"Peter of Limoges's Moral Treatise on the Eye is arguably the single most important medieval text situated at the junction of two dynamic areas of intellectual history: the history of optical science and the history of pastoral care."--Page [4].

In this original and fascinating book, Stuart Clark investigates the cultural history of the senses in early modern Europe. At a time in which the nature and reliability of human vision was a focus for debate in medicine, art theory, science, and philosophy, there was an explosion of interest in the truth (or otherwise) of miracles, dreams, magic, and witchcraft. Was seeing really believing? Vanities of the Eye wonderfully illustrates how this was woven into contemporary works such as Macbeth - deeply concerned with the dangers of visual illusion - and exposes early modern theories on the relationship between the real and the virtual.

Henry Allison examines the central tenets of Hume's epistemology and cognitive psychology, as contained in the Treatise of Human Nature. Allison takes a distinctive two-level approach. On the one hand, he considers Hume's thought in its own terms and historical context. So considered, Hume is viewed as a naturalist, whose project in the first three parts of the first book of the Treatise is to provide an account of the operation of the understanding in which reason is subordinated to custom and other non-rational propensities. Scepticism arises in the fourth part as a form of metascepticism, directed not against first-order beliefs, but against philosophical attempts to ground these beliefs in the "space of reasons." On the other hand, Allison provides a critique of these tenets from a Kantian perspective. This involves a comparison of the two thinkers on a range of issues, including space and time, causation, existence, induction, and the self. In each case, the issue is seen to turn on a contrast between their underlying models of cognition. Hume is committed to a version of the perceptual model, according to which the paradigm of knowledge is a seeing with the "mind's eye" of the relation between mental contents. By contrast, Kant appeals to a discursive model in which the fundamental cognitive act is judgment, understood as the application of concepts to sensory data, Whereas regarded from the first point of view, Hume's account is deemed a major philosophical achievement, seen from the second it suffers from a failure to develop an adequate account of concepts and judgment.

"Neiman reclaims the vocabulary of morality--good and evil, heroism and nobility--as a lingua franca for the twenty-first century. In constructing a framework for taking responsible action on today's urgent questions, [she] reaches back to the eighteenth century, retrieving a series of values--happiness, reason, reverence, and hope--held high by Enlightenment thinkers. In this ... updated edition, Neiman reflects on how the moral language of the 2008 presidential campaign has opened up new political and cultural possibilities in America and beyond"--Back cover.

Enquiry concerning the principles of morals / Hume, David, 1711-1776.

In Measuring Shadows, Raz Chen-Morris demonstrates that a close study of Kepler’s Optics is essential to understanding his astronomical work and his scientific epistemology. He explores Kepler’s radical break from scientific and epistemological traditions and shows how the seventeenth-century astronomer posited new ways to view scientific truth and knowledge. Chen-Morris reveals how Kepler’s ideas about the formation of images on the retina and the geometrics of the camera obscura, as well as his astronomical observations, advanced the argument that physical reality could only be described through artificially produced shadows, reflections, and refractions. Breaking from medieval and Renaissance traditions that insisted upon direct sensory perception, Kepler advocated for instruments as mediators between the eye and physical reality, and for mathematical language to describe motion. It was only through this kind of knowledge, he argued, that observation could produce certainty about the heavens. Not only was this conception of visibility crucial to advancing the early modern understanding of vision and the retina, but it affected how people during that period approached and understood the world around them.

The New York Times–bestselling author of The Believing Brains explores how science makes us better people. From Galileo and Newton to Thomas Hobbes and Martin Luther King, Jr., thinkers throughout history have consciously employed scientific techniques to better understand the non-physical world. The Age of Reason and the Enlightenment led theorists to apply scientific reasoning to the non-scientific disciplines of politics, economics, and moral philosophy. Instead of relying on the woodcuts of dissected bodies in old medical texts, physicians opened bodies themselves to see what was there; instead of divining truth through the authority of an ancient holy book or philosophical treatise, people began to explore the book of nature for themselves through travel and exploration; instead of the supernatural belief in the divine right of kings, people employed a natural belief in the right of democracy. In The Moral Arc, Shermer explains how abstract reasoning, rationality, empiricism, skepticism—scientific ways of thinking—have profoundly changed the way we perceive morality and, indeed, move us ever closer to a more just world. “Michael Shermer is a beacon of reason in an ocean of irrationality.” —Neil deGrasse Tyson “A memorable book, a book to recommend and discuss late into the night.” —Richard Dawkins “[A] brilliant contribution . . . Sherman’s is an exciting vision.” —Nature

Offering a new reading of Spinoza's masterpiece, Smith asserts that the 'Ethics' is a celebration of human freedom and its attendant joys and responsibilities and should be placed among the great founding documents of the Enlightenment.
