One step further and I thought of the theme of isolationism in regard to hobbits and Ents. Both are reluctant to involve themselves in the world outside (“The wide world is all about you: you can fence yourselves in, but you cannot for ever fence it out” to quote Gildor), isolating themselves in their safe spaces of the Shire and Fangorn, respectively. They both wound up being part of greater events in Middle-earth, both contributing to the defeat of Saruman, but only reluctantly when there was no other choice (The Last March of the Ents; see below) or when prompted by others to act (The Battle of Bywater).
- (Treebeard) Treebeard, The Two Towers'But if we stayed at home and did nothing, doom would find us anyway, sooner or later. That thought has long been growing in our hearts; and that is why we are marching now. Now at last the march of the Ents may be worth a song. Aye’, he sighed, ‘we may help the other peoples before we pass away.’
There are other isolated or hidden communities (Gondolin and Imladris come to mind though they are not quite as cut off from the world at least to my memory) in the Legendarium but the difference to me is that those were hidden by need to survive/outlast the Enemy whereas hobbits and Ents sort of closed themselves off by choice (though I suppose one could argue Ents were pushed into it by the destruction of the great forests so they could only find sanctuary in Fangorn).
This hasn’t been super well thought out as you can see, but I thought it might potentially start some interesting discussion. I guess I also wonder if this was at all intentional on Tolkien’s part, to comment on the pitfalls of isolation.
