Book excerpt: This book deals with alchemy's rich, multifaceted tradition from three perspectives - history, psychology, and nomothetic science - something rarely seen in other books on the same subject. Part I - Alchemy: Histories concerns the interdisciplinary and cross-cultural intercourse that occasioned the rich tapestry of alchemical tropes, themes, narratives, and pursuits, addressing the harmonious fusion of Hellenistic nature philosophy, Gnostic mythology, and Egyptian crafts and metallurgical practices in late antiquity - and much more, including the alchemy's role during the Renaissance, its influence on Jacob Boehme’s theosophy, and its medieval imagery's integral role in Jung’s theory of the collective unconscious. Part 2 - Alchemy: Processes of the Mind looks at the alchemical opus and its stages in the context of analytical, developmental, and clinical psychology, offering psychological interpretations of the Splendor Solis plates and integrated alchemical interpretations of personality, personal growth, and the human condition. Part 3 - Alchemy: The Noetic Science examines the empirical validity of alchemical theory and pursuit, addressing the viability of metallic transmutation, the theory of esoteric correspondences - the planet-metal connections - and how its animistic paradigm and principles of transformation might connect to more innovative, radical ideas emergent within the nomothetic disciplines.
