musing sheffer stroke and its dual thinking of nicod:


(())(())

* = intersection = (()) v ))((
u = union = ()() v )()( v )(() v ())(
a = ( v ((((
b = ) v ))))
-a = (( v (( (( (( ((
I = ( (( ( ((
0 = ( ( (( ((
* & 0 reduce equally; u & I reduce equally; a & b reduce equally;
a & -a reduce equally. think of neutrality, aphanisis, substance;
think of defuge.
pattern i = (a, -a, 0, I); pattern ii = (a, b, u, *)
the absolute ground: (())(())
( (( v ) )) = implication/non-implication, tautology/contradiction
"Since nothing in the environment corresponds to negation, negation as
well as all other 'logical particles' (inclusion, alternation,
implication, etc.) must arise within the organism as a consequence of
perceiving the relation of itself with respect to the environment."
(Heinz von Foerster, Thoughts and Notes on Cognition)
Neither, neitherness, exclusionary union, tend elsewhere, Spencer Brown
notwithstanding - but then elsewhere implies the presence of border,
maintenance, inscription in the first place.
(Culled from Structure of Reality, 1977.)
