I'm not so sure that horror should be dismissed as something less than literature.

I've got lots of books sitting here that have never been published because nobody could make any marketing sense of them.

Increasingly I felt as if I were entering a struggle that might even be more than life and death. It might be a struggle for my soul, my essence, or whatever part of me might have reference to the eternal. There are worse things than death, I suspected... so far the word demon had never been spoken among the scientists and doctors who were working with me...Alone at night I worried about the legendary cunning of demons ...At the very least I was going stark, raving mad.

I'm not so sure that horror should be dismissed as something less than literature.

In them was not the savage blankness of the reptile species. Instead there was something far worse - burning, unquenchable rage mixed with the self-mocking irony of great intelligence.

God is wild; I am tame....Night falls and an age ends....We call and are answered through the thick foliage, by voices too strange to be our own.

The truth is, everything ultimately comes down to the relationship between the reader and the writer and the characters. Does or does not a character address moral being in a universal and important way? If it does, then it's literature.
