How so? Would internalizing and understanding the color of the sky prevent him from exploring?
I would argue that the color of the sky does matter because all of the other reactions described are realistic reactions, and the shape of their society will be altered by this new information. It’s possible that any other discovery he makes on the surface will never actually come to be appreciated or used by the rest of humanity as they fight while he’s in the wilderness if he doesn’t take into consideration what will happen when others see the sky..
Ferris definitely had the most pro-science reaction. I worry about drawing conclusions about the “best” approach out of these archetypes. Ferris is the one that doesn’t think for a moment about the societal impact his discovery will have. That’s OK, but it’s not necessarily a good guiding principle for behavior. Everyone depicted had realistic reactions that would be viewed as better or worse by different groups.
I’m not saying that you’re wrong—at all. My very first reaction was that Ferris is “right.” But I think which one we think of as “right” says a lot about our existing values.
