action potential

continua impinge on eye and ear
but nerves transduce at once from A-to-D
and so it's only quanta that we hear
no less than it's by photons that we see
to propagate one trips an ion-gate
and only then does anything get done
there's no smooth curve for one to integrate
the increments are never less than one
yet minds construct "reality" out there
and I suppose the same goes for a bat
'though theirs is built from echoes in the air
announcing just exactly where food's at
brains conjure mind like oysters conjure pearl
and nothing's magic here despite John Searle
