The Originality of Descartes Theory about the Pineal Gland

René Descartes thought that the pineal gland is the part of the body with which the soul is most immediately associated. Several prominent historians (such as Soury, Thorndike and Sherrington) have claimed that this idea was not very original. We re-examine the evidence and conclude that their assessment was wrong. We pay special attention to the thesis about the pineal gland which Jean Cousin defended in January, 1641.     

Descartes and the pineal gland in animals: A frequent misinterpretation

Abstract

Rene Descartes presented a number of reasons for his choice of the pineal gland as a logical place for the soul to interact with the physical machinery of the body. It is often stated that one of his reasons was that be believed animals do not have pineal glands, whereas humans alone possess a soul and this small structure. This is a misinterpretation of Descartes. The philosopher knew that barnyard and other animals possess pineal glands, having seen this with his own eyes. His point was that the pineal is unique in humans only because of a special function — acting as the seat for the rational soul.

Die Deutschlandreise des René Descartes

Due to lacking reliable sources almost no details were available on the educational journey of the joung Descartes. Moreover, contradictions in several publications resulted in the doubt, whether these events, which are so important for the history of science, ever hapened at all. Folowing careful and comprehensive research at the City Archives Ulm, the Hessian City Archives Darmstadt and the Bavarian State Library in Munich the author found evidence that René Descartes met the mathematician and master fortress builder Johann Faulhaber in Ulm.¹ Now, the first summary of Descartes' travel report can be given based on further findings (in reliable sources) and corroborated by numerous facts.     

Gulliver meets Descartes: early modern concepts of age-related memory loss

Age-related memory loss was a marginal issue in medical discussions during early modern times and until well into the second half of the 17th century. There are many possible explanations: the lack of similar traditions in antiquity and in the Middle Ages, insufficient physiological and morphological knowledge of the brain, and the underlying conflict between idealistic and materialistic perspectives on the functions of the soul and the conditions of these in old age. After these boundaries had been pushed back by the influence of Cartesianism and Iatromechanism, the problem of age-related memory loss was increasingly regarded as a physical illness and began to receive more attention. This trend first occurred in medicine, before spreading to the literary world, where the novel "Gulliver's Travels" is one clear and famous example.     

Körpergefühl und Raumvorstellung: Leonardo und Descartes

“Experience and the conception of the world in science in transition to modern times” is the general subject. There are two different points to be made clear, i.e. 1. That the conception of the world had to be made imaginable by art before it could be taken over by science. The central perspective dates back to about three centuries before the time Descartes developed the co-ordinate system. 2. Furthermore it should be taken into account that it was first of all due to the lead of the painters (especially in the Italy of the Quattrocento’) that the possibility of making experiences had changed. In a space opened by a perspective view and seemingly thus appearing as measurable even the painted figures acquire a new reality. Due to his anatomic studies Leonardo could treat the natural movement of the figures shown in his paintings. It was the artists who first of all investigated optics and anatomy before relations could be measured with the aid of scientific methods ami before quantities — instead of qualities — could become the base of unbiased science, as called for by Galilei in 1623.     

Orderic Vitalis and the First Crusade

This article examines the narrative of the First Crusade written by the Norman monk and historian Orderic Vitalis, which spans Book IX of his Historia ecclesiastica. Though hitherto little-studied, Orderic's account of the First Crusade, which was probably written in 1135, occupies an important place in the Historia and reveals much about his wider historical method. The significance of Orderic's editorial interaction with Baldric of Bourgueil's Historia Ierosolimitana, through the omission and addition of material, forms the focus of the study. By making only a small number of insertions into the story of the First Crusade which he had inherited from Baldric, Orderic transformed its meaning so that it became suitable for incorporation into the Historia as a whole, linking the First Crusade to the history of his monastery, Saint-Evroult.
