“Sayeh Meisami’s remarkable study brings two major Shīʿī thinkers into conversation with one another, highlighting their points of convergence and divergence on the central problem of the nature of knowledge and authority. There is no doubt that this book will propel the study of Islamic thought to new and unforeseen heights, demanding of the intellectual historian a vision which straddles the worlds of pre-modern and contemporary philosophy and politics.” (Mohammed Rustom, associate professor at Carleton University,Canada, and author of The Triumph of Mercy: Philosophy and Scripture in Mullā Ṣadrā) “Knowledge and Power in the Philosophies of Ḥamīd al-Dīn Kirmānī and Mullā Ṣadrā is a significant addition to the study of the discursive bond between philosophy and Shiʿism. The book probes with distinct ability into the relation between the narratives of Islamic epistemology/psychology and that of Shiʿi authority as displayed in the works of al-Kirmānī and Mullā Ṣadrā. Besides detailing other works on similar subjects with rigour, the author articulates her arguments with relevance, offering a welcomed and valuable volume.” (Maria De Cillis, Research Associate and Managing Editor for the Shii Heritage Series at the Institute of Ismaili Studies in London, UK)
