Remarks on Color

Why do people find it intuitive to describe this kind of very powerful simultaneous color-contrast effect as an "illusion"? After all, the look of a color against a white background depends just as much on its background as the look of the spirals in the example depend on their background.

Here are some more simultaneous color contrast "illusions" from the same source as the first one.

Metamers seem to present a problem for physicalist theories of color. Make some yourself.

Another blow to the reliability of the inference from "I can't imagine the possibility of p" to "p is impossible": it might be possible for something to be simultaneously green and red all over.

Take a color discrimination test.

Metaphysics Mix Tape!

Muxtape is "sort[ing] out a problem with the RIAA", so this will be just be a metaphysics-themed list of songs, with no Muxtape link. But it adheres to the convention of being limited to twelve songs. The list touches on themes of universals, objects, change, time, personal identity, numbers, possibility, necessity, and free will.

Track List:

1. Universal - Blur
2. Object - The Cure
3. Something - The Beatles
4. Nothing's Changed - The Zombies
5. Cause = Time - Broken Social Scene
6. Back in Time - Prefuse 73
7. Half A Person - The Smiths
8. Time And Place - Lee Moses

10. Possibilities - Papas Fritas
11. It Ain't Necessarily So - Mary Lou Williams
12. Free Will and Testament - Robert Wyatt
