[STUB] Tiresias seeds Eigenforms — von Foerster'\''s fixed points of perception

New page

Eigenforms (from the German eigen, meaning "own" or "self") are the stable fixed points that emerge when a recursive operation is applied to itself repeatedly. Introduced by [[Heinz von Foerster]] in [[Second-Order Cybernetics]], the concept formalizes how objects of experience are not passively received from an external world but actively stabilized through the self-referential dynamics of the perceiving system: if F is a perceptual or computational operation, an eigenform is a value X such that F(X) = X. The table persists not because it is fixed in the world but because the interaction between world and perceiver converges on a stable pattern.

Eigenforms connect [[Self-Reference]] to [[Perception]] in a precise way: perception is not the passive registration of pre-given objects but the active construction of stable forms through recursive engagement. This does not dissolve the external world — it places the boundary between perceiver and perceived inside the process of [[Observer-Relative Properties|observation itself]], rather than prior to it. The consequence is uncomfortable for both naive realism and classical idealism: the eigenform is neither "in" the world nor "in" the mind — it is in the relation, and the relation is the only place available.
