“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.     

The Epistemic Status of Evolutionary Theory

The theory of evolution continues to be a bone of contention among certain groups of theistic believers. This paper aims to bring some light to the debate about it, by introducing a framework for epistemic appraisal which can provide a realistic and sober assessment of the epistemic credentials of the various parts of evolutionary theory. The upshot is a more nuanced epistemic appraisal of the theory of evolution, which shows that there are significant differences in epistemic standing between its various parts. Any serious conversation about the theory of evolution ought to reflect these facts.     

Supererogation Across Normative Domains

The phenomenon of moral supererogation—action that goes beyond what moral duty requires—is familiar. In this paper, I argue that the concept of supererogation is applicable beyond the moral domain. After an introductory section 1, I outline in section 2 what I take to be the structure of moral supererogation, explaining how it comes to be an authentic normative category. In section 3, I show that there are structurally similar phenomena in other normative domains—those of prudence, etiquette, and the epistemic—and give examples of acts of supererogation of each of these types.     

On Toleration,Charity, and Epistemic Fallibilism

In this paper I examine some presuppositions of toleration and pluralism and explore two models, viz., a deontological and a consequentialist model, respectively, which could support the view that rational agents should act in a tolerant way. Against the background which is offered by the first model, I give two arguments in favor of the view that people are better off and more rational if they act in a tolerant way. The first argument draws upon a principle of charity which is usually applied in philosophy of mind and philosophy of language, but which could, equally well, work with regard to foundational issues in ethics and philosophy of action. The second argument is built upon the epistemic principle of fallibilism and it is meant to show that acting in a tolerant way is the rational thing to do from this perspective.     

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.     

Shedding Dialectical Tiers: A Social-Epistemic View

Is there a duty to respond to objections in order to present a good argument? Ralph Johnson argues that there is such a duty, which he refers to as the “dialectical tier“ of an argument. I deny the (alleged) duty primarily on grounds that it would exert too great a demand on arguers, harming argumentation practices. The valuable aim of responding to objections, which Johnson 's dialectical tier is meant to satisfy, can be achieved in better ways, as argumentation is a social-epistemic activity.     

On the Theoretical Unification and Nature of Fallacies

I argue in a non-reductive sense for a plausible epistemic principle, which can (1) theoretically and instrumentally unify or systematize all fallacies, and (2) provide a justification for using such a principle for characterizing an erroneous argument as a fallacy. This plausible epistemic principle involves the idea of an error in the method of justification, which results in a failure to provide relevant evidence to satisfy certain standards of adequate proof. Thus, all fallacies are systematically disguised failures to provide substantive proof: a failure in the attempt to persuade rationally, as opposed to emotionally or rhetorically. I argue that the epistemic idea of begging the question is essential to this idea of a fallacy as an inadequate proof.     

Comments on Plantinga’s Argument of Transworld Identity

Plantinga’s conception of possible worlds is problematic in one sense: it relies on the prior idea of modality. His strategy for resolving the puzzle of transworld identity is significant in the metaphysical sense but fruitless in the epistemological sense because world-indexed properties cannot be used as effectively in epistemic practice as their counterparts, i.e., space- and time-indexed properties. His isolation of transworld identification from transworld identity is unconvincing. This paper argues that the intelligibility of modal discourse and reference is the essence of transworld identity. It is also proved that transworld identification is the epistemic ground of such intelligibility. Hence, the transworld identification problem is the epistemological foundation of the transworld identity problem, and there must be a comprehensive answer to the former.     

Iterated Belief Change and the Recovery Axiom

The axiom of recovery, while capturing a central intuition regarding belief change, has been the source of much controversy. We argue briefly against putative counterexamples to the axiom—while agreeing that some of their insight deserves to be preserved—and present additional recovery-like axioms in a framework that uses epistemic states, which encode preferences, as the object of revisions. This makes iterated revision possible and renders explicit the connection between iterated belief change and the axiom of recovery. We provide a representation theorem that connects the semantic conditions we impose on iterated revision and our additional syntactical properties. We show interesting similarities between our framework and that of Darwiche–Pearl (Artificial Intelligence 89:1–29 1997). In particular, we show that intuitions underlying the controversial (C2) postulate are captured by the recovery axiom and our recovery-like postulates (the latter can be seen as weakenings of (C2)). We present postulates for contraction, in the same spirit as the Darwiche–Pearl postulates for revision, and provide a theorem that connects our syntactic postulates with a set of semantic conditions. Lastly, we show a connection between the contraction postulates and a generalisation of the recovery axiom. Portions of this paper were originally presented at ECAI 2002.
