If we don't assume that events exist, we cannot make sense of our common talk [Davidson]
|
|
Full Idea:
The assumption, ontological and metaphysical, that there are events, is one without which we cannot make sense of much of our most common talk.
|
|
From:
Donald Davidson (Causal Relations [1967], §4)
|
|
A reaction:
He considers events to be unanalysable basics. Explanation of normal talk also needs ghosts, premonitions, telepathy and Father Christmas. It is extremely hard to individuate events, unless they are subatomic, and rather numerous.

Distinguish causation, which is in the world, from explanations, which depend on descriptions [Davidson, by Schaffer,J]
|
|
Full Idea:
Davidson distinguishes between causation, an extensional relation that holds between coarse events, and explanation, which is an intensional relation that holds between the coarse events under a description.
|
|
From:
report of Donald Davidson (Causal Relations [1967]) by Jonathan Schaffer - The Metaphysics of Causation 1.2
|
|
A reaction:
I'm unclear why everything has to be so coarse, when reality and causal events seem to fine-grained, but the distinction strikes me as good. Explanations relate to human understanding and human interests. Cf. Anscombe's view.

Full descriptions can demonstrate sufficiency of cause, but not necessity [Davidson]
|
|
Full Idea:
The fuller we make the description of a cause, the better our chances of demonstrating that it was sufficient (as described) to produce the effect, and the worse our chances of demonstrating that it was necessary. (For the effect, it is the opposite).
|
|
From:
Donald Davidson (Causal Relations [1967], §3)
|
|
A reaction:
If the fullness of description is relevant, this suggests that Davidson is focusing on human explanations, rather than on the ontology of causation. If the cause IS necessary, why wouldn't a better description make that clearer?

Least action is not a causal law, but a 'global law', describing a global essence [Ellis]
|
|
Full Idea:
The principle of least action is not a causal law, but is what I call a 'global law', which describes the essence of the global kind, which every object in the universe necessarily instantiates.
|
|
From:
Brian Ellis (Katzav on limitations of dispositions [2005])
|
|
A reaction:
As a fan of essentialism I find this persuasive. If I inherit part of my essence from being a mammal, I inherit other parts of my essence from being an object, and all objects would share that essence, so it would look like a 'law' for all objects.

A species requires a genus, and its essence includes the essence of the genus [Ellis]
|
|
Full Idea:
A specific universal can exist only if the generic universal of which it is a species exists, but generic universals don't depend on species; …the essence of any genus is included in its species, but not conversely.
|
|
From:
Brian Ellis (Katzav on limitations of dispositions [2005], 91)
|
|
A reaction:
Thus the species 'electron' would be part of the genus 'lepton', or 'human' part of 'mammal'. The point of all this is to show how individual items connect up with the rest of the universe, giving rise to universal laws, such as Least Action.

A hierarchy of natural kinds is elaborate ontology, but needed to explain natural laws [Ellis]
|
|
Full Idea:
The hierarchy of natural kinds proposed by essentialism may be more elaborate than is strictly required for purposes of ontology, but it is necessary to explain the necessity of the laws of nature, and the universal applicability of global principles.
|
|
From:
Brian Ellis (Katzav on limitations of dispositions [2005], 91)
|
|
A reaction:
I am all in favour of elaborating ontology in the name of best explanation. There seem, though, to be some remaining ontological questions at the point where the explanations of essentialism run out.

Without general principles, we couldn't predict the behaviour of dispositional properties [Ellis]
|
|
Full Idea:
It is objected to dispositionalism that without the principle of least action, or some general principle of equal power, the specific dispositional properties of things could tell us very little about how these things would be disposed to behave.
|
|
From:
Brian Ellis (Katzav on limitations of dispositions [2005], 90)
|
|
A reaction:
Ellis attempts to meet this criticism, by placing dispositional properties within a hierarchy of broader properties. There remains a nagging doubt about how essentialism can account for space, time, order, and the existence of essences.
