In this volume Paul Guyer collects six of his seminal essays on philosophy and architecture, including a previously unpublished essay on Kant and Mies, and analyzing views about architecture in other philosophers and writers, including Laugier, Schopenhauer, Ruskin, and Susanne Langer. Guyer describes the gradual broadening of the Vitruvian conception of architectural value, and argues for a pluralism of values in architecture as he argued for pluralism in aesthetics in general in his monumental History of Modern Aesthetics (2014). Among his many other books are Reason and Experience in Mendelssohn and Kant (2020), Kant’s Impact on Moral Philosophy (2024), and, of special relevance to readers of this volume, A Philosopher Looks at Architecture (2021). Emeritus Professor of humanities and philosophy at Brown University, Guyer is a Member of the American Philosophical Society, a Fellow of the American Academy of Arts and Sciences, and winner of the 2024 International Kant Prize.
