| 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. |
| 15375 | If terms change their designations in different states, they are functions from states to objects [Fitting] |
| Full Idea: The common feature of every designating term is that designation may change from state to state - thus it can be formalized by a function from states to objects. | |
| From: Melvin Fitting (Intensional Logic [2007], 3) | |
| A reaction: Specifying the objects sounds OK, but specifying states sounds rather tough. |
| 15376 | Intensional logic adds a second type of quantification, over intensional objects, or individual concepts [Fitting] |
| Full Idea: To first order modal logic (with quantification over objects) we can add a second kind of quantification, over intensions. An intensional object, or individual concept, will be modelled by a function from states to objects. | |
| From: Melvin Fitting (Intensional Logic [2007], 3.3) |
| 15378 | Awareness logic adds the restriction of an awareness function to epistemic logic [Fitting] |
| Full Idea: Awareness logic enriched Hintikka's epistemic models with an awareness function, mapping each state to the set of formulas we are aware of at that state. This reflects some bound on the resources we can bring to bear. | |
| From: Melvin Fitting (Intensional Logic [2007], 3.6.1) | |
| A reaction: [He cites Fagin and Halpern 1988 for this] |
| 15379 | Justication logics make explicit the reasons for mathematical truth in proofs [Fitting] |
| Full Idea: In justification logics, the logics of knowledge are extended by making reasons explicit. A logic of proof terms was created, with a semantics. In this, mathematical truths are known for explicit reasons, and these provide a measure of complexity. | |
| From: Melvin Fitting (Intensional Logic [2007], 3.6.1) |
| 11026 | Classical logic is deliberately extensional, in order to model mathematics [Fitting] |
| Full Idea: Mathematics is typically extensional throughout (we write 3+2=2+3 despite the two terms having different meanings). ..Classical first-order logic is extensional by design since it primarily evolved to model the reasoning of mathematics. | |
| From: Melvin Fitting (Intensional Logic [2007], §1) |
| 11028 | λ-abstraction disambiguates the scope of modal operators [Fitting] |
| Full Idea: λ-abstraction can be used to abstract and disambiguate a predicate. De re is [λx◊P(x)](f) - f has the possible-P property - and de dicto is ◊[λxP(x)](f) - possibly f has the P-property. Also applies to □. | |
| From: Melvin Fitting (Intensional Logic [2007], §3.3) | |
| A reaction: Compare the Barcan formula. Originated with Church in the 1930s, and Carnap 1947, but revived by Stalnaker and Thomason 1968. Because it refers to the predicate, it has a role in intensional versions of logic, especially modal logic. |
| 22076 | Being is only perceptible to itself as becoming [Schelling] |
| Full Idea: Being is only perceptible to itself in the state of becoming. | |
| From: Friedrich Schelling (Of Human Freedom [1809], p.403), quoted by Jean-François Courtine - Schelling p.90 | |
| A reaction: Is the Enlightenment the era of Being, and the Romantic era that of Becoming? They like process, fluidity, even chaos. |
| 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. |
| 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). |
| 15377 | Definite descriptions pick out different objects in different possible worlds [Fitting] |
| Full Idea: Definite descriptions pick out different objects in different possible worlds quite naturally. | |
| From: Melvin Fitting (Intensional Logic [2007], 3.4) | |
| A reaction: A definite description can pick out the same object in another possible world, or a very similar one, or an object which has almost nothing in common with the others. |
| 22072 | Schelling always affirmed the absolute status of freedom [Schelling, by Courtine] |
| Full Idea: Throughout Schelling's work we find the affirmation of absolute freedom or of the absolute as freedom. | |
| From: report of Friedrich Schelling (Philosophy of Revelation [1843], Vol.13 p.359) by Jean-François Courtine - Schelling p.83 | |
| A reaction: Of all of the German idealists, Schelling may be the closest to modern existentialism. |
| 21925 | For Schelling the Absolute spirit manifests as nature in which self-consciousness evolves [Schelling, by Lewis,PB] |
| Full Idea: (Like Schopenhauer) Schelling understood the Absolute - spirit rather than will - to manifest itself as nature in which man evolves with self-consciousness. | |
| From: report of Friedrich Schelling (Outline of a System of the Philosophy of Nature [1799]) by Peter B. Lewis - Schopenhauer 4 | |
| A reaction: The influence of Spinoza seems strong here. Is his Absolute just Spinoza's 'God'? |
| 22045 | Metaphysics aims at the Absolute, which goes beyond subjective and objective viewpoints [Schelling, by Pinkard] |
| Full Idea: Schelling never lost his youthful conviction that any metaphysics had to be an explication of the 'absolute' as something that went beyond both subjective and objective points of view. | |
