Single Idea 15169

[filed under theme 1. Philosophy / E. Nature of Metaphysics / 6. Metaphysics as Conceptual ]

Full Idea

Metaphysics, for the conventionalist, is not a matter of trying to see deeply into the structure of mind-independent reality, but of trying to clarify the way we actually speak and think, and perhaps negotiating ways of doing this to our best advantage.

Gist of Idea

Metaphysics is clarifying how we speak and think (and possibly improving it)

A Reaction

Note that he is still allowing space for 'revisionary' as well as for 'descriptive' metaphysics. I can't wholly accept this, as I really do think we can have some deep insights into reality, but Sidelle is articulating a large part of the truth.


The 22 ideas from 'Necessity, Essence and Individuation'

Necessary a posteriori is conventional for necessity and nonmodal for a posteriority [Sidelle, by Sider]
Empiricism explores necessities and concept-limits by imagining negations of truths [Sidelle]
A priori knowledge is entirely of analytic truths [Sidelle]
That water is essentially H2O in some way concerns how we use 'water' [Sidelle]
Causal reference seems to get directly at the object, thus leaving its nature open [Sidelle]
Metaphysics is clarifying how we speak and think (and possibly improving it) [Sidelle]
We seem to base necessities on thought experiments and imagination [Sidelle]
Clearly, essential predications express necessary properties [Sidelle]
That the essence of water is its microstructure is a convention, not a discovery [Sidelle]
The necessary a posteriori is statements either of identity or of essence [Sidelle]
The individuals and kinds involved in modality are also a matter of convention [Sidelle]
A thing doesn't need transworld identity prior to rigid reference - that could be a convention of the reference [Sidelle]
Evaluation of de dicto modalities does not depend on the identity of its objects [Sidelle]
There doesn't seem to be anything in the actual world that can determine modal facts [Sidelle]
Being a deepest explanatory feature is an actual, not a modal property [Sidelle]
Contradictoriness limits what is possible and what is imaginable [Sidelle]
To know empirical necessities, we need empirical facts, plus conventions about which are necessary [Sidelle]
Can anything in science reveal the necessity of what it discovers? [Sidelle]
Because some entities overlap, reference must have analytic individuation principles [Sidelle]
Causal reference presupposes essentialism if it refers to modally extended entities [Sidelle]
We aren't clear about 'same stuff as this', so a principle of individuation is needed to identify it [Sidelle]
'Dthat' operates to make a singular term into a rigid term [Sidelle]
