Natural things observe certain laws, and things cannot do otherwise if they retain their forms [Hooker,R]
     Full Idea: Things natural …do so necessarily observe their certain laws, that as long as they keep those forms which give them their being they cannot possibly be apt or inclinable to do otherwise than they do.
     From: Richard Hooker (Of the Laws of Ecclesiastical Polity [1593], 1.3.4), quoted by Marc Lange - Laws and Lawmakers 1.2
     A reaction: Cited by some as the beginnings of the idea of 'laws of nature', but it is striking that Hooker says the laws are controlled by 'forms' (which are Aristotelian essences). This is an essentialist view of laws, not a regularity or divine power one.
I am not saying gravity is essential to bodies [Newton]
     Full Idea: I am by no means asserting that gravity is essential to bodies.
     From: Isaac Newton (Principia Mathematica [1687], Bk 3 Rule 3)
     A reaction: Notice that in Idea 17009 he does not rule out gravity being essential to bodies. This is Newton's intellectual modesty (for which he is not famous).
I won't object if someone shows that gravity consistently arises from the action of matter [Newton]
     Full Idea: If someone explains gravity along with all its laws by the action of some subtle matter, and shows that the motion of the planets and comets will not be disturbed by this matter, I shall be far from objecting.
     From: Isaac Newton (Letters to Leibniz 1 [1693], 1693.10.16)
     A reaction: Important if you think that Newton is the hero of the descriptive regularity theory of laws. Newton probably thought laws came from God, but he wouldn't object to Leibniz's view, that God planted the laws within the matter.
Each of the infinite possible worlds has its own laws, and the individuals contain those laws [Leibniz]
     Full Idea: As there are an infinity of possible worlds, there are also an infinity of laws, some proper to one, another to another, and each possible individual of any world contains in its own notion the laws of its world.
     From: Gottfried Leibniz (On Sufficient Reason [1686], p.95)
     A reaction: Hence Leibniz is not really a scientific essentialist, in that he doesn't think the laws arise out of the nature of the matter consituting the world. I wonder if the primitive matter of bodies which attaches to the monads is the same in each world?
Gravity is within matter because of its structure, and it can be explained. [Leibniz]
     Full Idea: I believe that both gravity and elasticity are in matter only because of the structure of the system and can be explained mechanically or through impulsion.
     From: Gottfried Leibniz (Letters to Thomas Burnett [1703], 1699 draft)
     A reaction: The significance of this remark is that gravity is held (in full knowledge of Newton's work) to be within matter, and not imposed from the outside. I believe we now postulate a particle as part of the explanation.
The only permanence in things, constituting their substance, is a law of continuity [Leibniz]
     Full Idea: Nothing is permanent in things except the law itself, which involves a continuous succession ...The fact that a certain law persists ...is the very fact that constitutes the same substance.
     From: Gottfried Leibniz (Letters to Burcher De Volder [1706], 1704)
     A reaction: Aristotle and Leibniz are the very clear ancestors of modern scientific essentialism. I've left out a few inconvenient bits, about containing 'the whole universe', and containing all 'future states'. For Leibniz, laws are entirely rooted in things.
In addition to laws, God must also create appropriate natures for things [Leibniz]
     Full Idea: It isn't sufficient to say that God has made a general law, for in addition to the decree there has also to be a natural way of carrying it out. It is necessary, that is, that what happens should be explicable in terms of the God-given nature of things.
     From: Gottfried Leibniz (Letter to the Editor about Bayle [1698], p.205)
     A reaction: Thus Leibniz is an ancestor of scientific essentialism, but he was too frightened to take the next step, which is to see that once God has endowed the natures, he doesn't need to wield his laws as well. The natures will do the whole job.
Leibniz wanted to explain motion and its laws by the nature of body [Leibniz, by Garber]
     Full Idea: Leibniz seeks the big picture: the nature of body as a grounding for an account of motion and its laws.
     From: report of Gottfried Leibniz (works [1690]) by Daniel Garber - Leibniz:Body,Substance,Monad 4
     A reaction: Garber is contrasting this with Newton's approaches, who just pleads ignorance of the bigger picture. Essentialists must beware of inventing a bigger picture simply because they desperately want a bigger picture.
The law within something fixes its persistence, and accords with general laws of nature [Leibniz]
     Full Idea: Nothing is permanent in a substance except the law itself which determines the continuous succession of its states and accords within the individual substance with the laws of nature that govern the whole world.
     From: Gottfried Leibniz (works [1690], G II:263), quoted by David Wiggins - Sameness and Substance 3 epig
     A reaction: An interesting link between the law-of-series within a substance, and the broader concept of laws outside it.
Laws are the necessary relations that derive from the nature of things [Montesquieu]
     Full Idea: Laws, in the broadest meaning of the term, are the necessary relations that derive from the nature of things.
     From: Baron de Montesquieu (The Spirit of the Laws (rev. 1757) [1748], 01.01)
     A reaction: Montesquieu is about to discuss social laws, but this is the clearest statement I have ever met of the essentialist view of the laws of nature.
Things are strong or weak, and do not behave regularly or according to rules or compulsions [Nietzsche]
     Full Idea: 'Things' do not behave regularly, not according to a rule: things are our fiction, and nor do they behave under the compulsion of necessity. That something is as it is, as strong or as weak, is not the consequence of obeying or rules or compulsion.
