? Seems a bit hubristic to me.
Sure color perception is an important element, among many important sense “elements,” none of them perfect in the best of times, all vulnerable to a galaxy of pathologies and quirks. Such is life. That’s why luck often matters as much as fitness.
The fundamental problem with Hoffman’s narrative is that he keeps blaming the perceived object for the quirks and short comings of the perceiving instrument. It’s silly.
DH: “(The human eye has 7 million cones and 120 million rods, each carrying compressed information. The circuitry of the eye then squashes this down to 1 million signal and forwards it to the brain, which must correct errors and decode actionable messages about fitness.” (¶8)
Thus optical illusions happens. I’m going to skip paragraphs worth of Hoffman’s tour through optics trivia. I’ll share trustworthy authoritative sources and let them explain the details without Hoffman’s tactical omissions.
