Bateson and Matte-Blanco: Bio-Logic and Bi-Logic

R. Horacio Etchegoyen and Jorge L. Ahumada


Matte-Blanco's fundamental postulation of a bi-logic, with joint operation of (a) bivalent, Aristotelian or asymmetrical logic, and (b) symmetrical logic, with no distinction between part and whole, between opposites, or between self and other, is compared in this paper to Bateson's evolutionary understanding of 'mind'.

Bateson's studies of analogic and iconic mammalian communication, where 'relationship' is the 'context of context of context', add up to an emotional-relational bio-logic operating as 'action' on a part-for-whole basis. His distinction of analogic (emotional) codes dealing with continuous magnitudes, and digital codes dealing with discrete 'names', closely parallels Matte-Blanco's distinction of antinomic 'heterogenic' and 'indivisible' modes.

The understanding of the diverse 'logics' of the different levels and 'splits' of mind has much to gain from Matte-Blanco's pioneering logical approach.
