9. Objects / A. Existence of Objects / 1. Physical Objects
Things are constructs for tracking patterns (and not linguistic, because animals do it) [Ladyman/Ross]
     Full Idea: Individual things are constructs built for second-best tracking of real patterns. They are not necessarily linguistic constructions, since some non-human animals almost certainly cognitively construct them.
     From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.5)
     A reaction: Delighted to see animals making an appearance. Fans of language-based metaphysics please note. If they are fictional constructs, why do they do such a good job of tracking? What generates the 'superficial' appearance that there are objects?
9. Objects / A. Existence of Objects / 5. Individuation / a. Individuation
Maybe individuation can be explained by thermodynamic depth [Ladyman/Ross]
     Full Idea: Scientists have developed principles for understanding individuation in terms of the production of thermodynamic depth.
     From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.5)
     A reaction: [They cite J.Collier for this view] Interesting, even though I don't really understand 'thermodynamic depth'. Ladyman and Ross reject it, but there is a whiff of a theory of individuation from within physics.
9. Objects / A. Existence of Objects / 6. Nihilism about Objects
Physics seems to imply that we must give up self-subsistent individuals [Ladyman/Ross]
     Full Idea: There is growing convergence among philosophers of physics that physics motivates abandonment of a metaphysics that posits fundamental self-subsistent individuals.
     From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.4)
     A reaction: They cite fermions as an example, which only seem to be given an identity by the relations into which they enter. It is a bit cheeky to simultaneously offer this idea, and despise van Inwagen and Merricks for the same object nihilism.
There is no single view of individuals, because different sciences operate on different scales [Ladyman/Ross]
     Full Idea: There is no single account of what individuals there are because, we argue, the special sciences may disagree about the bounds and status of individuals since they describe the world at different scales.
     From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.8)
     A reaction: This seems to deny that nature has actual joints, and so seems to me to be a form of anti-realism (which they would deny). Why shouldn't there be a single view which unites all of these special sciences?
There are no cats in quantum theory, and no mountains in astrophysics [Ladyman/Ross]
     Full Idea: At the quantum scale there are no cats; at scales appropriate for astrophysics there are no mountains.
     From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.2)
     A reaction: I don't find this convincing. Since cats are made of quantised entities, they do exist in that world, but are of little interest when trying to understand it. Similarly, astrophysicists hardly deny the existence of mountains!
9. Objects / B. Unity of Objects / 1. Unifying an Object / b. Unifying aggregates
Parts must belong to a created thing with a distinct form [Plato]
     Full Idea: The part would not be the part of many things or all, but of some one character ['ideas'] and of some one thing, which we call a 'whole', since it has come to be one complete [perfected] thing composed [created] of all.
     From: Plato (Parmenides [c.364 BCE], 157d)
     A reaction: A serious shot by Plato at what identity is. Harte quotes it (125) and shows that 'character' is Gk 'idea', and 'composed' will translate as 'created'. 'Form' links this Platonic passage to Aristotle's hylomorphism.
9. Objects / B. Unity of Objects / 1. Unifying an Object / c. Unity as conceptual
Things are abstractions from structures [Ladyman/Ross]
     Full Idea: Individual things are locally focused abstractions from modal structure.
     From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.4)
     A reaction: I am a fan of the role of abstraction in our understanding of the world, despite my limited progress in trying to explicate the idea. I can't decide whether or not there are any things. A bit basic, that!
9. Objects / C. Structure of Objects / 5. Composition of an Object
The idea of composition, that parts of the world are 'made of' something, is no longer helpful [Ladyman/Ross]
     Full Idea: It is no longer helpful to conceive of either the world, or particular systems of the world that we study in partial isolation, as 'made of' anything at all. …Our target here is the metaphysical idea of composition.
     From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.1)
     A reaction: This is argued by them from the point of view of fundamental physics as the provider of our basic metaphysics about the world. Personally I really really want to know what electrons are made of, but I know no one is going to tell me. They may even laugh.
