Call 'nominalism' the denial of numbers, properties, relations and sets [Dorr]
|
|
Full Idea:
Just as there are no numbers or properties, there are no relations (like 'being heavier than' or 'betweenness'), or sets. I will provisionally use 'nominalism' for the conjunction of these four claims.

Cian Dorr (There Are No Abstract Objects [2008], 1)
|
|
A reaction:
If you are going to be a nominalist, do it properly! My starting point in metaphysics is strong sympathy with this view. Right now [Tues 22nd Nov 2011, 10:57 am GMT] I think it is correct.

'Substance theorists' take modal properties as primitive, without structure, just falling under a sortal [Paul,LA]
|
|
Full Idea:
Some deep essentialists resist the need to explain the structure under de re modal properties, taking them as primitive. One version (which we can call 'substance theory') takes them to fall under a sortal concept, with no further explanation.
|
|
From:
L.A. Paul (In Defense of Essentialism [2006], §1)
|
|
A reaction:
A very helpful identification of what Wiggins stands for, and why I disagree with him. The whole point of essences is to provide a notion that fits in with sciences, which means they must have an explanatory role, which needs structures.

If an object's sort determines its properties, we need to ask what determines its sort [Paul,LA]
|
|
Full Idea:
If the substance essentialist holds that the sort an object belongs to determines its de re modal properties (rather than the other way round), then he needs to give an (ontological, not conceptual) explanation of what determines an object's sort.
|
|
From:
L.A. Paul (In Defense of Essentialism [2006], §1)
|
|
A reaction:
See Idea 14193 for 'substance essentialism'. I find it quite incredible that anyone could think that a thing's sort could determine its properties, rather than the other way round. Even if sortals are conventional, they are not arbitrary.

Substance essentialism says an object is multiple, as falling under various different sortals [Paul,LA]
|
|
Full Idea:
The explanation of material constitution given by substance essentialism is that there are multiple objects. A person is essentially human-shaped (falling under the human sort), while their hunk of tissue is accidentally human-shaped (as tissue).
|
|
From:
L.A. Paul (In Defense of Essentialism [2006], §1)
|
|
A reaction:
At this point sortal essentialism begins to look crazy. Persons are dubious examples (with sneaky dualism involved). A bronze statue is essentially harder to dent than a clay one, because of its bronze. If you remake it of clay, it isn't the same statue.

Deep essentialist objects have intrinsic properties that fix their nature; the shallow version makes it contextual [Paul,LA]
|
|
Full Idea:
Essentialism says that objects have their properties essentially. 'Deep' essentialists take the (nontrivial) essential properties of an object to determine its nature. 'Shallow' essentialists substitute context-dependent truths for the independent ones.
|
|
From:
L.A. Paul (In Defense of Essentialism [2006], Intro)
|
|
A reaction:
If the deep essence determines a things nature, we should not need to say 'nontrivial'. This is my bete noire, the confusion of essential properties with necessary ones, where necessary properties (or predicates, at least) can indeed be trivial.

Abstracta imply non-logical brute necessities, so only nominalists can deny such things [Dorr]
|
|
Full Idea:
If there are abstract objects, there are necessary truths about these things that cannot be reduced to truths of logic. So only the nominalist, who denies that there are any such things, can adequately respect the idea that there are no brute necessities.
|
|
From:
Cian Dorr (There Are No Abstract Objects [2008], 4)
|
|
A reaction:
This is where two plates of my personal philosophy grind horribly against one another. I love nominalism, and I love natural necessities. They meet like a ring-species in evolution. I'll just call it a 'paradox', and move on (swiftly).

'Modal realists' believe in many concrete worlds, 'actualists' in just this world, 'ersatzists' in abstract other worlds [Paul,LA]
|
|
Full Idea:
A 'modal realist' believes that there are many concrete worlds, while the 'actualist' believes in only one concrete world, the actual world. The 'ersatzist' is an actualist who takes nonactual possible worlds and their contents to be abstracta.
|
|
From:
L.A. Paul (In Defense of Essentialism [2006], Intro)
|
|
A reaction:
My view is something like that modal realism is wrong, and actualism is right, and possible worlds (if they really are that useful) are convenient abstract fictions, constructed (if we have any sense) out of the real possibilities in the actual world.

The brain is not passive, and merely processing inputs; it is active, and intervenes in the world [Cobb]
|
|
Full Idea:
A number of scientists are now realising that, by viewing the brain as a computer that passively responds ot inputs and processes data, we forget that it is an active organ, part of the body intervening in the world.
|
|
From:
Matthew Cobb (The Idea of the Brain [2020], Intro)
|
|
A reaction:
I like any idea which reminds us that nature is intrinsically active, and not merely passive. Laws are in nature, not imposed on it. My preferred ontology, based on powers as fundamental, applies to the brain, as well as to physics. No free will needed.
