17302 | 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] |
17292 | 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. |
17295 | 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. |
17297 | 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? |
17303 | 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. |
17294 | 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. |
17300 | 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. |
17296 | 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. |
17301 | 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. |
17293 | 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)? |
8845 | An experience's having propositional content doesn't make it a belief [Pryor] |
Full Idea: To say that experiences have propositional content is not to say that experiences are beliefs. | |
From: James Pryor (There is immediate Justification [2005], §4) | |
A reaction: This is important for opponents of foundationalism, because they will not allow a raw experience to act as a justification on its own. Even if concepts, or even propositions, are offered by experience, the crucial evaluation must preceded knowledge. |
8842 | The best argument for immediate justification is not the Regress Argument, but considering examples [Pryor] |
Full Idea: The best argument for immediate justification is not the Regress Argument, but from considering examples, such as I have a headache, I am raising my arm, I am imagining my grandmother, or seeing how dominoes could fill a chessboard. | |
From: James Pryor (There is immediate Justification [2005], §3) | |
A reaction: Most of his examples depend on the fact that they cannot be challenged by anyone else, because they are within his own mind. The dominoes require complex thought. The first two could be erroneous if he was dreaming. |
8843 | Impure coherentists accept that perceptions can justify, unlike pure coherentists [Pryor] |
Full Idea: Pure coherentists claim that a belief can only be justified by its relations to other beliefs; impure coherentists are willing to give some non-beliefs, such as perceptual experiences, a justifying role. | |
From: James Pryor (There is immediate Justification [2005], §4) | |
A reaction: I think I would vote for the pure version. The distinction that is needed, I think, is between justification and evidence. You have to surmise causal links and explanations before you can see an experience as evidence, and then justification. |
8844 | Coherentism rests on the claim that justifications must be beliefs, with propositional content [Pryor] |
Full Idea: The Master Argument for coherentism is the claim that a justifier requires asserted propositional content, and that only beliefs represent propositions assertively. | |
From: James Pryor (There is immediate Justification [2005], §4) | |
A reaction: I think this claim (which Pryor attacks) is correct. A key point is that almost any experience can be delusional, and in need of critical evaluation. We would even only accept an experience as being necessarily veridical after critical evaluation. |
8846 | Reasons for beliefs can be cited to others, unlike a raw headache experience [Pryor] |
Full Idea: If you have reasons for your belief, they should be considerations you could in principle cite, or give, to someone who doubted or challenged the belief. You can't give some else a non-propositional state like a headache. | |
From: James Pryor (There is immediate Justification [2005], §6) | |
A reaction: On the whole I agree, but if someone asked you to justify your claim that there is a beautiful sunset over the harbour, you could just say 'Look!'. Headaches are too private. The person must still see that the sunset is red, and not the window. |
8847 | Beliefs are not chosen, but you can seek ways to influence your belief [Pryor] |
Full Idea: Ordinarily we make no intentional choices about what to believe, but one can choose to believe something, and then seek ways to get oneself to believe it. | |
From: James Pryor (There is immediate Justification [2005], §7) | |
A reaction: Deliberately reading the articles of a philosopher that you seem to agree with would be an example. Presumably the belief that this is a good belief and should be given support is not itself voluntarily chosen. Ultimately we are helpless. See Idea 1854. |
17298 | Two things being identical (like water and H2O) is not an explanation [Audi,P] |
Full Idea: If there is identity between water and H2O, we have neither the asymmetry nor the irreflexivity that explanations require. | |
From: Paul Audi (Clarification and Defense of Grounding [2012], 3.3) | |
A reaction: Once you realise it is H2O, you understand its deeper features, which will open up new explanations. He's right, though. |
17299 | There are plenty of examples of non-causal explanation [Audi,P] |
Full Idea: There are a number of explanations where it seems clear that causation is not involved at all: normative grounded in non-normative, disposition grounded in categorical, aesthetic grounded in non-aesthetic, semantic in social and psychological. | |
From: Paul Audi (Clarification and Defense of Grounding [2012], 3.3) | |
A reaction: Apart from dispositions, perhaps, these all seem to be experienced phenomena grounded in the physical world. 'Determination' is the preferred term for non-causal grounding. |
13304 | Learned men gain more in one day than others do in a lifetime [Posidonius] |
Full Idea: In a single day there lies open to men of learning more than there ever does to the unenlightened in the longest of lifetimes. | |
From: Posidonius (fragments/reports [c.95 BCE]), quoted by Seneca the Younger - Letters from a Stoic 078 | |
A reaction: These remarks endorsing the infinite superiority of the educated to the uneducated seem to have been popular in late antiquity. It tends to be the religions which discourage great learning, especially in their emphasis on a single book. |
20820 | Time is an interval of motion, or the measure of speed [Posidonius, by Stobaeus] |
Full Idea: Posidonius defined time thus: it is an interval of motion, or the measure of speed and slowness. | |
From: report of Posidonius (fragments/reports [c.95 BCE]) by John Stobaeus - Anthology 1.08.42 | |
A reaction: Hm. Can we define motion or speed without alluding to time? Looks like we have to define them as a conjoined pair, which means we cannot fully understand either of them. |
