Single Idea 9174

[filed under theme 10. Modality / D. Knowledge of Modality / 3. A Posteriori Necessary ]

Full Idea

Although the statement that this table (if it exists at all) was not made of ice, is necessary, it certainly is not something that we know a priori.

Gist of Idea

It is necessary that this table is not made of ice, but we don't know it a priori

A Reaction

One of the key thoughts in modern philosophy. Kit Fine warns against treating it as a new and exciting toy, but it is a new and exciting toy. Scientific essentialism, which I so want to be true, is built on this proposal.


The 10 ideas with the same theme [knowing what has to be, by means of experience]:

Quine's indispensability argument said arguments for abstracta were a posteriori [Quine, by Yablo]
For Quine the only way to know a necessity is empirically [Quine, by Dancy,J]
Essentialists say natural laws are in a new category: necessary a posteriori [Ellis]
It is necessary that this table is not made of ice, but we don't know it a priori [Kripke]
Kripke has demonstrated that some necessary truths are only knowable a posteriori [Kripke, by Chalmers]
"'Hesperus' is 'Phosphorus'" is necessarily true, if it is true, but not known a priori [Kripke]
Theoretical identities are between rigid designators, and so are necessary a posteriori [Kripke]
How can you show the necessity of an a posteriori necessity, if it might turn out to be false? [Jackson]
Critics say there are just an a priori necessary part, and an a posteriori contingent part [Stalnaker]
The necessary a posteriori is statements either of identity or of essence [Sidelle]
