We could not uphold a truthmaker for 'Fa' without structures [Lewis]
|
|
Full Idea:
We could not, without structures, uphold the principle that every truth has a truthmaker. If Fa is true, the truthmaker is not F, not a, nor both together; not their mereological sum; not a set-theoretic construction. These would exist just the same.

From:
David Lewis (Comment on Armstrong and Forrest [1986], p.109)
|
|
A reaction:
This point ought to trouble Lewis, as well as Armstrong and Forrest. If we assert 'Fa', we must (in any theory) have some idea of what unites them, as well as of their separate existence. It must a fact about 'a', not a fact about 'F'.

Maybe our persistence conditions concern bodies, rather than persons [Olson, by Hawley]
|
|
Full Idea:
Instead of attributing person-like persistence conditions to bodies, we could attribute body-like persistence conditions to persons, …so human persons are identical with human organisms.
|
|
From:
report of Eric T. Olson (The Human Animal [1997]) by Katherine Hawley - How Things Persist 5.10
|
|
A reaction:
In the case of pre-birth and advanced senility, Olson thinks we could have the body without the person, so person is a 'phase sortal' of bodies. A good theory, which seems to answer a lot of questions. 'Person' may be an abstraction.

For 'animalism', I exist before I became a person, and can continue after it, so I am not a person [Olson, by Lowe]
|
|
Full Idea:
According to 'animalism', I existed before I was a person and I may well go one existing for some time after I cease to be a person; hence, I am not essentially a person, but a human organism.
|
|
From:
report of Eric T. Olson (The Human Animal [1997]) by E.J. Lowe - Introduction to the Philosophy of Mind Ch.10
|
|
A reaction:
There is a very real sense in which an extremely senile person has 'ceased to exist' (e.g. as the person I used to love). On the whole, though, I think that Olson is right, and yet 'person' is an important concept. Neither concept is all-or-nothing.
