Intentionality/Geach: three-digit relation: person-verb-object. - E.g. For a z, z is a man and I saw z in Oxford under the aspect: "ran past". - GeachVsBuridan: "ratio", "appeals to", "regard": here there are no identity conditions. - There is no need for the subject to be perceived under this aspect. - E.g. Buridan: Socrates knows that some stars are above the horizon." - Geach: Suppose, Socrates is in the jungle, from which does he know?
Buridan: "of those who are it". - GeachVs: only of "some", not e.g. from the constellation Aries (false aspect). - Incorrect complex expression: "Socrates, knows that Aries over ..." - GeachVsBuridan: exploits here the peculiarity of "know". (from knowledge follows truth).
Intentional Identity/Intentionality/Geach: E.g.
