1. Philosophy / F. Analytic Philosophy / 4. Conceptual Analysis
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.
2. Reason / E. Argument / 1. Argument
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.
7. Existence / B. Change in Existence / 1. Nature of Change
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.
7. Existence / B. Change in Existence / 2. Processes
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.
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.
7. Existence / D. Theories of Reality / 1. Ontologies
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.
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.
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.
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.
7. Existence / E. Categories / 2. Categorisation
Even fairly simple animals make judgements based on categories [Gelman]
     Full Idea: All organisms form categories: even mealworms have category-based preferences, and higher-order animals such as pigeons or octopi can display quite sophisticated categorical judgements.
     From: Susan A. Gelman (The Essential Child [2003], 01 'Prelims')
     A reaction: [She cites some 1980 research to support this] This comes as no surprise, as I take categorisation as almost definitive of what a mind is. My surmise is that some sort of 'labelling' system is at the heart of it (like Googlemail labels!).
Children accept real stable categories, with nonobvious potential that gives causal explanations [Gelman]
     Full Idea: By five children assume that a variety of categories have rich inductive potential, are stable over outward transformations, include crucial nonobvious properties, have innate potential, privilege causal features, can be explained causally, and are real.
     From: Susan A. Gelman (The Essential Child [2003], 06 'Intro')
     A reaction: This is Gelman's helpful summary of the findings of research on childhood essentialising, and says the case for this phenomenon is 'compelling'.
8. Modes of Existence / C. Powers and Dispositions / 1. Powers
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).
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.
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!
8. Modes of Existence / C. Powers and Dispositions / 2. Powers as Basic
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!
8. Modes of Existence / C. Powers and Dispositions / 5. Powers and Properties
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.
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?
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / b. Dispositions and powers
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.
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'.
9. Objects / A. Existence of Objects / 1. Physical Objects
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.
9. Objects / D. Essence of Objects / 1. Essences of Objects
In India, upper-castes essentialize caste more than lower-castes do [Gelman]
     Full Idea: The notion of caste in India is more essentialized among upper-caste than lower-caste individuals.
     From: Susan A. Gelman (The Essential Child [2003], 08 'Intro')
     A reaction: In a book defending fairly innate essentialism in the human race, Gelman offers this point as a warning that large cultural ingredients can be involved. Racism is the classic difficulty with essentialism.
Essentialism is either natural to us, or an accident of our culture, or a necessary result of language [Gelman]
     Full Idea: The two views contrasting with essentialism naturally emerging in childhood are the claim that essentialism is a historical accident emerging from Western philosophy, and that essentialism is an inherent consequence of naming things.
     From: Susan A. Gelman (The Essential Child [2003], 01 'Background')
     A reaction: Helpful. I take Idea 15682 to rule out the idea that it is just a feature of western culture. I can't conceive of early man surviving without essentialism. I don't think it rules out the naming view. Animals may do what emerges in us as full 'naming'.
Children's concepts include nonobvious features, like internal parts, functions and causes [Gelman]
     Full Idea: Children incorporate a variety of nonobvious features into their concepts, including internal parts, functions, causes, and ontological distinctions.
     From: Susan A. Gelman (The Essential Child [2003], 01 'Prelims')
     A reaction: This remark sums up the general thesis of her book, which she supports with a wealth of first-hand evidence. It supports my view, that the desire and need for explanation is at the root of essentialist concepts. It's hard wired in us.
9. Objects / D. Essence of Objects / 2. Types of Essence
Essentialism: real or representational? sortal, causal or ideal? real particulars, or placeholders? [Gelman]
     Full Idea: We map types of essentialism by asking is it in the world or in our representations, is it sortal or causal or ideal, and is it specific particulars or placeholders for the unknown?
     From: Susan A. Gelman (The Essential Child [2003], 01 'Prelims')
     A reaction: I am struck by the way that this practising experimental psychologist gets to ask questions and make distinctions much more extensively than most armchair philosophers on the subject. She focuses on the representational, causal, placeholder view.
9. Objects / D. Essence of Objects / 5. Essence as Kind
Essentialism says categories have a true hidden nature which gives an object its identity [Gelman]
     Full Idea: Essentialism is the view that categories have an underlying reality or true nature that one cannot observe directly but that gives an object its identity.
