I think maybe it's an oxymoron to talk about conceiving what something looks like outside of perception. I predict you'll disagree with this, but I stick to my guns that for there to be similarity (or even definable qualities) of "somethings" you need to have a specific perspective from which you are looking at them. I don't think we can sensibly talk about how something appears when no one is looking at it.

Okay - I think here, we're actually confusing each other. By saying Jupiter is a human concept, I didn't mean that other non-humans couldn't have a similar one. I actually meant that it's a precisely defined concept with specific boundaries and qualities attached - as in the cat example last time, there is no precise "Jupiter-object" in reality - it's a useful concept, and aliens may well articulate their experience of reality into a very similar concept...but there's no precise Jupiter out there, because reality doesn't have the kind of precisely delineated objects our language imputes. Th real problem is that the more precisel;y we try to define our words and concepts, the more slippery reality becomes. This is <i>not</i> to say there's not something that correlates with the word. As I've said before, I'm neither realist nor anti-realist. I think the binary involved here doesn't do justice.
But, this discussion of Jupiter I think is taking us further and further away from the initial issue, which was of Napoleon - and I think it's here that my point is much more useful (to be frank, in regards to something like Jupiter it's really rather a trivial point). What have you to say in this regard?

I refer you to cybernetics here. While observing Jupiter, you and Jupiter become part of a single system. While admitting the utility of it, I disagree with the skin-barrier of identity (this is probably clear by now). I don't claim to draw any distinct boundaries between the observer and observed. (This is also probably by now apparent)

Okay. I'll wait for you to offer either an argument or some evidence for why this is the case ;) (Still though, for as long as we're talking about other subjectivities note that this makes no real inroad into the question of objective identities/properties)

Can you offer a means for doing this?

Not necessarily. And planets aren't the only source for intelligence to develop (at a fairly extreme - though not the most extreme - point, take Boltzmann Brains as an example)

Hmm, not necessarily. I'm saying we've developed a particular kind of awareness/conceptualisation which happens to have worked. The fact that everything in the "Earth" system has roughly the same kind of objective concept-structure would be pretty much determined by our evolutionary lineage, and our interpdependent integration as a system.
