Well, that depends on your fucking ontological view, doesn't it? - I, personally, would say no, as I would define existence as being. A condition is a condition as soon as it's a condition, ya feel? And requires no outer relative (or supervenience) to define it, and regardless, Descartes was kind of stupid. I mean, plenty of people believe the opposite, the mind and the body are separate, blah blah binary bullshit. And plenty of people believe it is only against other beings or things or ideas that we can generate our own. I hold to that sometimes, but per a condition, I'd say no. Not if we're just talking fucking theory.
fwiw, I wouldn't give us a commonality, besides imagining fucking sand, of course. Higher thought is no more unique to us than what you termed 'the human condition,' implication or no. And what do you think? Do you think the one thousand people who lack imagination are lesser? As human beings, no. As members of a thinking community, as contributors to more than 'eat, shit, fuck, die,' yes.
Yes, the terms are fucking answer it, of course. And here I thought we were on the same page. Skip to chapter four.
