Contextualism, Skepticism, and the Gettier Problem

The contextualist epistemological theories proposed by David Lewis and othersoffer a view of knowledge which awards a central role to the contexts ofknowledge attributions. Such contexts are held to determine how strong anepistemic position must be in order to count as knowledge. Lewis has suggestedthat contextualism so construed can be used both to ward off the skeptic and tosolve the Gettier problem. A person knows P, he says, just in case her evidenceeliminates every possibility that not-P, where the domain of `every' is determinedby the context. Lewis provides a list of rules that can tell us, for a given context,which not-P possibilities must be eliminated and which can properly be ignored.But his account entails, counterintuitively, that knowledge can truly be attributedeven to a person in a Gettier situation provided only that the attributor is ignorantof the fact that the person is gettiered. It has been criticized on those grounds byS. Cohen. In this paper I shall argue that most other forms of contextualism sufferthe same fate as Lewis's. The allies of contextualism haven't yet shown us whethercontextualism can succeed in maintaining a notion of ordinary knowledge whileresisting the absurdity that knowledge can be a matter of sheer good luck. At theend of the paper I shall suggest a possible solution to the problem by showing howCohen's line of criticism leads to a modified conception of what sort of justificationa belief must have to count as knowledge in ordinary contexts.

Two Notions of Circularity

Crispin Wright’s epistemic response to McKinsey’s paradox is to argue that introspective knowledge of the first premise fails to transmit across the semantic externalist entailment in the second premise to the conclusion that one has such untoward knowledge of the external world. This paper argues first that Stewart Cohen and Jonathan Vogel’s bootstrapping arguments suffer from a novel kind of epistemic circularity, which triggers failure of transmission but allows for the possibility of basic perceptual knowledge. It is then argued that McKinsey’s paradox falls out as a special case of this template for transmission failure. The circularity in play is semantic: the paradox illicitly imports semantically relevant properties of knowledge-individuating sources into the contents of the knowledge states that those sources individuate by instantiating those properties. Importantly, this diagnosis permits the possibility of basic introspective knowledge as propounded by Tyler Burge and other semantic externalists.     

Two Notions of Shame

On most accounts present in the literature, the complex experience of shame has the injury to self‐esteem as its main component. A rival view, originally propounded by St Augustine, relates shame to the structure of human agency, and more specifically, to the conflict between will and desire. A recent version of this view developed by David Velleman relates shame to the capacity of self‐presentation and the need for privacy. I examine two different interpretations of Velleman's theory and argue that neither suggests a credible alternative to the received view.     

Two Notions of Scientific Justification

Scientific claims can be assessed epistemically in either of two ways: according to scientific standards, or by means of philosophical arguments such as the no-miracle argument in favor of scientific realism. This paper investigates the basis of this duality of epistemic assessments. It is claimed that the duality rests on two different notions of epistemic justification that are well-known from the debate on internalism and externalism in general epistemology: a deontological and an alethic notion. By discussing the conditions for the scientific acceptability of empirical results, it is argued that intrascientific justification employs the deontological notion. Philosophical disputes such as those on scientific realism can by contrast be shown to rest on the alethic notion. The implications of these findings both for the nature of the respective epistemic projects and for their interrelation are explored.     

A critique to the significance of Gettier counter-examples

Usually, people think that Gettier counter-examples challenged the traditional tripartite definition of knowledge and fundamentally changed the characteristic of the contemporary epistemology. This paper argues that regard for Gettier counter-examples is exaggerated, because (i) the JTB definition is neither an important nor a comprehensive one that covers all knowledge. Moreover, the significance of Gettier counter-examples is limited. (ii) The source of Gettier counter-examples lies in one arbitrary judgment, two mix-ups, three false assumptions, and a misunderstanding about the JTB definition. __________ Translated from Fudan Xuebao 复旦学报 (Fudan Journal), 2004 (5)     

Consciousness and Hegel's Solution to the Problem of the Criterion

Traditional epistemological interpretations have portrayed Hegel as offering a coherentist solution to the problem of the criterion in the introduction to The Phenomenology of Spirit. In this paper, I criticize the coherentist interpretation and present an alternative reading that emphasizes the central role of conscious experience in Hegel's argument. In the first part of the paper, I show how the passages commonly used to support the coherentist interpretation ultimately fail to do so and argue that coherence by itself cannot be the lynchpin for an adequate solution to the problem of the criterion. In the second part, I then develop a novel interpretation of Hegel's argument by drawing attention to the fact that Hegel formulates both the problem of the criterion and his solution to it in terms of consciousness.     

Another Solution to the Problem of Theoretical Terms

In this paper, a solution to the problem of theoretical terms is developed that is based on Carnap’s doctrine of indirect interpretation of theoretical terms. This doctrine will be given a semantic, model-theoretic explanation that is not given by Carnap himself as he remains content with a syntactic explanation. From that semantic explanation, rules for the truth-value assignment to postulates, i.e. sentences that determine the meaning of theoretical terms, are derived. The logical status of postulates will be clarified thereby in such a way that the problem of theoretical terms disappears.

A Modest Solution to the Problem of Rule-following

A modest solution to the problem(s) of rule-following is defended against Kripkensteinian scepticism about meaning. Even though parts of it generalise to other concepts, the theory as a whole applies to response-dependent concepts only. It is argued that the finiteness problem is not nearly as pressing for such concepts as it may be for some other kinds of concepts. Furthermore, the modest theory uses a notion of justification as sensitivity to countervailing conditions in order to solve the justification problem. Finally, in order to solve the normativity problem, it relies on substantial specifications of normal conditions such as those that have been proposed by Crispin Wright and Mark Johnston, rather than on Philip Pettit's functionalist specification. This theory is modest in that it does not meet the demands of Kripke's sceptic in full. Arguments are provided as to why this is not needed.     

Causal tracking reliabilism and the Gettier problem

This paper argues that reliabilism can handle Gettier cases once it restricts knowledge producing reliable processes to those that involve a suitable causal link between the subject’s belief and the fact it references. Causal tracking reliabilism (as this version of reliabilism is called) also avoids the problems that refuted the causal theory of knowledge, along with problems besetting more contemporary theories (such as virtue reliabilism and the “safety” account of knowledge). Finally, causal tracking reliabilism allows for a response to Linda Zagzebski’s challenge that no theory of knowledge can both eliminate the possibility of Gettier cases while also allowing fully warranted but false beliefs.

A Paraconsistent Solution to the Problem of Moral Dilemmas

Abstract

Moral dilemmas - situations in which an agent has a moral requirement to do each of two acts but cannot do both - seem to suggest some kind of inconsistency. I argue that the inconsistency felt intuitively is actually a logical inconsistency, and then go on to show that we can neither deny the existence of moral dilemmas nor give up the deontic principles involved in the deduction of a contradiction, as both our moral judgements and the deontic principles depend on intuitions that form the basis of our morality. Rather than rejecting our intuitions and thus undermining morality, I suggest regarding moral dilemmas as situations in which a contradiction is not only false, but at the same time true. Finally, the view that moral dilemmas are an example of true contradictions - so-called dialetheias - leads to the application of paraconsistent logic to moral judgements.
