Essentialism says some of a thing's properties are necessary, and could not be absent [Cartwright,R]
|
|
Full Idea:
Essentialism, as I shall understand it, is the doctrine that among the attributes of a thing some are essential, others merely accidental. Its essential attributes are those it has necessarily, those it could not have lacked.

From:
Richard Cartwright (Some Remarks on Essentialism [1968], p.149)
|
|
A reaction:
The problem with this, which Cartwright does not address, is that trivial and gerrymandered properties (such as having self-identity, or being 'such that 2+2=4') seem to be necessarily, but don't seem to constitute the essence of a thing.

An act of ostension doesn't seem to need a 'sort' of thing, even of a very broad kind [Cartwright,R]
|
|
Full Idea:
For an ostension to be successful it is surely not necessary that I gather what sort of object it is you have indicated, such as being a horse or a zebra. I may even gather which thing you have indicated without knowing that it is a mammal or even alive.

Richard Cartwright (Some Remarks on Essentialism [1968], p.157)
|
|
A reaction:
This nicely articulates the objection I have always felt to Geach's relative identity. 'Oh my God, what the hell is THAT???' is probably going to be a successful act of verbal reference, even while explicitly denying all knowledge of sortals.

The 'doctrine of the given' is correct; some beliefs or statements are self-justifying [Chisholm]
|
|
Full Idea:
In my opinion, the 'doctrine of the given' is correct in saying that there are some beliefs or statements which are 'self-justifying' and that among such beliefs are statements some of which concern appearances or 'ways of being appeared to'.

|
From:
Roderick Chisholm (The Myth of the Given [1964], §12)
|
|
A reaction:
To boldly assert that they are 'self-justifying' invites a landslide of criticisms, pointing at a regress. It might be better to say they are self-evident, or intuitively known, or primitive, or true by the natural light of reason.
