23770 | Reductive analysis makes a concept clearer, by giving an alternative simpler set [Williams,NE] |
Full Idea: A reductive analysis is one that provides an alternative set of concepts by which some target concept can be understood. It must be non-circular, and given in terms of concepts that are themselves better understood. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 01.2) | |
A reaction: There seem to be two aims of analysis: this one emphasises understanding, but the other one concerns ontology - by demonstrating that some concept or thing can be understood fully by what happens at a lower level. |
23769 | Promoting an ontology by its implied good metaphysic is an 'argument-by-display' [Williams,NE] |
Full Idea: The form of argument which sells an ontology on the basis a metaphysic is known as an 'argument-by-display'. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 01.2) | |
A reaction: [Attributed to John Bigelow 1999] New to me, but I'm quite a fan of this. For example, my rejection of platonism is not based on specific arguments, but on looking at the whole platonic picture of reality. |
10397 | Abelard's mereology involves privileged and natural divisions, and principal parts [Abelard, by King,P] |
Full Idea: Abelard's theory of substantial integral wholes is not a pure mereology in the modern sense, since he holds that there are privileged divisions; ..the division of a whole must be into its principal parts. Some wholes have a natural division. | |
From: report of Peter Abelard (works [1135]) by Peter King - Peter Abelard 2 | |
A reaction: This is a mereology that cuts nature at the joints, rather than Lewis's 'unrestricted composition', so I find Abelard rather appealing. |
23783 | Change exists, it is causal, and it needs an explanation [Williams,NE] |
Full Idea: There is a phenomenon of change. I am starting with the assumptions that it is a causal phenomenon, and that it requires explanation. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 06.1) | |
A reaction: That is, I take it, that we need a theory which explains change, rather than just describing it. Well said. Williams says, roughly, that each stage causes the next stage. |
23784 | Processes don't begin or end; they just change direction unexpectedly [Williams,NE] |
Full Idea: No process every really starts or ends. …A process we see as derailed is really just an expected sequence that continues in an unexpected direction. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 06.3) | |
A reaction: Obviously if you cannot individuate processes, then the concept of a process is not much use in ontology. Williams rejects processes, and I think he is probably right. He breaks processes down into smaller units. |
23790 | Processes are either strings of short unchanging states, or continuous and unreducible events [Williams,NE] |
Full Idea: Processes can be modelled in two ways. They are drawn out events encompassing many changes, but dissectible into short-lived states, none including change. Or they are continuous and impenetrable, and to split them is impossible. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 09.3) | |
A reaction: Obviously a process has temporal moments in it, so the unsplittability is conceptual. I find the concept of changeless parts baffling. But if processes are drawn out, they can't be basic to ontology. |
16062 | A necessary relation between fact-levels seems to be a further irreducible fact [Lynch/Glasgow] |
Full Idea: It seems unavoidable that the facts about logically necessary relations between levels of facts are themselves logically distinct further facts, irreducible to the microphysical facts. | |
From: Lynch,MP/Glasgow,JM (The Impossibility of Superdupervenience [2003], C) | |
A reaction: I'm beginning to think that rejecting every theory of reality that is proposed by carefully exposing some infinite regress hidden in it is a rather lazy way to do philosophy. Almost as bad as rejecting anything if it can't be defined. |
16061 | If some facts 'logically supervene' on some others, they just redescribe them, adding nothing [Lynch/Glasgow] |
Full Idea: Logical supervenience, restricted to individuals, seems to imply strong reduction. It is said that where the B-facts logically supervene on the A-facts, the B-facts simply re-describe what the A-facts describe, and the B-facts come along 'for free'. | |
From: Lynch,MP/Glasgow,JM (The Impossibility of Superdupervenience [2003], C) | |
A reaction: This seems to be taking 'logically' to mean 'analytically'. Presumably an entailment is logically supervenient on its premisses, and may therefore be very revealing, even if some people think such things are analytic. |
23786 | The status quo is part of what exists, and so needs metaphysical explanation [Williams,NE] |
Full Idea: The status quo is part of what exists, and thus it is a proper topic of concern for the metaphysician, and so it warrants explanation. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 07.2) | |
A reaction: His point is that ontology as a mere inventory of things gives no account of why they remain unchanged, as well as their processes and connections. |
