So dematerialisation is connected with orgasm/womb sort of language because you're re-physicalising the language about a supposedly abstract art?
The insight that there is no dematerialisation - material is all.
Wordsworth, preface to lyrical ballads, the physicality of language in its 'native' state... (Rural, naturally)
'Humble and rustic life was generally chosen, because, in that condition, the essential passions of the heart find a better soil in which they can attain their maturity, are less under restraint, and speak a plainer and more emphatic language; because in that condition of life our elementary feelings coexist in a state of greater simplicity, and, consequently, may be more accurately contemplated, and more forcibly communicated; because the manners of rural life germinate from those elementary feelings, and, from the necessary character of rural occupations, are more easily comprehended, and are more durable; and, lastly, because in that condition the passions of men are incorporated with the beautiful and permanent forms of nature. The language, too, of these men has been adopted (purified indeed from what appear to be its real defects, from all lasting and rational causes of dislike or disgust) because such men hourly communicate with the best objects from which the best part of language is originally derived; and because, from their rank in society and the sameness and narrow circle of their intercourse, being less under the influence of social vanity, they convey their feelings and notions in simple and unelaborated expressions. Accordingly, such a language, arising out of repeated experience and regular feelings, is a more permanent, and a far more philosophical language, than that which is frequently substituted for it by Poets, who think that they are conferring honour upon themselves and their art, in proportion as they separate themselves from the sympathies of men, and indulge in arbitrary and capricious habits of expression, in order to furnish food for fickle tastes, and fickle appetites, of their own creation.'
Borges explained this with the example of 'the river of time' - a metaphor many of us use without ever spending time near a river.