     From: Susan A. Gelman (The Essential Child [2003], 01 'Intro')
     A reaction: I think the introduction of categories here is a misunderstanding. Does an uncategorisable thing therefore have no identity (even though it has properties)? If categories give objects their identity, what gives categories their identity?
Sortals are needed for determining essence - the thing must be categorised first [Gelman]
     Full Idea: I suggest that sortals are likewise required for determining essence. One cannot answer the question 'What is the essence of this?' without supplying the sortal - of this 'what'.
     From: Susan A. Gelman (The Essential Child [2003], 01 'Prelims')
     A reaction: I remain baffled by this view. I take the category to be an inductive generalisation from other similar individuals. It can't get off the ground if you don't start with the individuals. Sortals are just a shorthand.
Kind (unlike individual) essentialism assumes preexisting natural categories [Gelman]
     Full Idea: With kind essentialism the person assumes that the world is divided up into preexisting natural categories. Individual essentialism seems not to require any such commitment to kind realism.
     From: Susan A. Gelman (The Essential Child [2003], 06 'Essentialism')
     A reaction: This pinpoints my difficulty: how do we decide whether some category or attributed essence is part of a preexisting natural kind? Some natural kinds are self-evident, like water (roughly), but others need subtle teasing out. How is the teasing done?
9. Objects / D. Essence of Objects / 7. Essence and Necessity / c. Essentials are necessary
Kinship is essence that comes in degrees, and age groups are essences that change over time [Gelman]
     Full Idea: Kinship is essentialized, but admits of degrees, ...and people can be essentialist even about categories they do not view as fixed over time, such as age groupings.
     From: Susan A. Gelman (The Essential Child [2003], 03 'Summary')
     A reaction: Given my notion of essence are necessarily explanatory, I embrace both of these points. Being very athletic comes in degrees, and changes over times.
9. Objects / D. Essence of Objects / 14. Knowledge of Essences
Essentialism comes from the cognitive need to categorise [Gelman]
     Full Idea: Essentialism has its source in the cognitive requirement of categorization in certain domains - particularly as they affect the young learner.
     From: Susan A. Gelman (The Essential Child [2003], 01 'Essentialist')
     A reaction: I think the phenomenon is better understood as part of the cognitive requirement to understand and explain. Categorisation is just one way to aid explanation. Children try to understand (essentially) a new animal without categorisation.
We found no evidence that mothers teach essentialism to their children [Gelman]
     Full Idea: We found no evidence that mothers teach essentialism to their children. ...Mothers teach children about kinds, not about essences, and mothers help children identify which categories are richly structured.
     From: Susan A. Gelman (The Essential Child [2003], 07 'Conclusions')
     A reaction: This is a psychologist who specialises in this topic. If you think essentialism is inculcated by a our culture, you will have to blame the fathers.
9. Objects / D. Essence of Objects / 15. Against Essentialism
Essentialism is useful for predictions, but it is not the actual structure of reality [Gelman]
     Full Idea: Essentialism is a reasoning heuristic that allows us to make fairly good predictions much of the time, but it should not be confused with the structure of reality.
     From: Susan A. Gelman (The Essential Child [2003], 11 'Discussion')
     A reaction: She particularly cites biology as the area where it might be inaccurate. I'm beginning to think that the operations of induction are the place to look for an good understanding of essentialism.
9. Objects / E. Objects over Time / 4. Four-Dimensionalism
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).
9. Objects / E. Objects over Time / 12. Origin as Essential
Peope favor historical paths over outward properties when determining what something is [Gelman]
     Full Idea: People favor historical paths over outward properties when determining what something is. ...An object looking like a knife is less likely to be called 'a knife' if it is described as having been created by accident.
     From: Susan A. Gelman (The Essential Child [2003], 06 'Essentialism')
     A reaction: I like this because it talks, suggestively, of 'historical paths' rather than of 'origin'. Thus we might judge a person's identity by their traumatic experience rather than by their birth. This doesn't challenge necessity of origin, but affects labels.
11. Knowledge Aims / A. Knowledge / 2. Understanding
There is intentional, mechanical, teleological, essentialist, vitalist and deontological understanding [Gelman]
     Full Idea: The modes of understanding (or modes of construal) which have been proposed are intentional, mechanical, teleological, essentialist, vitalist (perhaps), and deontological.
