deliquescence

(dĕl'əkwĕs`əns), conversion of a solid substance into a liquid as a result of absorption of water vapor from the air. Since impurities in a solid lower its melting point, the absorbed water causes a decrease in the normal melting point of the solid. If enough water is absorbed to lower the melting point below room temperature, the solid will deliquesce, or turn to liquid. Lithium sulfide and magnesium iodide are examples of deliquescent salts.

Sex may be like "solitary prayer" in casting the world away, but it is also, following Mohr, a way of being opened up and in relation to pleasure, and maybe ecstasy in any, or all, its forms: "self-transcendence," "deliquescence and fusion," "engulfing embrace," "quiet peace," and "self-negation." In order to achieve these states, sex--a power larger than we--must be allowed to cast its spell on us without worldly encumbrance.

Lorsqu'on ajoute a tout cela l'absence de son qui caracterise de nombreuses sequences, on se rend compte que l'esthetique du sordide dans Une Affaire de negres rassemble de nombreux elements permettant de reveler les visages monstrueux d'un pouvoir en pleine deliquescence. Etant donne que ce documentaire est une sorte d'enquete impossible ou "foireuse," sans coupable puni, comme c'est souvent le cas en postcolonie, la prevalence de l'abjection (temporelle) pourrait, en un sens, situer le film de Lewat dans le genre du film noir, au propre et au figure, car il est bien clair que la lumiere y est un luxe.
Rendu a sa spontaneite, l'art redeviendrait alors l'expression collective du vivant primitif ; il recouvrerait sa voix primale, contaminee jusqu'alors par des apports exterieurs l'ayant soumis a leurs desseins ; il se ferait ainsi, et surtout, l'expression authentique des caracteristiques originelles de la nation qui le fait naitre, l'art indiquant, selon Celine, par son insignifiance ou sa corruption, l'etat de deliquescence de la societe et donc du peuple dont il emerge.
