In 1675, Burchard de Volder became the first university physics professor to introduce the demonstration of experiments into his lectures and to create a special university classroom, The Leiden Physics Theatre, for this specific purpose. This is surprising for two reasons: first, early pre-Newtonian experiment is commonly associated with Italy and England, and second, de Volder is committed to Cartesian philosophy, including the view that knowledge gathered through the senses is subject to doubt, while that deducted from first principles is (...) certain. On the surface, it is curious that such a man would bring experiments to university physics. After all, in demonstrating experiments to his students, he was teaching them through their senses, not reason. However, if we consider the institutional context of de Volder’s teaching, we come to see de Volder’s Cartesian experimentalism as representative of a certain form of pre-Newtonian Dutch Cartesian science, as well as part of a larger tradition of teaching through observation at the University of Leiden. Considering de Volder’s institutional context will help us see that de Volder’s experimentalism was not in spite of his Cartesianism, but motivated by it. This paper will describe de Volder’s physics curriculum, the Theatre in which it was taught and how his work predates similar efforts in other European Universities. The second part will consider three aspects of the culture at the University of Leiden: a tradition of teaching through observation, a particular reception of Cartesianism, and an eclectic approach to the New Philosophy. The concluding portion shows how de Volder would have understood his enterprise in Cartesian terms. (shrink)

The ArgumentErnst Cassirer's fundamental conception of symbolism (symbolic pregnance) derives from what may be called a bio-medical model of semiotics, not a linguistic one. He employs both models in his philosophy of symbolic forms, but his notion of the “prototype and model of symbolism” was not derived from linguistics. The sources for his conception of symbolism include the ethnographic and anthropological literature he discovered in Aby Warburg's (1866–1929) Hamburg research library, findings of medical research on aphasia and related conditions, particularly (...) the work of Kurt Goldstein (1878–1965) and the theoretical biology of Jacob von Uexküll (1864–1944). The linguistic model of semiotics regards the bond between the signifier and the signified as purely arbitrary and conventional, but Cassirer traced meaning back to a “natural symbolism” of image-like configurations in bodily feeling and perception. In this way, his doctrine of symbolism assumed a form that undercut the distinction between philosophical Naturalism and Idealism. This helps to explain why in later years Cassirer developed his theory of Basic Phenomena. Cassirer's notion of the “prototype and model of symbolism” illustrates his method of thought, which eschews pure argument in favor of interaction with empirical research. (shrink)

En el presente trabajo se reflexiona el proceso de construcción del autoconocimiento propuesto por Ernst Cassirer. El objetivo es identificar la tensión entre la vida y espíritu como su antítesis básica y a las mediaciones simbólicas como el recurso cultural que posibilita la formación de un autoconcepto. A través de una revisión crítica de la Philosophie der symbolischen Formen y An Essay on Man, se sostendrá que, i) el autoconocimiento es un proyecto tríadico que integra cada fase previa, ii) que (...) requiere una investigación funcional de la obra y cultura humana para iii) sostener una tensión que distingue sin separar al agente como ser vivo y su autoconocimiento como un producto espiritual.
