A reissue of the annotated edition of Roman Catholic priest John Seton's (1508/9-1567) treatise on logic, with notes by fellow logician Peter Carter (1530?-1590), initially printed in 1563. Dedicated to Bishop Gardiner as Chancellor of Cambridge, Dialectica, when first printed in 1545, concisely communicated emergent humanist Aristotelianism (though some remnant of medieval logic theory remained). Divided into sections, the book consists of brief statements followed by densely printed prose exposition. Carter's contribution was to reorganise the text for the purposes of teaching; adding definitions and rules after each section. Seton claimed to have been persuaded to publish by his colleagues John Cheke and Thomas Watson, though the work was widely circulated amongst his students in manuscript form prior to printing and remained the standard textbook on scholastic logic for more than a century, with the final reprint of this annotated edition appearing in 1639.
