This book aims at beginning the rewriting of the history of skepticism by highlightening the medieval sources of the modern skeptical discussions.

When William of Ockham lectured on Lombard's Sentences in 1317-1319, he articulated a new theory of knowledge. Its reception by fourteenth-century scholars was, however, largely negative, for it conflicted with technical accounts of vision and with their interprations of Duns Scotus. This study begins with Roger Bacon, a major source for later scholastics' efforts to tie a complex of semantic and optical explanations together into an account of concept formation, truth and the acquisition of certitude. After considering the challenges of (...) Peter Olivi and Henry of Ghent, Part I concludes with a discussion of Scotus's epistemology. Part II explores the alternative theories of Peter Aureol and William of Ockham. Part III traces the impact of Scotus, and then of Aureol, on Oxford thought in the years of Ockham's early audience, culminating with the views of Adam Wodeham. Part IV concerns Aureol's intellectual legacy at Paris, the introduction of Wodeham's thought there, and Autrecourt's controversies. (shrink)

This is the third edition of a classic book first published in 1960, which has sold thousands of copies in two paperback edition and has been translated into several foreign languages. Popkin's work ha generated innumerable citations, and remains a valuable stimulus to current historical research. In this updated version, he has revised and expanded throughout, and has added three new chapters, one on Savonarola, one on Henry More and Ralph Cudworth, and one on Pascal. This authoritative treatment of the (...) theme of scepticism and its historical impact will appeal to scholars and students of early modern history now as much as ever. (shrink)

The important work, exquisitely translated by Mark Wauck, brings the essential elements of philosophy into view as a cohesive, readily understandable, and erudite structure, and does so rigorously in the best tradition of St. Thomas.

The subject is Sextus Empiricus, one the chief sources of information on ancient philosophy and one of the most influential authors in the history of skepticism. Sextus' works have had an extraordinary influence on western philosophy, and this book provides the first exhaustive and detailed study of their recovery, transmission, and intellectual influence through Late Antiquity, the Middle Ages, and the Renaissance. This study deals with Sextus' biography, as well as the history of the availability and reception of his works. (...) It also contains an extensive bibliographical section, including editions, translations, and commentaries. (shrink)

The series Studies and Texts in Scepticism contains monographs, translations, and collected essays exploring scepticism in its dual manifestation as a purely philosophical tradition and as a set of sceptical strategies, concepts, and attitudes in the cultural field - especially in religions, perhaps most notably in Judaism. In such cultural contexts scepticism manifests as a critical attitude towards different dimensions and systems of secular or revealed knowledge and towards religious and political authorities. It is not merely an intellectual or theoretical (...) worldview, but a critical form of life that expresses itself in such diverse phenomena as religion, literature, and society. Further book series of the Maimonides Centre for Advanced Studies are Jewish Thought, Philosophy, and Religion and the Yearbook of the Maimonides Centre for Advances Studies. (shrink)

It is a standing temptation for philosophers to find anticipations of their own views in the great thinkers of the past, but few have been so bold in the search for precursors, and so utterly mistaken, as Berkeley when he claimed Plato and Aristotle as allies to his immaterialist idealism. InSiris: A Chain of Philosophical Reflexions and Inquiries Concerning the Virtues of Tar-Water, which Berkeley published in his old age in 1744, he reviews the leading philosophies of antiquity and finds (...) them on the whole a good deal more sympathetic to his own ideas than the ‘modern atheism’, as he calls it, of Hobbes and Spinoza or the objectionable principles of ‘the mechanic and geometrical philosophers’ such as Newton. But his strongest and, I think, his most interesting claim is that neither Plato nor Aristotle admitted ‘an absolute actual existence of sensible or corporeal things’. (shrink)

: In Contra Academicos 3.11.24, Augustine responds to skepticism about the existence of the external world by arguing that what appears to be the world — as he terms things, the "quasi-earth" and "quasi-sky" — cannot be doubted. While some (e.g., M. Burnyeat and G. Matthews) interpret this passage as a subjectivist response to global skepticism, it is here argued that Augustine's debt to Epicurean epistemology and theology, especially as presented in Cicero's De Natura Deorum 1.25.69 - 1.26.74, provides the (...) basis for a much more plausible, realist interpretation of Augustine's argument.

