Andrew Gallix ponders the purpose of intentionally difficult, almost unreadable books:
If literature cannot be reduced to the production of books, neither can it be reduced to the production of meaning. Unreadability may even be a deliberate compositional strategy. In his influential essay on “The Metaphysical Poets”, TS Eliot draws the conclusion that modern poetry must become increasingly “difficult” in order “to force, to dislocate if necessary, language into its meaning”. The need to breathe life back into a moribund language corrupted by overuse, chimes with Stéphane Mallarmé‘s endeavour to “purify the words of the tribe”. The French writer was very much influenced by Hegel, according to whom language negates things and beings in their singularity, replacing them with concepts. Words give us the world by taking it away. This is why the young Beckett‘s ambition was to “drill one hole after another” into language “until that which lurks behind, be it something or nothing, starts seeping through”.
