I'm pretty new to the semantic web and perhaps I miss something here, so please forgive me if this is a stupid question, but:

Why don't we create - lets say a wiki - at for example www.abstract-concepts.org or something like that and put alle the abstract concepts like love, friendship, war or whatever on pages there. So you could write a little definition for each (and people could add something - hence the wiki) and everybody could use the URIs there. Perhaps we could even use wikipedia for that?

I understand that this is a little bit different from the concept of "Person named Tim Berners-Lee", but it would at least give us something for the more general concepts, wouldn't it?