     From: Susan A. Gelman (The Essential Child [2003], 11 'Broadening')
     A reaction: She cites psychological research to support this, and calls it 'a relatively small number' of modes. Compare Aristotle's four modes of cause/explanation.
12. Knowledge Sources / E. Direct Knowledge / 4. Memory
Memories often conform to a theory, rather than being neutral [Gelman]
     Full Idea: Memory is notorious for conforming to theory (rather than memory being a neutral source of information).
     From: Susan A. Gelman (The Essential Child [2003], 09 'Theory')
     A reaction: This observation by a psychologist is music to sceptics about objectivity. Memory is so fundamental to our basic epistemology that it could even be the nature of thought itself.
14. Science / C. Induction / 1. Induction
Inductive success is rewarded with more induction [Gelman]
     Full Idea: Inductive success is rewarded with more induction.
     From: Susan A. Gelman (The Essential Child [2003], 11 'Broadening')
     A reaction: I love this one. Neat, accurate, and central to how we understand the world. I take inductive success to be stored as labels, concepts, categories, words and general truths, which are then our resource for further attempts.
14. Science / C. Induction / 3. Limits of Induction
Children overestimate the power of a single example [Gelman]
     Full Idea: We suggest that children overestimate the power of a single example.
     From: Susan A. Gelman (The Essential Child [2003], 06 'The role')
     A reaction: This conclusion arises from extensive psychological research. 'My grandma smoked, and she lived to be 97' - adults do this too. Wittgenstein says assuming other minds because of your own is induction from one example!
Children make errors in induction by focusing too much on categories [Gelman]
     Full Idea: Because of their narrow focus, children's sensitivity to categories as the basis of induction is a reasoning bias that, though useful much of the time, results in systematic errors.
     From: Susan A. Gelman (The Essential Child [2003], 06 'The role')
     A reaction: This is the bad sense of 'essentialism' which worries its opponents. Presumably, though, my favoured scientific essentialism will be 'scientific', and avoid this problem. The relation between categories and induction needs to be clear.
14. Science / D. Explanation / 1. Explanation / a. Explanation
People tend to be satisfied with shallow explanations [Gelman]
     Full Idea: People tend to be satisfied with rather shallow explanations.
     From: Susan A. Gelman (The Essential Child [2003], 06 'Is essentialism')
     A reaction: She cites some psychological research to support this. Pretty obvious really. I take the so-called 'scientific method' to be nothing more than ceasing to be satisfied with such shallowness.
18. Thought / A. Modes of Thought / 4. Folk Psychology
Folk essentialism rests on belief in natural kinds, in hidden properties, and on words indicating structures [Gelman]
     Full Idea: The three components of essentialism as a folk belief are the idea that certain categories are natural kinds, the idea that some unobservable property causes the way things are, and the idea that words reflect real structures.
     From: Susan A. Gelman (The Essential Child [2003], 01 'Prelims')
18. Thought / D. Concepts / 3. Ontology of Concepts / a. Concepts as representations
Labels may indicate categories which embody an essence [Gelman]
     Full Idea: Labels may signal categories that are believed to embody an essence.
     From: Susan A. Gelman (The Essential Child [2003], 02 'Privileged')
     A reaction: This is quoted by her, as a summary of a substantial body of research which she endorses. I cite it because it pinpoints my own view. I take 'labels' to be basic to minds, as organisers of thought, and this ties essences to labels. Satisfying picture.
18. Thought / D. Concepts / 4. Structure of Concepts / a. Conceptual structure
Causal properties are seen as more central to category concepts [Gelman]
     Full Idea: Properties that enter into causally meaningful links are better remembered and are treated as more central to the category than properties that are not causally meaningful.
     From: Susan A. Gelman (The Essential Child [2003], 05 'Causation2')
     A reaction: This is a summary of considerable psychological research. This account not only sounds plausible, but would fit better withy why we form concepts and categories in the first place. We are trying to relate to the causations of nature.
18. Thought / D. Concepts / 4. Structure of Concepts / d. Concepts as prototypes
Categories are characterized by distance from a prototype [Gelman]
     Full Idea: On prototype views, categories are characterized by distance from a prototype.
     From: Susan A. Gelman (The Essential Child [2003], 05 'Causation')
     A reaction: Gelman observes that this view makes no reference to any causal features of things. This cuts them off from using underlying essences in the process of categorisation and concept-formation. How do you spot a prototype, with no category?
