The significance of Henry More's vitalist philosophy in the history of ideas has been realized relatively recently, as the bibliography will reveal. The general neglect of the Cambridge Platonist movement may be attributed to the common prejudice that its chief exponents, especially More, were obscure mystics who were neither coherent in their philosophical system nor attractive in their prose style. I hope that this modern edition of More's principal treatise will help to correct this unjust im pression and reveal the keenness and originality of More's intellect, which sought to demonstrate the relevance of classical philosophy in an age of empirical science. The wealth of learning -- ranging as it does from Greek antiquity to 17th century science and philosophy -- that informs More' s intellectual system of the universe should, in itself, be a recom mendation to students of the history of ideas. Though, for those in search of literary satisfaction, too, there is not wanting, in More's style, the humour, and grace, of a man whose erudition did not divorce him from a sympathetic understanding of human contradictions. As for More's elaborate speculations concerning the spirit world in the final book of this treatise, I think that we would indeed be justified in regarding their combination of classical mythology amd scientific naturalism as the literary and philosophical counterpart of the great celestial frescoes of the Baroque masters.

This is the first complete modern edition of Henry More's long philosophical poem, A Platonick Song of the Soul (1647). This early work, written in Spenserian stanzas, is a sustained literary presentation of the Neoplatonic doctrine of the immateriality and immortality of the soul. The Introduction to this book discusses both the literary background of the work and its varied philosophical and scientific sources, from Plotinus to Ficino and Galileo.

The book surveys the key metaphysical contributions of the Cambridge Platonist, Henry More (1614–1687). It deals with such interwoven topics as: the natures of body and spirit, and the question of whether or not there is a sharp ontological division between them; the nature of spatial extension in relation to each; the composition and governance of the physical world, including More’s theories of Hyle, atoms, vacuum, and the Spirit of Nature; and the life of the human soul, including its pre-existence. It approaches these topics and the systematic connections between them both historically and analytically, and seeks to do justice to the ways in which More’s system developed and changed—sometimes quite dramatically—over the course of his long career. It also explores More's intellectual relations with both his own inspirations (Plotinus, Origen, Ficino, Descartes, etc.) and with those who responded, whether positively or negatively, to his work (Leibniz, Locke, Boyle, Newton, etc.).
