Explanatory proofs rest on 'characterizing properties' of entities or structure [Steiner,M]
|
|
Full Idea:
My proposal is that an explanatory proof makes reference to the 'characterizing property' of an entity or structure mentioned in the theorem, where the proof depends on the property. If we substitute a different object, the theory collapses.

From:
Mark Steiner (Mathematical Explanation [1978], p.34)
|
|
A reaction:
He prefers 'characterizing property' to 'essence', because he is not talking about necessary properties, since all properties are necessary in mathematics. He is, in fact, reverting to the older notion of an essence, as the core power of the thing.

Science has shown that causal relations are just transfers of energy or momentum [Fair, by Sosa/Tooley]
|
|
Full Idea:
Basic causal relations can, as a consequence of our scientific knowledge, be identified with certain physicalistic [sic] relations between objects that can be characterized in terms of transference of either energy or momentum between objects.

report of David Fair (Causation and the Flow of Energy [1979]) by E Sosa / M Tooley - Introduction to 'Causation' §1
|
|
A reaction:
Presumably a transfer of momentum is a transfer of energy. If only anyone had the foggiest idea what energy actually is, we'd be doing well. What is energy made of? 'No identity without substance', I say. I like Fair's idea.

Fair shifted his view to talk of counterfactuals about energy flow [Fair, by Schaffer,J]
|
|
Full Idea:
Fair, who originated the energy flow view of causation, moved to a view that understands connection in terms of counterfactuals about energy flow.
|
|
From:
report of David Fair (Causation and the Flow of Energy [1979]) by Jonathan Schaffer - The Metaphysics of Causation 2.1.2
|
|
A reaction:
David Fair was a pupil of David Lewis, the king of the counterfactual view. To me that sounds like a disappointing move, but it is hard to think that a mere flow of energy through space would amount to causation. Cause must work back from an effect.
