 Fallacies remain a popular way to teach reasoning, as does argument analysis more generally. Both play central roles in the content of Canadian, US, and UK post-secondary education as part of the set of skills regularly taught under the name “critical thinking” in philosophy departments. Education allows cultures of reasoning to reinforce and reproduce themselves and these cultures affect the prospects for feminist transformation of the larger society. Educational institutions have authority and grant authority to systems of thought and to individuals and in this way critical thinking education provides opportunities for conformity or for social transformation, starting at the level of individual reasoning and interpersonal discourse. In many ways, the ideal and practice of critical thinking serves social progress but in other ways it needs reform.
