Peircers,

On to the next part of =A73.  Application of the Algebraic Signs to Logic.

The Sign of Involution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

I shall take involution in such a sense that x^y will denote everything whi=
ch is an x for every =

individual of y.  Thus l^w will be a lover of every woman.  Then (s^l)^w wi=
ll denote whatever stands =

to every woman in the relation of servant of every lover of hers;  and s^(l=
w) will denote whatever =

is a servant of everything that is lover of a woman.  So that

=95 (s^l)^w  =3D  s^(lw).
