In his commentary on Aristotle’s Physics, John Buridan (c. 1300–1361) presents his well-known rejection of final causality. The main problem he sees with it is that it requires the cause to exist before the effect. Despite this, he retains the terminology of ends. This has led to some difficulty interpreting Buridan’s view. In this article, I argue that one should not misunderstand Buridan’s terminology and think that he still retains some use or explanatory function for final causality in nature. To make this point, I look first at Buridan’s text, but then also at three thinkers who discuss Buridan’s view in detail: Albert of Saxony (d. 1390), Paul of Venice (d. 1429), and Luis Coronel (d. 1531). They all have a very clear idea of what Buridan’s view was and understand that it entails a rejection of final causality, but they also all preserve his distinctive terminology. Paul of Venice especially discusses and criticizes Buridan’s view in detail. Besides confirming my interpretation of the rejection of final causality, this study also shows that the view was extremely influential well into the sixteenth century and attributed to Buridan throughout two centuries.

In this book, Henrik Lagerlund offers students, researchers, and advanced general readers the first complete history of what is perhaps the most famous of all philosophical problems: skepticism. As the first of its kind, the book traces the influence of philosophical skepticism from its roots in the Hellenistic schools of Phyrronism and the Middle Academy up to its impact inside and outside of philosophy today. Along the way, it covers skepticism during the Latin, Arabic, and Greek Middle Ages and during the Renaissance before moving on to cover Descartes's methodological skepticism and Pierre Bayle's super-skepticism in the seventeenth century. In the eighteenth century, it deals with Humean skepticism and the anti-skepticism of Reid and Kant, taking care to also include reflections on the connections between idealism and skepticism. The book covers similar themes in a chapter on G.E. Moore and Ludwig Wittgenstein, and then ends its historical overview with a chapter on skepticism in contemporary philosophy. In the final chapter, Lagerlund captures some of skepticism's impact outside of philosophy, highlighting its relation to issues like the replication crisis in science and knowledge resistance.

"Divided chronologically into four volumes, The Philosophy of Knowledge: A History presents the history of one of Western philosophy's greatest challenges: understanding the nature of knowledge. Each volume follows conceptions of knowledge that have been proposed, defended, replaced, and proposed anew. Knowledge in Medieval Philosophy covers the development of philosophical treatments of knowledge during the Middle Ages. It covers both Arabic and Latin philosophy, as well as a range of thinkers from the period including Avicenna, Averroes, Thomas Aquinas, John Duns Scotus, William Ockham, and John Buridan. In addition, the volume explores the growth of epistemological scepticism and the subsequent claims made by a variety of philosophers that knowledge was no longer fallible."--Bloomsbury Publishing.

Sixteenth Century philosophy was a unique synthesis of several philosophical frameworks, a blend of old and new, including but not limited to scholasticism, humanism, Neo-Thomism, Aristotelianism, and Stoicism. It was a century that witnessed culturally and philosophically significant moments whose impact still is felt today—some examples include the emergence of Jesuits, the height of the witchcraze, the Protestant Reformation, the rise of philosophical skepticism, Pietro Pomponazzi’s controversial reexamination of traditional understandings of the soul’s mortality, and the deflation of the metaphysical status of substantial forms. Unlike most historical overviews of this moment in philosophy’s history, The Routledge Companion to Sixteenth Century Philosophy does not simplify this colorful period with the application of the dichotomies traditionally applied to this century, such as the misguidingly clear line once drawn between scholasticism and humanism. The Companion includes essays covering the following astonishingly diverse set of topics: philosophical methodologies of the time, the importance of the discovery of the new world, the rise of classical scholarship, trends in logic and logical theory, Nominalism, Avveroism, Neo-Thomism, the Jesuits, the Reformation, Neo-stoicism, the soul’s immortality, witchcraft, Skepticism, the philosophies of language and science and politics, Cosmology, women’s rights, the nature of the understanding, causality, ethics, freedom of the will, natural law, the emergence of the individual in society, the nature of wisdom, and the love of god. And, throughout, the Companion seeks not to compartmentalize these philosophical matters, but instead to show that close attention paid to their continuity may help reveal both the diversity and the profound coherence of the philosophies that emerged in the sixteenth century

For a long time scholars ignored Anselm of Canterbury’s dialogue, De grammatico. It was not until D. P. Henry’s investigations in the 1960s and 70s that it was seriously studied. He showed that it was an important work, but his interpretation was peculiar. The main point of it was to show that Anselm thought traditional logic inadequate for analyzing logical problems and that he wanted to establish a new language that was better suited for the task. Henry also argued that the logical system of the Polish logician, Lesniewski, best captured Anselm’s new logical language.It is only very recently that his interpretation has been challenged. In a paper from 2000, M. M. Adams argued that De grammatico should be seen as an introduction for students to Aristotle’s Categories . She is much closer to the truth than Henry, but Anselm’s work seems too sophisticated to be an introduction, even though the problem he is dealing with

The chapter gives a general description of philosophical psychology as it was practiced and taught in the sixteenth century at three of the most important universities of the time, the universities of Erfurt, Padua, and Bologna. Contrary to received notions of the Renaissance it argues that the sixteenth-century philosophical psychology was tightly bound to the Aristotelian tradition. At the University of Erfurt, philosophical psychology was developed with strong adherence to the basic doctrines of Buridanian via moderna, as it had been taught for over a century. The Buridanian approach dominated especially discussions on the metaphysical nature of the human soul and disputes about universal realism versus nominalism. The situation was somewhat different at the universities of Bologna and Padua. The connections between these two universities were close, and they can be seen as developing one and the same Aristotelian tradition. Although the works produced were rather eclectic in nature, they shared research topics as well as conceptual and methodological frameworks which contributed to the unity of the school. In Bologna and Padua, Averroës had a central position as an authority cited and criticized; and philosophical questions concerning the immortality of the soul and the nature of the intellectual species attracted continuous interest. The development of philosophical psychology was also influenced by the special organizational situation of these universities: theology had a relatively unimportant position, and medicine instead had continuous impact on teaching.
