[email protected] ABSTRACT: This presentation seeks to understand informal logic as a set of methods for the logical evaluation of natural language arguments. Some of the methods identified are the fallacies method, deductivism, warrantism and argument schemes. A framework for comparing the adequacy of the methods is outlined consisting of the following categories: learner- and user-efficiency, subjective and objective reliability, and scope. Within this framework, it is also possible to compare informal and formal logic. KEYWORDS: logic, illative evaluation, conceptual standard, operational standard, methods, reliability, efficiency, scope 1. INTRODUCTION Imagine that you have received a grant to study the argumentation surrounding a topic of current interest, the arguments about whether there should be unrestricted building of energy-producing windmills, for example, or whether your country should be involved in an overseas war, or whether we should eat genetically modified foods.
