7. Existence / A. Nature of Existence / 6. Criterion for Existence
Chrysippus says action is the criterion for existence, which must be physical [Chrysippus, by Tieleman]
     Full Idea: Chrysippus regarded power to act and be acted upon as the criterion for existence or being - a test satisfied by bodies alone.
     From: report of Chrysippus (fragments/reports [c.240 BCE]) by Teun L. Tieleman - Chrysippus
     A reaction: This defines existence in terms of causation. Is he ruling out a priori a particle (say) which exists, but never interacts with anything? If so, he is inclining towards anti-realism.
7. Existence / C. Structure of Existence / 1. Grounding / a. Nature of grounding
Avoid 'in virtue of' for grounding, since it might imply a reflexive relation such as identity [Audi,P]
     Full Idea: We should not use 'in virtue of' where it might express a reflexive relation, such as identity. Since grounding is a relation of determination, and closely linked to the concept of explanation, it is irreflexive and asymmetric.
     From: Paul Audi (Clarification and Defense of Grounding [2012], 3.2)
     A reaction: E.g. he says someone isn't a bachelor in virtue of being an unmarried man, since a bachelor just is an unmarried man. I can't disagree. 'Determination' looks like the magic word, even if we don't know how it cashes out.
Ground relations depend on the properties [Audi,P]
     Full Idea: On my view, grounding relations depend on the natures of the properties involved in them.
     From: Paul Audi (Clarification and Defense of Grounding [2012], 3.2)
     A reaction: I'm cautious about this if we don't find out more exactly what properties are (and they had better not just be predicates). Maybe properties are the only apparatus we have here, though I prefer 'powers' for the fundamentals.
A ball's being spherical non-causally determines its power to roll [Audi,P]
     Full Idea: The fact that a given thing is spherical non-causally determines the fact that it has the power to roll.
     From: Paul Audi (Clarification and Defense of Grounding [2012], 3.3)
     A reaction: Quine won't accept this, because you have added something called a 'power' to the ball (intrinsically, it seems), over and above its observable sphericity. Does being a ball 'determine' that it can't be in two places at once? Order of explanation?
Ground is irreflexive, asymmetric, transitive, non-monotonic etc. [Audi,P]
     Full Idea: The logical principles about grounding include irreflexivity, asymmetry, transitivity, non-monotonicity, and so forth.
     From: Paul Audi (Clarification and Defense of Grounding [2012], 3.8)
     A reaction: [It can't ground itself, there is no mutual grounding, grounds of grounds ground, and grounding judgements are not fixed]
The best critique of grounding says it is actually either identity or elimination [Audi,P]
     Full Idea: I think the most promising skeptical strategy is to insist on either identity or elimination wherever grounding is alleged to hold.
     From: Paul Audi (Clarification and Defense of Grounding [2012], 3.9)
     A reaction: This comes after an assessment of the critiques of grounding by Oliver, Hofweber and Daly. So we don't say chemistry grounds biology, we either say biology is chemistry, or that there is no biology. Everything is just simples. Not for me.
7. Existence / C. Structure of Existence / 1. Grounding / b. Relata of grounding
Grounding is a singular relation between worldly facts [Audi,P]
     Full Idea: On my view, grounding is a singular relation between facts. ...Facts, on this view, are obtaining states of affairs.
     From: Paul Audi (Clarification and Defense of Grounding [2012], 3.2)
     A reaction: He rest this claim on his 'worldly' view of facts, Idea 17293. I seem to be agreeing with him. Note that it is not between types of fact, even if there are such general truths, such as in chemistry.
If grounding relates facts, properties must be included, as well as objects [Audi,P]
     Full Idea: Taking facts to be the relata of grounding has the interesting consequence that it does not relate ordinary particulars, objects, considered apart from their properties.
     From: Paul Audi (Clarification and Defense of Grounding [2012], 3.4)
     A reaction: It will depend on what you mean by properties, and it seems to me that something like 'powers' must be invoked, to get the active character that seems to be involved in grounding.
7. Existence / C. Structure of Existence / 1. Grounding / c. Grounding and explanation
We must accept grounding, for our important explanations [Audi,P]
     Full Idea: The reason we must countenance grounding is that it is indispensible to certain important explanations.
     From: Paul Audi (Clarification and Defense of Grounding [2012], 3.3)
     A reaction: I like this a lot. The first given of all philosophy is the drive to exlain. However, we mustn't go inventing features of the world, simply to give us the possibility of explaining it. The objective fact seems to be the without-which-not relation.
7. Existence / C. Structure of Existence / 1. Grounding / d. Grounding and reduction
Reduction is just identity, so the two things are the same fact, so reduction isn't grounding [Audi,P]
     Full Idea: I deny that when p grounds q, q thereby reduces to p, and I deny that if q reduces to p, then p grounds q. ...On my view, reduction is nothing other than identity, so p is the same fact as q.
     From: Paul Audi (Clarification and Defense of Grounding [2012], 3.5)
     A reaction: Very good. I can't disagree with any of it, and it is crystal clear. Philosophical heaven.
7. Existence / C. Structure of Existence / 2. Reduction
Multiple realisability is said to make reduction impossible [Okasha]
     Full Idea: Philosophers have often invoked multiple realisability to explain why psychology cannot be reduced to physics or chemistry, but in principle the explanation works for any higher-level science.
     From: Samir Okasha (Philosophy of Science: Very Short Intro (2nd ed) [2016], 3)
     A reaction: He gives the example of a 'cell' in biology, which can be implemented in all sorts of ways. Presumably that can be reduced to many sorts of physics, but not just to one sort. The high level contains patterns that vanish at the low level.
7. Existence / D. Theories of Reality / 8. Facts / b. Types of fact
There are simple and complex facts; the latter depend on further facts [Chrysippus, by Cicero]
     Full Idea: Chrysippus says there are two classes of facts, simple and complex. An instance of a simple fact is 'Socrates will die at a given date', ...but 'Milo will wrestle at Olympia' is a complex statement, because there can be no wrestling without an opponent.
     From: report of Chrysippus (fragments/reports [c.240 BCE]) by M. Tullius Cicero - On Fate ('De fato') 13.30
     A reaction: We might say that there are atomic and complex facts, but our atomic facts tend to be much simpler, usually just saying some object has some property.
Worldly facts are obtaining states of affairs, with constituents; conceptual facts also depend on concepts [Audi,P]
     Full Idea: The 'worldly' view of facts says they are obtaining states of affairs, individuated by their constituents and their combination. On the 'conceptual' view, facts will differ if they pick out an object or property via different concepts.
     From: Paul Audi (Clarification and Defense of Grounding [2012], 3.2)
     A reaction: Might it be that conceptual differences between facts are supervenient on worldly differences (with the worldly facts in charge)?
7. Existence / E. Categories / 3. Proposed Categories
Stoics categories are Substrate, Quality, Disposition, and Relation [Chrysippus, by Pasnau]
     Full Idea: The Stoics proposed a rather modest categorisation of Substrate, Quality, Disposition, and Relation.
     From: report of Chrysippus (fragments/reports [c.240 BCE]) by Robert Pasnau - Metaphysical Themes 1274-1671 12.1
