Cover art for "A Logician’s Code of Conduct" by Patrick Girard
Jeff Dillon’s painting #101 "Cerro Torre" is featured on the cover of A Logician’s Code of Conduct: How You Can Use Logic to Make the World More Just by Patrick Girard, published by McGill-Queen’s University Press.
ABOUT THE BOOK
The logic we rely on every day to help us communicate and make decisions can also reinforce injustice. Logic is often treated as a neutral arena for reasoning, but that supposed neutrality can fail to include everyone on fair terms. When certain ways of thinking are dismissed as incoherent reasoning, logic itself can become a tool of exclusion, supporting patterns of oppression, silencing voices, and erasing people.
Drawing on lessons from feminist, queer, and post-colonial theory, A Logician’s Code of Conduct challenges us to listen more carefully to those who have been pushed to the margins of social and intellectual life, not just public voices, but people in our workplaces, communities, and families. Instead of demanding that people continually defend their deeply held beliefs, logic can be a flexible and revisable framework that adapts to multiple perspectives. Patrick Girard outlines a code of conduct to make logic more just: be transparent about assumptions, negotiate standards suited to each context, and recognize others as coherent reasoners. Logic, Girard argues, can both liberate and connect us, creating spaces of inquiry that are not only neutral but also equitable.
In clear, accessible prose and free of formal symbolism, A Logician’s Code of Conduct is a bold and original contribution to logic and social philosophy. Girard demonstrates that logic is not an abstract discipline reserved for philosophers, but a practical resource we all use every day and one we can learn to apply more fairly and effectively.
REVIEWS
“Writing in a highly readable, engaging style and drawing on his considerable knowledge of logic (including non-classical logics), Patrick Girard makes a compelling case for logical rehabilitation. His understanding of logic as a discipline that clarifies structures and patterns of thought and reasoning underscores his argument for developing deeper engagements with the coherence of people’s views, particularly when those views reflect differing social experiences and cultural backgrounds.” ~ Phyllis Rooney, Oakland University
“A Logician’s Code of Conduct is excellent, engaging, personal, and a joy to read. Girard provides a unique and sophisticated perspective that illuminates not only the potential limitations of logic but also its transformative and generative potential.” ~ Kate Phillips, University of Rochester
