The externalist's demon

Lets say that two individuals are epistemic counterparts iff they hap pen to be in precisely the same (non-factive) mental states. If one has a veridical experience, her counterparts will undergo a subjectively indistinguishable conscious experience. If she remembers something, her counterparts will seem to recall the same event or fact. If she knows something to be true, her counterparts will believe it to be true. Coun terparts always find the same things intuitive. Any difference between those who know a great deal about the external world and their sys

Moore's paradox and epistemic norms

We shall evaluate two strategies for motivating the view that knowledge is the norm of belief. The first draws on observations concerning beliefs aim and the parallels between belief and assertion. The second appeals to observations concerning Moores Paradox. Neither of these strategies gives us good reason to accept the knowledge account. The considerations offered in support of this account motivate only the weaker account on which truth is the fundamental norm of belief.

Just Do It? When To Do What You Judge You Ought to Do

While it is generally believed that justification is a fallible guide to the truth, there might be interesting exceptions to this general rule. In recent work on bridge-principles, an increasing number of authors have argued that truths about what a subject ought to do are truths we stand in some privileged epistemic relation to and that our justified normative beliefs are beliefs that will not lead us astray. If these bridge-principles hold, it suggests that justification might play an interesting role in our normative theories. In turn, this might help us understand the value of justification, a value that’s notoriously difficult to understand if we think of justification as but a fallible means to a desired end. We will argue that these bridge-principles will be incredibly difficult to defend. While we do not think that normative facts necessarily stand in any interesting relationship to our justified beliefs about them, there might well be a way of defending the idea that our justified beliefs about what to do won’t lead us astray. In turn, this might help us understand the value of justification, but this way of thinking about justification and its value comes with costs few would be willing to pay.

Knowledge, Reasons, and Errors About Error Theory

According to moral error theorists, moral claims necessarily represent categorically or robustly normative facts. But since there are no such facts, moral thought and discourse are systematically mistaken. One widely discussed objection to the moral error theory is that it cannot be true because it leads to an epistemic error theory. We argue that this objection is mistaken. Objectors may be right that the epistemic error theory is untenable. We also agree with epistemic realists that our epistemological claims are not systematically in error. However, this is not because there are robustly normative facts, but rather because the truth of our epistemic claims doesn’t turn on whether there are such facts. Epistemic facts, we argue, are not robustly or categorically normative. Moral error theorists should therefore respond to the objection that their view does not commit them to the epistemic error theory.

Truth, knowledge, and the standard of proof in criminal law

Could it be right to convict and punish defendants using only statistical evidence? In this paper, I argue that it is not and explain why it would be wrong. This is difficult to do because there is a powerful argument for thinking that we should convict and punish defendants using statistical evidence. It looks as if the relevant cases are cases of decision under risk and it seems we know what we should do in such cases (i.e., maximize expected value). Given some standard assumptions about the values at stake, the case for convicting and punishing using statistical evidence seems solid. In trying to show where this argument goes wrong, I shall argue (against Lockeans, reliabilists, and others) that beliefs supported only by statistical evidence are epistemically defective and (against Enoch, Fisher, and Spectre) that these epistemic considerations should matter to the law. To solve the puzzle about the role of statistical evidence in the law, we need to revise some commonly held assumptions about epistemic value and defend the relevance of epistemology to this practical question.
