TOMUS PRIMUS In this first volume of his Cursus Theologicus , John Poinsot summarizes the four books of Peter Lombard's Sentences , gives an introduction to the theology of St. Thomas Aquinas, explains the connection and order of the whole Summa Theologiae , provides a treatise lauding and defending the authoritative teaching of St. Thomas, and exposits the first seven questions of the Prima Pars of the Summa Theologiae . The work of John Poinsot, also known as Joannes a Sancto Thoma (though as John Deely noted, his name has often been given in many other variations, across English, Portuguese, Italian, Spanish, French, and Latin), has long been the victim of great neglect. His Cursus Philosophicus was critically-edited and published in the 1930s under the blessed endeavor of Beatus Reiser, O.S.B., and reprinted in 2008 by Olms Verlag. Currently, his Cursus Theologicus is undergoing a similar critical evaluation and re-publication. Though the facsimile reprint volumes here are taken from the non-critical and therefore somewhat unreliable Latin text Vives edition of the 1880s, they are presented in full and affordably. The far superior critical Solesmes edition has thus far reached only the fifth volume (in 2015) and sits outside the price-range of many. In an effort to promote the study and understanding of Poinsot, these ten volumes (the tenth being the index to the whole series) are presented as-is, in a reasonably durable, reasonably affordable set. All the volumes are entirely in Latin.
