This work investigates the mechanisms of intentionality and how language functions when attributing mental states to individuals. Richard Mark Sainsbury, a prominent philosopher of language and mind, utilizes a rigorous analytical framework to propose a new theory regarding the nature of attitudes such as thinking, hoping, and wanting. He addresses the persistent philosophical problem of how mental states can be directed toward objects, specifically focusing on the challenge of intentionality regarding non-existent entities.