This paper looks at the critical reception of two central claims of Peter Auriol’s theory of cognition: the claim that the objects of cognition have an apparent or objective being that resists reduction to the real being of objects, and the claim that there may be natural intuitive cognitions of nonexistent objects. These claims earned Auriol the criticism of his fellow Franciscans, Walter Chatton and Adam Wodeham. According to them, the theory of apparent being was what had led Auriol to (...) allow for intuitive cognitions of nonexistents, but the intuitive cognition of nonexistents, at its turn, led to scepticism. Modern commentators have offered similar readings of Auriol, but this paper argues, first, that the apparent being provides no special reason to think there could be intuitions of nonexistent objects, and second, that despite his idiosyncratic account of intuition, Auriol was no more vulnerable to scepticism than his critics.

External World Skepticism: The Deception of the Senses.

Zweifel und Gewissheit: Skeptische Debatten im Mittelalter (Philosophische Abhandlungen, Bd. 92).

In this book Han Thomas Adriaenssen offers the first comparative exploration of the sceptical reception of representationalism in medieval and early modern philosophy. Descartes is traditionally credited with inaugurating a new kind of scepticism by saying that the direct objects of perception are images in the mind, not external objects, but Adriaenssen shows that as early as the thirteenth century, critics had already found similar problems in Aquinas's theory of representation. He charts the attempts of philosophers in both periods to (...) grapple with these problems, and shows how in order to address the challenges of scepticism and representation, modern philosophers in the wake of Descartes often breathed new life into old ideas, remoulding them in ways that we are just beginning to understand. His book will be valuable for historians interested in the medieval background to early modern thought, and to medievalists looking at continuity with the early modern period. -/- . (shrink)

What am I thinking about? John Duns Scotus and Peter Aureol on intentional objects.

In L. Frank Baum's story, Ozma of Oz, which is a sequel to Baum's much more famous story, The Wonderful Wizard of Oz, Dorothy and her companion come upon a wound-down mechanical man bearing a label on which are printed the following words: Smith and Tinker's Patent Double-Action, Extra-Responsive, Thought-Creating Perfect-Talking MECHANICAL MAN Fitted with our Special Clock-Work Attachment Thinks, Speaks, Acts, and Does Everything but Live As Dorothy and her companion are made to discover when they wind up this (...) man, he is indeed capable of doing all the things of which his label boasts—acting, speaking and even thinking. But as Tik-Tok himself insists, and no one in the story casts doubt on the matter, he is not alive. (shrink)

This paper analyzes the theories of three representatives of Second Scholasticism, namely Francisco Suárez, sj, John Poinsot, op, and Francisco de Oviedo, sj, on the issue of the intuitive and abstractive cognition of the external senses. Based on a comparison of their theories, linked to the historical starting point of the debate in the first decades of the fourteenth century, the paper argues that the doctrinal and argumentative matrix of these authors’ texts is significantly ‘present’ in the Second Scholastics as (...) well. 1) As far as naturally produced sensation is concerned, all these authors, including Poinsot, follow the Scotistic justification of the natural infallibility of the external senses; 2) regarding the possibility of supernaturally caused objectless perception, Poinsot’s position can be labelled, surprisingly, Scotistic; 3) Suárez’s theory, although partly similar to the doctrine of the late Ockham, is an idiosyncratic stance; 4) Oviedo’s conception, even more distant from that of Ockham, can be characterized as ‘Auriolian’ and ‘Chattonian’.

The aim of this paper is to examine the medieval posterity of the Aristotelian and Pyrrhonian treatments of the infinite regress argument. We show that there are some possible Pyrrhonian elements in Autrecourt's epistemology when he argues that the truth of our principles is merely hypothetical. By contrast, Buridan's criticisms of Autrecourt rely heavily on Aristotelian material. Both exemplify a use of scepticism.

This essay deals with a selected part of an epistemological controversy provided by Tūsī in response to the skeptical arguments reported by Rāzī that is related to what might be called "intellectual skepticism," or skepticism regarding the judgments of the intellect, particularly in connection with self-evident principles. It will be shown that Rāzī has cited and exposed a position that seems to be no less than a medieval version of empiricism. Tūsī, in contrast, has presented us with a position that (...) rejects such empiricism. The comparative aim of this essay is to draw attention to some similarities as well as some points of divergence between the kind of skeptical debate we are focusing on here, and some relevant epistemological discussions in the later traditions in the West.

