 The idea that informal logic should be developed as a distinct field of inquiry was championed by Johnson and Blair at the University of Windsor. They published a popular textbook, Logical Self-Defense (1977); organized and hosted “The First International Symposium on Informal Logic” and edited the proceedings (Blair and Johnson, 1980); established the Informal Logic Newsletter (1978-1983); and ultimately turned the newsletter into the journal Informal Logic (subtitled “Reasoning and Argumentation in Theory and Practice”). In this and other ways, they established informal logic as a field for study, research and development. Their contributions (and those of colleagues at Windsor and in Ontario and Canada) is reflected in the notion that informal logic is a Canadian (or, more narrowly, Windsor) school of argument (see Puppo 2019).
