 Sturm draws extensively on Aristotelian thinkers ranging from medieval scholastic authors, such as Gabriel Biel, to Renaissance and late early modern scholastic authors. The latter include Italian philosophers, for instance, Julius Caesar Scaliger, Andrea Caesalpino, Jacopo Zabarella, Giulio Pace, and Francisco Lana de Terzi; Dutch philosophers, such as Gijsbert Voet (Voetius); Spanish and Portuguese philosophers such as Gómez de Pereira, Pedro da Fonseca, Francisco de Toledo, Antonio Rubio, Francisco Suárez, Gabriel Vásquez, Pedro Hurtado de Mendoza, and Rodrigo de Arriaga; French philosophers, such as Samuel Maresius, Honoré Fabri, Jean Baptiste Du Hamel, and Pierre Daniel Huet; English philosophers, such as John Case and Gilbert Jack (Jacchaeus); and German Philosophers, such as Daniel Sennert, Christoph Scheibler, Johannes Zeisold, Johann Sperling, Jakob Thomasius, and Erhard Weigel. Sturm knows the German academic philosophical landscape very well, since these philosophers were influential in their respective fields (see Wundt 1938), or since they were either Sturm’s colleagues or teachers. The latter is true of Zeisold and Weigel.
