Would you care to shift universals with RWP and try pi or threeness?

For the record: you shifted universals. I took that as a concession that you're no longer claiming green is a universal. If not, let me know, and we can discuss how loose the criteria for a universal can be.

Thank you for your reply!

Er, we went from "greenness" to "pi" or "threeness" etc. after your post at 283 where you objected to "greenness" as an example. You said:

Out of this infinitiy of objective colors people and most organisms can see only three, or two, or just one. And ultimately, it all comes down to a function where we have intensity of light on one axis and frequency on the other. But even that function can be shifted, for example, by the Doppler effect.

It's not a very good example of a universal.

It's fine with me to go back to "greenness" as an example of a universal. To support that green exists apart from the observer, I just asserted a link to js1138 in my post at 367 - which you might want to scan before we resume this debate this evening.
