EPISTEMIC MALEVOLENCE

Abstract: Against the background of a great deal of structural symmetry between intellectual and moral virtue and vice, it is a surprising fact that what is arguably the central or paradigm moral vice—that is, moral malevolence or malevolence proper—has no obvious or well-known counterpart among the intellectual vices. The notion of "epistemic malevolence" makes no appearance on any standard list of intellectual vices; nor is it central to our ordinary ways of thinking about intellectual vice. In this essay, I argue that there is such a thing as epistemic malevolence and offer an account of its basic character and structure. Doing so requires a good deal of attention to malevolence simpliciter . In the final section of the essay, I offer an explanation of our relative unfamiliarity with this trait.     

A strategy for assessing closure

This paper looks at an argument strategy for assessing the epistemic closure principle. This is the principle that says knowledge is closed under known entailment; or (roughly) if S knows p and S knows that p entails q, then S knows that q. The strategy in question looks to the individual conditions on knowledge to see if they are closed. According to one conjecture, if all the individual conditions are closed, then so too is knowledge. I give a deductive argument for this conjecture. According to a second conjecture, if one (or more) condition is not closed, then neither is knowledge. I give an inductive argument for this conjecture. In sum, I defend the strategy by defending the claim that knowledge is closed if, and only if, all the conditions on knowledge are closed. After making my case, I look at what this means for the debate over whether knowledge is closed.     

Constructive Empiricism and the Vices of Voluntarism

Abstract

Constructive empiricism – as formulated by Bas van Fraassen – makes no epistemological claims about the nature of science. Rather, it is a view about the aim of science, to be situated within van Fraassen’s broader voluntarist epistemology. Yet while this epistemically minimalist framework may have various advantages in defending the epistemic relevance of constructive empiricism, I show how it also has various disadvantages in maintaining its internal coherence.     

A Sequent Formulation of Conditional Logic Based on Belief Change Operations

Peter Gärdenfors has developed a semantics for conditional logic, based on the operations of expansion and revision applied to states of information. The account amounts to a formalisation of the Ramsey test for conditionals. A conditional A > B is declared accepted in a state of information K if B is accepted in the state of information which is the result of revising K with respect to A. While Gärdenfors's account takes the truth-functional part of the logic as given, the present paper proposes a semantics entirely based on epistemic states and operations on these states. The semantics is accompanied by a syntactic treatment of conditional logic which is formally similar to Gentzen's sequent formulation of natural deduction rules. Three of David Lewis's systems of conditional logic are represented. The formulations are attractive by virtue of their transparency and simplicity.     

The Brier Rule Is not a Good Measure of Epistemic Utility (and Other Useful Facts about Epistemic Betterness)

Measures of epistemic utility are used by formal epistemologists to make determinations of epistemic betterness among cognitive states. The Brier rule is the most popular choice (by far) among formal epistemologists for such a measure. In this paper, however, we show that the Brier rule is sometimes seriously wrong about whether one cognitive state is epistemically better than another. In particular, there are cases where an agent gets evidence that definitively eliminates a false hypothesis (and the probabilities assigned to the other hypotheses stay in the same ratios), but where the Brier rule says that things have become epistemically worse. Along the way to this ‘elimination experiment’ counter-example to the Brier rule as a measure of epistemic utility, we identify several useful monotonicity principles for epistemic betterness. We also reply to several potential objections to this counter-example.     

Defaults in update semantics

The aim of this paper is twofold: (i) to introduce the framework of update semantics and to explain what kind of semantic phenomena may successfully be analysed in it: (ii) to give a detailed analysis of one such phenomenon: default reasoning.     

Severe Withdrawal (and Recovery)

The problem of how to remove information from an agent's stock of beliefs is of paramount concern in the belief change literature. An inquiring agent may remove beliefs for a variety of reasons: a belief may be called into doubt or the agent may simply wish to entertain other possibilities. In the prominent AGM framework for belief change, upon which the work here is based, one of the three central operations, contraction, addresses this concern (the other two deal with the incorporation of new information). Makinson has generalised this work by introducing the notion of a withdrawal operation. Underlying the account proffered by AGM is the idea of rational belief change. A belief change operation should be guided by certain principles or integrity constraints in order to characterise change by a rational agent. One of the most noted principles within the context of AGM is the Principle of Informational Economy. However, adoption of this principle in its purest form has been rejected by AGM leading to a more relaxed interpretation. In this paper, we argue that this weakening of the Principle of Informational Economy suggests that it is only one of a number of principles which should be taken into account. Furthermore, this weakening points toward a Principle of Indifference. This motivates the introduction of a belief removal operation that we call severe withdrawal. We provide rationality postulates for severe withdrawal and explore its relationship with AGM contraction. Moreover, we furnish possible worlds and epistemic entrenchment semantics for severe withdrawals.     

The Image of God of Neurotheology: Reflections of Culturally Based Religious Commitments or Evolutionarily Based Neuroscientific Theories?

In Augustinian fashion, James B. Ashbrook and Carol Rausch Albright develop a neurotheology that finds evolutionarily based correlations between the functions of the human mind-brain and the roles God plays in human life. I argue that their assumptions of anthropomorphism , that the human mind-brain must conceptualize its environment in human terms, and realism , that anthropomorphism is correct, are evolutionarily unlikely. I conclude that the image of God ( imago dei ) the authors find reflected in the human mind-brain appears to derive from their Christian religious commitments rather than from evolutionary theory.     

Every Finitely Reducible Logic has the Finite Model Property with Respect to the Class of ♦-Formulae

In this paper a unified framework for dealing with a broad family of propositional multimodal logics is developed. The key tools for presentation of the logics are the notions of closure relation operation and monotonous relation operation. The two classes of logics: FiRe-logics (finitely reducible logics) and LaFiRe-logics (FiRe-logics with local agreement of accessibility relations) are introduced within the proposed framework. Further classes of logics can be handled indirectly by means of suitable translations. It is shown that the logics from these classes have the finite model property with respect to the class of -formulae, i.e. each -formula has a -model iff it has a finite -model. Roughly speaking, a -formula is logically equivalent to a formula in negative normal form without occurrences of modal operators with necessity force. In the proof we introduce a substantial modification of Claudio Cerrato's filtration technique that has been originally designed for graded modal logics. The main core of the proof consists in building adequate restrictions of models while preserving the semantics of the operators used to build terms indexing the modal operators.     

“THINGS COUNTER,ORIGINAL, SPARE,STRANGE”: DEVELOPING A POSTFOUNDATIONAL TRANSVERSAL MODEL FOR SCIENCE/RELIGION DIALOGUE

This second of three articles outlining the development and practice of a different approach to neurotheology discusses the construction of a suitable methodology for the project based on the work of J. Wentzel van Huyssteen. It explores the origin and contours of his concept of postfoundational rationality, its potential as a locus for epistemological parity between science and religion and the distinctive and unique transversal space model for interdisciplinary dialogue which he builds on these. It then proposes a further development of the model which has the potential to produce a very different type of additional and original dialogical outcome. While such “transversal” outputs may initially seem counter and strange they not only flow naturally from the models’ own inherent dynamics but also open up the possibility of a distinctively different form of neurotheology.
