The period between the fifteenth and the middle of the seventeenth centuries saw a great many changes and innovations in scientific thinking. These were communicated to various publics in diverse ways; not only through discursive prose and formal notations, but also in the form of instruments and images accompanying texts. The collected essays of this volume examine the modes of transmission of this knowledge in a variety of contexts. The schematic representation of instruments is examined in the case of the 'navicula' (a versatile version of a sundial) and the 'squadro' (a surveying instrument); the new forms of illustration of plants and the human body are investigated through the work of Fuchs and Vesalius; theories of optics and of matter are discussed in relation to the illustrations which accompany the texts of Ausonio and Descartes. The different diagrammatic strategies adopted to explain the complex medical theory of the latitude of health are charted through the work of medieval and sixteenth-century physicians; Kepler's use of illustration in his handbook of cosmology is placed in the context of book production and Copernican propaganda. The conception of astronomical instruments as either calculating devices or as cosmological models is examined in the case of Tycho Brahe and others. A study is devoted to the multiple functions of frontispieces and to the various readerships for which they were conceived. The papers in the volume are all based on new research, and they constitute together a coherent and convergent set of case studies which demonstrate the vitality and inventiveness of early modern natural philosophers, and their awareness of the media available to them for transmitting knowledge.

This book examines the relations and structures which enable and inhibit the sharing of knowledge within and across epistemic communities.

Our knowledge of the world comes from various sources. But it is sometimes said that testimony, unlike other sources, transmits knowledge from one person to another. In this book, Stephen Wright investigates what the transmission of knowledge involves and the role that it should play in our theorising about testimony as a source of knowledge. He argues that the transmission of knowledge should be understood in terms of the more fundamental concept of the transmission of epistemic grounds, and that the claim that testimony transmits knowledge is not only defensible in its own right, but indispensable to an adequate theory of testimony. This makes testimony unlike other epistemic sources.

This study reexamines the invention of the emblem book and discusses the novel textual and pictorial means that applied to the task of transmitting knowledge. It offers a fresh analysis of Alciato’s Emblematum liber, focusing on his poetics of the emblem, and on how he actually construed emblems. It demonstrates that the “father of emblematics” had vernacular forebears, most importantly Johann von Schwarzenberg who composed two illustrated emblem books between 1510 and 1520. The study sheds light on the early development of the Latin emblem book 1531–1610, with special emphasis on the invention of the emblematic commentary, on natural history, and on advanced methods of conveying emblematic knowledge, from Junius to Vaenius.

Testimony is an invaluable source of knowledge. We rely on the reports of those around us for everything from the ingredients in our food and medicine to the identity of our family members. Recent years have seen an explosion of interest in the epistemology of testimony. Despite the multitude of views offered, a single thesis is nearly universally accepted: testimonial knowledge is acquired through the process of transmission from speaker to hearer. In this book, Jennifer Lackey shows that this thesis is false and, hence, that the literature on testimony has been shaped at its core by a view that is fundamentally misguided. She then defends a detailed alternative to this conception of testimony: whereas the views currently dominant focus on the epistemic status of what speakers believe, Lackey advances a theory that instead centers on what speakers say. The upshot is that, strictly speaking, we do not learn from one another's beliefs - we learn from one another's words. Once this shift in focus is in place, Lackey goes on to argue that, though positive reasons are necessary for testimonial knowledge, testimony itself is an irreducible epistemic source. This leads to the development of a theory that gives proper credence to testimony's epistemologically dual nature: both the speaker and the hearer must make a positive epistemic contribution to testimonial knowledge. The resulting view not only reveals that testimony has the capacity to generate knowledge, but it also gives appropriate weight to our nature as both socially indebted and individually rational creatures. The approach found in this book will, then, represent a radical departure from the views currently dominating the epistemology of testimony, and thus is intended to reshape our understanding of the deep and ubiquitous reliance we have on the testimony of those around us.

Improving education is a key priority for governments around the world. While many suggestions on how best to achieve this are currently under debate, years of academic research have already revealed more about how to encourage change than is sometimes assumed. This volume brings together for the first time some of the most significant work of Karen Seashore Louis, one of the foremost thinkers and researchers in the field. Organizing for School Change presents a unique variety of research-based results from studies conducted over the past twenty-five years. What emerges is not an idealistic plan, but a realistic picture of what needs to be done if schools are to be made better. Drawing on a wide and comprehensive list of sources, the ideas brought together in this collection will prove invaluable and insightful reading, stimulating both newcomers and veterans of the field to consider educational research in new ways.
