In La libertad de la impermanencia, Diana Fonseca reworks volumes of Filosofía Marxista into sculpture, keeping the sober black bindings and authoritative typography of the originals while altering their physical presence through dozens of black bookmarks that emerge from between the pages. Artsy lists the work as a sculpture made from intervened books, produced in an edition of three. A bookmark ordinarily singles out a passage worth returning to. Here the sheer number of them overwhelms that function: when nearly every page is marked, the distinction between one idea and the next collapses, and the book, usually an orderly container of knowledge, becomes saturated with competing points of emphasis.

That excess is the work's argument. As Fonseca points out, a book of Marxist philosophy in Cuba was not read so much as administered, doctrine to be repeated, marked, and accentuated until the same ideology, restated past the point of meaning, empties out and turns insubstantial. The bookmarks enact exactly this. They record the exhaustive scrutiny such texts received inside a system where Marxist-Leninist thought held institutional authority, the compulsion to identify and preserve every idea within a doctrine that presented itself as complete. And they physically exceed their books, spilling outward in dense clusters that break the controlled geometry of the black volumes. What was meant to stay between the covers no longer can. 

The restraint of the exterior sits against this eruption from within, order against the movement it cannot contain.

The title sharpens the point. Fonseca sets an ideology built on historical certainty against the fact of impermanence, and rather than destroying the object she hollows it: the books remain intact and legible, their titles undisturbed, but their authority has been unsettled from inside. Each bookmark marks another possible entry, another reading, another passage a later generation might return to and revise. Certainty becomes multiplicity. The work is finally less about one ideology's decline than about the impulse to build permanent structures of thought in a world that keeps rewriting them, and it locates freedom not in arriving at a final truth but in accepting that ideas stay open to rereading and change.
