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.

How can we think about maths, despite the immateriality of numbers, sets, and other mathematical entities? How are we able to think about what might have happened if history had taken a different turn? Questions like these turn up in nearly every part of cognitive science and are central to our human position of having limited knowledge of what is true.

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.

Jason Stanley presents a startling and provocative claim about knowledge: that whether or not someone knows a proposition at a given time is in part determined by his or her practical interests, i.e. by how much is at stake for that person at that time. So whether a true belief is knowledge is not merely a matter of supporting beliefs or reliability; in the case of knowledge, practical rationality and theoretical rationality are intertwined. Stanley defends this thesis against alternative accounts of the phenomena that motivate it, such as the claim that knowledge attributions are linguistically context-sensitive (contextualism about knowledge attributions), and the claim that the truth of a knowledge claim is somehow relative to the person making the claim (relativism about knowledge). In the course of his argument Stanley introduces readers to a number of strategies for resolving philosophical paradox, making the book essential not just for specialists in epistemology but for all philosophers interested in philosophical methodology. Since a number of his strategies appeal to linguistic evidence, it will be of great interest to linguists as well.

You don't have to be a genius to sound like one. Here's a collection of the most profound and provocative wit and wisdom in the English language in two lines or less. Edited by entrepreneur John M. Shanahan, who created the wildly successful Hooked on Phonics program, this wonderful book presents the best that has been thought and said on every imaginable topic. Classified by such themes as "Truth, Lies, and Deception," "Men, Women, and Relationships," and "Passions, Virtues, and Vices," these quotes contain timeless messages for all humankind. Oscar Wilde: "A man who marries his mistress leaves a vacancy in that position." Charles de Gaulle: "The cemetery is filled with indispensable men." Abraham Lincoln: "Nearly all men can stand adversity, but if you want to test a man's character, give him power." Sophocles: "Men of ill judgment oft ignore the good that lies within their hands, till they have lost it." Perfect for anyone who has ever been left speechless, this book will make you as glib as Oscar Wilde, as profound as Winston Churchill, and as wise as Aesop. Inspirational, entertaining, and thought-provoking, this is one collection that no library or bookshelf should be without.

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.
