Wittgenstein posits: 

''language pictures facts''

Then changes his mind 

and retracts.

''It's more complex than I

at first thought;

my tractatus has all

come to nought,

and there's more,

to them cats,

on those mats''.

 

If logic's the theory of proof 

and inference a process to truth;

then it's impossible to state,

a premise, then negate,

the conclusion-

unless it's a spoof.