23768 | A metaphysic is a set of wider explanations derived from a basic ontology [Williams,NE] |
Full Idea: A metaphysic is what you get when you embed a fundamental ontology within a larger metaphysical framework by repeatedly appealing to elements of that ontology in explaining metaphysical phenomena. …Only then do you see what the ontology is worth. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 01.1) | |
A reaction: Confirming my mantra that metaphysics is an explanatory activity. I think it is important that the ontology includes relations (such as 'determinations'), and is not just an inventory of types of entity. |
23773 | Humeans say properties are passive, possibility is vast, laws are descriptions, causation is weak [Williams,NE] |
Full Idea: The main components of neo-Humean metaphysics are that properties are inherently non-modal and passive, that what is possible is restricted only by imagination and coherence, that laws are non-governing descriptions, and causation is weak and extrinsic. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 02.1) | |
A reaction: This is Williams identifying the enemy, prior to offering the much more active and restictive powers ontology. I'm with Williams. |
23779 | We shouldn't posit the existence of anything we have a word for [Williams,NE] |
Full Idea: There seems to be a mysterious desire to posit entities simply because certain terms pop up in our vocabulary. But we should not be so indiscriminate about our posits, even if our talk is properly vetted. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 04.1) | |
A reaction: This should hardly need saying, and the familiar example is 'for the sake of' entailing sakes, but it seems to be a vice that is still found in metaphysical philosophy. The word 'nothingness' comes to mind. |
16060 | Nonreductive materialism says upper 'levels' depend on lower, but don't 'reduce' [Lynch/Glasgow] |
Full Idea: The root intuition behind nonreductive materialism is that reality is composed of ontologically distinct layers or levels. …The upper levels depend on the physical without reducing to it. | |
From: Lynch,MP/Glasgow,JM (The Impossibility of Superdupervenience [2003], B) | |
A reaction: A nice clear statement of a view which I take to be false. This relationship is the sort of thing that drives people fishing for an account of it to use the word 'supervenience', which just says two things seem to hang out together. Fluffy materialism. |
16064 | The hallmark of physicalism is that each causal power has a base causal power under it [Lynch/Glasgow] |
Full Idea: Jessica Wilson (1999) says what makes physicalist accounts different from emergentism etc. is that each individual causal power associated with a supervenient property is numerically identical with a causal power associated with its base property. | |
From: Lynch,MP/Glasgow,JM (The Impossibility of Superdupervenience [2003], n 11) | |
A reaction: Hence the key thought in so-called (serious, rather than self-evident) 'emergentism' is so-called 'downward causation', which I take to be an idle daydream. |
23780 | Every possible state of affairs is written into its originating powers [Williams,NE] |
Full Idea: On the model of powers I prefer, every possible state of affairs that can arise is written into the powers that would constitute them. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 04.3) | |
A reaction: I can't make any sense of 'written into', any more than I could when Leibniz proposed roughly the same thing about monads. I presume he means that any state of affairs which ever arises is the expression of the intrinsic nature of powers. |
23789 | Naming powers is unwise, because that it usually done by a single manifestation [Williams,NE] |
Full Idea: Naming powers is unwise; the main reason is that there is a long tradition of naming powers according to the manifestations they can produce, and that does not square well with multi-track powers. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 08.4) | |
A reaction: On the other hand there must be some attempt to individuate powers (by scientists, if not by philosophers), and that can only rely on the manifestations. Describe them, rather than name them? Just assign them a number! |
23775 | Powers are 'multi-track' if they can produce a variety of manifestations [Williams,NE] |
Full Idea: Powers are 'multi-track', meaning that they are capable of producing a variety of different manifestations when me with diverse stimuli. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 03.1) | |
A reaction: He later mentions magnetism. Not convinced of this. Powers probably never exist in isolation, so a different manifestation could be because a different power becomes involved. (Bird is a single-tracker). |
23771 | Fundamental physics describes everything in terms of powers [Williams,NE] |
Full Idea: Physics describes fundamental entities exclusively in terms of what sound like powers. 'Charge' names the power to produce electromagnetic fields; 'spin' the power to contribute to the angular momentum of of system; 'mass' to produce gravitational force. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 01.4) | |
