| 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. |
| 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. |
| 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. |
| 16641 | Whiteness does not exist, but by it something can exist-as-white [Aquinas] |
| Full Idea: Whiteness is said to exist not because it subsists in itself, but because by it something has existence-as-white. | |
| From: Thomas Aquinas (Quodlibeta [1267], IX.2.2), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 10.2 | |
| A reaction: It seems unavoidable to refer to the whiteness as 'it'. It might be called the 'adverbial' theory of properties, as ways of doing something. |
| 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). |
| 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! |
| 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'. |
| 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). |
| 22170 | Senses grasp external properties, but the understanding grasps the essential natures of things [Aquinas] |
| Full Idea: Our imagination and senses grasp only the outer properties of things, not their natures. ...Understanding, however, grasps the very substance and nature of things, so that what is represented in understanding is a likeness of thing's very essence. | |
| From: Thomas Aquinas (Quodlibeta [1267], 8.2.2) | |
| A reaction: This is exactly the picture I endorse for modern science. Explanation is the path to understanding, and that must venture beyond immediate experience. |
| 22169 | Initial universal truths are present within us as potential, to be drawn out by reason [Aquinas] |
| Full Idea: For present in us by nature are certain initial truths everyone knows, in which lie potentially known conclusions our reasons can draw out and make actually known. | |
| From: Thomas Aquinas (Quodlibeta [1267], 8.2.2) | |
| A reaction: Note that these are truths rather than concepts, but that they have to be 'drawn out' by reason. This is Descartes' view of the matter, where the 'natural light' of reason is needed to articulate what is innate, such as geometry. |
| 22168 | Minds take in a likeness of things, which activates an awaiting potential [Aquinas] |
| Full Idea: What the mind takes in is not some material element of the agent, but a likeness of the agent actualising some potential the patient already has. This, for example, is the way our seeing takes in the colour of a coloured body. | |
| From: Thomas Aquinas (Quodlibeta [1267], 8.2.1) | |
| A reaction: This is exactly right. Descartes agreed. It works for colour, but not (obviously) for cheese graters. |
| 17488 | Empiricist theories are sets of laws, which give explanations and reductions [Glennan] |
| Full Idea: In the empiricist tradition theories were understood to be deductive closures of sets of laws, explanations were understood as arguments from covering laws, and reduction was understood as a deductive relationship between laws of different theories. | |
| From: Stuart Glennan (Mechanisms [2008], 'Intro') | |
| A reaction: A lovely crisp summary of the whole tradition of philosophy of science from Comte through to Hempel. Mechanism and essentialism are the new players in the game. |
| 17493 | Modern mechanism need parts with spatial, temporal and function facts, and diagrams [Glennan] |
| Full Idea: Modern champions of mechanisms say models should identify both the parts and their spatial, temporal and functional organisation, ...and the practical importance of diagrams in addition to or in place of linguistic representations of mechanisms. | |
| From: Stuart Glennan (Mechanisms [2008], 'Discover') | |
| A reaction: Apparently chemists obtain much more refined models by using mathematics than they did by diagrams or 3D models (let alone verbal descriptions). For that reason, I'm thinking that 'model' might be a better term than 'mechanism'. |
| 17487 | Mechanistic philosophy of science is an alternative to the empiricist law-based tradition [Glennan] |
| Full Idea: To a significant degree, a mechanistic philosophy of science can be seen as an alternative to an earlier logical empiricist tradition in philosophy of science that gave pride of place to laws of nature. | |
| From: Stuart Glennan (Mechanisms [2008], 'Intro') | |
| A reaction: Lovely! Someone who actually spells out what's going on here. Most philosophers are far too coy about explaining what their real game is. Mechanism is fine in chemistry and biology. How about in 'mathematical' physics, or sociology? |
| 17489 | Mechanisms are either systems of parts or sequences of activities [Glennan] |
| Full Idea: There are two sorts of mechanisms: systems consist of collections of parts that interact to produce some behaviour, and processes are sequences of activities which produce some outcome. | |
| From: Stuart Glennan (Mechanisms [2008], 'Intro') | |
| A reaction: [compressed] The second one is important because it is more generic, and under that account all kinds the features of the world that need to be explained can be subsumed. E.g. hyperinflation in an economy is a 'mechanism'. |
| 17490 | 17th century mechanists explained everything by the kinetic physical fundamentals [Glennan] |
| Full Idea: 17th century mechanists said that interactions governed by chemical, electrical or gravitational forces would have to be explicable in terms of the operation of some atomistic (or corpuscular) kinetic mechanism. | |
| From: Stuart Glennan (Mechanisms [2008], 'Intro') | |
| A reaction: Glennan says science has rejected this, so modern mechanists do not reduce mechanisms to anything in particular. |
| 17491 | Unlike the lawlike approach, mechanistic explanation can allow for exceptions [Glennan] |
| Full Idea: One of the advantages of the move from nomological to mechanistic modes of explanation is that the latter allows for explanations involving exception-ridden generalizations. | |
| From: Stuart Glennan (Mechanisms [2008], 'regular') | |
| A reaction: The lawlike approach has endless problems with 'ceteris paribus' ('all things being equal') laws, where specifying all the other 'things' seems a bit tricky. |
| 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. |
| 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. |
| 17494 | Since causal events are related by mechanisms, causation can be analysed in that way [Glennan] |
| Full Idea: Causation can be analyzed in terms of mechanisms because (except for fundamental causal interactions) causally related events will be connected by intervening mechanisms. | |
| From: Stuart Glennan (Mechanisms [2008], 'causation') | |
| A reaction: This won't give us the metaphysics of causation (which concerns the fundamentals), but this strikes me as a very coherent and interesting proposal. He mentions electron interaction as non-mechanistic causation. |
| 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). |
