This book argues that the Constitution has a dual nature. The first aspect, on which legal scholars have focused, is the degree to which the Constitution acts as a binding set of rules that can be neutrally interpreted and externally enforced by the courts against government actors. This is the process of constitutional interpretation. But according to Keith Whittington, the Constitution also permeates politics itself, to guide and constrain political actors in the very process of making public policy. In so doing, it is also dependent on political actors, both to formulate authoritative constitutional requirements and to enforce those fundamental settlements in the future. Whittington characterizes this process, by which constitutional meaning is shaped within politics at the same time that politics is shaped by the Constitution, as one of construction as opposed to interpretation.

Whittington goes on to argue that ambiguities in the constitutional text and changes in the political situation push political actors to construct their own constitutional understanding. The construction of constitutional meaning is a necessary part of the political process and a regular part of our nation's history, how a democracy lives with a written constitution. The Constitution both binds and empowers government officials. Whittington develops his argument through intensive analysis of four important cases: the impeachments of Justice Samuel Chase and President Andrew Johnson, the nullification crisis, and reforms of presidential-congressional relations during the Nixon presidency.

Context Providers explores the ways in which digital art and culture are challenging and changing the creative process and our ways of constructing meaning. The authors introduce the concept of artists as context providers—people who establish networks of information in a highly collaborative creative process, blurring boundaries between disciplines. Technological change has affected the function of art, the role of the artist, and the way artistic productions are shared, creating a need for flexible information filters as a framework for establishing meaning and identity. Context Providers considers the work of media artists today who are directly engaging the scientific community through collaboration, active dialogue, and creative work that challenges the scientific.

In communities throughout precontact Mesoamerica, calendar priests and diviners relied on pictographic almanacs to predict the fate of newborns, to guide people in choosing marriage partners and auspicious wedding dates, to know when to plant and harvest crops, and to be successful in many of life's activities. As the Spanish colonized Mesoamerica in the sixteenth century, they made a determined effort to destroy these books, in which the Aztec and neighboring peoples recorded their understanding of the invisible world of the sacred calendar and the cosmic forces and supernaturals that adhered to time. Today, only a few of these divinatory codices survive. Visually complex, esoteric, and strikingly beautiful, painted books such as the famous Codex Borgia and Codex Borbonicus still serve as portals into the ancient Mexican calendrical systems and the cycles of time and meaning they encode.

In this comprehensive study, Elizabeth Hill Boone analyzes the entire extant corpus of Mexican divinatory codices and offers a masterful explanation of the genre as a whole. She introduces the sacred, divinatory calendar and the calendar priests and diviners who owned and used the books. Boone then explains the graphic vocabulary of the calendar and its prophetic forces and describes the organizing principles that structure the codices. She shows how they form almanacs that either offer general purpose guidance or focus topically on specific aspects of life, such as birth, marriage, agriculture and rain, travel, and the forces of the planet Venus. Boone also tackles two major areas of controversy—the great narrative passage in the Codex Borgia, which she freshly interprets as a cosmic narrative of creation, and the disputed origins of the codices, which, she argues, grew out of a single religious and divinatory system.
