The main purpose of this book is to offer a comprehensive historical analysis of the discussions on a crucial problem for the Medieval theory of knowledge: the formal mediation of sensible reality in intellectual knowledge.

In Perception and the Internal Senses Juhana Toivanen offers a philosophical reconstruction of Peter of John Olivi’s (ca. 1248-98) conception of the cognitive psychology of the sensitive or animal soul.

Modern thought is characterized by a dichotomy of meaningful culture and unmeaning nature. Signs in the Dust uses medieval semiotics to develop a new theory of nature and culture that resists this familiar picture of things. Through readings of Thomas Aquinas, Nicholas of Cusa, and John Poinsot (John of St. Thomas), it offers a semiotic analysis of human culture in both its anthropological breadth as an enterprise of creaturely sign-making, and its theological height as a finite participation in the Trinity, which can be understood as an absolute 'cultural nature'. Signs in the Dust then extends this account of human culture backwards into the natural depth of biological and physical nature. It puts the biosemiotics of its medieval sources, along with Félix Ravaisson's philosophy of habit, into dialogue with the Extended Evolutionary Synthesis that is emerging in contemporary biology, to show how all living things participate in semiosis, so that that a cultural dimension is present through the whole order of nature and the whole of natural history. It also retrieves Aquinas' doctrine of intentions in the medium to show how signification can be attributed in a diminished way to even inanimate nature, with the ontological implication that being as such should be reconceived in semiotic terms. The phenomena of human culture are therefore to be understood not as breaks with a meaningless nature, but instead as heightenings and deepenings of natural movements of meaning that long precede and far exceed us. Against the modern divorce of nature and culture, Signs in the Dust argues that culture is natural and nature is cultural, through and through.

Five hundred years before “Jabberwocky” and Tender Buttons, writers were already preoccupied with the question of nonsense. But even as the prevalence in medieval texts of gibberish, babble, birdsong, and allusions to bare voice has come into view in recent years, an impression persists that these phenomena are exceptions that prove the rule of the period’s theologically motivated commitment to the kernel of meaning over and against the shell of the mere letter. This book shows that, to the contrary, the foundational object of study of medieval linguistic thought was vox non-significativa, the utterance insofar as it means nothing whatsoever, and that this fact was not lost on medieval writers of various kinds. In a series of close and unorthodox readings of works by Priscian, Boethius, Augustine, Walter Burley, Geoffrey Chaucer, and the anonymous authors of the Cloud of Unknowing and St. Erkenwald, it inquires into the way that a number of fourteenth-century writers recognized possibilities inherent in the accounts of language transmitted to them from antiquity and transformed those accounts into new ideas, forms, and practices of non-signification. Retrieving a premodern hermeneutics of obscurity in order to provide materials for an archeology of the category of the literary, Medieval Nonsense shows how these medieval linguistic textbooks, mystical treatises, and poems were engineered in such a way as to arrest the faculty of interpretation and force it to focus on the extinguishing of sense that occurs in the encounter with language itself.

Disagreement is inevitable, particularly in our current context, marked by the close coexistence of conflicting values and perspectives in politics, religion, and ethics. How can we deal with disagreement ethically and constructively in our pluralistic world? In Disagreeing Virtuously Olli-Pekka Vainio presents a valuable interdisciplinary approach to that question, drawing on insights from intellectual history, the cognitive sciences, philosophy of religion, and virtue theory. After mapping the current discussion on disagreement among various disciplines, Vainio offers fresh ways to understand the complicated nature of human disagreement and recommends ways to manage our interpersonal and intercommunal conflicts in ethically sustainable ways.

This study examines Thomas Aquinas’s contribution to the systematic field of animal philosophy. It applies various models from the current philosophical debate (especially from that concerning the mind of animals) as interpretative aids to tap the potential of the Thomistic approach. Thomas draws a clear line of demarcation between animals and human beings (= anthropological difference). However, he also considers it important to work out the similarities between humans and animals, insofar as they are both so-called animalia, i.e., living beings possessing senses (= animal conformance). His philosophical deliberations concerning animals have a methodological function as well, namely to highlight the distinct capacities of human beings. Thus, for Thomas, the reflection on animals is a key instrument in dealing with anthropological questions.

Winner of the 2022 Charles Rufus Morey Award from the College Art Association Guided by Aristotelian theories, medieval philosophers believed that nature abhors a vacuum. Medieval art, according to modern scholars, abhors the same. The notion of horror vacui—the fear of empty space—is thus often construed as a definitive feature of Gothic material culture. In The Absent Image, Elina Gertsman argues that Gothic art, in its attempts to grapple with the unrepresentability of the invisible, actively engages emptiness, voids, gaps, holes, and erasures. Exploring complex conversations among medieval philosophy, physics, mathematics, piety, and image-making, Gertsman considers the concept of nothingness in concert with the imaginary, revealing profoundly inventive approaches to emptiness in late medieval visual culture, from ingenious images of the world’s creation ex nihilo to figurations of absence as a replacement for the invisible forces of conception and death. Innovative and challenging, this book will find its primary audience with students and scholars of art, religion, physics, philosophy, and mathematics. It will be particularly welcomed by those interested in phenomenological and cross-disciplinary approaches to the visual culture of the later Middle Ages.
