Predicate/Geach: "predicables": spurious predicates are: e.g.m, "--- smoked a pipe" - "5 is dividable by 5 and by one", as well as for "3...".
Predicate: real predicates are: e.g.,"Russell smoked a pipe" - the identity of predicates with reflexive pronouns is not assured.
I 216
Predicate/Geach: a predicate must never be confused with names. - The term does not denote the object.

Predicate/Geach: a predicate does not appear as an actual expression in the sentence.
Geach: there is no identity criterion for predicates.

Identity criterion.
One cannot know whether two predicates stand for the same property.
Equality of use is necessary condition for same reference. - ((s) That is, the extension but not the intension is equal.)

I 239
Predicate/Terminology/Geach: I call predicates only like this if they are used as the principal functor in a proposition, otherwise "predicables".
I-predicables/I-predicate/Geach/(s): those predicates in which regard the two objects are indistinguishable in a given theory.
If distinctions can be made in an extended theory, then the I-predicate does not change its meaning - E.g. "uniform" for (different but not at all differentiated) tokens of words, later the tokens are distinguished, but are still "uniform".

GeachVs two-name theory: error: that if two names denote the same thing, that they then allow the same predicates.

I 301
Predicate/Geach: Predicates such as "become" can only be assigned to concrete terms.
