Iamblichus was once considered one of the great philosophers. The Emperor Julian followed Iamblichus's teachings to guide the restoration of traditional pagan cults in his campaign against Christianity. Although Julian was unsuccessful, Iamblichus's ideas persisted well into the Middle Ages and beyond. His vision of a hierarchical cosmos united by divine ritual became the dominant worldview for the entire medieval world. Even Ralph Waldo Emerson wrote that he expected a reading of Iamblichus to cause a "revival in the churches." But modern scholars have dismissed him, seeing theurgy as ritual magic or "manipulation of the gods." Shaw, however, shows that theurgy was a subtle and intellectually sophisticated attempt to apply Platonic and Pythagorean teachings to the full expression of human existence in the material world.

Living Theurgy is a masterpiece combining scholarly excellence with lucid practicality. Theurgy ('god-working') is a combination of ritual mystical practices interwoven with philosophy and theology. It was developed by Iamblichus and other Neoplatonists inspired by the works of philosophers including Plato, Aristotle and Pythagoras, and Julian the Chaldean. Author and scholar Jeffrey Kupperman elucidates and makes accessible the core ideologies and practices of Theurgy, which evolved through more than 1000 years of Platonic philosophy and cultural transformations. Kupperman guides the reader through the contemplative and theurgical practices used by the Neoplatonists to create effective spiritual transformation in the practitioner. Philosophia (Philosophy) as the foundation of Theurgy is explored through techniques such as lectio divina ('divine reading') contemplation and visualisation. It focuses on discussion of key concepts including virtue, wisdom, bravery, temperance, justice, evil, political philosophy, beauty and love. Theologia (Theology) considers the One, also known as the Good, which is the source of all, through the spectrum of monotheism, polytheism and panentheism. It also explores different views regarding the nature and functions of the Demiurge, angels and daimons, and the human soul, and the practices of Theurgy, including the use of hymns and prayers. Theourgia (Theurgy) focuses on the practices, from purification and the use of signs, symbols and tokens to talismancy and the ensouling of eikons (divine images). The work concludes with a complete guide to the Invocation of the Personal Daimon, an essential step in the theurgic process of purification and illumination in seeking the Divine. Living Theurgy is a literary psychopomp for practitioners seeking effective methods of developing their knowledge and relationship with the divine through Neoplatonic praxis. It is essential reading for all those interested in traditional forms of magical, philosophical, and religious practice, and the history of the western mysteries. "Philosophy is purifying, religion illuminating, but theurgy is uplifting." Introduction, Jeffrey Kupperman

''As a writer I thought that magical arts were language driven. I mean, we call them 'spells.' We have 'Words of Power, ' mantras, chants, and invocations. But with mathematics we have something else entirely. If I write down I saw three bluebonnets blooming today, you know exactly how many (even if you don't have the pleasure of knowing that it is the state flower of Texas). In fact, you can know the number even if you do not know English. In fact, you can know the number even if every single human perishes and you are some visiting alien from Tau Ceti. This would be true as your ability to grasp the Fundamental Theorem of the Calculus or the quadratic formula or )amusingly enough) Goedel's Incompleteness Theorems. Mathematics is where the mind can grasp the stuff of the Cosmos. We need only think of the terrible flash seen on Hiroshima on August 6, 1945, or the beauties of the Mandelbrot set, or watch children play at cutting a Moebius, to understand that math is at he secret heat of the physical world. And that math is the key to 'wonderworking'.'' -- Don We

In this volume, the relationships between two of the most vital currents in Western thought are examined by a group of nineteen internationally known specialists in a variety of disciplines—classics, patristics, philosophy, theology, history of ideas, and literature. The contributing scholars discuss Neoplatonic theories about God, creation, man, and salvation, in relation to the ways in which they were adopted, adapted, or rejected by major Christian thinkers of five periods: Patristic, Later Greek and Byzantine, Medieval, Renaissance, and Modern. Contributors include G.-H. Allard, A. Hilary Armstrong, Elizabeth Bieman, Linos Benakis, Henry Blumenthal, Mary T. Clark, Norris Clarke, John Dillon, Cornelio Fabro, John N. Findlay, Maurice de Gandillac, Edward P. Mahoney, Bernard McGinn, Dominic J. O'Meara, John J. O'Meara, Jean Pépin, Mary Carman Rose, Henri-Dominique Saffrey, Charles B. Schmitt, and Gérard Verbeke.

Theurgy means "the science or art of divine works." In alchemy, this process is called the "Great Work," which is the purification and exaltation of our "lower" nature by the proper application of esoteric principles, so that it may become united with its higher counterparts, whereby we may attain spiritual, and ultimately divine, consciousness. Drawing on the teachings of the Egyptian, Greek, and Hebrew mystery schools and quoting extensively from important alchemical writers, Garstin details this process of purification. Students who are curious about alchemy but daunted by the body of its literature and its strange allegories will find this book to be an excellent introduction. Garstin discusses source alchemical works and clearly explains what their esoteric symbolism means. With the information in this book, students of alchemy can then proceed to make a more informed exploration of the alchemical works and other writings of the Western Mystery Tradition.
