Abstract

In this reflection piece, Ralph Johnson provides an account of the development of informal logic and how it intersected with the Critical Thinking Movement. Section I is an account of the origins of what Johnson calls the “Informal Logic Initiative.” Section II discusses how the Informal Logic Initiative connected with the Critical Thinking Movement at the Sonoma State University Conferences starting in 1981. Section III discusses the relationship between logic and critical thinking. Section IV describes “The Network Problem,” which emerged for Johnson in the mid-1980s – largely as a result of his experiences at critical thinking conferences, especially the Sonoma State conference. Section V expresses some concerns about the current status of critical thinking as an educational idea and about the Critical Thinking Movement.
