· More generally, possible worlds can be used to construct "intensions"
for subsentential expressions, which will combine compositionally to
determine the containing sentence's truth condition.
· The resulting view avoids both the problem of coextending but
nonsynonymous terms and the problem of non-truth-functional
connectives.
· The possible-worlds theory also deepens Frege's solution to the
Problem of Substitutivity.
· But the theory inherits a number of Davidson's original di fficulties
and incurs one or two more.
Questions
1 Evaluate Lewis' direct argument for the possible-worlds version of the
Truth-Condition Theory.
2 Discuss the possible-worlds theory further, pro, con, or both. (If you
do not already know some possible-worlds semantics, you will want to
do at least a bit of outside reading; I recommend Lewis (1970).)
3 Adjudicate objection 7 or objection 8.
