[FOM] Concerning Ancestral Logic (CORRECTION)

[Richard Heck]

Silly omission in my previous note, one people could probably see and
fix themselves, but....

=====

Given a formula \phi, *xy(\phi(x,y))(a,b) is a formula, where x and y
are variables and a and b are terms. It is true iff there is a finite
sequence x_1, ..., x_n such that \phi(x_i,x_{i+1}) AND a=x_1 AND b=x_n.

Etc.
