A characteristic hallmark of medieval astronomy is the replacement of Ptolemy’s linear precession with so-called models of trepidation, which were deemed necessary to account for divergences between parameters and data transmitted by Ptolemy and those found by later astronomers. Trepidation is commonly thought to have dominated European astronomy from the twelfth century to the Copernican Revolution, meeting its demise only in the last quarter of the sixteenth century thanks to the observational work of Tycho Brahe. The present article seeks to (...) challenge this picture by surveying the extent to which Latin astronomers of the late Middle Ages expressed criticisms of trepidation models or rejected their validity in favour of linear precession. It argues that a readiness to abandon trepidation was more widespread prior to Brahe than hitherto realized and that it frequently came as the result of empirical considerations. This critical attitude towards trepidation reached an early culmination point with the work of Agostino Ricci, who demonstrated the theory’s redundancy with a penetrating analysis of the role of observational error in Ptolemy’s Almagest.

The history of the transmission, recovery and posthumous influence of ancient scepticism is a fascinating chapter in the history of ideas. An extraordinary collection of philosophical texts and some of the most challenging arguments ever devised were first lost, then only partly recovered philologically, and finally rediscovered conceptually, leaving Cicero and Sextus Empiricus as the main champions of Academic and Pyrrhonian scepticism respectively. This chapter outlines what we know about this shipwreck and what was later salvaged from it.

In my article I present the conception of soul of Cornelius Agrippa based on his greatest work "De occulta philosophia" which is a kid of summa of natural and occult philosophy, hermeticism, cabbala, astrology, humanistic theology, medicine, and alchemy. Henricus Cornelius Agrippa von Nettesheim (1486-1535) was a famous renaissance philosopher, cabalist, astrologer and theologian whose contribution in renaissance philosophical deliberations is significant but still unknown in Poland. Agrippa's notion of soul is very important for his own project of new pure (...) magic which is described in his opus magnum. Therefore agrippian magic contains and perfects three kinds of knowledge: phisics, mathematics and theology. In the similary way Agrippa divided whole Cosmos in to three worlds. First and the most inferior world of the threefold Cosmos is the world of four elements of substance in Aristotle's meaning. The second one is the world of celestial bodies which comprises planets, stars and laws that rule them, and which is above the first world. The third one is the divine world of angels, soul of the world with platonic ideas and other intelligibilities. The three kinds of knowledge which Agrippa also called "regulative philosophy" are very useful for human in studying of each of three agrippian worlds. From this point of view also notion of humanity is very important for Agrippa. By the similarity between the macro- and microcosmos which appear in Agrippa's thought also human soul is threefold. Thus human soul contains in hierarchical order three parts viz.: idolum (which is the most inferior), ratio (being the middle part) and mens (which is on highest position in human soul). Each part has its own function which can be fully activated by God's light received by mens. In describing of functions of threefold soul Agrippa receives inspirations from prior philosophers like Aristotle, Awicenna or Awerroes. Another cause which emphases a great role of the agrippian conception of the soul is its connection with oryginal concepts of phantasy and threefold melancholy which is similar to the treepartite soul. Those two concepts are the examples of the influences of celestial powers which source is in stars and planets. (shrink)

This article seeks to revise the common scholarly assumption that in early modern Europe there was no single word for the study of the universe as a whole until the word “cosmology” appeared in Christian Wolff’s Cosmologia generalis methodo scientifica pertractata (1731). In fact, the term “cosmology” had circulated in both Latin and European languages since at least the 1530s in the context of critical appraisals of the largely dominant Aristotelian and scholastic frameworks. The aim of this study is to (...) unearth the earliest attempts to define cosmology as a philosophical discipline and, thereby, to highlight the lasting authority of traditional disciplinary boundaries.

Contrary to the common view, this paper suggests that the Hippocratic oath does not directly refer to the controversial subjects of euthanasia and abortion. We interpret the oath in the context of establishing trust in medicine through departure from Pantagruelism. Pantagruelism is coined after Rabelais' classic novel Gargantua and Pantagruel. His satire about a wonder herb, Pantagruelion, is actually a sophisticated model of anti-medicine in which absence of independent moral values and of properly conducted research fashion a flagrant over-medicalization of (...) human problems. Ultimately this undermines the therapeutic core of medicine itself. We contend that PAS is a case of such over-medicalization and that its institution creates medicophobia. This article does not express an opinion about euthanasia in general. Rather, we claim that physicians should learn from the oath and from Rabelais that they should keep their practice to medical care and not to exploit their expertise and social privileges for the sake of ulterior motives, even when their patients desire those goals.
