Matthew McGrath

When we're inquiring to find out whether p is true, knowing that we'll get better evidence in the future seems like a good reason to suspend judgment about p now. But, as Matt McGrath has recently argued, this natural thought is in deep tension with traditional accounts of justification. On traditional views of justification, which doxastic attitude you are justified in having now depends on your current evidence, not on what you might learn later. McGrath proposes to resolve this tension by distinguishing between different ways of having a neutral attitude. I argue that McGrath's account is unable to account for the full range of cases in which an agnostic attitude is warranted. We can remedy this by pairing his account with my theory of transitional and terminal attitudes, which claims that attitudes are justified in different ways depending on whether they are formed in intermediate stages of deliberation or as conclusions of deliberation. I compare my view with an alternative, more parsimonious one, according to which deliberation itself is a source of new evidence. I argue that this alternative proposal is faced with a dilemma: it either generates a vicious regress, or it fails to capture the relevant cases.

When should you engage with difficult arguments against your cherished controversial beliefs? The primary conclusion of this book is that your obligations to engage with counterarguments are more limited than is often thought. In some standard situations, you shouldn't engage with difficult counterarguments and, if you do, you shouldn't engage with them open-mindedly. This conclusion runs counter to aspects of the Millian political tradition and political liberalism, as well as what people working in informal logic tend to say about argumentation. Not all misleading arguments wear their flaws on their sleeve. Each step of a misleading argument might seem compelling and you might not be able to figure out what's wrong with it. Still, even if you can't figure out what's wrong with an argument, you can know that it's misleading. One way to know that an argument is misleading is, counterintuitively, to lack expertise in the methods and evidence-types employed by the argument. When you know that a counterargument is misleading, you shouldn't engage with it open-mindedly and sometimes shouldn't engage with it at all. You shouldn't engage open-mindedly because you shouldn't be willing to reduce your confidence in response to arguments you know are misleading. And you sometimes shouldn't engage closed-mindedly, because to do so can be manipulative or ineffective. In making this case, Jeremy Fantl discusses echo chambers and group polarization, the importance in academic writing of a sympathetic case for the opposition, the epistemology of disagreement, the account of open-mindedness, and invitations to problematic academic speakers.
