Philosophy is buzzing again with interest in conceptions of thought and content more fine-grained than those of traditional intensional semantics. For anyone who wants to know what the buzz is all about, this superb new book by one of the foremost proponents of the hyperintensional movement is quite simply a must-read.
Hannes Leitgeb, Professor of Philosophy, LMU Munich
This wonderful book brings formal semantics and epistemology together, placing topic-sensitivity at the center of the logic of thought. Franz Berto takes the reader on a journey, starting from such a key idea and exploring it step by step to uncover new territory.
Sonja Smets, Professor of Logic and Epistemology, University of Amsterdam
Equipped with a simple notion of subject matter, Berto guides us through areas where logic normally fears to tread: imagination, intentionality, hypothesis-development, framing effects, epistemic fallibility, and awareness. A spectacularly good book. Did I mention omniscience, belief revision, and conditionals? Topic shines its light on them, too. You must absolutely read it.
Stephen Yablo, David W. Skinner Professor of Philosophy, Massachusetts Institute of Technology
The book presents a new framework for the logic of thought.

Prior to publication the book's content was vetted in numerous seminars, workshops, and conferences worldwide, so it may well be taken as a beacon for much of the future development of topic-sensitive logics of intentionality.

This is a fantastic book, which greatly advances our understanding of hyperintensional semantics...The semantics and its pros and cons, in particular also its current limitations, are all discussed with great clarity and intellectual honesty. The book is also a pleasure to read, filled with creative examples and written in an entirely unpre- tentious and highly accessible style. At the moment, I can think of no better starting point than Berto's book for anyone seriously interested in hyperintensional semantics.
Igor Douven, Mind
We find Topics of Thought to be an immensely valuable book full of original ideas and insights. We have learned a great deal from engaging with it, and we warmly recommend it to anyone who has interests in hyperintensionality, topicality and the logic of propositional attitudes such as knowledge, belief and imagination.
JC Bjerring and Mattias Skipper, Analysis
Topics of Thought is a mighty ambitious book and a thought-provoking (cringy pun intended) piece of philosophy.
Derek Lam, The Junkyard of the Mind
Topics of Thought is a wide-ranging and informative read, exploring with thoroughness and technical sophistication the logic of states of thought such as belief, knowledge, supposition, imagination, and so on.
