Intentionality - the relationship between conscious states and their objects - is one of the most discussed topics in contemporary debates in philosophy of mind, cognitive neuroscience and the study of consciousness. Long a foundational concept in Phenomenology, it has also received considerable coverage in the writings of analytic philosophers. This book is the first study to offer an impartial, well-informed assessment of the two traditions' approaches through an in-depth investigation of the principal thinkers' ideas, so that their positions emerge side-by-side, converging and diverging on certain shared themes. Beginning with a historical discussion of the development of the term in the work of Continental thinkers in the 19th and early 20th centuries, the book considers the work of Brentano and Husserl and subsequent existentialist critiques. From there, it explores how empirical-analytic philosophers took up the topic, drawn as they were to materialist and computer models of the mind. Finally MacDonald presents a new hybrid' account of intentionality that will be a crucial work for scholars working on consciousness and the mind.

Exploring the 'roads less travelled', MacDonald continues his monumental essay in the history of ideas. The history of heterodox ideas about the concept of mind takes the reader from the earliest records about human nature in Ancient Egypt, the Ancient Near East, and the Zoroastrian religion, through the secret teachings in the Hermetic and Gnostic scriptures, and into the transformation of ideas about the mind, soul and spirit in the late antique and early medieval epochs. These transitions include discussion of the influence of Central Asian shamanism, Manichean ideas about the soul in light and darkness, and Neoplatonic theurgy, 'working-on-god-within'. Sections on the medieval period are concerned with the rediscovery of magical practices and occult doctrines from Roger Bacon to Francis Bacon, the adaptation of Neoplatonic and esoteric ideas in the medieval Christian mystics, and the survival of these ideas mixed with natural science in the works of von Helmont, Leibniz and Goethe. The book concludes with an investigation of the many forms of dualism in accounts of the human mind and soul, and the concept of dual-life which underpins our aspiration to understand how humans could have an immortal nature like the gods.

In the 20th century theorists of mind were almost exclusively concerned with various versions of the materialist thesis, but prior to current debates accounts of soul and mind reveal an extraordinary richness and complexity which bear careful and impartial investigation. This book is the first single-authored, comprehensive work to examine the historical, linguistic and conceptual issues involved in exploring the basic features of the human mind - from its most remote origins to the beginning of the modern period. MacDonald traces the development of an armature of psychical concepts from the Old Testament and Homer's works to the 18th century advocacy of an empirical science of the mind. Along the way, detailed attention is paid to the Presocratics, Plato, Aristotle, the Stoics and Epicurus, before turning to look at the New Testament, Neoplatonism, Augustine, Medieval Islam, Aquinas and Dante. Treatment of Renaissance theories is followed by an unusual (perhaps unique) chapter on the words "soul" and "mind" in English literature from Chaucer to Shakespeare; the story then rejoins the mainstream with analyses of Descartes, Spinoza, Leibniz, Hobbes, Locke, Berkeley, and Hume. Chapter-focused bibliographies.

An alternative history of philosophy has endured as a shadowy parallel to standard histories, although it shares many of the same themes. It has its own founding texts in the late ancient Hermetica, from whence flowed three broad streams of thought: alchemy, astrology, and magic. These thinkers' attitude toward philosophy is not one of detached speculation but of active engagement, even intervention. It appeared again in the European Middle Ages, in the Renaissance with Rabelais, Paracelsus, Agrippa, Ficino, and Bruno; and in the early modern period with John Dee, Robert Fludd, Jacob Boehme, Thomas Browne, Kenelm Digby, van Helmont, and Isaac Newton. In the 18th-19th centuries, this book considers Lichtenberg's Fragments, Berkeley's Siris, Swedenborg, Hegel, von Baader, and great Romantics such as Novalis, Goethe, S. T. Coleridge, and E. A. Poe, as well as Nietzsche; and in the 20th century it turns to the great modernist literature of Fernando Pessoa, Robert Musil, Ernst Bloch, and P. K. Dick.

Philosopher, alchemist, and privateer, Kenelm Digby (1603-1665) cut a striking figure across Europe in the middle of the 17th century. Digby corresponded with Galileo, Descartes, Gassendi, Gilbert and Harvey, and was one of the founding members of the Royal Society. In 1644 he published his major philosophical work, Two Treatises: Of Bodies and of Man's Soul - the first comprehensive philosophical work in the English language. In the Two Treatises Digby discussed at length a vast array of philosophical ideas: elements, matter, mechanism, motion, force and causation, as well as sensation, perception, memory, imagination, intellect, reason, and immortality. MacDonald's edition is the first scholarly edition of this great work since it went out of print in 1669: it offers a normalized text, copious annotations, and a lengthy introduction which situates Digby's ideas in the currents of 17th century philosophical thought.
