Abstract: The book challenges the current view that personalism is primarily an early 20th-century phenomenon. The established definitions of personalism, mainly in terms of the American school of B. P. Bowne, are shown to fit broadly the positions of much earlier continental European and Scandinavian philosophers and theologians. The beginnings of specifically personalistic thought are traced to F. H. Jacobi’s criticism of pantheism, first set forth in the 1780s, and the work of the later F. W. J. Schelling. Its development is then identified in the work of selected, representative thinkers who, throughout the 19th century, build on or develop further positions established by Jacobi and Schelling, primarily the thinkers belonging to the broad current of so-called ‘speculative theism’ in Germany and in Sweden. The development of idealistic personalism in Britain by A. S. Pringle-Pattison, J. R. Illingworth, C. C. J. Webb and others is shown to be parallel to the emergence of the American school. It is argued that these should be seen as a continuation of the earlier European movement. Both the American and the British schools drew on the work of H. Lotze, but the book points to the neglected continental European background to Lotze, the current of personalistic, partly idealistic, and theistic philosophy of which Lotze’s work was only one, late variation. Discerning the central themes of the emerging worldview of personalism, the book establishes that they developed consistently in a broad, unitary movement with a distinct historical profile from the late 18th to the early 20th centuries, the nature and importance of which has heretofore been neglected in the history of philosophy and in historical theology.
