I have a trial tomorrow and not enough time to truly ponder your thoughts, but
here are my first impressions.
I would prefer to stick to LotR and treat The Hobbit as a separate work.
It can be exciting to compare and contrast the two, but I do think they stand
alone and have many differences in style and purpose.
So your examples from LotR are Sam and Aragorn (feet in both worlds), Boromir
(old world), and Saruman (modern). But what about the other people of
Gondor and Rohan, or the elves of Lothlorien? Surely they (least of all
the elves) are not in any significant way modern?
And indeed the better hobbits -- those who do not later league with Saruman --
are not modern in the sense that Tolkien despised. They are quite
conservative, and do not hold with change. They still follow the King's
Rules even though there has been no king for 1000 years. But they follow
tradition out of habit, not out of knowledge. And in many cases that
means they don't hold with anything different -- even if positive.
Isengard and Mordor do not engage in mass production of anything but orcs, and
orcs are not machines. Barad-dur, in particular, and the flaming Eye, And
Mordor, and Minas Morgul, and the valley below, and the Nazgul, all have a
certain evil beauty to them. They are not evil and mundane like the robot
factories Tolkien hated.
At the beginning and end of LotR the Shire feels very much like rural England
at the end of the 19th century, before the introduction of cars. As the
hobbits leave the Shire the settings feel gradually more ancient, with
Lothlorien the most ancient of all. And when the hobbits come to Rohan,
Gondor, and Mordor, the settings continue to feel ancient in human terms, but
not in elvish terms. The hobbits retain their modern vernacular but are
schooled in wisdom more ancient than human history. Aragorn moves
smoothly between both worlds. But the war between Rohan and Saruman or
Gondor and Sauron is not a clash of the modern world with the ancient. It
is a clash that takes place as the last age of the elves comes to a close and
the first age of men begins.
The machines of the robot age are in some ways far more insidious than those of
LotR, for they are mass-produced until they blot out the landscape, and yet
always introduced as benefits to mankind. Electricity, cars, cheap
housing -- none of them are intended to kill, maim, or enslave, and yet they
have done more to destroy the wilderness than any army. Whereas none of
the machines used by Saruman differ much from those used by the Romans.
The hobbits stay in their 19th century rural vernacular, like first-time time
travelers. Aragorn takes on the vernacular of the land he is in, like an
experienced time traveler. But the people of Rohan and Gondor keep the
ancient forms whether they are good, bad, or wavering.
So I'm sorry, but I don't buy it. I don't think any part of LotR
resembles the 20th century. And I especially don't think any part of
Middle-earth south of Moria resembles anything more modern than the
Middle-ages. Indeed I think the whole point was to escape the 20th
century entirely.
This is still rather random and not thoroughly thought through, but I don't
have time to ponder it any more. And because of my trial I don't have
time to reply again. But I will look at this again in three or four days
and see what you have said.
If I have been less than tactful in any way, please forgive
me.
