Abstract
The late Richard Paul was arguably the most well-known and influential person in the history of the critical thinking movement. This reflection on and tribute to his work focuses on Paul’s genius in applying his knowledge of important works in the history of philosophy to the development of a robust conception of critical thinking, one that has wide appeal, not only to philosophers, but to faculties across academe. I also discuss the debt so many of us who teach critical thinking owe to his amazing scholarly and organizational skills, e.g., the 36 years of the Conference on Critical Thinking and Educational Reform, his in-service work for hundreds of faculties, his distribution of over one million “Thinkers Guides,” and his successful efforts to make critical thinking the core concept in education.
