Being unable at present to write a second
paper on The Algebra of Logic I make notes for one.
Notes on Previous Paper
On Chapter I §4. I have represented that the properties
of the negative were
1st = A-overline = (A fork X)
2nd = A fork A-double-overline
3rd = A-double-overline fork A
In my circular I have shown stated correctly that 2nd= follows from
first and incorrectly that 3d=follows from 1st=, which
it don't. Very subtle fallacy [drawn?] from long
reduction of mood.
Observe 1st= is not balanced
Give table of moods etc.
