And it slips through our fingers

[Eomer of the Rohirrim]

The diminishing of things is one aspect of Tolkien's stories that has always fascinated me. The idea that things generally get worse or weaker over time certainly makes for less happy endings. It adds to the tragedy. There are numerous examples: the decline of Middle-earth in general; the Elves; Numenor; the race of Men; the Hobbits and the Dwarves. The zenith of their greatness was reached fairly swiftly - maybe Numenor was more complex - and the descent to the (perhaps illusionary) nadir took a much longer time.

I would particularly like to know if this theme is ultimately religious. I know almost nothing about Catholicism, Christianity or religion in general. Is it anything to do with the Garden of Eden?

What it does do is go against a staple of Romanticism or the Enlightenment, namely that human achievment, wisdom and greatness keeps increasing.

Any thoughts? As I suggested, I can hardly bear to imagine a Middle-earth with lots of happy and glorious endings. It wouldn't be right.
