Two Interpretations of the Ramsey Test
According to the Ramsey Test, a person should accept a conditional to the
extent that she would accept the consequent on the supposition that the
antecedent holds. There are two attractive ways of interpreting the Ramsey
test: Adams’ Thesis, which states that the probability of a conditional is
the conditional probability of the consequent given the antecedent, and
Stalnaker semantics, which states that a conditional is true at a world w
just in case its consequent is true at all closest antecedent worlds to w.
Unfortunately, a well-known class of triviality theorems shows that when
the two interpretations of the Ramsey test are combined, they entail
seemingly absurd triviality results.
Stefan Kaufmann has proposed (for reasons largely independent of the
trivial- ity theorems) a revised version of Adams’ Thesis, which I call
Kaufmann’s Thesis. I prove that combining Kaufmann’s Thesis with Stalnaker
semantics leads “local triviality” results, which seem just as absurd as
the original triviality results. Luckily, Stalnaker semantics can be
revised too: in particular, it can be replaced with a generalized imaging
semantics. I argue that combining Kaufmann’s Thesis with generalized
imaging semantics provides a way of defanging the local triviality results,
not by undercutting the arguments for them, but by explaining why they are
not as philosophically problematic as they seem.
