This volume contains 12 papers addressed to researchers and advanced students in informal logic and related fields, such as argumentation, formal logic, and communications. Among the issues discussed are attempts to rethink the nature of argument and of inference, the role of dialectical context, and the standards for evaluating inferences, and to shed light on the interfaces between informal logic and argumentation theory, rhetoric, formal logic and cognitive psychology.

In redefining logic, philosophers need to go back to the Aristotelian roots of the subject, to expand the boundaries of the subject to include informal logic and to give up false oppositions between informal and formal logic.

An argumentative passage that might appear to be an instance of denying the antecedent will generally admit of an alternative interpretation, one on which the conditional contained by the passage is a preface to the argument rather than a premise of it. On this interpretation. which generally is a more charitable one, the conditional plays a certain dialectical role and, in some cases, a rhetorical role as well. Assuming only a very weak principle of exigetical charity, I consider what it (...) would take to justify the less charitable interpretation. I then present evidence that those conditions are seldom met. Indeed, I was unable to find a single published argument that can justifiably be charged with denying the antecedent. (shrink)

From ethics to epistemology to metaphysics, it is common for philosophers to appeal to “intuitions” about cases to identify counterexamples to one view and to find support for another. It would be interesting to examine the evidential status of such intuitions, snap judgments, gut reactions, or whatever you want to call them, but in this paper I will not be talking about moral, epistemological, or metaphysical intuitions. I’ll be focusing on semantic ones. In fact, I’ll be focusing on semantic intuitions (...) about sentences, not individual words (although the contributions of individual words may ultimately be at issue in some of these cases), and on closely related intuitions about what is said in utterances of those sentences. Such intuitions play an important role in philosophy of language.. (shrink)
