Transcendental Magic is a classic of occultism, prized for its wide-ranging wisdom, thorough guidance and revelatory contents. Written by Eliphas Levi in the mid-19th century, Transcendental Magic offers seekers of occult knowledge a bounty of guidance and knowledge. Informed by research spanning many centuries of arcane arts, the author offers us profound guidance to the ceremonial rituals one must perform in order to make contact with spirits and other non-corporeal entities of the universe. In Levi's explanations we encounter various figures of occult lore. Monad is synonymous with God; the creator of everything contained in our physical plane. Derived from the Pythagorean school, through Levi we learn how Monad interacts with the creation. This discussion is related to the Kabbalah, which attempts to define the relationship between what is infinite and what is finite.

The goal of this book is to introduce a reader to a new philosophy of teaching and learning physics - Investigative Science Learning Environment, or ISLE (pronounced as a small island). ISLE is an example of an "intentional" approach to curriculum design and learning activities (MacMillan and Garrison 1988 A Logical Theory of Teaching: Erotetics and Intentionality). Intentionality means that the process through which the learning occurs is as crucial for learning as the final outcome or learned content. In ISLE, the process through which students learn mirrors the practice of physics.

This book uses art photography as a point of departure for learning about physics, while also using physics as a point of departure for asking fundamental questions about the nature of photography as an art. Although not a how-to manual, the topics center around hands-on applications, sometimes illustrated by photographic processes that are inexpensive and easily accessible to students (including a versatile new process developed by the author, and first described in print in this series). A central theme is the connection between the physical interaction of light and matter on the one hand, and the artistry of the photographic processes and their results on the other. This is the third volume in this three-part series that uses art photography as a point of departure for learning about physics, while also using physics as a point of departure for asking fundamental questions about the nature of photography as an art. It focuses on the physics and chemistry of photographic light-sensitive materials, as well as the human retina. It also considers the fundamental nature of digital photography and its relationship to the analog photography that preceded it.

Since the publication of the edition of John Blund's Tractatus de anima by the British Academy in 1970 there has been widespread acceptance of the importance of this text for the history of thought. Blund (ca. 1175-1248) was probably one of the first commentators on the libri naturales at Paris before the prohibition of 1210, and later introduced them to Oxford. Indeed, apart from the prohibitions of 1210 and 1215, the De anima of Blund is the one text which sheds light on the first reception of Aristotle at Paris. The text was probably composed at Paris, before 1204. Blund taught arts at Paris ca. 1200-1205, then at Oxford towards 1207-1209. He returned to study theology at Paris during the interdict (1208-1214) and the contemporaneous suspension of the schools at Oxford (1209-1214). He was regent in theology at Paris for twelve years, and taught theology at Oxford after 1229. With the Tractatus a whole area of philosophical speculation - namely Greek and Arabic psychology - arrived at Oxford, where it would continue to grow and be debated throughout the century. Blund did not know Averroes but he reflects the state of Latin Aristotelianism during the first third of the thirteenth century. Like his contemporaries Blund regarded the De anima of Avicenna as a commentary on Aristotle; indeed they found it clearer than the text of Aristotle and were guided by it. Blund is faithful to Aristotle and to Avicenna, rejecting, for example, the binarium famosissimum drawn from the Fons vitae of Avicebron. In expounding the doctrine of Aristotle and following the plan laid out by Avicenna, he considers the arguments for and against before offering his own reasoned position in the solutio. He defends the role of the philosopher as considering the nature of the soul and as distinct from theological considerations. This new English translation makes available this important text to a wider audience of scholars interested in philosophy, theology, medieval history and the history of science and psychology. Students who are learning medieval Latin will be able to follow the original Latin with the help of the parallel translation and text notes.
