John Horty is Professor of Philosophy at the University of Maryland. He is the author of three previous books as well as papers on a variety of topics in logic, philosophy, artificial intelligence, and law. His most recent book is Reasons as Defaults (2012).
'This book is both clever and insightful, with several powerful and illuminating results and advances both conceptual and technical. It's deeply informed by a leading understanding of existing work in legal theory as well as in logic and artificial intelligence – a really impressive intellectual and scholarly accomplishment as well as an achievement in logic and philosophy. It should be required reading for anyone with an interest in legal reasoning or jurisprudence.' Mark Schroeder, University of Southern California
