Perception requires original receptivity that is neither identity nor radical alterity

Evidence

Sense perception can only perceive what is other than itself; consequently, the sensible in so far as it is sensed is an alteration of that which senses. The like cannot be affected by the like; one must thus admit an originary receptivity, a passivity of the organ of sense towards that which is not itself. Yet this alterity cannot be a radical alterity. — Catherine Malabou, The Future of Hegel, 434

Categorization

• QUESTION: This ‘alterity that is not radical’ is the pivot for the plasticity frame — worth pinning down exactly what degree of otherness the passive organ tolerates and at what point it spills into disruptive excess.
• XREF: Ties directly to the reader’s MOC question about the conditions under which plastic receptivity tips into plastic explosiveness — the middle term ‘alterity that cannot be radical’ is where that tipping point must be theorized.
