Scarce first edition of the work known as the Port Royal Logic. The authors were leaders of the Port Royal movement, and the book displays the distinctive tone of earnest piety for which the movement became famous. La Logique was the most famous logic text of the seventeenth century and set the form of manuals of logic for the next two hundred years. In particular, its division of the subject into the theory of conception, of judgment, of reasoning, and of method established a psychologistic approach which dominated the field until the time of Frege.

A handbook on method rather than a study of formal logic in the strict sense, La Logique was strongly and consciously Cartesian: a development from Descartes’ Regulae rather than Aristotle’s Prior Analytics. It nevertheless made important technical advances, most notably in its distinction between the comprehension and extension of a term (a development of the medieval distinction between significatio and suppositio and a forerunner of Hamilton’s distinction between intension and extension); in its quasi-mathematical treatment of the rules of distribution, conversion and syllogistic; and in its formulation of the deduction theorem.

First edition of Richeome’s vindication of the Jesuits against the charges made by Antoine Arnaud in his famous defence of the University of Paris in 1594. Richeome (1544-1625), known as the ‘French Cicero’, was one of the leading French Catholic controversialists of his age and played a crucial role in overcoming prohibitions against the Jesuit order in France. In La vérité defendue he constructs a history of the Society of Jesus from its foundation, highlighting its achievements in education and the work of Jesuit missions in Japan, the Far East, America, and Brazil. The work was translated into Latin the following year.
