It is sometimes claimed that we perceive people’s mental states in their expressive features. This paper clarifies the claim by contrasting two possible readings, depending on whether expression is conceived relationally or non-relationally. A crucial difference between both readings is that only a non-relational conception of expression ensures direct access to other minds. The paper offers an argument for a non-relational conception of expression, and therefore for the view that we directly perceive people’s mental states in their expressive features.

Mathematical platonism is the view that abstract mathematical objects exist. Ontological pluralism is the view that there are many modes of existence. This paper examines the prospects for...

I consider the rule of assertion according to which knowledge is sufficient for epistemically proper assertion. I examine a counterexample to this rule recently proposed by Jennifer Lackey. I present three responses to this counterexample. The first two, I argue, highlight some flaws in the counterexample. But the third response fails. The lessons I draw from examining these three responses allow me to propose two counterexamples to the sufficiency rule that are similar to Lackey’s but avoid its problems.

We have some justified beliefs about modal matters. A modal epistemology should explain what’s involved in our having that justification. Given that we’re realists about modality, how should we expect that explanation to go? In the first part of this essay, I suggest an answer to this question based on an analogy with games. Then, I outline a modal epistemology that fits with that answer. According to a theory-based epistemology of modality, you justifiably believe that p if you justifiably believe (...) a theory that says that p and you believe p on the basis of that theory. (shrink)