This book is a major contribution to the history of philosophy in the later medieval period (1250-1350). It focuses on cognitive theory, a subject of intense investigation during these years. In fact many of the issues that dominate philosophy of mind and epistemology today - intentionality, mental representation, scepticism, realism - were hotly debated in the later medieval period. The book offers a careful analysis of these debates, primarily through the work of Thomas Aquinas, John Olivi, and William Ockham. Each (...) of these figures attempts to reconceptualise cognition along direct realist lines, criticising in the process the standard Aristotelian account. Though of primary interest to medieval philosophers, the book presupposes no background knowledge of the medieval period, and will therefore interest a broader community of philosophers concerned with the origins of contemporary cognitive theory.

Skepticism: From Antiquity to the Present is an authoritative and up-to-date survey of the entire history of skepticism. Divided chronologically into ancient, medieval, renaissance, modern, and contemporary periods, and featuring 50 specially-commissioned chapters from leading philosophers, this comprehensive volume is the first of its kind.

St. Augustine is the bridge that links ancient philosophy and early Christian theology to the thought patterns of the Middle Ages. But the influence of Augustine's philosophy in general and his epistemology in particular extends far beyond medieval philosophy. Such modern philosophers as Descartes and Malebranche carry the stamp of Augustinism upon their philosophies. What is not so well known is that even some of the most original ideas of Berkeley and Kant can be found anticipated in Augustine.

This book offers a revisionary account of key epistemological concepts and doctrines of St Thomas Aquinas, particularly his concept of scientia, and proposes an interpretation of the purpose and composition of Aquinas's most mature and influential work, the Summa theologiae, which presents the scientia of sacred doctrine, i.e. Christian theology. Contrary to the standard interpretation of it as a work for neophytes in theology, Jenkins argues that it is in fact a pedagogical work intended as the culmination of philosophical and (...) theological studies of very gifted students. Jenkins considers our knowledge of the principles of a science. He argues that rational assent to the principles of sacred doctrine, the articles of faith, is due to the influence of grace on one's cognitive powers, because of which one is able immediately to apprehend these propositions as divinely revealed. His study will be of interest to readers in philosophy, theology and medieval studies. (shrink)

IN THE INTRODUCTION TO HIS STUDY of contemporary epistemology, Alvin Plantinga asserts that the “ahistoricism” of analytic philosophy has proven an impediment to progress in epistemology; what we need, he urges, is “history and hermeneutics.” In its turning to history, epistemology is beginning to resemble recent ethical theory, which has readily availed itself of the history of philosophy as a means of enriching its discourse and circumventing seemingly insoluble debates. There are other similarities between contemporary epistemology and recent ethical theory. (...) The standard division in contemporary epistemology pits internalism against externalism. The former demands that individuals have cognitive access to the justifying conditions of their belief and that the belief be formed in accord with appropriate rules. The latter drops the requirement of internal access but demands that a belief be formed by a process, reliably aimed at the production of truth. Internalism’s accentuation of epistemic rights and duties calls to mind ethical deontology, while the externalist emphasis on the production of true beliefs is akin to moral consequentialism. Lately, virtue epistemology has emerged to counter the two dominant theories of knowledge, just as virtue ethics arose as an alternative to deontology and utilitarianism. (shrink)

The first doctrine Peckham mentions as being under attack is of undoubtedly the TDI, according to which human beings are illuminated by "the unchangeable light" so as to attain the "eternal rules." This language of light and illumination is of course most closely associated with Augustine, but it permeates the entire Christian medieval tradition. Until Aquinas's time the TDI had played a prominent role in all the most influential medieval theories of knowledge, including those of Anselm, Albert the Great, Roger (...) Bacon, and, especially, Bonaventure. However, by the beginning of the fourteenth century the theory had fallen out of fashion. Indeed, the three best philosophers of the scholastic period--Aquinas, John Duns Scotus, and William Ockham--would all reject the theory in its standard form. Even by 1285 supporters of the TDI such as Peckham were evidently feeling rather defensive. It seems entirely plausible to attribute this attitude, in large part, to the influence of Aquinas's views on human knowledge. (shrink)