A reaction: These are the three basic properties of an electron, which is fundamental in the standard model. You can say that their field is more fundamental than the particles, but the field is also only known as a set of powers. Powers rule! |
23776 | Rather than pure powers or pure categoricals, I favour basics which are both at once [Williams,NE] |
Full Idea: Power Monism: all properties are powers. Categoricalism: all fundamentals are categorical. Dualism allows both types. I defend Mixed Monism - that there is a single class of fundamental properties that are at once powerful and categorical. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 03.3) | |
A reaction: This is the main dilemma for the powers ontology - of how powers can be basic, if there needs to be some entity which possesses the power. But what possesses the powers of an electron? I like Williams's idea, without being clear about it. |
23777 | Powers are more complicated than properties which are always on display [Williams,NE] |
Full Idea: The mode in which a power presents itself is more complicated than those properties that have (strictly) nothing more to them than that which is always on display. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 03.3) | |
A reaction: This is the key idea that nature is dynamic, and so must consist of potentials as well as actuals. Interesting distinction. A basic division between those properties 'always on display', and those that are not? |
23774 | There are basic powers, which underlie dispositions, potentialities, capacities etc [Williams,NE] |
Full Idea: It is no surprise that talk of dispositions, capacities, abilities, tendencies, powers, and potentialities are part of our everyday interactions. …I have in mind a basic set of powers, the sort which underlie all of these. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 03.1) | |
A reaction: This strikes me as the correct picture. It is misleading say that a ball has a 'power' to roll smoothly. The powers are inside the ball. |
23791 | Dispositions are just useful descriptions, which are explained by underlying powers [Williams,NE] |
Full Idea: Powers are the properties at the core of the powers ontology, and dispositions are more like useful talk. …Dispositions are the phenomena to be explained by the power metaphysic. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 10.2) | |
A reaction: The picture I subscribe to. The first step is to see nature as dynamic (as Aristotle does with his 'potentialities'), and the next step to understand what must ground these dynamic dispositional properties. He calls dispositions 'process initiators'. |
10396 | If 'animal' is wholly present in Socrates and an ass, then 'animal' is rational and irrational [Abelard, by King,P] |
Full Idea: Abelard argued that if the universal 'animal' were completely present in both Socrates and an ass, making each wholly an animal, then the same thing, animal, will be simultaneously rational and irrational, with contraries present in the whole thing. | |
From: report of Peter Abelard (works [1135]) by Peter King - Peter Abelard 2 | |
A reaction: If we have universals for rationality and irrationality, they can distinguish the two. But we must also say that rationality is not an aspect of animal, which seems to mean that mind isn't either. What is the essence of an animal? Not reason? |
10395 | Abelard was an irrealist about virtually everything apart from concrete individuals [Abelard, by King,P] |
Full Idea: Abelard was an irrealist about universals, but also about propositions, events, times other than the present, natural kinds, relations, wholes, absolute space, hylomorphic composites, and the like. The concrete individual is enough to populate the world. | |
From: report of Peter Abelard (works [1135]) by Peter King - Peter Abelard 2 | |
A reaction: If a Nominalist claims that 'only particulars exist', this makes him an extreme nominalist, and remarkably materialistic for his time (though he accepted the soul, as well as God). |
15384 | Only words can be 'predicated of many'; the universality is just in its mode of signifying [Abelard, by Panaccio] |
Full Idea: Abelard concluded that only words can be 'predicated of many'. A universal is nothing but a general linguistic predicate, and its universality depends not on its mode of being, but on its mode of signifying. | |
From: report of Peter Abelard (works [1135]) by Claude Panaccio - Medieval Problem of Universals 'Peter' | |
A reaction: Abelard seems to be the originator of what is now called Predicate Nominalism, with Nelson Goodman as his modern representative. If it is just words, is there no fact of two things having the 'same' property? |
23772 | If objects are property bundles, the properties need combining powers [Williams,NE] |
Full Idea: If objects are bundles of properties …they must be robust enough to enter into building relations with one another such that they can form objects. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 01.5) | |
