Octavio Paz, On Poets and Others:

Even “having no meaning” is a way of meaning. The absurd is one of the extremes that meaning reaches when it examines its conscience and asks itself, What is the meaning of meaning? Ambivalence of meaning: it is the fissure through which we enter things and the fissure through which being escapes from them.

Meaning ceaselessly undermines the poem; it seeks to reduce its reality as an object of the senses and as a unique thing to an idea, a definition, or a “message.” To protect the poem from the ravages of meaning, poets stress the material aspect of language.
