'This is an important contribution to our understanding of mind and of the nature of belief. Frankish explores, with care and imagination, the subtle ways in which science and our 'folk' image converge and diverge. Folk psychology, according to Frankish, has two distinct theoretical cores. Failure to make this distinction leads to confusion and cross talk. In this well-paced and readable treatment, Frankish offers a clear, constructive and original angle on some of the most persistent and perplexing problems in the field. Recommended reading for anyone interested in the philosophy and science of mind and belief.' Andy Clark, Indiana University
