We think with objects—we conduct our lives surrounded by external devices that help us recall information, calculate, plan, design, make decisions, articulate ideas, and organize the chaos that fills our heads. Medieval scholars learned to think with their pages in a peculiar way: drawing hundreds of tree diagrams. Lines of Thought is the first book to investigate this prevalent but poorly studied notational habit, analyzing the practice from linguistic and cognitive perspectives and studying its application across theology, philosophy, law, and medicine. These diagrams not only allow a glimpse into the thinking practices of the past but also constitute a chapter in the history of how people learned to rely on external devices—from stone to parchment to slide rules to smartphones—for recording, storing, and processing information. Beautifully illustrated throughout with previously unstudied and unedited diagrams, Lines of Thought is a historical overview of an important cognitive habit, providing a new window into the world of medieval scholars and their patterns of thinking.

Building on historical and contemporary literature in anthropology and art theory, Lines That Connect treats pattern as a material form of thought that provokes connections between disparate things through processes of resemblance, memory, and transformation. Pattern is constantly in a state of motion as it traverses spatial and temporal divides and acts as an endless source for innovation through its inherent transformability. Graeme Were argues that it is the ideas carried by pattern’s relational capacity that allows Pacific islanders to express their links to land, genealogy, and resources in the most economic ways. In doing so, his book is a timely and unique contribution to the analysis of pattern and decorative art in the Pacific amid growing debates in anthropology and art history. This striking and original study brings together objects and photographs, historical literature and contemporary ethnographic case studies to explore pattern in its logical workings. It presents the first-ever analysis of the well-known patterned shell valuable called kapkap as revealed in New Ireland mortuary feasts. Innovative research in the study of Christianity and the Baha’i faithful in the region shows how pattern has been appropriated in new religious communities. Were argues that pattern is used in various guises in performances, church architecture, and funerary images to contrasting effect. He explores the conditions under which pattern facilitates a connecting of old and new ideas and how missionary processes are implicated in this flow. He then considers the mechanisms under which pattern is internalized, paying particular attention to its embeddedness in spatial and numerical thinking. Finally, he examines how pattern carries new materials and technologies, which in turn provide new resources for sustaining old beliefs. Drawing on a multitude of fields (anthropology; art history; Pacific, museum, and religious studies; education; ethnomathematics), Lines That Connect raises key questions about the capacity of pattern across the Pacific to bind and sustain ideas about place, body, and genealogy in the most logical of ways.

To live, every being must put out a line, and in life these lines tangle with one another. This book is a study of the life of lines. Following on from Tim Ingold's groundbreaking work Lines: A Brief History, it offers a wholly original series of meditations on life, ground, weather, walking, imagination and what it means to be human. In the first part, Ingold argues that a world of life is woven from knots, and not built from blocks as commonly thought. He shows how the principle of knotting underwrites both the way things join with one another, in walls, buildings and bodies, and the composition of the ground and the knowledge we find there. In the second part, Ingold argues that to study living lines, we must also study the weather. To complement a linealogy that asks what is common to walking, weaving, observing, singing, storytelling and writing, he develops a meteorology that seeks the common denominator of breath, time, mood, sound, memory, colour and the sky. This denominator is the atmosphere. In the third part, Ingold carries the line into the domain of human life. He shows that for life to continue, the things we do must be framed within the lives we undergo. In continually answering to one another, these lives enact a principle of correspondence that is fundamentally social. This compelling volume brings our thinking about the material world refreshingly back to life. While anchored in anthropology, the book ranges widely over an interdisciplinary terrain that includes philosophy, geography, sociology, art and architecture.

It is considerably easier to say that modern philosophy began with Descartes than it is to define the modernity and philosophy to which Descartes gave rise. In Lines of Thought, Claudia Brodsky Lacour describes the double origin of modern philosophy in Descartes's Discours de la méthode and Géométrie, works whose interrelation, she argues, reveals the specific nature of the modern in his thought. Her study examines the roles of discourse and writing in Cartesian method and intuition, and the significance of graphic architectonic form in the genealogy of modern philosophy. While Cartesianism has long served as a synonym for rationalism, the contents of Descartes's method and cogito have remained infamously resistant to rational analysis. Similarly, although modern phenomenological analyses descend from Descartes's notion of intuition, the "things" Cartesian intuitions represent bear no resemblance to phenomena. By returning to what Descartes calls the construction of his "foundation" in the Discours, Brodsky Lacour identifies the conceptual problems at the root of Descartes's literary and aesthetic theory as well as epistemology. If, for Descartes, linear extension and "I" are the only "things" we can know exist, the Cartesian subject of thought, she shows, derives first from the intersection of discourse and drawing, representation and matter. The crux of that intersection, Brodsky Lacour concludes, is and must be the cogito, Descartes's theoretical extension of thinking into material being. Describable in accordance with the Géométrie as a freely constructed line of thought, the cogito, she argues, extends historically to link philosophy with theories of discursive representation and graphic delineation after Descartes. In conclusion, Brodsky Lacour analyzes such a link in the writings of Claude Perrault, the architectural theorist whose reflections on beauty helped shape the seventeenth-century dispute between "the ancients and the moderns." Part of a growing body of literary and interdisciplinary considerations of philosophical texts, Lines of Thought will appeal to theorists and historians of literature, architecture, art, and philosophy, and those concerned with the origin and identity of the modern.
