7 ideas

7. Existence / C. Structure of Existence / 1. Grounding / a. Nature of grounding

17304	As causation links across time, grounding links the world across levels [Schaffer,J]
	Full Idea: Grounding is something like metaphysical causation. Just as causation links the world across time, grounding links the world across levels. Grounding connects the more fundamental to the less fundamental, and thereby backs a certain form of explanation.
	From: Jonathan Schaffer (Grounding, Transitivity and Contrastivity [2012], Intro)
	A reaction: Obviously you need 'levels' for this, which we should take to be structural levels.

17306	If ground is transitive and irreflexive, it has a strict partial ordering, giving structure [Schaffer,J]
	Full Idea: By treating grounding as transitive (and irreflexive), one generates a strict partial ordering that induces metaphysical structure.
	From: Jonathan Schaffer (Grounding, Transitivity and Contrastivity [2012], Intro)
	A reaction: Schaffer's paper goes on to attach the claim that grounding is transitive, but I didn't find his examples very convincing.

7. Existence / D. Theories of Reality / 2. Realism

15049	Metaphysical realists are committed to all unambiguous statements being true or not true [Dummett]
	Full Idea: The anti-realist view undercuts the ground for accepting bivalence. ...Acceptance of bivalence should not be taken as a sufficient condition for realism. ..They accept the weaker principle that unambiguous statements are determinately true or not true.
	From: Michael Dummett (Realism and Anti-Realism [1992], p.467)
	A reaction: [cited by Kit Fine, when discussing anti-realism] I take it be quite an important component of realism that there might be facts which will never be expressed, or are even beyond our capacity to grasp or express them

14. Science / D. Explanation / 2. Types of Explanation / b. Contrastive explanations

17308	Explaining 'Adam ate the apple' depends on emphasis, and thus implies a contrast [Schaffer,J]
	Full Idea: Explaining why ADAM ate the apple is a different matter from explaining why he ATE the apple, and from why he ate THE APPLE. ...In my view the best explanations incorporate ....contrastive information.
	From: Jonathan Schaffer (Grounding, Transitivity and Contrastivity [2012], 4.3.1)
	A reaction: But why are the contrasts Eve, or throwing it, or a pear? It occurs to me that this is wrong! The contrast is with anything else which could have gone in subject, verb or object position. It is a matter of categories, not of contrasts.

18. Thought / D. Concepts / 2. Origin of Concepts / a. Origin of concepts

17722	The concept 'red' is tied to what actually individuates red things [Peacocke]
	Full Idea: The possession conditions for the concept 'red' of the colour red are tied to those very conditions which individuate the colour red.
	From: Christopher Peacocke (Explaining the A Priori [2000], p.267), quoted by Carrie Jenkins - Grounding Concepts 2.5
	A reaction: Jenkins reports that he therefore argues that we can learn something about the word 'red' from thinking about the concept 'red', which is his new theory of the a priori. I find 'possession conditions' and 'individuation' to be very woolly concepts.

26. Natural Theory / A. Speculations on Nature / 1. Nature

17305	I take what is fundamental to be the whole spatiotemporal manifold and its fields [Schaffer,J]
	Full Idea: I myself would prefer to speak of what is fundamental in terms of the whole spatiotemporal manifold and the fields that permeate it, with parts counting as derivative of the whole.
	From: Jonathan Schaffer (Grounding, Transitivity and Contrastivity [2012], 4.1.1)
	A reaction: Not quite the Parmenidean One, since it has parts, but a nice try at updating the great man. Note the reference to 'fields', suggesting that this view is grounded in the physics rather than metaphysics. How many fields has it got?

26. Natural Theory / C. Causation / 1. Causation

17307	Nowadays causation is usually understood in terms of equations and variable ranges [Schaffer,J]
	Full Idea: The leading treatments of causation work within 'structural equation models', with events represented via variables each of which is allotted a range of permitted values, which constitute a 'contrast space'.
	From: Jonathan Schaffer (Grounding, Transitivity and Contrastivity [2012], 4.3.1)
	A reaction: Like Woodward's idea that causation is a graph, this seems to be a matter of plotting or formalising correlations between activities, which is a very Humean approach to causation.
