Single Idea 15378

[filed under theme 4. Formal Logic / E. Nonclassical Logics / 9. Awareness Logic ]

Full Idea

Awareness logic enriched Hintikka's epistemic models with an awareness function, mapping each state to the set of formulas we are aware of at that state. This reflects some bound on the resources we can bring to bear.

Gist of Idea

Awareness logic adds the restriction of an awareness function to epistemic logic

The 7 ideas from 'Intensional Logic'

Classical logic is deliberately extensional, in order to model mathematics [Fitting]
λ-abstraction disambiguates the scope of modal operators [Fitting]
If terms change their designations in different states, they are functions from states to objects [Fitting]
Intensional logic adds a second type of quantification, over intensional objects, or individual concepts [Fitting]
Definite descriptions pick out different objects in different possible worlds [Fitting]
Awareness logic adds the restriction of an awareness function to epistemic logic [Fitting]
Justication logics make explicit the reasons for mathematical truth in proofs [Fitting]
