    <description><![CDATA[There's a lively literature on how graded beliefs (credences) relate
to ungraded beliefs. Some hold that ungraded beliefs are reducible to
credences, others that credences are reducible to ungraded beliefs; yet
others hold that both are real and irreducible to one another. I find
this debate confusing. By which of course I mean: confused. I'll try to
explain why. I'll also comment on one particular proposal, that
credences are beliefs about probability; an interestingly new version of
this ha...]]></description>

    <title>Neg-raising through question-raising?</title>

    <description><![CDATA["Neg-raising" occurs when a negation that appears to have wide scope
(over some operator) is interpreted as having narrow scope. For example,
(1) conveys not only the absence of a belief that pizza is available (as
one might expect), but also the presence of a belief that pizza is
unavailable.
(1)I don't think there's any pizza.
There is a large literature on this phenomenon, with many competing
explanations. Foolishly, I've tried to contribute to this literature
with a new proposal.

    <description><![CDATA[Gerritsen
2023 raises a good worry about revolutionary moral fictionalism,
as advocated in Joyce
2001.
The (revolutionary moral) fictionalist says that our naive moral
practice rests on the mistaken assumption that there are
mind-independent moral facts. There are no such facts. But this doesn't
mean that we should stop caring about morality. It is in our personal
interest, according to the fictionalist, to adopt a fiction of morality
and continue talking and acting much like before.

    <title>Logical omniscience: beyond fragmentation and impossible worlds</title>

    <description><![CDATA[Standard Bayesianism assumes that agents are "logically omniscient":
they assign credence 1 to all necessary truths. This seems wrong.
But we need to be clear about the data (as Stalnaker has emphasized,
for example in 1991 and 1999). It's
not a datum that we don't give credence 1 to all necessary truths.
"Credence" is a theoretical term. The data that cast doubt on logical
omniscience are things like this:

I utter "I don't know the 12th digit of pi".
I utter "I'm more confident that the 12t...]]></description>

    <description><![CDATA[Imagine a community of people who pass encrypted messages to one
another, without knowing what they mean. Agent X has encrypted a message
and handed it to messenger A, who passes it to messenger B, who passes
it to agent Y, who has the codebook to decrypt the message. When A
utters the message to B, she has no idea what it says; neither does
B.
Intuitively, the meaning or content of A's
utterance is the content of the decrypted message. That's why A and B
don't know what the utterance means.
