A provocative new look at concepts of the present, their connection to ideas about time, and their effect on literature, art, and culture The problem of the present—what it is and what it means—is one that has vexed generations of thinkers and artists. Because modernity places so much value on the present, many critics argue that people today spend far too much time in the here and now—but how can we tell without first knowing what the here and now actually is? What Is the Present? takes a provocative new look at this moment in time that remains a mystery even though it is always with us. Michael North tackles puzzles that have preoccupied philosophy, neuroscience, psychology, history, and aesthetic theory and examines the complex role of the present in painting, fiction, and film. He engages with a range of thinkers, from Aristotle and Augustine to William James and Henri Bergson. He draws illuminating examples from artists such as Fra Angelico and Richard McGuire, filmmakers like D. W. Griffith and Christopher Nolan, and novelists such as Elizabeth Bowen and Willa Cather. North offers a critical analysis of previous models of the present, from the experiential present to the historical period we call the contemporary. He argues that the present is not a cosmological or experiential fact but a metaphor, a figurative relationship with the whole of time. Presenting an entirely new conception of the temporal mystery Georg Lukács called the "unexplained instant," What Is the Present? explores how the arts have traditionally represented the present—and also how artists have offered radical alternatives to that tradition.

Thomas Hankins and Robert Silverman investigate an array of instruments from the seventeenth through the nineteenth century that seem at first to be marginal to science--magnetic clocks that were said to operate by the movements of sunflower seeds, magic lanterns, ocular harpsichords (machines that played different colored lights in harmonious mixtures), Aeolian harps (a form of wind chime), and other instruments of "natural magic" designed to produce wondrous effects. By looking at these and the first recording instruments, the stereoscope, and speaking machines, the authors show that "scientific instruments" first made their appearance as devices used to evoke wonder in the beholder, as in works of magic and the theater. The authors also demonstrate that these instruments, even though they were often "tricks," were seen by their inventors as more than trickery. In the view of Athanasius Kircher, for instance, the sunflower clock was not merely a hoax, but an effort to demonstrate, however fraudulently, his truly held belief that the ability of a flower to follow the sun was due to the same cosmic magnetic influence as that which moved the planets and caused the rotation of the earth. The marvels revealed in this work raise and answer questions about the connections between natural science and natural magic, the meaning of demonstration, the role of language and the senses in science, and the connections among art, music, literature, and natural science. Originally published in 1995. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Why are there so many psychologists in America today? Psychologists on the March seeks to answer this question through historical analysis of the middle years of this century. The book argues that the Second World War exerted a profound influence on the shape and structure of the field, transforming it from a small academic subject into an enormous mental health profession. It provides a case study of the interaction of scientific expertise and professional practice in the construction of a modern discipline.
