Question

What is the issue presented in the problem regarding Quantified Modal Logic (QML) with varying domain?

a) The challenge of indexing language in models
b) The inconsistency of satisfaction clauses
c) Dealing with objects that may not exist in other accessible worlds
d) The validity of Carnap-Barcan formula

Answer 1

The issue presented in the problem is dealing with objects that may not exist in other accessible worlds.

Step-by-step explanation:

The issue presented in the problem regarding Quantified Modal Logic (QML) with varying domain is c) Dealing with objects that may not exist in other accessible worlds.

Quantified Modal Logic (QML) is a logical system that extends classical logic to deal with modalities, such as necessity and possibility, and quantifiers, which express the relationships between objects in a domain. With varying domain, the challenge arises when there are objects that may not exist in other accessible worlds, leading to difficulties in defining relations and quantifiers consistently.
