"Dignaga's Investigation of the Percept" is a scholarly analysis that delves into the seminal work of Dignaga, an influential Indian Buddhist philosopher and logician. The book provides a detailed examination of Dignaga's theories on perception and epistemology, exploring his arguments that perception is a non-conceptual, direct form of cognition, distinct from inferential cognitive processes. Through a comprehensive study, the text not only elucidates Dignaga's philosophical contributions but also discusses their implications and the subsequent debates they sparked in classical Indian philosophy, offering insights into the broader discourse on the nature of knowledge and reality in Buddhist thought.
