This book investigates the logical and semantic complexities inherent in ascribing mental states through the use of intensional transitive verbs. Graeme Forbes, a scholar in the philosophy of language, utilizes a framework grounded in natural language semantics to analyze how verbs such as 'want', 'seek', 'imagine', and 'worship' function within propositional attitudes. He proposes a novel theory that reconciles the linguistic structure of these verbs with their psychological and aesthetic implications.

Experts in the philosophy of language recognize this work as a significant contribution to the study of intensionality and semantic theory. Readers frequently note the technical density of the prose, which requires a strong background in formal logic and linguistic analysis to fully grasp the author's arguments.