In Parmenides, if composition is identity, a whole is nothing more than its parts [Plato, by Harte,V]
     Full Idea: At the heart of the 'Parmenides' puzzles about composition is the thesis that composition is identity. Considered thus, a whole adds nothing to an ontology that already includes its parts
     From: report of Plato (Parmenides [c.364 BCE]) by Verity Harte - Plato on Parts and Wholes 2.5
     A reaction: There has to be more to a unified identity that mere proximity of the parts. When do parts come together, and when do they actually 'compose' something?
9. Objects / C. Structure of Objects / 8. Parts of Objects / a. Parts of objects
Plato says only a one has parts, and a many does not [Plato, by Harte,V]
     Full Idea: In 'Parmenides' it is argued that a part cannot be part of a many, but must be part of something one.
     From: report of Plato (Parmenides [c.364 BCE], 157c) by Verity Harte - Plato on Parts and Wholes 3.2
     A reaction: This looks like the right way to go with the term 'part'. We presuppose a unity before we even talk of its parts, so we can't get into contradictions and paradoxes about their relationships.
Anything which has parts must be one thing, and parts are of a one, not of a many [Plato]
     Full Idea: The whole of which the parts are parts must be one thing composed of many; for each of the parts must be part, not of a many, but of a whole.
     From: Plato (Parmenides [c.364 BCE], 157c)
     A reaction: This is a key move of metaphysics, and we should hang on to it. The other way madness lies.
9. Objects / C. Structure of Objects / 8. Parts of Objects / c. Wholes from parts
It seems that the One must be composed of parts, which contradicts its being one [Plato]
     Full Idea: The One must be composed of parts, both being a whole and having parts. So on both grounds the One would thus be many and not one. But it must be not many, but one. So if the One will be one, it will neither be a whole, nor have parts.
     From: Plato (Parmenides [c.364 BCE], 137c09), quoted by Kathrin Koslicki - The Structure of Objects 5.2
     A reaction: This is the starting point for Plato's metaphysical discussion of objects. It seems to begin a line of thought which is completed by Aristotle, surmising that only an essential structure can bestow identity on a bunch of parts.
A sum of things is not a whole if the whole does not support some new generalisation [Ladyman/Ross]
     Full Idea: A nostril, a city and a trumpet solo is not a real pattern, because identification of it supports no generalisations not supported by identification of the three conjuncts considered separately.
     From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.4)
     A reaction: This is a nice try at offering a criterion for unity, but I doubt whether it will work, because an ingenious person could come up with wild generalisations. These three combined make possible a charming new line of poetry.
9. Objects / D. Essence of Objects / 13. Nominal Essence
We treat the core of a pattern as an essence, in order to keep track of it [Ladyman/Ross]
     Full Idea: We focus on diagnostic features of real patterns that we can treat as 'core', which reliably predict that our attention is still tracking the same real pattern. These are Locke's 'essence of particulars', or Putnam's 'hidden structures'.
     From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.5)
     A reaction: They seemed to be ashamed of themselves for proposing this, and call it a 'second-best' epistemological device. They seem to imply that they are useful fictions, but why shouldn't the hidden structures be real? They might both identify and explain.
9. Objects / E. Objects over Time / 1. Objects over Time
A continuous object might be a type, with instances at each time [Ladyman/Ross]
     Full Idea: Why should not 'Napoleon' be a type, of which 'Napoleon in 1805' and 'Napoleon in 1813' are instances?
     From: J Ladyman / D Ross (Every Thing Must Go [2007], 5.6)
     A reaction: That is very nice. That might be a view that suits presentism, where the timed instances never co-exist, and so have the sort of abstract existence that we associate with types.
9. Objects / F. Identity among Objects / 6. Identity between Objects
Two things relate either as same or different, or part of a whole, or the whole of the part [Plato]
     Full Idea: Everything is surely related to everything as follows: either it is the same or different; or, if it is not the same or different, it would be related as part to whole or as whole to part.
     From: Plato (Parmenides [c.364 BCE], 146b)
     A reaction: This strikes me as a really helpful first step in trying to analyse the nature of identity. Two things are either two or (actually) one, or related mereologically.
