Of Miracles and Evidential Probability: Hume’s “Abject Failure” Vindicated
This paper defends David Hume's "Of Miracles" from John Earman's (2000) Bayesian attack by showing that Earman misrepresents Hume's argument against believing in miracles and misunderstands Hume's epistemology of probable belief. It argues, moreover, that Hume's account of evidence is fundamentally non-mathematical and thus cannot be properly represented in a Bayesian framework. Hume's account of probability is show to be consistent with a long and laudable tradition of evidential reasoning going back to ancient Roman law

Petitio principii: the case for non-fallaciousness
This paper presents a case for the non-fallaciousness of petitio principii in the context where the only evidence which can confirm the conclusion of an argument has a content which is identical to the content of the conclusion. The more usual rhetorical and dialectical frameworks for the analysis off allacies are challenged for what I describe as their proscriptive stance. As an alternative to proscription, I recommend an analysis of the context in which petitio arguments occur. Such an analysis, I argue, suggests the relaxation of a priority condition described by Waiton (1985) and the relevance to the present case of Sorensen's (1991) analysis ofthe non-circularity of certain 'P, therefore, P' arguments
A Case-Based Reasoning Method for Locating Evidence During Digital Forensic Device Triage
The role of triage in digital forensics is disputed, with some practitioners questioning its reliability for identifying evidential data. Although successfully implemented in the field of medicine, triage has not established itself to the same degree in digital forensics. This article presents a novel approach to triage for digital forensics. Case-Based Reasoning Forensic Triager (CBR-FT) is a method for collecting and reusing past digital forensic investigation information in order to highlight likely evidential areas on a suspect operating system, thereby helping an investigator to decide where to search for evidence. The CBR-FT framework is discussed and the results of twenty test triage examinations are presented. CBR-FT has been shown to be a more effective method of triage when compared to a practitioner using a leading commercial application
Generalized Evidence Theory
Conflict management is still an open issue in the application of Dempster
Shafer evidence theory. A lot of works have been presented to address this
issue. In this paper, a new theory, called as generalized evidence theory
(GET), is proposed. Compared with existing methods, GET assumes that the
general situation is in open world due to the uncertainty and incomplete
knowledge. The conflicting evidence is handled under the framework of GET. It
is shown that the new theory can explain and deal with the conflicting evidence
in a more reasonable way.Comment: 39 pages, 5 figure