     From: Friedrich Nietzsche (Writings from Late Notebooks [1887], 14[79])
     A reaction: I'm not sure about the denial of 'things', given that they are then said to be strong or weak, but Nietzsche seems to have had the key insight of modern essentialism, that the so-called 'laws' are merely the outcome of the inner natures of things.
Chemical 'laws' are merely the establishment of power relations between weaker and stronger [Nietzsche]
     Full Idea: I take care not to talk of chemical 'laws'. It is rather a matter of the absolute establishment of power relations: the stronger becomes master of the weaker to the extent that the weaker cannot assert its autonomy - there is no respect for 'laws'.
     From: Friedrich Nietzsche (Writings from Late Notebooks [1887], 36[18])
     A reaction: This links Nietzsche's will to power with Locke's talk of physical powers, and both point towards an essentialist view of natural laws, rather than seeing laws as something imposed from outside on nature.
All motions and 'laws' are symptoms of inner events, traceable to the will to power [Nietzsche]
     Full Idea: One must understand all motion, all 'appearances', all 'laws' as mere symptoms of inner events. ...all the functions of animal and organic life can be traced back to the will to power.
     From: Friedrich Nietzsche (Writings from Late Notebooks [1887], 36[31])
     A reaction: Nietzsche must be the first philosopher to put inverted commas round the word 'law', referring to nature.
Causal laws are summaries of powers [Martin,CB]
     Full Idea: Causal laws are summaries of what entities are capable and incapable of.
     From: C.B. Martin (The Mind in Nature [2008], 02.8)
     A reaction: That's a pretty good formulation. Personally I favour a Humean analysis, perhaps along Lewis's lines, but on a basis of real powers. This remark of Martin's has got me rethinking.
A hierarchy of natural kinds is elaborate ontology, but needed to explain natural laws [Ellis]
     Full Idea: The hierarchy of natural kinds proposed by essentialism may be more elaborate than is strictly required for purposes of ontology, but it is necessary to explain the necessity of the laws of nature, and the universal applicability of global principles.
     From: Brian Ellis (Katzav on limitations of dispositions [2005], 91)
     A reaction: I am all in favour of elaborating ontology in the name of best explanation. There seem, though, to be some remaining ontological questions at the point where the explanations of essentialism run out.
Dispositions are not general laws, but laws of the natures of individual entities [Place]
     Full Idea: Dispositions are the substantive laws, not, as for Armstrong, of nature in general, but of the nature of individual entities whose dispositional properties they are.
     From: Ullin T. Place (Intentionality and the Physical: reply to Mumford [1999], 6)
     A reaction: [He notes that Nancy Cartwright 1989 agrees with him] I like this a lot. I tend to denegrate 'laws', because of their dubious ontological status, but this restores laws to the picture, in the place where they belong, in the stuff of the world.
Laws of nature state necessary connections of things, events and properties, based on models of mechanisms [Harré]
     Full Idea: A law of nature tells us what kinds of things, events and properties (all else being equal) go along with what. The 'must' of natural necessity has its place here because it is bound up with a model or analogy representing generative mechanisms.
     From: Rom Harré (Laws of Nature [1993], 5)
     A reaction: This is Harré's final page summary of laws. I agree with it. I would say that the laws are therefore descriptive, of the patterns of behaviour that arise when generative mechanisms meet. Maybe laws concern 'transformations'.
In lawful universal statements (unlike accidental ones) we see why the regularity holds [Harré/Madden]
     Full Idea: The only sure way of distinguishing lawful and accidental universal statements is to point out that in the former cases we see why the regularity must hold, while in the latter case we do not.
     From: Harré,R./Madden,E.H. (Causal Powers [1975], 2.II)
     A reaction: I agree with this, and also take it to be the solution to the problem of induction. That smoking causes cancer will be a true generalisation but not a law, until we see clearly why it happens.
Laws of nature are just the possession of essential properties by natural kinds [Mumford]
     Full Idea: If dispositional essentialism is granted, then there is a law of nature wherever there is an essential property of a natural kind; laws are just the havings of essential properties by natural kinds.
     From: Stephen Mumford (Laws in Nature [2004], 07.2)
     A reaction: [He is expounding Ellis's view]
Most laws supervene on fundamental laws, which are explained by basic powers [Bird, by Friend/Kimpton-Nye]
     Full Idea: According to Bird, non-fundamental laws supervene on fundamental laws, and so are ultimately explained by fundamental powers.
     From: report of Alexander Bird (Nature's Metaphysics [2007]) by Friend/Kimpton-Nye - Dispositions and Powers 3.6.1
     A reaction: This looks like the picture I subscribe to. Roughly, fundamental laws are explained by powers, and non-fundamental laws are explained by properties, which are complexes of powers. 'Fundamental' may not be a precise term!
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).
Laws are relations of kinds, quantities and qualities, supervening on the essences of a domain [Vetter]
     Full Idea: The laws of a domain are the fundamental, general explanatory relationships between kinds, quantities, and qualities of that domain, that supervene upon the essential natures of those things.
     From: Barbara Vetter (Dispositional Essentialism and the Laws of Nature [2012], 9.3)
     A reaction: Hm. How small can the domain be? Can it embrace the multiverse? Supervenience is a rather weak relationship. How about 'are necessitated/entailed by'? Are the relationships supposed to do the explaining? I would have thought the natures did that.
