This post shows how subjective and hard to define low vs high fantasy is. Merari is apparently unaware that Tolkien's Middle Earth is supposed to be our world thousands of years ago in a forgotten time. The whole "history becomes legend, legend becomes myth, and what once was is now forgotten" is not just about the story of the ring, but supposed to be talking about the whole Middle Earth world. Also, even though some main characters use magic, they are the exception and the vast majority of inhabitants of Middle Earth would use weaponry in the form of swords, axes, bows, etc. However, that Tom Bombadil character is definitely a strong argument for it being high fantasy.
Oh yes, I know that middle earth is actually our earth, just in a different era.
I did think of taking another example because of this, such as Terry Pratchett's discworld, but I thought Id better go for the more known example.
But take for instance Tanith Lee's books about the old gods. About 'when the world was flat, before it became round'
Arguably that also is low fantasy, because technically it is Earth. Though the circumstances, the rules, have changed so much that for all intents and purposes its a different world. Same with Tolkien, Id say.
While the actual fine tuning of low and high fantasy is debatable and sort of fluid, the literary definition is not.
And that is what I was referring too.
When all is said and done, the point I was trying to make is that 'high fantasy' does not mean surrealism or orcs or elves, it means a totally different world where our laws of nature are largely unimportant.
As opposed to low fantasy, wich does hold as a base reference our world with our rules, with fantasy injected into it.
A real good low fantasy for instance is 'I am legend' by Richard Matheson (book, not movie) in wich vampires are explained using real world physics and medical technology.
