In The Reasonable Person: Traditional Logic for Modern Life, Mark Grannis makes the fundamentals of traditional logic comprehensible to students who have not previously studied logic or any other branch of philosophy. The book incorporates not only Grannis’s five years of daily experience in the classroom, but also his previous thirty years of professional experience and his characteristic focus on the practical relevance of the discipline. This makes the book appropriate not only for classroom use, but also for home study–especially in conjunction with the 2024 Teacher’s Supplement to The Reasonable Person.
