'Cognitive Ontology works out a detailed metaphysics of psychological kinds and demonstrates its fruitfulness through a series of lucidly argued empirical studies. Few works can match its combined scope and insight. It promises to substantially broaden the terrain on which debates over cognitive ontology are staged.' Daniel Weiskopf, Georgia State University

'Muhammad Ali Khalidi's book, Cognitive Ontology: Taxonomic Practices in the Mind-Brain Sciences, offers a compelling non-reductionist approach to understanding the furniture of the mind: the 'real kinds' of cognitive science. This book is a thoughtful and timely addition to current debates over the ontology of the mind-brain sciences.' Zoe Drayson, The Brains Blog

'The book beautifully illustrates and advocates for philosophy's role in mapping the landscape of the mind. As philosophers, we contribute to this work not only by defending the legitimacy of cognitive kinds, but by advising and possibly even guiding the process by which decisions are made as to which kinds to privilege and which to dismiss, which to lump and which to split. Khalidi has provided an innovative and comprehensive framework for identifying cognitive kinds.' Sarah Robins, Mind & Language