A reaction: A very nice point. The Humean bundle view of objects just seems to take properties to be 'impressions' or verbal predicates, but they must have causal powers to be a grounding for ontology. |
23788 | Four-Dimensional is Perdurantism (temporal parts), plus Eternalism [Williams,NE] |
Full Idea: 'Perdurantism' is the view that objects persist by being composed of temporal parts. When it is commonly combined with the eternalist account of the ontology of time, the result is known as 'four-dimensionalism'. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 08.1) | |
A reaction: At last, a clear account of the distinction between these two! They're both wrong. He says the result is the spatiotemporal 'worm' view (i.e. one temporal extended thing, rather than a collection of parts). |
8481 | The de dicto-de re modality distinction dates back to Abelard [Abelard, by Orenstein] |
Full Idea: The de dicto-de re modality distinction dates back to Abelard. | |
From: report of Peter Abelard (works [1135]) by Alex Orenstein - W.V. Quine Ch.7 | |
A reaction: Most modern philosophers couldn't (apparently) care less where a concept originated, but one of the principles of this database is that such things do matter. I'm not sure why, but if we want the whole picture, we need the historical picture. |
15385 | Abelard's problem is the purely singular aspects of things won't account for abstraction [Panaccio on Abelard] |
Full Idea: Abelard's problem is that it is not clear how singular forms could do the job they are supposed to do - to account for abstraction, namely - if they were purely singular aspects. | |
From: comment on Peter Abelard (works [1135]) by Claude Panaccio - Medieval Problem of Universals 'Peter' | |
A reaction: A very nice question! If we say that abstracta are just acquired by ignoring all but that feature in some objects, how do we identify 'that' feature in order to select it? The instances must share something in common to be abstracted. |
15383 | Nothing external can truly be predicated of an object [Abelard, by Panaccio] |
Full Idea: Abelard argued from the commonly accepted definition of a universal as 'what can be predicated of man', that no external thing can ever be predicated of anything. | |
From: report of Peter Abelard (works [1135]) by Claude Panaccio - Medieval Problem of Universals 'Peter' | |
A reaction: It sounds to me as if Abelard is confusing predicates with properties! Maybe no external can be a property of anything, but I take predicates to just be part of what you can say about anything, and that had better included external facts. |
10398 | Natural kinds are not special; they are just well-defined resemblance collections [Abelard, by King,P] |
Full Idea: In Abelard's view a natural kind is a well-defined collection of things that have the same features, so that natural kinds have no special status, being no more than discrete integral wholes whose principle of membership is similarity. | |
From: report of Peter Abelard (works [1135]) by Peter King - Peter Abelard 2 | |
A reaction: I take a natural kind to be a completely stable and invariant class of things. Presumably this invariance has an underlying explanation, but Abelard seems to take the Humean line that we cannot penetrate beyond the experienced surface. |
23782 | Causation is the exercise of powers [Williams,NE] |
Full Idea: Causation is the exercising of powers. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 06.1) | |
A reaction: Job done. Get over it. This is the view I prefer. |
23785 | Causation needs to explain stasis, as well as change [Williams,NE] |
Full Idea: I believe that it is also the job of a theory of causation to explain non-change | |
From: Neil E. Williams (The Powers Metaphysics [2019], 07.2) | |
A reaction: Good point. Most attempts to pin down causation refer only to changes and differences. Two playing cards propping one another up is his example. |
23787 | If causes and effects overlap, that makes changes impossible [Williams,NE] |
Full Idea: It would be shocking if an account of causation ruled out the possibility of change. But if a cause perfectly overlaps its effect in time, then the rejection of change is precisely what follows. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 07.6) | |
A reaction: He cites Kant, Martin, Heil and Mumford/Anjum for this view. The latter seem to see causation as a 'process' (allowing change), which Williams as ruled out. The Williams point must be correct. |
23778 | Powers contain lawlike features, pointing to possible future states [Williams,NE] |
Full Idea: Powers carry their lawlike features within them: it is part of their essence, qua power. Their pointing at future states just is their internal law-like nature; it is what gets expressed in such and such conditions. | |
From: Neil E. Williams (The Powers Metaphysics [2019], 03.3) | |
A reaction: Modern writers on powers seem unaware that Leibniz got there first. This seems to me the correct account of the ontology of laws. The formulation of laws is probably the best descriptive system for nature's patterns (over time as well as space). |
