This paper addresses a problem for theories of epistemic democracy. In a decision on a complex issue which can be decomposed
into several parts, a collective can use different voting procedures: Either its members vote on each sub-question and the
answers that gain majority support are used as premises for the conclusion on the main issue (premise based-procedure, pbp), or the vote is conducted on the main issue itself (conclusion-based procedure, cbp). The two procedures can lead to different results. We investigate which of these procedures is better as a truth-tracker,
assuming that there exists a true answer to be reached. On the basis of the Condorcet jury theorem, we show that the pbp is universally superior if the objective is to reach truth for the right reasons. If one instead is after truth for whatever
reasons, right or wrong, there will be cases in which the cbp is more reliable, even though, for the most part, the pbp still is to be preferred. 相似文献

Whether psychopathic offenders are practically rational has attracted philosophical attention. The problem is relevant in theoretical discussions in moral psychology and in discussions concerning the appropriate social response to the crimes of these individuals. We argue that classical and current experiments concerning the instrumental learning in psychopaths cannot directly support the conclusion that they have impaired instrumental rationality, construed as the ability to transfer motivation by means-ends reasoning. We claim that these experiments appear to show that psychopaths in certain circumstances are not aware of the relevant means for their ends. Moreover, we suggest how further empirical research could help to settle the issue. 相似文献

Within a formal epistemic model for simultaneous-move games, we present the following conditions: (1) belief in the opponents’ rationality (BOR), stating that a player believes that every opponent chooses an optimal strategy, (2) self-referential beliefs (SRB), stating that a player believes that his opponents hold correct beliefs about his own beliefs, (3) projective beliefs (PB), stating that i believes that j’s belief about k’s choice is the same as i’s belief about k’s choice, and (4) conditionally independent beliefs (CIB), stating that a player believes that opponents’ types choose their strategies independently. We show that, if a player
satisfies BOR, SRB and CIB, and believes that every opponent satisfies BOR, SRB, PB and CIB, then he will choose a Nash strategy
(that is, a strategy that is optimal in some Nash equilibrium). We thus provide a sufficient collection of one-person conditions
for Nash strategy choice. We also show that none of these seven conditions can be dropped. 相似文献

Whom I call ‘epistemic reductionists’ in this article are critics of the notion of ‘moral luck’ that maintain that all supposed
cases of moral luck are illusory; they are in fact cases of what I describe as a special form of epistemic luck, the only
difference lying in what we get to know about someone, rather than in what (s)he deserves in terms of praise or blame. I argue
that epistemic reductionists are mistaken. They implausibly separate judgements of character from judgements concerning acts,
and they assume a conception of character that is untenable both from a common sense perspective and with a view to findings
from social psychology. I use especially the example of Scobie, the protagonist of Graham Greene’s novel The Heart of the Matter, to show that moral luck is real—that there are cases of moral luck that cannot be reduced to epistemic luck. The reality
of moral luck, in this example at least, lies in its impact on character and personal and moral identity.

The fact that we ought to prefer what is comparatively more likely to be good, I argue, does, contrary to consequentialism,
not rest on any evaluative facts. It is, in this sense, a deontological requirement. As such it is the basis of our valuing
those things which are in accordance with it. We value acting (and believing) well, i.e. we value acting (and believing) as
we ought to act (and to believe). In this way, despite the fact that our interest in justification depends on our interest
in truth, we value believing with justification on non-instrumental grounds. A deontological understanding of justification,
thus, solves the Value of Knowledge Problem.

This paper argues that a priori justification is, in principle, compatible with naturalism—if the a priori is understood in
a way that is free of the inessential properties that, historically, have been associated with the concept. I argue that empirical
indefeasibility is essential to the primary notion of the a priori; however, the indefeasibility requirement should be interpreted
in such a way that we can be fallibilist about apriori-justified claims. This fallibilist notion of the a priori accords with
the naturalist’s commitment to scientific methodology in that it allows for apriori-justified claims to be sensitive to further
conceptual developments and the expansion of evidence. The fallibilist apriorist allows that an a priori claim is revisable
in only a purely epistemic sense. This modal claim is weaker than what is required for a revisability thesis to establish
empiricism, so fallibilist apriorism represents a distinct position.

Dynamic epistemic logic with branching temporal structures 总被引:1,自引:0,他引:1
van Bentham et al. (Merging frameworks for interaction: DEL and ETL, 2007) provides a framework for generating the models
of Epistemic Temporal Logic (ETL: Fagin et al., Reasoning about knowledge, 1995; Parikh and Ramanujam, Journal of Logic, Language, and Information, 2003)
from the models of Dynamic Epistemic Logic (DEL: Baltag et al., in: Gilboa (ed.) Tark 1998, 1998; Gerbrandy, Bisimulations on Planet Kripke, 1999). We consider the logic
TDEL on the merged semantic framework, and its extension with the labeled past-operator “P
ϵ” (“The event ϵ has happened before which. . .”). To axiomatize the extension, we introduce a method for transforming a given
model into a normal form in a suitable sense. These logics suggest further applications of DEL in the theory of agency, the theory of learning, etc. 相似文献
