| 6319 | Wise people choose inaction and silence [Laozi (Lao Tzu)] |
| Full Idea: The sage keeps to the deed that consists in taking no action and practises the teaching that uses no words. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], I.II.6) | |
| A reaction: Notice that this is an active 'deed', and a positive 'practice'. He is not just recommending indifference and lethargy. Personally I don't find the advice very appealing, but it might be good if you live in 'interesting times'. |
| 6325 | One who knows does not speak; one who speaks does not know [Laozi (Lao Tzu)] |
| Full Idea: One who knows does not speak; one who speaks does not know. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], II.LVI.128) | |
| A reaction: A famous remark, which my western mind finds simply perplexing. It strikes me as wicked selfishness to keep your wisdom to yourself, and not try to persuade others to follow it. We are all in this together, I say. |
| 6321 | Vulgar people are alert; I alone am muddled [Laozi (Lao Tzu)] |
| Full Idea: Vulgar people are alert; I alone am muddled. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], I.XX.47) | |
| A reaction: Personally I think all human beings are deeply perplexed when they actually address their situation, but most people never spend more than a few minutes a year worrying about it. |
| 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. |
| 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. |
| 6328 | To know yet to think that one does not know is best [Laozi (Lao Tzu)] |
| Full Idea: To know yet to think that one does not know is best. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], II.LXXI.173) | |
| A reaction: Tricky. Self-deception doesn't sound like a virtue to me. There are epistemic virtues, and caution about one's own knowledge has to be one of them, but a totally false assessment sounds counter-productive. |
| 6323 | Pursuit of learning increases activity; the Way decreases it [Laozi (Lao Tzu)] |
| Full Idea: In the pursuit of learning one knows more every day; in the pursuit of the Way one does less every day. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], II.XLVII.108) | |
| A reaction: Everything in my culture has raised the status of the pursuit of learning, so that I can hardly comprehend what is proposed by the Way. I don't believe that the Way can be achieved without great learning, but one might move beyond learning. |
| 6331 | Truth is not beautiful; beautiful speech is not truthful [Laozi (Lao Tzu)] |
| Full Idea: Truthful words are not beautiful; beautiful words are not truthful. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], II.LXXXI.194) | |
| A reaction: A sharp disagreement with Keats ('Ode to a Grecian Urn'). A deep and important question, especially in relation to Plato's discussion of rhetoric (where he is very ambivalent). Great mathematics is beautiful. Truth can harsh. On the whole, I disagree. |
| 6330 | One with no use for life is wiser than one who values it [Laozi (Lao Tzu)] |
| Full Idea: It is just because one has no use for life that one is wiser than the man who values life. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], II.LXXV.181a) | |
| A reaction: To have no use for life certainly seems to put a person into a position of superiority, especially when the 'Titanic' is sinking. However, if our lives have no value, I don't know what does. A balance must clearly be struck. |
| 6327 | Do good to him who has done you an injury [Laozi (Lao Tzu)] |
| Full Idea: Do good to him who has done you an injury. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], II.LXIII.148) | |
| A reaction: Compare Idea 6288 (Jesus). People like this really mess up the social contract theory of morality. If they are going to return good for your evil, there doesn't seem much point in helping them, given how much effort is involved. Most peculiar… |
| 23402 | The highest virtue is achieved without effort [Laozi (Lao Tzu)] |
| Full Idea: Those of highest virtue do not strive for virtue, and so they have it. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], 38), quoted by Bryan van Norden - Intro to Classical Chinese Philosophy 8.II.2 | |
| A reaction: Every moralist's dream is the person to whom virtue comes so naturally that no thought is required. This says they don't even notice it; Aristotle says they simply enjoying behaving virtuously. |
| 6324 | To gain in goodness, treat as good those who are good, and those who are not [Laozi (Lao Tzu)] |
| Full Idea: Those who are good I treat as good; those who are not good I also treat as good; in doing so I gain in goodness. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], II.XLIX.111) | |
| A reaction: Socrates (idea 346) and Jesus (Idea 6288) had similar ideas. Who, though, is going to administer justice, and where is the idea that people 'deserve' good or ill treatment? Schoolteachers should treat all children as if they were good. |
| 6322 | There is no crime greater than having too many desires [Laozi (Lao Tzu)] |
| Full Idea: There is no crime greater than having too many desires. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], II.XLVI.104) | |
| A reaction: It seems harsh to call this a 'crime', given that no one is likely to choose to have 'too many' desires. The crime is in deciding to stimulate desire to excess, or deciding to show no sensible restraint. |
| 6320 | The best rulers are invisible, the next admired, the next feared, and the worst are exploited [Laozi (Lao Tzu)] |
| Full Idea: The best of all rulers is but a shadowy presence to his subjects; next comes the ruler they love and praise; next comes one they fear; next comes one with whom they take liberties. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], I.XVII.39) | |
| A reaction: This fits our understanding of football referees to perfection. It might apply to anyone doing a vital adminstrative job, such as compiling a school timetable. It is hard, though, to accept anonymity as a mark of success. |
| 6329 | People are hard to govern because authorities love to do things [Laozi (Lao Tzu)] |
| Full Idea: It is because those in authority are too fond of action that the people are difficult to govern. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], II.LXXV.181) | |
| A reaction: I love this. It should be on the wall of every human institution in our civilization. How the heart sinks at the prospect of a 'new initiative'. Not that I am against action; it is just important to recognise that inaction is sometimes the best option. |
| 6326 | The better known the law, the more criminals there are [Laozi (Lao Tzu)] |
| Full Idea: The better known the laws and edicts, the more thieves and robbers there are. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], II.LVII.132) | |
| A reaction: Nice. I link this with my favourite moral maxim from Democritus (Idea 519). The idea is that continual emphasis on what you should not do fills the mind with evil possibilities. Moral perfection must start by taking goodness for granted. |
| 23401 | A military victory is not a thing of beauty [Laozi (Lao Tzu)] |
| Full Idea: A military victory is not a thing of beauty. | |
| From: Laozi (Lao Tzu) (Daodejing (Tao Te Ching) [c.530 BCE], 31), quoted by Bryan van Norden - Intro to Classical Chinese Philosophy 8.II.1 | |
| A reaction: Should be written on the wall of every military academy and barracks. |
| 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). |
