Plasticity is structural transformation operating within closure rather than beyond it

Evidence

If saturation follows from a closure of the horizon, vacancy, for its part, opens up perspectives. This contradictory unity of saturation and vacancy is exactly what appears in the very form of the Hegelian System, which integrates while it dissociates, which unifies everything while letting what comes come. Plasticity designates the future understood as future within closure, the possibility of a structural transformation: a transformation of structure within structure, a mutation ‘right at the level of the form’. — Catherine Malabou, The Future of Hegel, 1281

Categorization

• DEFINE: This is the book’s culminating definition of plasticity as the future-within-closure — the core concept the reader is tracing through to brain work.
• XREF: Directly bridges to the reader’s brain research: structural plasticity within a closed neural system, mutation at the level of form, is the core analogy she is pursuing. — connects to: A closed system’s openness to modification while transforming itself is plasticity — Catherine Malabou, The Future of Hegel: Plasticity,…, 1283; Plasticity holds origin and self-abandonment together in one capacity; Plasticity frames a challenge between giving form and exploding form — Catherine Malabou, What Should We Do with Our Brain?, 267
• DEEPTHINKING: The definition of plasticity as transformation of structure within structure — freedom that is not an escape from closure but a reshaping of it — is the conceptual keystone of the whole project and resists one-sentence summary.
• corroborated: 2 independent passages support this claim — Catherine Malabou, The Future of Hegel: Plasticity,…, 1281
