Peter Geach on Predication - Dictionary of Arguments

I 52
Naming/Denotation/Two-Names Theory/GeachVsAristoteles: Incorrect approximation of predication and naming: as if predicates were (complex) names : "on the mat".
, >Predication, >Attribution, >Names, >Predicates, >Aristotle.
((s) "The man stabbing Caesar to death stabbed the one stabbed by Brutus.")
Geach: Additionally, Geach would use a link.
Two-names theory/Aristotle/Geach: "Socrates is a philosopher" should be true because the thing is named.
GeachVs: "Philosopher" (general term) is not a name for "all (or every) philosopher".
>General terms.
I 70
Contradictory predications like "Fa" and "~Fa" refer to a common subject - there are no "contradictory subjects".
>Beliefs/Geach, >Belief ascription.
I 252
Predication/Geach: can be done without naming: in an if-clause or in an or-clause, a term P can be predicated from a thing without naming the thing with "P".
E.g. "If that what the police officer has said, is true, then he was driving faster than 60". This does not name the police officer's sentence as true. - (> Conditional). - Predication/naming: century-old error: the predicate is predicated from the thing - Frege: Difference >Designation, >Denotation, >Predication: to name a thing "P", a sentence must be asserted! But a property is also predicated in a non-asserting sub-clause (subset) - therefore, naming must be explained by predication, not vice versa.
I 290
Predication/Geach: wrong: to read "SiP" as "a thing is a predicate" - (origin: "Two-Names-Theory, Aristotle) a subject cannot be negated - sentence negation: negation of the predicate.
I 291
GeachVsAristoteles: Vs "Two-Names-Theory"/TNT: confuses the relation of names to the named with relation of the predicate to what it is stated from -> false doctrine of the Trinity.
I 295
Prediction/Theology/Thomas Aquinas: the expression after "as" is predicative: e.g., "Christ inasmuch as he is human". - Distinction between subject and predicate, VsTwo-Name-Theory.
>Thomas Aquinas.
False: Two-Name-Theory: E.g.: "His godly nature is immortal, his human nature is mortal".
Aquinas: can distinguish "Christ as human is God". False: Two-name-theory: cannot do this because "human" and "God" are merely two names. >Two name theory: see above).
VsOckham: E.g. for him, "humanitas" is not more than "majesty": a disguised name for a concrete thing.
Problem: for Ockham, humanity is no longer human when viewed as the Son of God.
VsOckham: because it is not genuinely abstract, e.g. the mayor's office becomes the mayor.
>William of Ockham.
I 300
Predication/Thomas Aquinas/Geach: Subject: refers to a suppositum (an "accepted") predicate: refers to a form or nature.
Predication: unequal naming: E.g. "The Prime Minister became Prime Minister" - Nonsense: "which Prime Minister?".
