"This is an excellent book. It offers a clear and concise overview of dynamic preference logic and logics that can reason about both beliefs and preferences. Fenrong has managed to provide an accessible and comprehensive overview of recent work in this area, including very interesting connections with deontic logic and game theory. I highly recommend this book for anyone interested in using logical models to reason about rational agents." Eric Pacuit, Tilburg Center for Logic and Philosophy of Science, The Netherlands "Reasoning about Preference Dynamics is an innovative and unusually well-written account of human preferences and how they change. It is a must for anyone interested in the dynamics of preferences." Sven Ove Hansson, KTH Royal Institute of Technology, Sweden "This nice book presents a survey of preference logics and preference dynamics, very much state-of-the-art, and Fenrong Liu is extremely well-informed about the relevant literature. She has a remarkable talent on how to restrict herself to the essentials, in order to convey the message and produce something very readable." Hans van Ditmarsch, University of Sevilla, Spain
