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 8 ideas from 'Identity and Necessity'

A 'rigid designator' designates the same object in all possible worlds [Kripke]
The function of names is simply to refer [Kripke]
We cannot say that Nixon might have been a different man from the one he actually was [Kripke]
It is necessary that this table is not made of ice, but we don't know it a priori [Kripke]
We may fix the reference of 'Cicero' by a description, but thereafter the name is rigid [Kripke]
Modal statements about this table never refer to counterparts; that confuses epistemology and metaphysics [Kripke]
Identity theorists must deny that pains can be imagined without brain states [Kripke]
Pain, unlike heat, is picked out by an essential property [Kripke]
