The mind-brain relation is one of self-contradiction, not calm succession.

Evidence

Thought is therefore nothing but nature, but a negated nature, marked by its own difference from itself. The world is not the calm prolonging of the biological. The mental is not the wise appendix of the neuronal. And the brain is not the natural ideal of globalized economic, political, and social organization; it is the locus of an organic tension that is the basis of our history and our critical activity. — Catherine Malabou, What Should We Do with Our Brain?, 263

Categorization

• DEFINE: Provides the crisp statement that the brain is loci of ‘organic tension,’ grounding the plasticity/resistance reading versus docile flexibility.
• XREF: Directly echoes the reader’s core throughline that plasticity also means the power to destroy form — here as nature contradicting itself into history.
• DEEPTHINKING: The claim that thought is ‘negated nature, marked by its own difference from itself’ is dense enough to sit with: it fuses the plasticity-as-form-giving and plasticity-as-form-exploding theses into one dialectical movement.