18. Thought / D. Concepts / 4. Structure of Concepts / f. Theory theory of concepts
Theory-based concepts use rich models to show which similarities really matter [Gelman]
     Full Idea: Theory-based approaches to categories are a response to the limitations of mere similarities holding the category together, and require knowledge-rich explanatory models to say which features are more central to a concept.
     From: Susan A. Gelman (The Essential Child [2003], 05 'Causation1')
     A reaction: I see a promising account in linking theory theory to essentialism. For a physical object (or even for a process) infer a structure, and then identify what is most important in that structure. That gives you your stable, agreed concept.
18. Thought / D. Concepts / 5. Concepts and Language / c. Concepts without language
Prelinguistic infants acquire and use many categories [Gelman]
     Full Idea: Language does not appear to be necessary for forming categories, since prelinguistic infants acquire many categories, and even use categories to form inferences about unknown properties.
     From: Susan A. Gelman (The Essential Child [2003], 08 'Intro')
     A reaction: She cites lots of research in support of this claim. The idea may come as a surprise to some people, but not to me. I take it that categorisation is what a brain is for, including animal brains.
26. Natural Theory / B. Natural Kinds / 3. Knowing Kinds
One sample of gold is enough, but one tree doesn't give the height of trees [Gelman]
     Full Idea: We can confidently determine the chemical composition of gold from just a single sample, but we cannot determine the height of trees from just a single tree.
     From: Susan A. Gelman (The Essential Child [2003], 06 'The role')
     A reaction: The tricky word here is 'confidently'. If you meet one Latvian who is nice, do you assume they are all nice? At what point do you decide gold etc. really are natural kinds, where one sample tells all? Evolution of species...
26. Natural Theory / B. Natural Kinds / 5. Reference to Natural Kinds
Nouns seem to invoke stable kinds more than predicates do [Gelman]
     Full Idea: Children judged personal characteristics as more stable when they were referred to by a noun ('She is a carrot eater') than by a verbal predicate ('She eats carrots whenever she can')
     From: Susan A. Gelman (The Essential Child [2003], 08 'Naming')
     A reaction: This fits with my feeling that 'labels' are the basis of how the mind works. The noun invokes a genuine category of thing, where a predicate attaches to some preselected category ('she'). Gelman says names encourage inductions.
26. Natural Theory / C. Causation / 1. Causation
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.
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.
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
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.
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / a. Scientific essentialism
Essentialism encourages us to think about the world scientifically [Gelman]
     Full Idea: Essentialism encourages a 'scientific' mindset in thinking about the natural world, a belief that intensive study of a natural domain will yield ever more underlying properties.
     From: Susan A. Gelman (The Essential Child [2003], 11 'Intro')
     A reaction: Maybe scientists must be committed to essences, the way mathematicians must be committed to numbers? This idea spendidly opposes the doubts expressed by Popper.
Essentialism doesn't mean we know the essences [Gelman]
     Full Idea: Essentialism does not entail that people know what the essence is.
     From: Susan A. Gelman (The Essential Child [2003], 09 'Theory')
     A reaction: This is a fundamental and (I would say) fairly obvious point, but it needs to be made to the more passionate opponents of essentialism.
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / c. Essence and laws
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).
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / d. Knowing essences
Essentialism starts from richly structured categories, leading to a search for underlying properties [Gelman]
     Full Idea: If my speculations are correct, then essentialism starts out strictly as a belief that many categories are richly structured kinds, then additionally becomes a search for underlying inherent properties.

     A reaction: This is her summary of extensive essentialist research among children. She favours the priority of kinds and categories. We actually change taxonomies on the basis of revisions in our accounts of essence. Science negotiates.

A major objection to real essences is the essentialising of social categories like race, caste and occupation [Gelman]
     Full Idea: One major argument against the view that essences are real is the rampant essentializing of categories that are socially constructed (such as race, caste and occupation).
     From: Susan A. Gelman (The Essential Child [2003], 11 'Is essentialism')
     A reaction: You can't argue with that. It raises the question of whether the approach of scientific essentialism has any value in the social, rather than physical, sciences. We jokingly essentialise groups of people such as referees or Oxonians.
