Single Idea 9385

[filed under theme 10. Modality / D. Knowledge of Modality / 2. A Priori Contingent ]

Full Idea

If a speaker introduced a designator into a language by a ceremony, then in virtue of his very linguistic act, he would be in a position to say 'I know that Fa', but nevertheless 'Fa' would be a contingent truth (provided F is not an essential property).

Gist of Idea

The very act of designating of an object with properties gives knowledge of a contingent truth

Source

Saul A. Kripke (Naming and Necessity preface [1980], p.14)

Book Ref

Kripke,Saul: 'Naming and Necessity' [Blackwell 1980], p.14


A Reaction

If someone else does the designation, I seem to have contingent knowledge that the ceremony has taken place. You needn't experience the object, but you must experience the ceremony, even if you perform it.

Instead of talking about possible worlds, we can always say "It is possible that.." [Kripke]
Probability with dice uses possible worlds, abstractions which fictionally simplify things [Kripke]
Possible worlds allowed the application of set-theoretic models to modal logic [Kripke]
I don't think possible worlds reductively reveal the natures of modal operators etc. [Kripke]
