Rationality and Logic

About the Author

Robert Hanna is Professor of Philosophy at the University of Colorado at Boulder. He is the author of Kant and the Foundations of Analytical Philosophy.


“"A densely-argued and ambitious defense of a ‘broadly Kantian theory of human rationality and logic.’"
The Review of Metaphysics”—
“"An admirable and promising attempt to confront the question of the nature of logic and its relation to rationality in a substantive and open-minded manner, without excessive reliance on intuition or gut feeling, without hand waving, without begging questions, and in a creative and intellectually stimulating way. This book is highly recommended to philosophers, logicians, and cognitive psychologists."
Notre Dame Philosophical Reviews”—
“"Logic and Rationality is an important contribution to a debate that has been ignored for too long. Students and researchers who have thought that Frege’s and Husserl’s dismissal of logical psychologism was decisive should not ignore Hanna’s compelling argument for logical cognitivism. Hanna’s very impressive work deserves to be studied intently by those with an interest in the often criticized but largely overlooked relationship between logic and psychology."
Polish Journal of Philosophy”—


“"Hanna suggests that we human beings are rational in the sense that we have an innate grasp of the concepts needed for appraising the cogency of our own thinking. Starting from this idea, he steers an ingenious way between psychologism and Platonism, and argues persuasively for a neo-Kantian view of the nature of logic and our engagement with it. This stimulating and wide-ranging book will be of interest to philosophers of logic and also to cognitive psychologists."--Professor Jane Heal, University of Cambridge”
