I: First published in 1626, Institutionum logicarum was widely used at many universities in both Europe and America to teach the most complex principles of logic. The author’s neo-Aristotelianism exerted a strong influence in the next generation of philosophers at Leiden and his textbooks were still popular after his death in 1635. Burgersdijk (or Burgersdicius, 1590 – 1635) was chair of logic and moral philosophy at Leiden University.

II: First published in 1650, Heereboord’s work on logic is an explanation of the work of Burgersdikj, his teacher and predecessor, through annotations and examples, as well as explanations that were requested by the deans of different schools (as he states in the dedication). It contains the 1651 edition of the second part entitled Praxis Logica with colophon dated 1651.

Heereboord (1613-1661), a Cartesian logician and philosopher from the Netherlands, is credited for introducing the writings of Descartes in the University of Leiden where he taught logic. He was the main representative of the Philosophia Novantiquea movement. He shared his teacher’s focus on the utilitarian function of logic. There is evidence that Spinoza occasionally attended his lectures.

These two works on logic are particularly noteworthy for combining a logic textbook with commentary, written respectively by one professor and his successor at Leiden University.