| From: report of Friedrich Schelling (Outline of a System of the Philosophy of Nature [1799]) by Terry Pinkard - German Philosophy 1760-1860 12 | |
| A reaction: Even for a scientific and analytic modern philosopher there must be a target of an ideal account that includes human subjectivity within an objective view of the world. Even Mysterians like McGinn would like that. |
| 22074 | We must show that the whole of nature, because it is effective, is grounded in freedom [Schelling] |
| Full Idea: What is required is to show that everything that is effective (nature, the world of things) is grounded in activity, life, freedom. | |
| From: Friedrich Schelling (Of Human Freedom [1809], p.351), quoted by Jean-François Courtine - Schelling | |
| A reaction: I take the ancestor of this view of nature to be the monads of Leibniz, as the active principle in nature. Because this is an idealist view, it starts with the absolute freedom of the Self, and presumably sees nature in its own image. |
| 22073 | The basis of philosophy is the Self prior to experience, where it is the essence of freedom [Schelling] |
| Full Idea: The highest principle of all philosophy is the Self insofar as it is purely and simply Self, not yet conditioned by an object, but where it is formulated by freedom. The alpha and omega of all philosophy is freedom. | |
| From: Friedrich Schelling (Letters to Hegel [1795], 1795 02 04), quoted by Jean-François Courtine - Schelling p.83 | |
| A reaction: A common later response to this (e.g. in Schopenhauer) is that there is no concept of the Self prior to experience. The idealists seem to adore free will, while offering no reply to Spinoza on the matter, with whom they were very familiar. |
| 22075 | Only idealism has given us the genuine concept of freedom [Schelling] |
| Full Idea: Until the discovery of idealism, the genuine concept of freedom has been missing from every modern system, whether it be that of Leibniz or of Spinoza. | |
| From: Friedrich Schelling (Of Human Freedom [1809], p.345), quoted by Jean-François Courtine - Schelling p.87 | |
| A reaction: Spinoza denied free will, and Leibniz fudged it. Evidently more medieval theological accounts were not good enough. I presume Fichte is Schelling's hero, and he seems to see freedom as axiomatic about the Self. |
| 20956 | Ultimately, all being is willing. The nature of primal being is the same as the nature of willing [Schelling] |
| Full Idea: In the last and highest instance there is no other being but willing. Willing is primal being, and all the predicates of primal being only fit willing: groundlessness, eternity, being independent of time, self-affirmation. | |
| From: Friedrich Schelling (On the Essence of Human Freedom [1809], I.7.350), quoted by Andrew Bowie - Introduction to German Philosophy 5 'Reason' | |
| A reaction: Insofar as this says that 'primal being' must be active in character, I love this idea. Not the rest of the idea though! Bowie says this essay clearly influenced Schopenhauer. It looks as if Nietzsche must be read it too. |
| 20957 | We don't choose our characters, yet we still claim credit for the actions our characters perform [Schelling] |
| Full Idea: Nobody has chosen their character; and yet this does not stop anybody attributing the action which follows from his character to themself as a free action. | |
| From: Friedrich Schelling (The Ages of the World [1810], I.93) | |
| A reaction: This pinpoints a very nice ambivalence about our attitudes to our own characters. We all have some pride and shame about who we are, without having chosed who we are. At least when we are young. But we make the bed we lie in. |
| 22057 | Schelling sought a union between the productivities of nature and of the mind [Schelling, by Bowie] |
| Full Idea: Schelling's philosophy of nature aims to connect nature's 'unconscious productivity' with the mind's 'conscious productivity'. | |
| From: report of Friedrich Schelling (Outline of a System of the Philosophy of Nature [1799]) by Andrew Bowie - German Philosophy: a very short introduction 3 | |
| A reaction: If you have a fairly active view of nature (as Leibniz did), then this is a promising line. I like the unpopular view that the modern idea of spontaneous 'powers' in nature is applicable to explanations of mind. |
| 22031 | Schelling made organisms central to nature, because mere mechanism could never produce them [Schelling, by Pinkard] |
| Full Idea: Schelling made the image of the 'organism' central to his conception of nature, arguing that merely mechanical processes could never produce 'life' (as a self-producing, self-sustaining, self-directing process). | |
| From: report of Friedrich Schelling (Outline of a System of the Philosophy of Nature [1799]) by Terry Pinkard - German Philosophy 1760-1860 08 | |
| A reaction: At that date this seems a reasonable claim, but subsequent biochemistry has undermined it. |
| 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. |
| 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). |
