Description: Analogical reasoning plays a significant role in the evolution of scientific thought. Not only is analogy extensively used in the early stages of investigation to demonstrate the plausibility of hypotheses, but in some fields, such as archaeology and evolutionary biology, it may sometimes be the strongest possible form of theoretical confirmation. This widely used form of reasoning, however, has been subjected to only limited examination by philosophers of science; Mary Hesses Models and Analogies in Science is the most serious study. In the last two decades, researchers in AI have developed computational models of analogy. Because of the diversity of fields in which analogies are used, and because of its dependence on detailed contextual knowledge, finding a satisfactory model of analogical reasoning has proved elusive. In addition, relatively few philosophers have attempted to explain what justifies analogical reasoning.
In the first part of the course, after presenting some historical examples of analogical reasoning in science, we focus on the philosophical literature on this topic. We will then examine leading examples of computational theories of analogy. Rather than developing a logic of analogy, the objective here is to appreciate the central difficulties in formulating an account of analogical reasoning, and to understand possible directions in which a solution to those difficulties might lie.
The second portion of the course concentrates more generally on the topic of plausible reasoning. Using Judea Pearls book, Probabilistic Reasoning in Intelligent Systems, we study different models of plausible reasoning, including probabilistic systems and non-monotonic logic.
