Single Idea 14099

[filed under theme 19. Language / E. Analyticity / 1. Analytic Propositions ]

Full Idea

It sounds right to say that Fred's being a bachelor consists in (reduces to) being an unmarried male, but slightly off to say that Fred's being an unmarried male consists in (or reduces to) being a bachelor. There is a corresponding explanatory asymmetry.

Gist of Idea

'Bachelor' consists in or reduces to 'unmarried' male, but not the other way around

A Reaction

This emerging understanding of the asymmetry of the idea shows that we are not just dealing with a simple semantic identity. Our concepts are richer than our language. He adds that a ball could be blue in virtue of being cerulean.


The 29 ideas from Gideon Rosen

Nowadays abstractions are defined as non-spatial, causally inert things [Rosen]
Chess may be abstract, but it has existed in specific space and time [Rosen]
Sets are said to be abstract and non-spatial, but a set of books can be on a shelf [Rosen]
Functional terms can pick out abstractions by asserting an equivalence relation [Rosen]
Abstraction by equivalence relationships might prove that a train is an abstract entity [Rosen]
The Way of Abstraction used to say an abstraction is an idea that was formed by abstracting [Rosen]
Conflating abstractions with either sets or universals is a big claim, needing a big defence [Rosen]
How we refer to abstractions is much less clear than how we refer to other things [Rosen]
'Metaphysical' modality is the one that makes the necessity or contingency of laws of nature interesting [Rosen]
Metaphysical necessity is absolute and universal; metaphysical possibility is very tolerant [Rosen]
Something may be necessary because of logic, but is that therefore a special sort of necessity? [Rosen]
A Meinongian principle might say that there is an object for any modest class of properties [Rosen]
Pairing (with Extensionality) guarantees an infinity of sets, just from a single element [Rosen]
A proposition is 'correctly' conceivable if an ominiscient being could conceive it [Rosen]
The MRL view says laws are the theorems of the simplest and strongest account of the world [Rosen]
Combinatorial theories of possibility assume the principles of combination don't change across worlds [Rosen]
Sets, universals and aggregates may be metaphysically necessary in one sense, but not another [Rosen]
Non-Standard Metaphysical Necessity: when ¬P is incompatible with the nature of things [Rosen]
Standard Metaphysical Necessity: P holds wherever the actual form of the world holds [Rosen]
Philosophers are often too fussy about words, dismissing perfectly useful ordinary terms [Rosen]
An 'intrinsic' property is one that depends on a thing and its parts, and not on its relations [Rosen]
The excellent notion of metaphysical 'necessity' cannot be defined [Rosen]
Facts are structures of worldly items, rather like sentences, individuated by their ingredients [Rosen]
Explanations fail to be monotonic [Rosen]
Things could be true 'in virtue of' others as relations between truths, or between truths and items [Rosen]
Figuring in the definition of a thing doesn't make it a part of that thing [Rosen]
An acid is just a proton donor [Rosen]
'Bachelor' consists in or reduces to 'unmarried' male, but not the other way around [Rosen]
Are necessary truths rooted in essences, or also in basic grounding laws? [Rosen]
