This comprehensive text covers all the standard topics of the contemporary logic course--informal logic, classical deductive logic, induction and scientific reasoning, including the logical fallacies, legal reasoning, and the practice of argument analysis. Exceptionally fine examples and exercises illustrate and reinforce important points throughout. The text is accompanied by a Study Guide for students and an Instructor's Manual.

Reviews the scope, nature, and applications of the philosophical discipline, focusing on methods for distinguishing between valid and fallacious arguments and inferences.

Charles S. Peirce argued that, besides deduction and induction, there is a third mode of inference which he called " hypothesis " or " abduction." He characterized abduction as reasoning " from effect to cause," and as " the operation of adopting an explanatory hypothesis." Peirce ' s ideas about abduction, which are related also to historically earlier accounts of heuristic reasoning, have been seen as providing a logic of scientific discovery. Alternatively, abduction is interpreted as giving reasons for pursuing (...) a hypothesis. Inference to the best explanation has also been regarded as an important mode of justification, both in everyday life, detective stories, and science. In particular, scientific realism has been defended by an abductive nomiracle argument, while the critics of realism have attempted to show that this appeal to abduction is question - begging, circular, or incoherent. This paper approaches these issues by distinguishing weaker and stronger forms of abduction, and by showing how these types of inferences can be given Peircean and Bayesian probabilistic reconstructions.

In this paper I want to cast doubt on the claim that there is a legitimate process of reasoning to the best explanation which can serve as an alternative to either straightforward inductive reasoning or a combination of inductive and deductive reasoning. I shall argue a) that paradigmatic cases of acceptable arguments to the best explanation must be considered enthymemes and b) that when the suppressed premises are made explicit we have all of the premises we need to present either (...) a straightforward inductive argument or an argument employing both induction and deduction.

Feminist philosophy seems to conflict with traditional philosophical methodology. For example, some uses of the concept of gender by feminist philosophers seem to commit the genetic fallacy. I argue that use of the concept of gender need not commit the genetic fallacy, but that the concept of gender is problematic on other grounds.
