[FOM] Misattributed quotation (re: occurrences)

[A.P. Hazen]

My mistake.  The reference to the "obscure" concept of an occurrence 
I had in mind, and attributed to Charles Parsons, was the passage 
from Mates's book that Parsons has now provided.  I'm sorry.

The passage does illustrate some of the phenomena I think are 
interesting in the matter of occurrences:
(i) The occurrence notion, whatever its obscurities, is very 
convenient if you want to give a natural, idiomatic, user-friendly 
exposition of the logical niceties of variables and substitution for 
variables, but
(ii) The "standard" ontology for metamathematical discourse-- 
expression-types and numbers-- allows us IN PRINCIPLE to dispense 
with it.
