Philosophical Studies, 2012
This paper unfolds in four steps. First it rehearses the main ingredients of John Pollock's groundbreaking approach to defeasible reasons. Then it unpacks those ingredients to generate puzzling explanations for why, on his view, defeaters do their job. Then it uses that discussion to critique Pollock's approach to undercutting defeaters.

Reasons for Action and Defeasibility*
2012The main purpose of this essay is to answer a very general question that may be posed in the following terms: can reasons for action be defeasible? Any position regarding this issue will entirely depend on how the terms under consideration are understood.

Defeasible Reasoning about Electric Consumptions
2016 IEEE 30th International Conference on Advanced Information Networking and Applications (AINA), 2016Conflicting rules and rules with exceptions are very common in natural language specification to describe the behaviour of devices operating in a real-world context. This is common exactly because those specifications are processed by humans, and humans apply common sense and strategic reasoning about those rules.

Advanced Topics: Defeasible Reasoning
1990The principal novelty this book brings to probability theory is a sophisticated epistemology accommodating defeasible reasoning. It is this that makes the theory of nomic probability possible. Earlier theories lacked the conceptual framework of prima facie reasons and defeaters, and hence were unable to adequately formulate principles of probabilistic ...

Defeasible Reasoning and Representation
2017The Gettier Problem exhibits how our human cognitive fallibility of representation noted by Sellars and Quine always leaves open the possibility of completely justified beliefs being false. True justified belief, Gettier showed us, may result from the deduction of a justified false belief and thus fall short of knowledge.

Deontic Logic Viewed as Defeasible Reasoning
1997The notion of defeasibility in normative reasoning has been discussed by legal philosophers such as Gardner (1987), Hart (1948, 1958), and MacCormick (1974). For instance, MacCormick, in his 1974 article and also in an unpublished research note “Defeasibility in Law and Logic,” stated that an “institutional fact,” supporting the validity of a certain ...

The Reasoning View and Defeasible Practical Reasoning
Philosophy and Phenomenological Research, 2017According to the Reasoning View about normative reasons, facts about normative reasons for action can be understood in terms of facts about the norms of practical reasoning. I argue that this view is subject to an overlooked class of counterexamples, familiar from debates about Subjectivist theories of normative reasons.

Analysis of Defeasible Reasoning
2018This chapter describes implementation of abductive and modified conclusions by means of NTA. The algorithm and rules to form hypotheses for abductive conclusions are proposed. They can be applied not only to NTA objects expressing formulas of propositional calculus, but also to a more general case when attribute domains contain more than two values ...

Semantics for Pollock’s Defeasible Reasoning
1999Many researchers have proposed argumentation-based reasoning as a viable alternative to reasoning systems with a flat epistemological structure. Perhaps one of the longest standing approaches heis been in the Oscar project, led by John Pollock. Unfortunately, without a formal semaintics, it is often difficult to evaluate the various incarnations of ...
